 Configuring a development environment for Bun can take 10-30 minutes depending on your internet connection and computer speed. You will need ~10GB of free disk space for the repository and build artifacts.

-TL;DR: Ubuntu 22.04 is suggested.
-Bun currently requires `glibc >=2.32` in development which means if you're on Ubuntu 20.04 (glibc == 2.31), you may likely meet `error: undefined symbol: __libc_single_threaded `. You need to take extra configurations. Also, according to this [issue](https://github.com/llvm/llvm-project/issues/97314), LLVM 16 is no longer maintained on Ubuntu 24.04 (noble). And instead, you might want `brew` to install LLVM 16 for your Ubuntu 24.04.

+Production servers often read, upload, and write files to S3-compatible object storage services instead of the local filesystem. Historically, that means local filesystem APIs you use in development can't be used in production. When you use Bun, things are different.
+
+Bun provides fast, native bindings for interacting with S3-compatible object storage services. Bun's S3 API is designed to be simple and feel similar to fetch's `Response` and `Blob` APIs (like Bun's local filesystem APIs).
+
+```ts
+import { s3, write, S3 } from "bun";
+
+const metadata = await s3("123.json", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  // endpoint: "https://s3.us-east-1.amazonaws.com",
+});
+
+// Download from S3 as JSON
+const data = await metadata.json();
+
+// Upload to S3
+await write(metadata, JSON.stringify({ name: "John", age: 30 }));
+
+// Presign a URL (synchronous - no network request needed)
+const url = metadata.presign({
+  acl: "public-read",
+  expiresIn: 60 * 60 * 24, // 1 day
+});
+```
+
+S3 is the [de facto standard](https://en.wikipedia.org/wiki/De_facto_standard) internet filesystem. You can use Bun's S3 API with S3-compatible storage services like:
+
+- AWS S3
+- Cloudflare R2
+- DigitalOcean Spaces
+- MinIO
+- Backblaze B2
+- ...and any other S3-compatible storage service
+
+## Basic Usage
+
+There are several ways to interact with Bun's S3 API.
+
+### Using `Bun.s3()`
+
+The `s3()` helper function is used to create one-off `S3File` instances for a single file.
+
+```ts
+import { s3 } from "bun";
+
+// Using the s3() helper
+const s3file = s3("my-file.txt", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  // endpoint: "https://s3.us-east-1.amazonaws.com", // optional
+  // endpoint: "https://<account-id>.r2.cloudflarestorage.com", // Cloudflare R2
+  // endpoint: "https://<region>.digitaloceanspaces.com", // DigitalOcean Spaces
+  // endpoint: "http://localhost:9000", // MinIO
+});
+```
+
+### Reading Files
+
+You can read files from S3 using similar methods to Bun's file system APIs:
+
+```ts
+// Read an S3File as text
+const text = await s3file.text();
+
+// Read an S3File as JSON
+const json = await s3file.json();
+
+// Read an S3File as an ArrayBuffer
+const buffer = await s3file.arrayBuffer();
+
+// Get only the first 1024 bytes
+const partial = await s3file.slice(0, 1024).text();
+
+// Stream the file
+const stream = s3file.stream();
+for await (const chunk of stream) {
+  console.log(chunk);
+}
+```
+
+## Writing Files
+
+Writing to S3 is just as simple:
+
+```ts
+// Write a string (replacing the file)
+await s3file.write("Hello World!");
+
+// Write with content type
+await s3file.write(JSON.stringify({ name: "John", age: 30 }), {
+  type: "application/json",
+});
+
+// Write using a writer (streaming)
+const writer = s3file.writer({ type: "application/json" });
+writer.write("Hello");
+writer.write(" World!");
+await writer.end();
+
+// Write using Bun.write
+await Bun.write(s3file, "Hello World!");
+```
+
+### Working with large files (streams)
+
+Bun automatically handles multipart uploads for large files and provides streaming capabilities. The same API that works for local files also works for S3 files.
+
+```ts
+// Write a large file
+const bigFile = Buffer.alloc(10 * 1024 * 1024); // 10MB
+const writer = s3file.writer({
+  // Automatically retry on network errors up to 3 times
+  retry: 3,
+
+  // Queue up to 10 requests at a time
+  queueSize: 10,
+
+  // Upload in 5 MB chunks
+  partSize: 5 * 1024 * 1024,
+});
+for (let i = 0; i < 10; i++) {
+  await writer.write(bigFile);
+}
+await writer.end();
+```
+
+## Presigning URLs
+
+When your production service needs to let users upload files to your server, it's often more reliable for the user to upload directly to S3 instead of your server acting as an intermediary.
+
+To facilitate this, you can presign URLs for S3 files. This generates a URL with a signature that allows a user to securely upload that specific file to S3, without exposing your credentials or granting them unnecessary access to your bucket.
+
+```ts
+// Generate a presigned URL that expires in 24 hours (default)
+const url = s3file.presign();
+
+// Custom expiration time (in seconds)
+const url2 = s3file.presign({ expiresIn: 3600 }); // 1 hour
+
+// Using static method
+const url3 = Bun.S3.presign("my-file.txt", {
+  bucket: "my-bucket",
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  // endpoint: "https://s3.us-east-1.amazonaws.com",
+  // endpoint: "https://<account-id>.r2.cloudflarestorage.com", // Cloudflare R2
+  expiresIn: 3600,
+});
+```
+
+### Setting ACLs
+
+To set an ACL (access control list) on a presigned URL, pass the `acl` option:
+
+```ts
+const url = s3file.presign({
+  acl: "public-read",
+  expiresIn: 3600,
+});
+```
+
+You can pass any of the following ACLs:
+
+| ACL                           | Explanation                                                         |
+| ----------------------------- | ------------------------------------------------------------------- |
+| `"public-read"`               | The object is readable by the public.                               |
+| `"private"`                   | The object is readable only by the bucket owner.                    |
+| `"public-read-write"`         | The object is readable and writable by the public.                  |
+| `"authenticated-read"`        | The object is readable by the bucket owner and authenticated users. |
+| `"aws-exec-read"`             | The object is readable by the AWS account that made the request.    |
+| `"bucket-owner-read"`         | The object is readable by the bucket owner.                         |
+| `"bucket-owner-full-control"` | The object is readable and writable by the bucket owner.            |
+| `"log-delivery-write"`        | The object is writable by AWS services used for log delivery.       |
+
+### Expiring URLs
+
+To set an expiration time for a presigned URL, pass the `expiresIn` option.
+
+```ts
+const url = s3file.presign({
+  // Seconds
+  expiresIn: 3600, // 1 hour
+});
+```
+
+### `method`
+
+To set the HTTP method for a presigned URL, pass the `method` option.
+
+```ts
+const url = s3file.presign({
+  method: "PUT",
+  // method: "DELETE",
+  // method: "GET",
+  // method: "HEAD",
+  // method: "POST",
+  // method: "PUT",
+});
+```
+
+### `new Response(S3File)`
+
+To quickly redirect users to a presigned URL for an S3 file, you can pass an `S3File` instance to a `Response` object as the body.
+
+```ts
+const response = new Response(s3file);
+console.log(response);
+```
+
+This will automatically redirect the user to the presigned URL for the S3 file, saving you the memory, time, and bandwidth cost of downloading the file to your server and sending it back to the user.
+
+```ts
+Response (0 KB) {
+  ok: false,
+  url: "",
+  status: 302,

+## Support for S3-Compatible Services
+
+Bun's S3 implementation works with any S3-compatible storage service. Just specify the appropriate endpoint:
+
+```ts
+import { s3 } from "bun";
+
+// CloudFlare R2
+const r2file = s3("my-file.txt", {
+  accessKeyId: "access-key",
+  secretAccessKey: "secret-key",
+  bucket: "my-bucket",
+  endpoint: "https://<account-id>.r2.cloudflarestorage.com",
+});
+
+// DigitalOcean Spaces
+const spacesFile = s3("my-file.txt", {
+  accessKeyId: "access-key",
+  secretAccessKey: "secret-key",
+  bucket: "my-bucket",
+  endpoint: "https://<region>.digitaloceanspaces.com",
+});
+
+// MinIO
+const minioFile = s3("my-file.txt", {
+  accessKeyId: "access-key",
+  secretAccessKey: "secret-key",
+  bucket: "my-bucket",
+  endpoint: "http://localhost:9000",
+});
+```
+
+## Credentials
+
+Credentials are one of the hardest parts of using S3, and we've tried to make it as easy as possible. By default, Bun reads the following environment variables for credentials.
+
+| Option name       | Environment variable   |
+| ----------------- | ---------------------- |
+| `accessKeyId`     | `S3_ACCESS_KEY_ID`     |
+| `secretAccessKey` | `S3_SECRET_ACCESS_KEY` |
+| `region`          | `S3_REGION`            |
+| `endpoint`        | `S3_ENDPOINT`          |
+| `bucket`          | `S3_BUCKET`            |
+| `sessionToken`    | `S3_SESSION_TOKEN`     |
+
+If the `S3_*` environment variable is not set, Bun will also check for the `AWS_*` environment variable, for each of the above options.
+
+| Option name       | Fallback environment variable |
+| ----------------- | ----------------------------- |
+| `accessKeyId`     | `AWS_ACCESS_KEY_ID`           |
+| `secretAccessKey` | `AWS_SECRET_ACCESS_KEY`       |
+| `region`          | `AWS_REGION`                  |
+| `endpoint`        | `AWS_ENDPOINT`                |
+| `bucket`          | `AWS_BUCKET`                  |
+| `sessionToken`    | `AWS_SESSION_TOKEN`           |
+
+These environment variables are read from [`.env` files](/docs/runtime/env) or from the process environment at initialization time (`process.env` is not used for this).
+
+These defaults are overriden by the options you pass to `s3(credentials)`, `new Bun.S3(credentials)`, or any of the methods that accept credentials. So if, for example, you use the same credentials for different buckets, you can set the credentials once in your `.env` file and then pass `bucket: "my-bucket"` to the `s3()` helper function without having to specify all the credentials again.
+
+### `S3` Buckets
+
+Passing around all of these credentials can be cumbersome. To make it easier, you can create a `S3` bucket instance.
+
+```ts
+import { S3 } from "bun";
+
+const bucket = new S3({
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  // sessionToken: "..."
+  endpoint: "https://s3.us-east-1.amazonaws.com",
+  // endpoint: "https://<account-id>.r2.cloudflarestorage.com", // Cloudflare R2
+  // endpoint: "http://localhost:9000", // MinIO
+});
+
+// bucket is a function that creates `S3File` instances (lazy)
+const file = bucket("my-file.txt");
+
+// Write to S3
+await file.write("Hello World!");
+
+// Read from S3
+const text = await file.text();
+
+// Write using a Response
+await file.write(new Response("Hello World!"));
+
+// Presign a URL
+const url = file.presign({
+  expiresIn: 60 * 60 * 24, // 1 day
+  acl: "public-read",
+});
+
+// Delete the file
+await file.unlink();
+```
+
+#### Read a file from an `S3` bucket
+
+The `S3` bucket instance is itself a function that creates `S3File` instances. It provides a more convenient API for interacting with S3.
+
+```ts
+const s3file = bucket("my-file.txt");
+const text = await s3file.text();
+const json = await s3file.json();
+const bytes = await s3file.bytes();
+const arrayBuffer = await s3file.arrayBuffer();
+```
+
+#### Write a file to S3
+
+To write a file to the bucket, you can use the `write` method.
+
+```ts
+const bucket = new Bun.S3({
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  endpoint: "https://s3.us-east-1.amazonaws.com",
+  bucket: "my-bucket",
+});
+await bucket.write("my-file.txt", "Hello World!");
+await bucket.write("my-file.txt", new Response("Hello World!"));
+```
+
+You can also call `.write` on the `S3File` instance created by the `S3` bucket instance.
+
+```ts
+const s3file = bucket("my-file.txt");
+await s3file.write("Hello World!", {
+  type: "text/plain",
+});
+await s3file.write(new Response("Hello World!"));
+```
+
+#### Delete a file from S3
+
+To delete a file from the bucket, you can use the `delete` method.
+
+```ts
+const bucket = new Bun.S3({
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+});
+
+await bucket.delete("my-file.txt");
+```
+
+You can also use the `unlink` method, which is an alias for `delete`.
+
+```ts
+// "delete" and "unlink" are aliases of each other.
+await bucket.unlink("my-file.txt");
+```
+
+## `S3File`
+
+`S3File` instances are created by calling the `S3` instance method or the `s3()` helper function. Like `Bun.file()`, `S3File` instances are lazy. They don't refer to something that necessarily exists at the time of creation. That's why all the methods that don't involve network requests are fully synchronous.
+
+```ts
+interface S3File extends Blob {
+  slice(start: number, end?: number): S3File;
+  exists(): Promise<boolean>;
+  unlink(): Promise<void>;
+  presign(options: S3Options): string;
+  text(): Promise<string>;
+  json(): Promise<any>;
+  bytes(): Promise<Uint8Array>;
+  arrayBuffer(): Promise<ArrayBuffer>;
+  stream(options: S3Options): ReadableStream;
+  write(
+    data:
+      | string
+      | Uint8Array
+      | ArrayBuffer
+      | Blob
+      | ReadableStream
+      | Response
+      | Request,
+    options?: BlobPropertyBag,
+  ): Promise<void>;
+
+  readonly size: Promise<number>;
+
+  // ... more omitted for brevity
+}
+```
+
+Like `Bun.file()`, `S3File` extends [`Blob`](https://developer.mozilla.org/en-US/docs/Web/API/Blob), so all the methods that are available on `Blob` are also available on `S3File`. The same API for reading data from a local file is also available for reading data from S3.
+
+| Method                       | Output           |
+| ---------------------------- | ---------------- |
+| `await s3File.text()`        | `string`         |
+| `await s3File.bytes()`       | `Uint8Array`     |
+| `await s3File.json()`        | `JSON`           |
+| `await s3File.stream()`      | `ReadableStream` |
+| `await s3File.arrayBuffer()` | `ArrayBuffer`    |
+
+That means using `S3File` instances with `fetch()`, `Response`, and other web APIs that accept `Blob` instances just works.
+
+### Partial reads
+
+To read a partial range of a file, you can use the `slice` method.
+
+```ts
+const partial = s3file.slice(0, 1024);
+
+// Read the partial range as a Uint8Array
+const bytes = await partial.bytes();
+
+// Read the partial range as a string
+const text = await partial.text();
+```
+
+Internally, this works by using the HTTP `Range` header to request only the bytes you want. This `slice` method is the same as [`Blob.prototype.slice`](https://developer.mozilla.org/en-US/docs/Web/API/Blob/slice).
+
+## Error codes
+
+When Bun's S3 API throws an error, it will have a `code` property that matches one of the following values:
+
+- `ERR_S3_MISSING_CREDENTIALS`
+- `ERR_S3_INVALID_METHOD`
+- `ERR_S3_INVALID_PATH`
+- `ERR_S3_INVALID_ENDPOINT`
+- `ERR_S3_INVALID_SIGNATURE`
+- `ERR_S3_INVALID_SESSION_TOKEN`
+
+When the S3 Object Storage service returns an error (that is, not Bun), it will be an `S3Error` instance (an `Error` instance with the name `"S3Error"`).
+
+## `S3` static methods
+
+The `S3` class provides several static methods for interacting with S3.
+
+### `S3.presign`
+
+To generate a presigned URL for an S3 file, you can use the `S3.presign` method.
+
+```ts
+import { S3 } from "bun";
+
+const url = S3.presign("my-file.txt", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  expiresIn: 3600,
+  // endpoint: "https://s3.us-east-1.amazonaws.com",
+  // endpoint: "https://<account-id>.r2.cloudflarestorage.com", // Cloudflare R2
+});
+```
+
+This is the same as `S3File.prototype.presign` and `new S3(credentials).presign`, as a static method on the `S3` class.
+
+### `S3.exists`
+
+To check if an S3 file exists, you can use the `S3.exists` method.
+
+```ts
+import { S3 } from "bun";
+
+const exists = await S3.exists("my-file.txt", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  // endpoint: "https://s3.us-east-1.amazonaws.com",
+});
+```
+
+The same method also works on `S3File` instances.
+
+```ts
+const s3file = Bun.s3("my-file.txt", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+});
+const exists = await s3file.exists();
+```
+
+### `S3.size`
+
+To get the size of an S3 file, you can use the `S3.size` method.
+
+```ts
+import { S3 } from "bun";
+const size = await S3.size("my-file.txt", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  // endpoint: "https://s3.us-east-1.amazonaws.com",
+});
+```
+
+### `S3.unlink`
+
+To delete an S3 file, you can use the `S3.unlink` method.
+
+```ts
+import { S3 } from "bun";
+
+await S3.unlink("my-file.txt", {
+  accessKeyId: "your-access-key",
+  secretAccessKey: "your-secret-key",
+  bucket: "my-bucket",
+  // endpoint: "https://s3.us-east-1.amazonaws.com",
+});
+```
+
+## s3:// protocol
+
+To make it easier to use the same code for local files and S3 files, the `s3://` protocol is supported in `fetch` and `Bun.file()`.
+
+```ts
+const response = await fetch("s3://my-bucket/my-file.txt");
+const file = Bun.file("s3://my-bucket/my-file.txt");
+```
+
+This is the equivalent of calling `Bun.s3("my-file.txt", { bucket: "my-bucket" })`.
+
+This `s3://` protocol exists to make it easier to use the same code for local files and S3 files.

+## Lifecycle hooks
+
+Plugins can register callbacks to be run at various points in the lifecycle of a bundle:
+
+- [`onStart()`](#onstart): Run once the bundler has started a bundle
+- [`onResolve()`](#onresolve): Run before a module is resolved
+- [`onLoad()`](#onload): Run before a module is loaded.
+- [`onBeforeParse()`](#onbeforeparse): Run zero-copy native addons in the parser thread before a file is parsed.

+  onStart(callback: () => void): void;

+      namespace?: string;
+    } | void,
+  ) => void;
+  onLoad: (
+    args: { filter: RegExp; namespace?: string },
+    defer: () => Promise<void>,
+    callback: (args: { path: string }) => {
+      loader?: Loader;
+      contents?: string;
+      exports?: Record<string, any>;

+## Plugin lifecycle
+
+### Namespaces
+
+`onLoad` and `onResolve` accept an optional `namespace` string. What is a namespace?
+
+Every module has a namespace. Namespaces are used to prefix the import in transpiled code; for instance, a loader with a `filter: /\.yaml$/` and `namespace: "yaml:"` will transform an import from `./myfile.yaml` into `yaml:./myfile.yaml`.
+
+The default namespace is `"file"` and it is not necessary to specify it, for instance: `import myModule from "./my-module.ts"` is the same as `import myModule from "file:./my-module.ts"`.
+
+Other common namespaces are:
+
+- `"bun"`: for Bun-specific modules (e.g. `"bun:test"`, `"bun:sqlite"`)
+- `"node"`: for Node.js modules (e.g. `"node:fs"`, `"node:path"`)
+
+### `onStart`
+
+```ts
+onStart(callback: () => void): Promise<void> | void;
+```
+
+Registers a callback to be run when the bundler starts a new bundle.
+
+```ts
+import { plugin } from "bun";
+
+plugin({
+  name: "onStart example",
+
+  setup(build) {
+    build.onStart(() => {
+      console.log("Bundle started!");
+    });
+  },
+});
+```
+
+The callback can return a `Promise`. After the bundle process has initialized, the bundler waits until all `onStart()` callbacks have completed before continuing.
+
+For example:
+
+```ts
+const result = await Bun.build({
+  entrypoints: ["./app.ts"],
+  outdir: "./dist",
+  sourcemap: "external",
+  plugins: [
+    {
+      name: "Sleep for 10 seconds",
+      setup(build) {
+        build.onStart(async () => {
+          await Bunlog.sleep(10_000);
+        });
+      },
+    },
+    {
+      name: "Log bundle time to a file",
+      setup(build) {
+        build.onStart(async () => {
+          const now = Date.now();
+          await Bun.$`echo ${now} > bundle-time.txt`;
+        });
+      },
+    },
+  ],
+});
+```
+
+In the above example, Bun will wait until the first `onStart()` (sleeping for 10 seconds) has completed, _as well as_ the second `onStart()` (writing the bundle time to a file).
+
+Note that `onStart()` callbacks (like every other lifecycle callback) do not have the ability to modify the `build.config` object. If you want to mutate `build.config`, you must do so directly in the `setup()` function.
+
+### `onResolve`
+
+```ts
+onResolve(
+  args: { filter: RegExp; namespace?: string },
+  callback: (args: { path: string; importer: string }) => {
+    path: string;
+    namespace?: string;
+  } | void,
+): void;
+```
+
+To bundle your project, Bun walks down the dependency tree of all modules in your project. For each imported module, Bun actually has to find and read that module. The "finding" part is known as "resolving" a module.
+
+The `onResolve()` plugin lifecycle callback allows you to configure how a module is resolved.
+
+The first argument to `onResolve()` is an object with a `filter` and [`namespace`](#what-is-a-namespace) property. The filter is a regular expression which is run on the import string. Effectively, these allow you to filter which modules your custom resolution logic will apply to.
+
+The second argument to `onResolve()` is a callback which is run for each module import Bun finds that matches the `filter` and `namespace` defined in the first argument.
+
+The callback receives as input the _path_ to the matching module. The callback can return a _new path_ for the module. Bun will read the contents of the _new path_ and parse it as a module.
+
+For example, redirecting all imports to `images/` to `./public/images/`:
+
+```ts
+import { plugin } from "bun";
+
+plugin({
+  name: "onResolve example",
+  setup(build) {
+    build.onResolve({ filter: /.*/, namespace: "file" }, args => {
+      if (args.path.startsWith("images/")) {
+        return {
+          path: args.path.replace("images/", "./public/images/"),
+        };
+      }
+    });
+  },
+});
+```
+
+### `onLoad`
+
+```ts
+onLoad(
+  args: { filter: RegExp; namespace?: string },
+  defer: () => Promise<void>,
+  callback: (args: { path: string, importer: string, namespace: string, kind: ImportKind  }) => {
+    loader?: Loader;
+    contents?: string;
+    exports?: Record<string, any>;
+  },
+): void;
+```
+
+After Bun's bundler has resolved a module, it needs to read the contents of the module and parse it.
+
+The `onLoad()` plugin lifecycle callback allows you to modify the _contents_ of a module before it is read and parsed by Bun.
+
+Like `onResolve()`, the first argument to `onLoad()` allows you to filter which modules this invocation of `onLoad()` will apply to.
+
+The second argument to `onLoad()` is a callback which is run for each matching module _before_ Bun loads the contents of the module into memory.
+
+This callback receives as input the _path_ to the matching module, the _importer_ of the module (the module that imported the module), the _namespace_ of the module, and the _kind_ of the module.
+
+The callback can return a new `contents` string for the module as well as a new `loader`.
+
+For example:
+
+```ts
+import { plugin } from "bun";
+
+const envPlugin: BunPlugin = {
+  name: "env plugin",
+  setup(build) {
+    build.onLoad({ filter: /env/, namespace: "file" }, args => {
+      return {
+        contents: `export default ${JSON.stringify(process.env)}`,
+        loader: "js",
+      };
+    });
+  },
+});
+
+Bun.build({
+  entrypoints: ["./app.ts"],
+  outdir: "./dist",
+  plugins: [envPlugin],
+});
+
+// import env from "env"
+// env.FOO === "bar"
+```
+
+This plugin will transform all imports of the form `import env from "env"` into a JavaScript module that exports the current environment variables.
+
+#### `.defer()`
+
+One of the arguments passed to the `onLoad` callback is a `defer` function. This function returns a `Promise` that is resolved when all _other_ modules have been loaded.
+
+This allows you to delay execution of the `onLoad` callback until all other modules have been loaded.
+
+This is useful for returning contents of a module that depends on other modules.
+
+##### Example: tracking and reporting unused exports
+
+```ts
+import { plugin } from "bun";
+
+plugin({
+  name: "track imports",
+  setup(build) {
+    const transpiler = new Bun.Transpiler();
+
+    let trackedImports: Record<string, number> = {};
+
+    // Each module that goes through this onLoad callback
+    // will record its imports in `trackedImports`
+    build.onLoad({ filter: /\.ts/ }, async ({ path }) => {
+      const contents = await Bun.file(path).arrayBuffer();
+
+      const imports = transpiler.scanImports(contents);
+
+      for (const i of imports) {
+        trackedImports[i.path] = (trackedImports[i.path] || 0) + 1;
+      }
+
+      return undefined;
+    });
+
+    build.onLoad({ filter: /stats\.json/ }, async ({ defer }) => {
+      // Wait for all files to be loaded, ensuring
+      // that every file goes through the above `onLoad()` function
+      // and their imports tracked
+      await defer();
+
+      // Emit JSON containing the stats of each import
+      return {
+        contents: `export default ${JSON.stringify(trackedImports)}`,
+        loader: "json",
+      };
+    });
+  },
+});
+```
+
+Note that the `.defer()` function currently has the limitation that it can only be called once per `onLoad` callback.
+
+## Native plugins
+
+One of the reasons why Bun's bundler is so fast is that it is written in native code and leverages multi-threading to load and parse modules in parallel.
+
+However, one limitation of plugins written in JavaScript is that JavaScript itself is single-threaded.
+
+Native plugins are written as [NAPI](/docs/node-api) modules and can be run on multiple threads. This allows native plugins to run much faster than JavaScript plugins.
+
+In addition, native plugins can skip unnecessary work such as the UTF-8 -> UTF-16 conversion needed to pass strings to JavaScript.
+
+These are the following lifecycle hooks which are available to native plugins:
+
+- [`onBeforeParse()`](#onbeforeparse): Called on any thread before a file is parsed by Bun's bundler.
+
+Native plugins are NAPI modules which expose lifecycle hooks as C ABI functions.
+
+To create a native plugin, you must export a C ABI function which matches the signature of the native lifecycle hook you want to implement.
+
+### Creating a native plugin in Rust
+
+Native plugins are NAPI modules which expose lifecycle hooks as C ABI functions.
+
+To create a native plugin, you must export a C ABI function which matches the signature of the native lifecycle hook you want to implement.
+
+```bash
+bun add -g @napi-rs/cli
+napi new
+```
+
+Then install this crate:
+
+```bash
+cargo add bun-native-plugin
+```
+
+Now, inside the `lib.rs` file, we'll use the `bun_native_plugin::bun` proc macro to define a function which
+will implement our native plugin.
+
+Here's an example implementing the `onBeforeParse` hook:
+
+```rs
+use bun_native_plugin::{define_bun_plugin, OnBeforeParse, bun, Result, anyhow, BunLoader};
+use napi_derive::napi;
+
+/// Define the plugin and its name
+define_bun_plugin!("replace-foo-with-bar");
+
+/// Here we'll implement `onBeforeParse` with code that replaces all occurrences of
+/// `foo` with `bar`.
+///
+/// We use the #[bun] macro to generate some of the boilerplate code.
+///
+/// The argument of the function (`handle: &mut OnBeforeParse`) tells
+/// the macro that this function implements the `onBeforeParse` hook.
+#[bun]
+pub fn replace_foo_with_bar(handle: &mut OnBeforeParse) -> Result<()> {
+  // Fetch the input source code.
+  let input_source_code = handle.input_source_code()?;
+
+  // Get the Loader for the file
+  let loader = handle.output_loader();
+
+
+  let output_source_code = input_source_code.replace("foo", "bar");
+
+  handle.set_output_source_code(output_source_code, BunLoader::BUN_LOADER_JSX);
+
+  Ok(())
+}
+```
+
+And to use it in Bun.build():
+
+```typescript
+import myNativeAddon from "./my-native-addon";
+Bun.build({
+  entrypoints: ["./app.tsx"],
+  plugins: [
+    {
+      name: "my-plugin",
+
+      setup(build) {
+        build.onBeforeParse(
+          {
+            namespace: "file",
+            filter: "**/*.tsx",
+          },
+          {
+            napiModule: myNativeAddon,
+            symbol: "replace_foo_with_bar",
+            // external: myNativeAddon.getSharedState()
+          },
+        );
+      },
+    },
+  ],
+});
+```
+
+### `onBeforeParse`
+
+```ts
+onBeforeParse(
+  args: { filter: RegExp; namespace?: string },
+  callback: { napiModule: NapiModule; symbol: string; external?: unknown },
+): void;
+```
+
+This lifecycle callback is run immediately before a file is parsed by Bun's bundler.
+
+As input, it receives the file's contents and can optionally return new source code.
+
+This callback can be called from any thread and so the napi module implementation must be thread-safe.

+
+Bun's [Plugin API](/docs/runtime/plugins) lets you add custom loaders to your project. The `test.preload` option in `bunfig.toml` lets you configure your loader to start before your tests run.
+
+Firstly, install `@testing-library/svelte`, `svelte`, and `@happy-dom/global-registrator`.
+
+```bash
+$ bun add @testing-library/svelte svelte@4 @happy-dom/global-registrator
+```
+
+Then, save this plugin in your project.
+
+```ts#svelte-loader.js
+import { plugin } from "bun";
+import { compile } from "svelte/compiler";
+import { readFileSync } from "fs";
+import { beforeEach, afterEach } from "bun:test";
+import { GlobalRegistrator } from "@happy-dom/global-registrator";
+
+beforeEach(async () => {
+  await GlobalRegistrator.register();
+});
+
+afterEach(async () => {
+  await GlobalRegistrator.unregister();
+});
+
+plugin({
+  name: "svelte loader",
+  setup(builder) {
+    builder.onLoad({ filter: /\.svelte(\?[^.]+)?$/ }, ({ path }) => {
+      try {
+        const source = readFileSync(
+          path.substring(
+            0,
+            path.includes("?") ? path.indexOf("?") : path.length
+          ),
+          "utf-8"
+        );
+
+        const result = compile(source, {
+          filename: path,
+          generate: "client",
+          dev: false,
+        });
+
+        return {
+          contents: result.js.code,
+          loader: "js",
+        };
+      } catch (err) {
+        throw new Error(`Failed to compile Svelte component: ${err.message}`);
+      }
+    });
+  },
+});
+
+```
+
+---
+
+Add this to `bunfig.toml` to tell Bun to preload the plugin, so it loads before your tests run.
+
+```toml#bunfig.toml
+[test]
+# Tell Bun to load this plugin before your tests run
+preload = ["./svelte-loader.js"]
+
+# This also works:
+# test.preload = ["./svelte-loader.js"]
+```
+
+---
+
+Add an example `.svelte` file in your project.
+
+```html#Counter.svelte
+<script>
+  export let initialCount = 0;
+  let count = initialCount;
+</script>
+
+<button on:click={() => (count += 1)}>+1</button>
+```
+
+---
+
+Now you can `import` or `require` `*.svelte` files in your tests, and it will load the Svelte component as a JavaScript module.
+
+```ts#hello-svelte.test.ts
+import { test, expect } from "bun:test";
+import { render, fireEvent } from "@testing-library/svelte";
+import Counter from "./Counter.svelte";
+
+test("Counter increments when clicked", async () => {
+  const { getByText, component } = render(Counter);
+  const button = getByText("+1");
+
+  // Initial state
+  expect(component.$$.ctx[0]).toBe(0); // initialCount is the first prop
+
+  // Click the increment button
+  await fireEvent.click(button);
+
+  // Check the new state
+  expect(component.$$.ctx[0]).toBe(1);
+});

+This document is for maintainers and contributors to Bun, and describes internal implementation details.
+
+{% /callout %}
+
+The new bindings generator, introduced to the codebase in Dec 2024, scans for
+`*.bind.ts` to find function and class definition, and generates glue code to
+interop between JavaScript and native code.
+
+There are currently other code generators and systems that achieve similar
+purposes. The following will all eventually be completely phased out in favor of
+this one:
+
+- "Classes generator", converting `*.classes.ts` for custom classes.
+- "JS2Native", allowing ad-hoc calls from `src/js` to native code.
+
+## Creating JS Functions in Zig
+
+Given a file implementing a simple function, such as `add`
+
+```zig#src/bun.js/math.zig
+pub fn add(global: *JSC.JSGlobalObject, a: i32, b: i32) !i32 {
+    return std.math.add(i32, a, b) catch {
+        // Binding functions can return `error.OutOfMemory` and `error.JSError`.
+        // Others like `error.Overflow` from `std.math.add` must be converted.
+        // Remember to be descriptive.
+        return global.throwPretty("Integer overflow while adding", .{});
+    };
+}
+
+const gen = bun.gen.math; // "math" being this file's basename
+
+const std = @import("std");
+const bun = @import("root").bun;
+const JSC = bun.JSC;
+```
+
+Then describe the API schema using a `.bind.ts` function. The binding file goes next to the Zig file.
+
+```ts#src/bun.js/math.bind.ts
+import { t, fn } from 'bindgen';
+
+export const add = fn({
+  args: {
+    global: t.globalObject,
+    a: t.i32,
+    b: t.i32.default(1),
+  },
+  ret: t.i32,
+});
+```
+
+This function declaration is equivalent to:
+
+```ts
+/**
+ * Throws if zero arguments are provided.
+ * Wraps out of range numbers using modulo.
+ */
+declare function add(a: number, b: number = 1): number;
+```
+
+The code generator will provide `bun.gen.math.jsAdd`, which is the native
+function implementation. To pass to JavaScript, use
+`bun.gen.math.createAddCallback(global)`. JS files in `src/js/` may use
+`$bindgenFn("math.bind.ts", "add")` to get a handle to the implementation.
+
+## Strings
+
+The type for receiving strings is one of [`t.DOMString`](https://webidl.spec.whatwg.org/#idl-DOMString), [`t.ByteString`](https://webidl.spec.whatwg.org/#idl-ByteString), and [`t.USVString`](https://webidl.spec.whatwg.org/#idl-USVString). These map directly to their WebIDL counterparts, and have slightly different conversion logic. Bindgen will pass BunString to native code in all cases.
+
+When in doubt, use DOMString.
+
+`t.UTF8String` can be used in place of `t.DOMString`, but will call `bun.String.toUTF8`. The native callback gets `[]const u8` (WTF-8 data) passed to native code, freeing it after the function returns.
+
+TLDRs from WebIDL spec:
+
+- ByteString can only contain valid latin1 characters. It is not safe to assume bun.String is already in 8-bit format, but it is extremely likely.
+- USVString will not contain invalid surrogate pairs, aka text that can be represented correctly in UTF-8.
+- DOMString is the loosest but also most recommended strategy.
+
+## Function Variants
+
+A `variants` can specify multiple variants (also known as overloads).
+
+```ts#src/bun.js/math.bind.ts
+import { t, fn } from 'bindgen';
+
+export const action = fn({
+  variants: [
+    {
+      args: {
+        a: t.i32,
+      },
+      ret: t.i32,
+    },
+    {
+      args: {
+        a: t.DOMString,
+      },
+      ret: t.DOMString,
+    },
+  ]
+});
+```
+
+In Zig, each variant gets a number, based on the order the schema defines.
+
+```zig
+fn action1(a: i32) i32 {
+  return a;
+}
+
+fn action2(a: bun.String) bun.String {
+  return a;
+}
+```
+
+## `t.dictionary`
+
+A `dictionary` is a definition for a JavaScript object, typically as a function inputs. For function outputs, it is usually a smarter idea to declare a class type to add functions and destructuring.
+
+## Enumerations
+
+To use [WebIDL's enumeration](https://webidl.spec.whatwg.org/#idl-enums) type, use either:
+
+- `t.stringEnum`: Create and codegen a new enum type.
+- `t.zigEnum`: Derive a bindgen type off of an existing enum in the codebase.
+
+An example of `stringEnum` as used in `fmt.zig` / `bun:internal-for-testing`
+
+```ts
+export const Formatter = t.stringEnum(
+  "highlight-javascript",
+  "escape-powershell",
+);
+
+export const fmtString = fn({
+  args: {
+    global: t.globalObject,
+    code: t.UTF8String,
+    formatter: Formatter,
+  },
+  ret: t.DOMString,
+});
+```
+
+WebIDL strongly encourages using kebab case for enumeration values, to be consistent with existing Web APIs.
+
+### Deriving enums from Zig code
+
+TODO: zigEnum
+
+## `t.oneOf`
+
+A `oneOf` is a union between two or more types. It is represented by `union(enum)` in Zig.
+
+TODO:
+
+## Attributes
+
+There are set of attributes that can be chained onto `t.*` types. On all types there are:
+
+- `.required`, in dictionary parameters only
+- `.optional`, in function arguments only
+- `.default(T)`
+
+When a value is optional, it is lowered to a Zig optional.
+
+Depending on the type, there are more attributes available. See the type definitions in auto-complete for more details. Note that one of the above three can only be applied, and they must be applied at the end.
+
+### Integer Attributes
+
+Integer types allow customizing the overflow behavior with `clamp` or `enforceRange`
+
+```ts
+import { t, fn } from "bindgen";
+
+export const add = fn({
+  args: {
+    global: t.globalObject,
+    // enforce in i32 range
+    a: t.i32.enforceRange(),
+    // clamp to u16 range
+    b: t.u16,
+    // enforce in arbitrary range, with a default if not provided
+    c: t.i32.enforceRange(0, 1000).default(5),
+    // clamp to arbitrary range, or null
+    d: t.u16.clamp(0, 10).optional,
+  },
+  ret: t.i32,
+});
+```
+
+Various Node.js validator functions such as `validateInteger`, `validateNumber`, and more are available. Use these when implementing Node.js APIs, so the error messages match 1:1 what Node would do.
+
+Unlike `enforceRange`, which is taken from WebIDL, `validate*` functions are much more strict on the input they accept. For example, Node's numerical validator check `typeof value === 'number'`, while WebIDL uses `ToNumber` for lossy conversion.
+
+```ts
+import { t, fn } from "bindgen";
+
+export const add = fn({
+  args: {
+    global: t.globalObject,
+    // throw if not given a number
+    a: t.f64.validateNumber(),
+    // valid in i32 range
+    a: t.i32.validateInt32(),
+    // f64 within safe integer range
+    b: t.f64.validateInteger(),
+    // f64 in given range
+    c: t.f64.validateNumber(-10000, 10000),
+  },
+  ret: t.i32,
+});

 This plugin will transform all imports of the form `import env from "env"` into a JavaScript module that exports the current environment variables.
-
-#### `.defer()`
-
-One of the arguments passed to the `onLoad` callback is a `defer` function. This function returns a `Promise` that is resolved when all _other_ modules have been loaded.
-
-This allows you to delay execution of the `onLoad` callback until all other modules have been loaded.
-
-This is useful for returning contens of a module that depends on other modules.
-
-##### Example: tracking and reporting unused exports
-
-```ts
-import { plugin } from "bun";
-
-plugin({
-  name: "track imports",
-  setup(build) {
-    const transpiler = new Bun.Transpiler();
-
-    let trackedImports: Record<string, number> = {};
-
-    // Each module that goes through this onLoad callback
-    // will record its imports in `trackedImports`
-    build.onLoad({ filter: /\.ts/ }, async ({ path }) => {
-      const contents = await Bun.file(path).arrayBuffer();
-
-      const imports = transpiler.scanImports(contents);
-
-      for (const i of imports) {
-        trackedImports[i.path] = (trackedImports[i.path] || 0) + 1;
-      }
-
-      return undefined;
-    });
-
-    build.onLoad({ filter: /stats\.json/ }, async ({ defer }) => {
-      // Wait for all files to be loaded, ensuring
-      // that every file goes through the above `onLoad()` function
-      // and their imports tracked
-      await defer();
-
-      // Emit JSON containing the stats of each import
-      return {
-        contents: `export default ${JSON.stringify(trackedImports)}`,
-        loader: "json",
-      };
-    });
-  },
-});
-```
-
-Note that the `.defer()` function currently has the limitation that it can only be called once per `onLoad` callback.

+This is a proof of concept for using a third-party native addon in `Bun.build()`.
+
+This uses `mdxjs-rs` to convert MDX to JSX.
+
+TODO: **This needs to be built & published to npm.**
+
+## Building locally:
+
+```sh
+cargo build --release
+```
+
+```js
+import { build } from "bun";
+import mdx from "./index.js";
+
+// TODO: This needs to be prebuilt for the current platform
+// Probably use a napi-rs template for this
+import addon from "./target/release/libmdx_bun.dylib" with { type: "file" };
+
+const results = await build({
+  entrypoints: ["./hello.jsx"],
+  plugins: [mdx({ addon })],
+  minify: true,
+  outdir: "./dist",
+  define: {
+    "process.env.NODE_ENV": JSON.stringify("production"),
+  },
+});
