+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 Also, according to this [issue](https://github.com/llvm/llvm-project/issues/97314), LLVM 16 is no longer maintained on Ubuntu 24.04 (noble).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.

+Bun implements the WHATWG `fetch` standard, with some extensions to meet the needs of server-side JavaScript.
+
+Bun also implements `node:http`, but `fetch` is generally recommended instead.
+
+## Sending an HTTP request
+
+To send an HTTP request, use `fetch`
+
+```ts
+const response = await fetch("http://example.com");
+
+console.log(response.status); // => 200
+
+const text = await response.text(); // or response.json(), response.formData(), etc.
+```
+
+`fetch` also works with HTTPS URLs.
+
+```ts
+const response = await fetch("https://example.com");
+```
+
+You can also pass `fetch` a [`Request`](https://developer.mozilla.org/en-US/docs/Web/API/Request) object.
+
+```ts
+const request = new Request("http://example.com", {
+  method: "POST",
+  body: "Hello, world!",
+});
+
+const response = await fetch(request);
+```
+
+### Sending a POST request
+
+To send a POST request, pass an object with the `method` property set to `"POST"`.
+
+```ts
+const response = await fetch("http://example.com", {
+  method: "POST",
+  body: "Hello, world!",
+});
+```
+
+`body` can be a string, a `FormData` object, an `ArrayBuffer`, a `Blob`, and more. See the [MDN documentation](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch#setting_a_body) for more information.
+
+### Proxying requests
+
+To proxy a request, pass an object with the `proxy` property set to a URL.
+
+```ts
+const response = await fetch("http://example.com", {
+  proxy: "http://proxy.com",
+});
+```
+
+### Custom headers
+
+To set custom headers, pass an object with the `headers` property set to an object.
+
+```ts
+const response = await fetch("http://example.com", {
+  headers: {
+    "X-Custom-Header": "value",
+  },
+});
+```
+
+You can also set headers using the [Headers](https://developer.mozilla.org/en-US/docs/Web/API/Headers) object.
+
+```ts
+const headers = new Headers();
+headers.append("X-Custom-Header", "value");
+
+const response = await fetch("http://example.com", {
+  headers,
+});
+```
+
+### Response bodies
+
+To read the response body, use one of the following methods:
+
+- `response.text(): Promise<string>`: Returns a promise that resolves with the response body as a string.
+- `response.json(): Promise<any>`: Returns a promise that resolves with the response body as a JSON object.
+- `response.formData(): Promise<FormData>`: Returns a promise that resolves with the response body as a `FormData` object.
+- `response.bytes(): Promise<Uint8Array>`: Returns a promise that resolves with the response body as a `Uint8Array`.
+- `response.arrayBuffer(): Promise<ArrayBuffer>`: Returns a promise that resolves with the response body as an `ArrayBuffer`.
+- `response.blob(): Promise<Blob>`: Returns a promise that resolves with the response body as a `Blob`.
+
+#### Streaming response bodies
+
+You can use async iterators to stream the response body.
+
+```ts
+const response = await fetch("http://example.com");
+
+for await (const chunk of response.body) {
+  console.log(chunk);
+}
+```
+
+You can also more directly access the `ReadableStream` object.
+
+```ts
+const response = await fetch("http://example.com");
+
+const stream = response.body;
+
+const reader = stream.getReader();
+const { value, done } = await reader.read();
+```
+
+### Fetching a URL with a timeout
+
+To fetch a URL with a timeout, use `AbortSignal.timeout`:
+
+```ts
+const response = await fetch("http://example.com", {
+  signal: AbortSignal.timeout(1000),
+});
+```
+
+#### Canceling a request
+
+To cancel a request, use an `AbortController`:
+
+```ts
+const controller = new AbortController();
+
+const response = await fetch("http://example.com", {
+  signal: controller.signal,
+});
+
+controller.abort();
+```
+
+### Unix domain sockets
+
+To fetch a URL using a Unix domain socket, use the `unix: string` option:
+
+```ts
+const response = await fetch("https://hostname/a/path", {
+  unix: "/var/run/path/to/unix.sock",
+  method: "POST",
+  body: JSON.stringify({ message: "Hello from Bun!" }),
+  headers: {
+    "Content-Type": "application/json",
+  },
+});
+```
+
+### TLS
+
+To use a client certificate, use the `tls` option:
+
+```ts
+await fetch("https://example.com", {
+  tls: {
+    key: Bun.file("/path/to/key.pem"),
+    cert: Bun.file("/path/to/cert.pem"),
+    // ca: [Bun.file("/path/to/ca.pem")],
+  },
+});
+```
+
+#### Custom TLS Validation
+
+To customize the TLS validation, use the `checkServerIdentity` option in `tls`
+
+```ts
+await fetch("https://example.com", {
+  tls: {
+    checkServerIdentity: (hostname, peerCertificate) => {
+      // Return an error if the certificate is invalid
+    },
+  },
+});
+```
+
+This is similar to how it works in Node's `net` module.
+
+## Debugging
+
+To help with debugging, you can pass `verbose: true` to `fetch`:
+
+```ts
+const response = await fetch("http://example.com", {
+  verbose: true,
+});
+```
+
+This will print the request and response headers to your terminal:
+
+```sh
+[fetch] > HTTP/1.1 GET http://example.com/
+[fetch] > Connection: keep-alive
+[fetch] > User-Agent: Bun/1.1.21
+[fetch] > Accept: */*
+[fetch] > Host: example.com
+[fetch] > Accept-Encoding: gzip, deflate, br
+
+[fetch] < 200 OK
+[fetch] < Content-Encoding: gzip
+[fetch] < Age: 201555
+[fetch] < Cache-Control: max-age=604800
+[fetch] < Content-Type: text/html; charset=UTF-8
+[fetch] < Date: Sun, 21 Jul 2024 02:41:14 GMT
+[fetch] < Etag: "3147526947+gzip"
+[fetch] < Expires: Sun, 28 Jul 2024 02:41:14 GMT
+[fetch] < Last-Modified: Thu, 17 Oct 2019 07:18:26 GMT
+[fetch] < Server: ECAcc (sac/254F)
+[fetch] < Vary: Accept-Encoding
+[fetch] < X-Cache: HIT
+[fetch] < Content-Length: 648
+```
+
+Note: `verbose: boolean` is not part of the Web standard `fetch` API and is specific to Bun.
+
+## Performance
+
+Before an HTTP request can be sent, the DNS lookup must be performed. This can take a significant amount of time, especially if the DNS server is slow or the network connection is poor.
+
+After the DNS lookup, the TCP socket must be connected and the TLS handshake might need to be performed. This can also take a significant amount of time.
+
+After the request completes, consuming the response body can also take a significant amount of time and memory.
+
+At every step of the way, Bun provides APIs to help you optimize the performance of your application.
+
+### DNS prefetching
+
+To prefetch a DNS entry, you can use the `dns.prefetch` API. This API is useful when you know you'll need to connect to a host soon and want to avoid the initial DNS lookup.
+
+```ts
+import { dns } from "bun";
+
+dns.prefetch("bun.sh", 443);
+```
+
+#### DNS caching
+
+By default, Bun caches and deduplicates DNS queries in-memory for up to 30 seconds. You can see the cache stats by calling `dns.getCacheStats()`:
+
+To learn more about DNS caching in Bun, see the [DNS caching](/docs/api/dns) documentation.
+
+### Preconnect to a host
+
+To preconnect to a host, you can use the `fetch.preconnect` API. This API is useful when you know you'll need to connect to a host soon and want to start the initial DNS lookup, TCP socket connection, and TLS handshake early.
+
+```ts
+import { fetch } from "bun";
+
+fetch.preconnect("https://bun.sh");
+```
+
+Note: calling `fetch` immediately after `fetch.preconnect` will not make your request faster. Preconnecting only helps if you know you'll need to connect to a host soon, but you're not ready to make the request yet.
+
+#### Preconnect at startup
+
+To preconnect to a host at startup, you can pass `--fetch-preconnect`:
+
+```sh
+$ bun --fetch-preconnect https://bun.sh ./my-script.ts
+```
+
+This is sort of like `<link rel="preconnect">` in HTML.
+
+This feature is not implemented on Windows yet. If you're interested in using this feature on Windows, please file an issue and we can implement support for it on Windows.
+
+### Connection pooling & HTTP keep-alive
+
+Bun automatically reuses connections to the same host. This is known as connection pooling. This can significantly reduce the time it takes to establish a connection. You don't need to do anything to enable this; it's automatic.
+
+#### Simultaneous connection limit
+
+By default, Bun limits the maximum number of simultaneous `fetch` requests to 256. We do this for several reasons:
+
+- It improves overall system stability. Operating systems have an upper limit on the number of simultaneous open TCP sockets, usually in the low thousands. Nearing this limit causes your entire computer to behave strangely. Applications hang and crash.
+- It encourages HTTP Keep-Alive connection reuse. For short-lived HTTP requests, the slowest step is often the initial connection setup. Reusing connections can save a lot of time.
+
+When the limit is exceeded, the requests are queued and sent as soon as the next request ends.
+
+You can increase the maximum number of simultaneous connections via the `BUN_CONFIG_MAX_HTTP_REQUESTS` environment variable:
+
+```sh
+$ BUN_CONFIG_MAX_HTTP_REQUESTS=512 bun ./my-script.ts
+```
+
+The max value for this limit is currently set to 65,336. The maximum port number is 65,535, so it's quite difficult for any one computer to exceed this limit.
+
+### Response buffering
+
+Bun goes to great lengths to optimize the performance of reading the response body. The fastest way to read the response body is to use one of these methods:
+
+- `response.text(): Promise<string>`
+- `response.json(): Promise<any>`
+- `response.formData(): Promise<FormData>`
+- `response.bytes(): Promise<Uint8Array>`
+- `response.arrayBuffer(): Promise<ArrayBuffer>`
+- `response.blob(): Promise<Blob>`
+
+You can also use `Bun.write` to write the response body to a file on disk:
+
+```ts
+import { write } from "bun";
+
+await write("output.txt", response);
+```

 The `--sourcemap` argument embeds a sourcemap compressed with zstd, so that errors & stacktraces point to their original locations instead of the transpiled location. Bun will automatically decompress & resolve the sourcemap when an error occurs.
 
+## Worker
+
+To use workers in a standalone executable, add the worker's entrypoint to the CLI arguments:
+
+```sh
+$ bun build --compile ./index.ts ./my-worker.ts --outfile myapp
+```
+
+Then, reference the worker in your code:
+
+```ts
+console.log("Hello from Bun!");
+
+// Any of these will work:
+new Worker("./my-worker.ts");
+new Worker(new URL("./my-worker.ts", import.meta.url));
+new Worker(new URL("./my-worker.ts", import.meta.url).href);
+```
+
+As of Bun v1.1.25, when you add multiple entrypoints to a standalone executable, they will be bundled separately into the executable.
+
+In the future, we may automatically detect usages of statically-known paths in `new Worker(path)` and then bundle those into the executable, but for now, you'll need to add it to the shell command manually like the above example.
+
+If you use a relative path to a file not included in the standalone executable, it will attempt to load that path from disk relative to the current working directory of the process (and then error if it doesn't exist).

 Unfortunately, if you're using `@mapbox/node-pre-gyp` or other similar tools, you'll need to make sure the `.node` file is directly required or it won't bundle correctly.
 
+### Embed directories
+
+To embed a directory with `bun build --compile`, use a shell glob in your `bun build` command:
+
+```sh
+$ bun build --compile ./index.ts ./public/**/*.png
+```
+
+Then, you can reference the files in your code:
+
+```ts
+import icon from "./public/assets/icon.png" with { type: "file" };
+import { file } from "bun";
+
+export default {
+  fetch(req) {
+    // Embedded files can be streamed from Response objects
+    return new Response(file(icon));
+  },
+};
+```
+
+This is honestly a workaround, and we expect to improve this in the future with a more direct API.
+
+### Listing embedded files
+
+To get a list of all embedded files, use `Bun.embeddedFiles`:
+
+```js
+import "./icon.png" with { type: "file" };
+import { embeddedFiles } from "bun";
+
+console.log(embeddedFiles[0].name); // `icon-${hash}.png`
+```
+
+`Bun.embeddedFiles` returns an array of `Blob` objects which you can use to get the size, contents, and other properties of the files.
+
+```ts
+embeddedFiles: Blob[]
+```
+
+The list of embedded files excludes bundled source code like `.ts` and `.js` files.
+
+#### Content hash
+
+By default, embedded files have a content hash appended to their name. This is useful for situations where you want to serve the file from a URL or CDN and have fewer cache invalidation issues. But sometimes, this is unexpected and you might want the original name instead:
+
+To disable the content hash, pass `--asset-naming` to `bun build --compile` like this:
+
+```sh
+$ bun build --compile --asset-naming="[name].[ext]" ./index.ts
+```
+
 ## Minification
 
 To trim down the size of the executable a little, pass `--minify` to `bun build --compile`. This uses Bun's minifier to reduce the code size. Overall though, Bun's binary is still way too big and we need to make it smaller.

docs/test/mocks.md

@@ -196,3 +196,41 @@ As of Bun v1.0.19, Bun automatically resolves the `specifier` argument to `mock.
 After resolution, the mocked module is stored in the ES Module registry **and** the CommonJS require cache. This means that you can use `import` and `require` interchangeably for mocked modules.
 
 The callback function is called lazily, only if the module is imported or required. This means that you can use `mock.module()` to mock modules that don't exist yet, and it means that you can use `mock.module()` to mock modules that are imported by other modules.
+
+## Restore all function mocks to their original values with `mock.restore()`
+
+Instead of manually restoring each mock individually with `mockFn.mockRestore()`, restore all mocks with one command by calling `mock.restore()`. Doing so does not reset the value of modules overridden with `mock.module()`.
+
+Using `mock.restore()` can reduce the amount of code in your tests by adding it to `afterEach` blocks in each test file or even in your [test preload code](https://bun.sh/docs/runtime/bunfig#test-preload).
+
+```ts
+import { expect, mock, spyOn, test } from "bun:test";
+
+import * as fooModule from './foo.ts';
+import * as barModule from './bar.ts';
+import * as bazModule from './baz.ts';
+
+test('foo, bar, baz', () => {
+  const fooSpy = spyOn(fooModule, 'foo');
+  const barSpy = spyOn(barModule, 'bar');
+  const bazSpy = spyOn(bazModule, 'baz');
