+`Worker` support was added in Bun v0.7.0.
+{% /callout %}
+
+[`Worker`](https://developer.mozilla.org/en-US/docs/Web/API/Worker) lets you start and communicate with a new JavaScript instance running on a separate thread while sharing I/O resources with the main thread.
+
+Bun implements a minimal version of the [Web Workers API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API) with extensions that make it work better for server-side use cases. Like the rest of Bun, `Worker` in Bun support CommonJS, ES Modules, TypeScript, JSX, TSX and more out of the box. No extra build steps are necessary.
+
+## Creating a `Worker`
+
+Like in browsers, [`Worker`](https://developer.mozilla.org/en-US/docs/Web/API/Worker) is a global. Use it to create a new worker thread.
+
+From the main thread:
+
+```js#Main_thread
+const workerURL = new URL("worker.ts", import.meta.url).href;
+const worker = new Worker(workerURL);
+
+worker.postMessage("hello");
+worker.onmessage = event => {
+  console.log(event.data);
+};
+```
+
+Worker thread:
+
+```ts#worker.ts_(Worker_thread)
+self.onmessage = (event: MessageEvent) => {
+  console.log(event.data);
+  postMessage("world");
+};
+```
+
+You can use `import`/`export` syntax in your worker code. Unlike in browsers, there's no need to specify `{type: "module"}` to use ES Modules.
+
+To simplify error handling, the initial script to load is resolved at the time `new Worker(url)` is called.
+
+```js
+const worker = new Worker("/not-found.js");
+// throws an error immediately
+```
+
+The specifier passed to `Worker` is resolved relative to the project root (like typing `bun ./path/to/file.js`).
+
+### `"open"`
+
+The `"open"` event is emitted when a worker is created and ready to receive messages. This can be used to send an initial message to a worker once it's ready. (This event does not exist in browsers.)
+
+```ts
+const worker = new Worker(new URL("worker.ts", import.meta.url).href);
+
+worker.addEventListener("open", () => {
+  console.log("worker is ready");
+});
+```
+
+Messages are automatically enqueued until the worker is ready, so there is no need to wait for the `"open"` event to send messages.
+
+## Messages with `postMessage`
+
+To send messages, use [`worker.postMessage`](https://developer.mozilla.org/en-US/docs/Web/API/Worker/postMessage) and [`self.postMessage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage). This leverages the [HTML Structured Clone Algorithm](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm).
+
+```js
+// On the worker thread, `postMessage` is automatically "routed" to the parent thread.
+postMessage({ hello: "world" });
+
+// On the main thread
+worker.postMessage({ hello: "world" });
+```
+
+To receive messages, use the [`message` event handler](https://developer.mozilla.org/en-US/docs/Web/API/Worker/message_event) on the worker and main thread.
+
+```js
+// Worker thread:
+self.addEventListener("message", event => {
+  console.log(event.data);
+});
+// or use the setter:
+// self.onmessage = fn
+
+// if on the main thread
+worker.addEventListener("message", event => {
+  console.log(event.data);
+});
+// or use the setter:
+// worker.onmessage = fn
+```
+
+## Terminating a worker
+
+A `Worker` instance terminate automatically when Bun's process exits. To terminate a `Worker` sooner, call `worker.terminate()`.
+
+```ts
+const worker = new Worker(new URL("worker.ts", import.meta.url).href);
+
+// ...some time later
+worker.terminate();
+```
+
+### `process.exit()`
+
+A worker can terminate itself with `process.exit()`. This does not terminate the main process. Like in Node.js, `process.on('beforeExit', callback)` and `process.on('exit', callback)` are emitted on the worker thread (and not on the main thread).
+
+### `"close"`
+
+The `"close"` event is emitted when a worker has been terminated. It can take some time for the worker to actually terminate, so this event is emitted when the worker has been marked as terminated.
+
+```ts
+const worker = new Worker(new URL("worker.ts", import.meta.url).href);
+
+worker.addEventListener("close", () => {
+  console.log("worker is being closed");
+});
+```
+
+This event does not exist in browsers.
+
+## Managing lifetime
+
+By default, an active `Worker` will _not_ keep the main (spawning) process alive. Once the main script finishes, the main thread will terminate, shutting down any workers it created.
+
+### `worker.ref`
+
+To keep the process alive until the `Worker` terminates, call `worker.ref()`. This couples the lifetime of the worker to the lifetime of the main process.
+
+```ts
+const worker = new Worker(new URL("worker.ts", import.meta.url).href);
+worker.ref();
+```
+
+Alternatively, you can also pass an `options` object to `Worker`:
+
+```ts
+const worker = new Worker(new URL("worker.ts", import.meta.url).href, {
+  ref: true,
+});
+```
+
+### `worker.unref`
+
+To stop keeping the process alive, call `worker.unref()`.
+
+```ts
+const worker = new Worker(new URL("worker.ts", import.meta.url).href);
+worker.ref();
+// ...later on
+worker.unref();
+```
+
+Note: `worker.ref()` and `worker.unref()` do not exist in browsers.
+
+## Memory usage with `smol`
+
+JavaScript instances can use a lot of memory. Bun's `Worker` supports a `smol` mode that reduces memory usage, at a cost of performance. To enable `smol` mode, pass `smol: true` to the `options` object in the `Worker` constructor.
+
+```js
+const worker = new Worker("./i-am-smol.ts", {
+  smol: true,
+});
+```
+
+{% details summary="What does `smol` mode actually do?" %}
+Setting `smol: true` sets `JSC::HeapSize` to be `Small` instead of the default `Large`.

+name: Convert a Uint8Array to an ArrayBuffer
+---
+
+A [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) is a _typed array_ class, meaning it is a mechanism for viewing data in an underlying `ArrayBuffer`. The underlying `ArrayBuffer` is accessible via the `buffer` property.
+
+```ts
+const arr = new Uint8Array(64);
+arr.buffer; // => ArrayBuffer(64)
+```
+
+---
+
+The `Uint8Array` may be a view over a _subset_ of the data in the underlying `ArrayBuffer`. In this case, the `buffer` property will return the entire buffer, and the `byteOffset` and `byteLength` properties will indicate the subset.
+
+```ts
+const arr = new Uint8Array(64, 16, 32);
+arr.buffer; // => ArrayBuffer(64)
+arr.byteOffset; // => 16
+arr.byteLength; // => 32

+Discord.js works [out of the box](https://bun.sh/blog/bun-v0.6.7) with Bun. Let's write a simple bot. First create a directory and initialize it with `bun init`.
+
+```bash
+mkdir my-bot
+cd my-bot
+bun init
+```
+
+---
+
+Now install Discord.js.
+
+```bash
+bun add discord.js
+```
+
+---
+
+Before we go further, we need to go to the [Discord developer portal](https://discord.com/developers/applications), login/signup, create a new _Application_, then create a new _Bot_ within that application. Follow the [official guide](https://discordjs.guide/preparations/setting-up-a-bot-application.html#creating-your-bot) for step-by-step instructions.
+
+---
+
+Once complete, you'll be presented with your bot's _private key_. Let's add this to a file called `.env.local`. Bun automatically reads this file and loads it into `process.env`.
+
+{% callout %}
+This is an example token that has already been invalidated.
+{% /callout %}
+
+```txt#.env.local
+DISCORD_TOKEN=NzkyNzE1NDU0MTk2MDg4ODQy.X-hvzA.Ovy4MCQywSkoMRRclStW4xAYK7I
+```
+
+---
+
+Be sure to add `.env.local` to your `.gitignore`! It is dangerous to check your bot's private key into version control.
+
+```txt#.gitignore
+node_modules
+.env.local
+```
+
+---
+
+Now let's actually write our bot in a new file called `bot.ts`.
+
+```ts#bot.ts
+// import discord.js
+import {Client, Events, GatewayIntentBits} from 'discord.js';
+
+// create a new Client instance
+const client = new Client({intents: [GatewayIntentBits.Guilds]});
+
+// listen for the client to be ready
+client.once(Events.ClientReady, (c) => {
+  console.log(`Ready! Logged in as ${c.user.tag}`);
+});
+
+// login with the token from .env.local
+client.login(process.env.DISCORD_TOKEN);
+```
+
+---
+
+Now we can run our bot with `bun run`. It may take a several seconds for the client to initialize the first time you run the file.
+
+```bash
+$ bun run bot.ts
+Ready! Logged in as my-bot#1234
+```
+
+---
+
+You're up and running with a bare-bones Discord.js bot! This is a basic guide to setting up your bot with Bun; we recommend the [official Discord docs](https://discordjs.guide/) for complete information on the `discord.js` API.

++   id    Int     @id @default(autoincrement())
++   email String  @unique
++   name  String?
++ }
+```
+
+---
+
+Then generate and run initial migration.
+
+This will generate a `.sql` migration file in `prisma/migrations`, create a new SQLite instance, and execute the migration against the new instance.
+
+```bash
+bunx prisma migrate dev --name init
+```
+
+---
+
+Prisma automatically generates our _Prisma client_ whenever we execute a new migration. The client provides a fully typed API for reading and writing from our database.
+
+It can be imported from `@prisma/client`.
+
+```ts#src/index.ts
+import {PrismaClient} from "@prisma/client";
+```
+
+---
+
+Let's write a simple script to create a new user, then count the number of users in the database.

+const prisma = new PrismaClient();
+
+// create a new user

+  },
+});
+
+// count the number of users
+const count = await prisma.user.count();
+console.log(`There are ${count} users in the database.`);
+```
+
+---
+
+Let's run this script with `bun run`. Each time we run it, a new user is created.
+
+```bash
+$ bun run index.ts
+Created john-0.12802932895402364@example.com
+There are 1 users in the database.
+$ bun run index.ts

+
+```sh
+bun --hot run index.ts

+
+For CLI tools, it's often useful to read from `stdin`. In Bun, the `console` object is an `AsyncIterable` that yields lines from `stdin`.
+
+```ts#index.ts
+const prompt = "Type something: ";
+process.stdout.write(prompt);

+  console.log(`You typed: ${line}`);
+  process.stdout.write(prompt);

+```sh
+$ bun run index.tsx
+Type something: hello
+You typed: hello
+Type something: hello again
+You typed: hello again
+```
+
+---
+
+Bun also exposes stdin as a `BunFile` via `Bun.stdin`. This is useful for incrementally reading large inputs that are piped into the `bun` process.
+
+There is no guarantee that the chunks will be split line-by-line.
+
+```ts#stdin.ts
+for await (const chunk of Bun.stdin.stream()) {
+  // chunk is Uint8Array
+  // this converts it to text (assumes ASCII encoding)
+  const chunkText = Buffer.from(chunk).toString();
+  console.log(`Chunk: ${chunkText}`);

+name: Watch a directory for changes
+---
+
+Bun implements the `node:fs` module, including the `fs.watch` function for listening for file system changes.
+
+This code block listens for changes to files in the current directory. By default this operation is _shallow_, meaning that changes to files in subdirectories will not be detected.
+
+```ts
+import { watch } from "fs";
+
+const watcher = watch(import.meta.dir, (event, filename) => {
+  console.log(`Detected ${event} in ${filename}`);
+});
+```
+
+---
+
+To listen to changes in subdirectories, pass the `recursive: true` option to `fs.watch`.
+
+```ts
+import { watch } from "fs";
+
+const watcher = watch(
+  import.meta.dir,
+  { recursive: true },
+  (event, filename) => {
+    console.log(`Detected ${event} in ${filename}`);
+  },
+);
+```
+
+---
+
+Using the `node:fs/promises` module, you can listen for changes using `for await...of` instead of a callback.
+
+```ts
+import { watch } from "fs/promises";
+
+const watcher = watch(import.meta.dir);
+for await (const event of watcher) {
+  console.log(`Detected ${event.eventType} in ${event.filename}`);
+}
+```
+
+---
+
+To stop listening for changes, call `watcher.close()`. It's common to do this when the process receives a `SIGINT` signal, such as when the user presses Ctrl-C.
+
+```ts
+import { watch } from "fs";
+
+const watcher = watch(import.meta.dir, (event, filename) => {
+  console.log(`Detected ${event} in ${filename}`);
+});
+
+process.on("SIGINT", () => {
+  // close watcher when Ctrl-C is pressed

+  watcher.close();
