+## Inter-process communication (IPC)
+
+Bun supports direct inter-process communication channel between two `bun` processes. To receive messages from a spawned Bun subprocess, specify an `ipc` handler.
+{%callout%}
+**Note** — This API is only compatible with other `bun` processes. Use `process.execPath` to get a path to the currently running `bun` executable.
+{%/callout%}
+
+```ts#parent.ts
+const child = Bun.spawn(["bun", "child.ts"], {
+  ipc(message) {
+    /**
+     * The message received from the sub process
+     **/
+  },
+});
+```
+
+The parent process can send messages to the subprocess using the `.send()` method on the returned `Subprocess` instance. A reference to the sending subprocess is also available as the second argument in the `ipc` handler.
+
+```ts#parent.ts
+const childProc = Bun.spawn(["bun", "child.ts"], {
+  ipc(message, childProc) {
+    /**
+     * The message received from the sub process
+     **/
+    childProc.send("Respond to child")
+  },
+});
+
+childProc.send("I am your father"); // The parent can send messages to the child as well
+```
+
+Meanwhile the child process can send messages to its parent using with `process.send()` and receive messages with `process.on("message")`. This is the same API used for `child_process.fork()` in Node.js.
+
+```ts#child.ts
+process.send("Hello from child as string");
+process.send({ message: "Hello from child as object" });
+
+process.on("message", (message) => {
+  // print message from parent
+  console.log(message);
+});
+```
+
+All messages are serialized using the JSC `serialize` API, which allows for the same set of [transferrable types](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Transferable_objects) supported by `postMessage` and `structuredClone`, including strings, typed arrays, streams, and objects.
+
+```ts#child.ts
+// send a string
+process.send("Hello from child as string");
+
+// send an object
+process.send({ message: "Hello from child as object" });
+```
+
 ## Blocking API (`Bun.spawnSync()`)
 
 Bun provides a synchronous equivalent of `Bun.spawn` called `Bun.spawnSync`. This is a blocking API that supports the same inputs and parameters as `Bun.spawn`. It returns a `SyncSubprocess` object, which differs from `Subprocess` in a few ways.

+## Trusted dependencies
+

+
+To tell Bun to allow lifecycle scripts for a particular package, add the package to `trustedDependencies` in your package.json.

+    "name": "my-app",
+    "version": "1.0.0",

+## Git dependencies
+
+To add a dependency from a git repository:
+
+```bash
+$ bun add git@github.com:moment/moment.git
+```
+
+Bun supports a variety of protocols, including [`github`](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#github-urls), [`git`](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#git-urls-as-dependencies), `git+ssh`, `git+https`, and many more.

+## Tarball dependencies

-When you run `bun create ${template} ${destination}`, here’s what happens:
-
-IF remote template
-
-1. GET `registry.npmjs.org/@bun-examples/${template}/latest` and parse it
-2. GET `registry.npmjs.org/@bun-examples/${template}/-/${template}-${latestVersion}.tgz`
-3. Decompress & extract `${template}-${latestVersion}.tgz` into `${destination}`
-
-   - If there are files that would overwrite, warn and exit unless `--force` is passed
-
-IF GitHub repo
-
-1. Download the tarball from GitHub’s API
-2. Decompress & extract into `${destination}`
-
-   - If there are files that would overwrite, warn and exit unless `--force` is passed
-
-ELSE IF local template
-
-1. Open local template folder
-2. Delete destination directory recursively
-3. Copy files recursively using the fastest system calls available (on macOS `fcopyfile` and Linux, `copy_file_range`). Do not copy or traverse into `node_modules` folder if exists (this alone makes it faster than `cp`)
-
-4. Parse the `package.json` (again!), update `name` to be `${basename(destination)}`, remove the `bun-create` section from the `package.json` and save the updated `package.json` to disk.
-   - IF Next.js is detected, add `bun-framework-next` to the list of dependencies
-   - IF Create React App is detected, add the entry point in /src/index.{js,jsx,ts,tsx} to `public/index.html`
-   - IF Relay is detected, add `bun-macro-relay` so that Relay works
-5. Auto-detect the npm client, preferring `pnpm`, `yarn` (v1), and lastly `npm`
-6. Run any tasks defined in `"bun-create": { "preinstall" }` with the npm client
-7. Run `${npmClient} install` unless `--no-install` is passed OR no dependencies are in package.json
-8. Run any tasks defined in `"bun-create": { "preinstall" }` with the npm client
-9. Run `git init; git add -A .; git commit -am "Initial Commit";`
-
-   - Rename `gitignore` to `.gitignore`. NPM automatically removes `.gitignore` files from appearing in packages.
-   - If there are dependencies, this runs in a separate thread concurrently while node_modules are being installed
-   - Using libgit2 if available was tested and performed 3x slower in microbenchmarks

   }
 }
 ```
 
-To install a package globally:
+## Overrides and resolutions
+
+Bun supports npm's `"overrides"` and Yarn's `"resolutions"` in `package.json`. These are mechanisms for specifying a version range for _metadependencies_—the dependencies of your dependencies. Refer to [Package manager > Overrides and resolutions](/docs/install/overrides) for complete documentation.

-
-To use cool-pkg in a project, run:
-  bun link cool-pkg
-
-Or add it in dependencies in your package.json file:
-  "cool-pkg": "link:cool-pkg"
+$ bun install --dry-run
 ```
 
-This package can now be "linked" into other projects using `bun link cool-pkg`. This will create a symlink in the `node_modules` directory of the target project, pointing to the local directory.
+## Non-npm dependencies
 
-```bash
-$ cd /path/to/my-app
-$ bun link cool-pkg
-```
+Bun supports installing dependencies from Git, GitHub, and local or remotely-hosted tarballs. For complete documentation refer to [Package manager > Git, GitHub, and tarball dependencies](/docs/cli/add).
 
-In addition, the `--save` flag can be used to add `cool-pkg` to the `dependencies` field of your app's package.json with a special version specifier that tells Bun to load from the registered local directory instead of installing from `npm`:
-
-```json-diff
-  {
-    "name": "my-app",
-    "version": "1.0.0",
-    "dependencies": {
-+     "cool-pkg": "link:cool-pkg"
-    }
-  }
-```
-
-## Trusted dependencies
-
-Unlike other npm clients, Bun does not execute arbitrary lifecycle scripts for installed dependencies, such as `postinstall`. These scripts represent a potential security risk, as they can execute arbitrary code on your machine.
-
-<!-- Bun maintains an allow-list of popular packages containing `postinstall` scripts that are known to be safe. To run lifecycle scripts for packages that aren't on this list, add the package to `trustedDependencies` in your package.json. -->
-
-To tell Bun to allow lifecycle scripts for a particular package, add the package to `trustedDependencies` in your package.json.
-
-<!-- ```json-diff
-  {
-    "name": "my-app",
-    "version": "1.0.0",
-+   "trustedDependencies": {
-+     "my-trusted-package": "*"
-+   }
-  }
-``` -->
-
-```json-diff
-  {
-    "name": "my-app",
-    "version": "1.0.0",
-+   "trustedDependencies": ["my-trusted-package"]
-  }
-```
-
-Bun reads this field and will run lifecycle scripts for `my-trusted-package`.
-
-<!-- If you specify a version range, Bun will only execute lifecycle scripts if the resolved package version matches the range. -->
-<!--
-```json
-{
-  "name": "my-app",
-  "version": "1.0.0",
-  "trustedDependencies": {
-    "my-trusted-package": "^1.0.0"
-  }
-}
-``` -->
-
-## Git dependencies
-
-To add a dependency from a git repository:
-
-```bash
-$ bun install git@github.com:moment/moment.git
-```
-
-Bun supports a variety of protocols, including [`github`](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#github-urls), [`git`](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#git-urls-as-dependencies), `git+ssh`, `git+https`, and many more.
-
-```json
+```json#package.json

-## Tarball dependencies
+## Configuration
 
-A package name can correspond to a publicly hosted `.tgz` file. During `bun install`, Bun will download and install the package from the specified tarball URL, rather than from the package registry.
+The default behavior of `bun install` can be configured in `bunfig.toml`. The default values are shown below.
 
-```json#package.json

+name: Containerize a Bun application with Docker
+---
+
+{% callout %}
+This guide assumes you already have [Docker Desktop](https://www.docker.com/products/docker-desktop/) installed.
+{% /callout %}
+
+[Docker](https://www.docker.com) is a platform for packaging and running an application as a lightweight, portable _container_ that encapsulates all the necessary dependencies.
+
+---
+
+To _containerize_ our application, we define a `Dockerfile`. This file contains a list of instructions to initialize the container, copy our local project files into it, install dependencies, and starts the application.
+
+```docker#Dockerfile
+# use the official Bun image
+# see all versions at https://hub.docker.com/r/oven/bun/tags
+FROM oven/bun:1 as base
+WORKDIR /usr/src/app
+
+# install dependencies into temp directory
+# this will cache them and speed up future builds
+FROM base AS install
+RUN mkdir -p /temp/dev
+COPY package.json bun.lockb /temp/dev/
+RUN cd /temp/dev && bun install --frozen-lockfile
+
+# install with --production (exclude devDependencies)
+RUN mkdir -p /temp/prod
+COPY package.json bun.lockb /temp/prod/
+RUN cd /temp/prod && bun install --frozen-lockfile --production
+
+# copy node_modules from temp directory
+# then copy all (non-ignored) project files into the image
+FROM install AS prerelease
+COPY --from=install /temp/dev/node_modules node_modules
+COPY . .
+
+# [optional] tests & build
+ENV NODE_ENV=production
+RUN bun test
+RUN bun run build
+
+# copy production dependencies and source code into final image
+FROM base AS release
+COPY --from=install /temp/prod/node_modules node_modules
+COPY --from=prerelease /usr/src/app/index.ts .
+COPY --from=prerelease /usr/src/app/package.json .
+
+# run the app
+USER bun
+EXPOSE 3000/tcp
+ENTRYPOINT [ "bun", "run", "index.ts" ]
+```
+
+---
+
+Now that you have your docker image, let's look at `.dockerignore` which has the same syntax as `.gitignore`, here you need to specify the files/directories that must not go in any stage of the docker build. An example for a ignore file is
+
+```txt#.dockerignore
+node_modules
+Dockerfile*
+docker-compose*
+.dockerignore
+.git
+.gitignore
+README.md
+LICENSE
+.vscode
+Makefile
+helm-charts
+.env
+.editorconfig
+.idea
+coverage*
+```
+
+---
+
+We'll now use `docker build` to convert this `Dockerfile` into a _Docker image_, is a self-contained template containing all the dependencies and configuration required to run the application.
+
+The `-t` flag lets us specify a name for the image, and `--pull` tells Docker to automatically download the latest version of the base image (`oven/bun`). The initial build will take longer, as Docker will download all the base images and dependencies.

+
+The `run` command prints a string representing the _container ID_.
+
+```sh
+$ docker run -d -p 3000:3000 bun-hello-world

+
+---
+
+The container is now running in the background. Visit [localhost:3000](http://localhost:3000). You should see a `Hello, World!` message.
+
+---
+
+To stop the container, we'll use `docker stop <container-id>`.
+
+```sh
+$ docker stop 7f03e212a15ede8644379bce11a13589f563d3909a9640446c5bbefce993678d

+
+---
+
+If you can't find the container ID, you can use `docker ps` to list all running containers.

+```sh

+[PM2](https://pm2.keymetrics.io/) is a popular process manager that manages and runs your applications as daemons (background processes).
+
+It offers features like process monitoring, automatic restarts, and easy scaling. Using a process manager is common when deploying a Bun application on a cloud-hosted virtual private server (VPS), as it:
+
+- Keeps your Node.js application running continuously.
+- Ensure high availability and reliability of your application.
+- Monitor and manage multiple processes with ease.
+- Simplify the deployment process.
+

+
+You can use PM2 with Bun in two ways: as a CLI option or in a configuration file.
+
+### With `--interpreter`
+
+---
+
+To start your application with PM2 and Bun as the interpreter, open your terminal and run the following command:
+
+```bash
+pm2 start --interpreter ~/.bun/bin/bun index.ts
+```
+
+---
+
+### With a configuration file
+
+---
+
+Alternatively, you can create a PM2 configuration file. Create a file named `pm2.config.js` in your project directory and add the following content.
+
+```javascript
+module.exports = {
+  name: "app", // Name of your application
+  script: "index.ts", // Entry point of your application

+
+Use [`Bun.spawn()`](/docs/api/spawn) to spawn a child process. When spawning a second `bun` process, you can open a direct inter-process communication (IPC) channel between the two processes.
+
+{%callout%}
+**Note** — This API is only compatible with other `bun` processes. Use `process.execPath` to get a path to the currently running `bun` executable.

+  ipc(message) {
+    /**
+     * The message received from the sub process
+     **/
+  },
+});
+```
+
+---
+
+The parent process can send messages to the subprocess using the `.send()` method on the returned `Subprocess` instance. A reference to the sending subprocess is also available as the second argument in the `ipc` handler.
+
+```ts#parent.ts
+const childProc = Bun.spawn(["bun", "child.ts"], {
+  ipc(message, childProc) {
+    /**
+     * The message received from the sub process
+     **/
+    childProc.send("Respond to child")
+  },
+});
+
+childProc.send("I am your father"); // The parent can send messages to the child as well
+```
+
+---
+
+Meanwhile the child process can send messages to its parent using with `process.send()` and receive messages with `process.on("message")`. This is the same API used for `child_process.fork()` in Node.js.
+
+```ts#child.ts
+process.send("Hello from child as string");
+process.send({ message: "Hello from child as object" });
+
+process.on("message", (message) => {
+  // print message from parent
+  console.log(message);
+});
+```
+

+
+All messages are serialized using the JSC `serialize` API, which allows for the same set of [transferrable types](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Transferable_objects) supported by `postMessage` and `structuredClone`, including strings, typed arrays, streams, and objects.

+Packages on `npm` can define _lifecycle scripts_ in their `package.json`. Some of the most common are below, but there are [many others](https://docs.npmjs.com/cli/v10/using-npm/scripts).
+
+- `preinstall`: Runs before the package is installed
+- `postinstall`: Runs after the package is installed
+- `preuninstall`: Runs before the package is uninstalled
+- `prepublishOnly`: Runs before the package is published
+
+These scripts are arbitrary shell commands that the package manager is expected to read and execute at the appropriate time. But executing arbitrary scripts represents a potential security risk, so—unlike other `npm` clients—Bun does not execute arbitrary lifecycle scripts by default.
+
+## `postinstall`
+
+The `postinstall` script is particularly important. It's widely used to build or install platform-specific binaries for packages that are implemented as [native Node.js add-ons](https://nodejs.org/api/addons.html). For example, `node-sass` is a popular package that uses `postinstall` to build a native binary for Sass.
+
+```json
+{
+  "name": "my-app",
+  "version": "1.0.0",
+  "dependencies": {
+    "node-sass": "^6.0.1"
+  }
+}
+```
+
+## `trustedDependencies`
+
+Instead of executing arbitrary scripts, Bun uses a "default-secure" approach. You can add certain packages to an allow list, and Bun will execute lifecycle scripts for those packages. To tell Bun to allow lifecycle scripts for a particular package, add the package name to `trustedDependencies` array in your `package.json`.
+
+```json-diff
+  {
+    "name": "my-app",
+    "version": "1.0.0",
++   "trustedDependencies": ["node-sass"]
+  }
+```
+
+Once added to `trustedDependencies`, install/re-install the package. Bun will read this field and run lifecycle scripts for `my-trusted-package`.
+
+## `--ignore-scripts`
+
+To disable lifecycle scripts for all packages, use the `--ignore-scripts` flag.
+
+```bash
+$ bun install --ignore-scripts
+```

+Bun supports npm's `"overrides"` and Yarn's `"resolutions"` in `package.json`. These are mechanisms for specifying a version range for _metadependencies_—the dependencies of your dependencies. Refer to [Package manager > Overrides and resolutions](/docs/install/overrides) for complete documentation.
+
+```json-diff#package.json

+    },
++   "overrides": {
++     "bar": "~4.4.0"
++   }
+  }
+```
+
+By default, Bun will install the latest version of all dependencies and metadependencies, according to the ranges specified in each package's `package.json`. Let's say you have a project with one dependency, `foo`, which in turn has a dependency on `bar`. This means `bar` is a _metadependency_ of our project.
+
+```json#package.json
+{
+  "name": "my-app",
+  "dependencies": {

+node_modules
+├── foo@1.2.3
+└── bar@4.5.6
+```
+
+But what if a security vulnerability was introduced in `bar@4.5.6`? We may want a way to pin `bar` to an older version that doesn't have the vulerability. This is where `"overrides"`/`"resolutions"` come in.
+
+## `"overrides"`
+
+Add `bar` to the `"overrides"` field in `package.json`. Bun will defer to the specified version range when determining which version of `bar` to install, whether it's a dependency or a metadependency.
+
+{% callout %}
+**Note** — Bun currently only supports top-level `"overrides"`. [Nested overrides](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#overrides) are not supported.

-# Upcoming release
-
-- [Bun.js] Enable `SharedArrayBuffer` and Atomics
-
-# 0.41.0
-
-- [bun run] `bun run ./file.js` now supports running JavaScript, TS, TSX, and JSX files with Bun.js. Before, it would say `"error: Missing script"`. If there is a `#!` shebang at the start of the file, the file will not be run with Bun.js. You can still use Node & Deno with `bun run`, that works the same as before.
-- [Bun.js] Top-level await
-- [Bun.js] `performance.now()` is implemented
-- [Bun.js] `fetch()` is fixed
-- [.env loader] Pass through process environment variable values verbatim instead of treating them similarly to .env files. `.env` needs special parsing because quotes are optional, values are potentially nested, and it's whitespace sensitive. This probably also improves the performance of loading process environment variables, but that was already pretty quick so it probably doesn't matter.
