# bun create

> Create a new Bun project from a React component, a `create-<template>` npm package, a GitHub repo, or a local template

<Note>
  `bun create` is optional — Bun works without any configuration. This command exists to make getting started faster.
</Note>

***

Template a new Bun project with `bun create`. It creates a project from a React component, a `create-<template>` npm package, a GitHub repo, or a local template.

To create an empty project, use [`bun init`](/runtime/templating/init).

## From a React component

`bun create ./MyComponent.tsx` turns an existing React component into a complete dev environment with hot reload and production builds in one command.

```bash theme={"theme":{"light":"github-light","dark":"dracula"}}
bun create ./MyComponent.jsx # .tsx also supported
```

<Note>
  🚀 **Create React App Successor** — `bun create <component>` provides everything developers loved about Create React App, but with modern tooling, faster builds, and backend support.
</Note>

#### How this works

When you run `bun create <component>`, Bun:

1. Uses [Bun's JavaScript bundler](/bundler) to analyze your module graph.
2. Collects all the dependencies needed to run the component.
3. Scans the exports of the entry point for a React component.
4. Generates a `package.json` file with the dependencies and scripts needed to run the component.
5. Installs any missing dependencies using [`bun install --only-missing`](/pm/cli/install).
6. Generates the following files:
   * `${component}.html`
   * `${component}.client.tsx` (entry point for the frontend)
   * `${component}.css`
7. Starts a frontend dev server.

### Using TailwindCSS with Bun

[TailwindCSS](https://tailwindcss.com/) is a utility-first CSS framework for styling web applications.

When you run `bun create <component>`, Bun scans your JSX/TSX file for TailwindCSS class names (and any files it imports). If it detects TailwindCSS class names, it adds the following dependencies to your `package.json`:

```json package.json icon="file-json" theme={"theme":{"light":"github-light","dark":"dracula"}}
{
  "dependencies": {
    "tailwindcss": "^4",
    "bun-plugin-tailwind": "latest"
  }
}
```

Bun also configures `bunfig.toml` to use its TailwindCSS plugin with `Bun.serve()`:

```toml bunfig.toml icon="settings" theme={"theme":{"light":"github-light","dark":"dracula"}}
[serve.static]
plugins = ["bun-plugin-tailwind"]
```

And writes a `${component}.css` file with `@import "tailwindcss";` at the top:

```css MyComponent.css icon="file-code" theme={"theme":{"light":"github-light","dark":"dracula"}}
@import "tailwindcss";
```

### Using `shadcn/ui` with Bun

[`shadcn/ui`](https://ui.shadcn.com/) is a component library tool for building web applications.

`bun create <component>` scans for any shadcn/ui components imported from `@/components/ui`.

If it finds any, it runs:

```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
# Assuming bun detected imports to @/components/ui/accordion and @/components/ui/button
bunx shadcn@canary add accordion button # and any other components
```

Since `shadcn/ui` itself uses TailwindCSS, `bun create` also adds the TailwindCSS dependencies to your `package.json` and configures `bunfig.toml` to use Bun's TailwindCSS plugin with `Bun.serve()`, as described earlier.

`bun create` also sets up:

* `tsconfig.json` to alias `"@/*"` to `"src/*"` or `.` (depending on whether there is a `src/` directory)
* `components.json` so that shadcn/ui knows it's a shadcn/ui project
* `styles/globals.css` file that configures Tailwind v4 the way shadcn/ui expects
* `${component}.build.ts` file that builds the component for production with `bun-plugin-tailwind` configured

Use `bun create ./MyComponent.jsx` to run code generated by LLMs like [Claude](https://claude.ai) or ChatGPT locally.

## From `npm`

```sh terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun create <template> [<destination>]
```

If you don't have a [local template](#from-a-local-template) with the same name, this command downloads and runs the `create-<template>` package from npm. These two commands are equivalent:

```sh terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun create remix
bunx create-remix
```

Refer to the `create-<template>` package's documentation for usage instructions.

## From GitHub

`bun create <user>/<repo>` downloads the contents of the GitHub repo to disk.

```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun create <user>/<repo>
bun create github.com/<user>/<repo>
```

Optionally specify a name for the destination folder. If you don't, Bun uses the repo name.

```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun create <user>/<repo> mydir
bun create github.com/<user>/<repo> mydir
```

Bun then:

* Downloads the template
* Copies all template files into the destination folder
* Installs dependencies with `bun install`
* Initializes a fresh Git repo. Opt out with the `--no-git` flag.
* Runs the template's configured `start` script, if defined

<Note>By default Bun does *not overwrite* existing files. Use the `--force` flag to overwrite them.</Note>

## From a local template

<Warning>
  Unlike remote templates, running `bun create` with a local template deletes the entire destination folder if it
  already exists.
</Warning>

You can define custom templates on your local file system. Put them in one of the following directories:

* `$HOME/.bun-create/<name>`: global templates
* `<project root>/.bun-create/<name>`: project-specific templates

<Note>Set the `BUN_CREATE_DIR` environment variable to change the global template path.</Note>

To create a local template, create a directory in `$HOME/.bun-create` named after your template.

```bash theme={"theme":{"light":"github-light","dark":"dracula"}}
cd $HOME/.bun-create
mkdir foo
cd foo
```

Then, create a `package.json` file in that directory with the following contents:

```json package.json icon="file-json" theme={"theme":{"light":"github-light","dark":"dracula"}}
{
  "name": "foo"
}
```

Run `bun create foo` elsewhere on your file system to verify that Bun finds your local template.

#### Setup logic

You can specify pre- and post-install setup scripts in the `"bun-create"` section of your local template's `package.json`.

```json package.json icon="file-json" theme={"theme":{"light":"github-light","dark":"dracula"}}
{
  "name": "@bun-examples/simplereact",
  "version": "0.0.1",
  "main": "index.js",
  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2"
  },
  "bun-create": {
    "preinstall": "echo 'Installing...'", // a single command
    "postinstall": ["echo 'Done!'"], // an array of commands
    "start": "bun run echo 'Hello world!'"
  }
}
```

Each field accepts a string or an array of strings. An array of commands runs in order.

| Field         | Description                         |
| ------------- | ----------------------------------- |
| `postinstall` | runs after installing dependencies  |
| `preinstall`  | runs before installing dependencies |

After cloning a template, `bun create` removes the `"bun-create"` section from `package.json` before writing it to the destination folder.

<Accordion title={<span>How <code>bun create</code> works</span>}>
  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 files would be overwritten, warn and exit unless `--force` is passed

  IF GitHub repo

  1. Download the tarball from GitHub’s API
  2. Decompress & extract into `${destination}`
     * If files would be overwritten, 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`; on Linux, `copy_file_range`). Do not copy or traverse into the `node_modules` folder if it 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": { "postinstall" }` with the npm client

  9. Run `git init; git add -A .; git commit -am "Initial Commit";`
     * Rename `gitignore` to `.gitignore`. npm strips `.gitignore` files from published 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
