+# Turborepo Design System Starter

-Package basics
+This guide explains how to use a React design system starter powered by:
+
+- 🏎 [Turborepo](https://turbo.build/repo) — High-performance build system for Monorepos
+- 🚀 [React](https://reactjs.org/) — JavaScript library for user interfaces
+- 🛠 [Tsup](https://github.com/egoist/tsup) — TypeScript bundler powered by esbuild
+- 📖 [Storybook](https://storybook.js.org/) — UI component environment powered by Vite
+
+As well as a few others tools preconfigured:
+
+- [TypeScript](https://www.typescriptlang.org/) for static type checking
+- [ESLint](https://eslint.org/) for code linting
+- [Prettier](https://prettier.io) for code formatting
+- [Changesets](https://github.com/changesets/changesets) for managing versioning and changelogs
+- [GitHub Actions](https://github.com/changesets/action) for fully automated package publishing
+
+## Using this example
+
+Run the following command:
+
+```sh
+npx create-turbo@latest -e design-system
+```
+
+### Useful Commands
+
+- `pnpm build` - Build all packages, including the Storybook site
+- `pnpm dev` - Run all packages locally and preview with Storybook
+- `pnpm lint` - Lint all packages
+- `pnpm changeset` - Generate a changeset
+- `pnpm clean` - Clean up all `node_modules` and `dist` folders (runs each package's clean script)
+
+## Turborepo
+
+[Turborepo](https://turbo.build/repo) is a high-performance build system for JavaScript and TypeScript codebases. It was designed after the workflows used by massive software engineering organizations to ship code at scale. Turborepo abstracts the complex configuration needed for monorepos and provides fast, incremental builds with zero-configuration remote caching.
+
+Using Turborepo simplifies managing your design system monorepo, as you can have a single lint, build, test, and release process for all packages. [Learn more](https://vercel.com/blog/monorepos-are-changing-how-teams-build-software) about how monorepos improve your development workflow.
+
+## Apps & Packages
+
+This Turborepo includes the following packages and applications:
+
+- `apps/docs`: Component documentation site with Storybook
+- `packages/ui`: Core React components
+- `packages/utils`: Shared React utilities
+- `packages/typescript-config`: Shared `tsconfig.json`s used throughout the Turborepo
+- `packages/eslint-config`: ESLint preset
+
+Each package and app is 100% [TypeScript](https://www.typescriptlang.org/). Workspaces enables us to "hoist" dependencies that are shared between packages to the root `package.json`. This means smaller `node_modules` folders and a better local dev experience. To install a dependency for the entire monorepo, use the `-w` workspaces flag with `pnpm add`.
+
+This example sets up your `.gitignore` to exclude all generated files, other folders like `node_modules` used to store your dependencies.
+
+### Compilation
+
+To make the core library code work across all browsers, we need to compile the raw TypeScript and React code to plain JavaScript. We can accomplish this with `tsup`, which uses `esbuild` to greatly improve performance.
+
+Running `pnpm build` from the root of the Turborepo will run the `build` command defined in each package's `package.json` file. Turborepo runs each `build` in parallel and caches & hashes the output to speed up future builds.
+
+For `acme-core`, the `build` command is the following:
+
+```bash
+tsup src/index.tsx --format esm,cjs --dts --external react
+```
+
+`tsup` compiles `src/index.tsx`, which exports all of the components in the design system, into both ES Modules and CommonJS formats as well as their TypeScript types. The `package.json` for `acme-core` then instructs the consumer to select the correct format:
+
+```json:acme-core/package.json
+{
+  "name": "@acme/core",
+  "version": "0.0.0",
+  "main": "./dist/index.js",
+  "module": "./dist/index.mjs",
+  "types": "./dist/index.d.ts",
+  "sideEffects": false,
+}
+```
+
+Run `pnpm build` to confirm compilation is working correctly. You should see a folder `acme-core/dist` which contains the compiled output.
+
+```bash
+acme-core
+└── dist
+    ├── index.d.ts  <-- Types
+    ├── index.js    <-- CommonJS version
+    └── index.mjs   <-- ES Modules version
+```
+
+## Components
+
+Each file inside of `acme-core/src` is a component inside our design system. For example:
+
+```tsx:acme-core/src/Button.tsx
+import * as React from 'react';
+
+export interface ButtonProps {
+  children: React.ReactNode;
+}
+
+export function Button(props: ButtonProps) {
+  return <button>{props.children}</button>;
+}
+
+Button.displayName = 'Button';
+```
+
+When adding a new file, ensure the component is also exported from the entry `index.tsx` file:
+
+```tsx:acme-core/src/index.tsx
+import * as React from "react";
+export { Button, type ButtonProps } from "./Button";
+// Add new component exports here
+```
+
+## Storybook
+
+Storybook provides us with an interactive UI playground for our components. This allows us to preview our components in the browser and instantly see changes when developing locally. This example preconfigures Storybook to:
+
+- Use Vite to bundle stories instantly (in milliseconds)
+- Automatically find any stories inside the `stories/` folder
+- Support using module path aliases like `@acme-core` for imports
+- Write MDX for component documentation pages
+
+For example, here's the included Story for our `Button` component:
+
+```js:apps/docs/stories/button.stories.mdx
+import { Button } from '@acme-core/src';
+import { Meta, Story, Preview, Props } from '@storybook/addon-docs/blocks';
+
+<Meta title="Components/Button" component={Button} />
+
+# Button
+
+Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec euismod, nisl eget consectetur tempor, nisl nunc egestas nisi, euismod aliquam nisl nunc euismod.
+
+## Props
+
+<Props of={Box} />
+
+## Examples
+
+<Preview>
+  <Story name="Default">
+    <Button>Hello</Button>
+  </Story>
+</Preview>
+```
+
+This example includes a few helpful Storybook scripts:
+
+- `pnpm dev`: Starts Storybook in dev mode with hot reloading at `localhost:6006`
+- `pnpm build`: Builds the Storybook UI and generates the static HTML files
+- `pnpm preview-storybook`: Starts a local server to view the generated Storybook UI
+
+## Versioning & Publishing Packages
+
+This example uses [Changesets](https://github.com/changesets/changesets) to manage versions, create changelogs, and publish to npm. It's preconfigured so you can start publishing packages immediately.
+
+You'll need to create an `NPM_TOKEN` and `GITHUB_TOKEN` and add it to your GitHub repository settings to enable access to npm. It's also worth installing the [Changesets bot](https://github.com/apps/changeset-bot) on your repository.
+
+### Generating the Changelog
+
+To generate your changelog, run `pnpm changeset` locally:
+
+1. **Which packages would you like to include?** – This shows which packages and changed and which have remained the same. By default, no packages are included. Press `space` to select the packages you want to include in the `changeset`.
+1. **Which packages should have a major bump?** – Press `space` to select the packages you want to bump versions for.
+1. If doing the first major version, confirm you want to release.
+1. Write a summary for the changes.
+1. Confirm the changeset looks as expected.
+1. A new Markdown file will be created in the `changeset` folder with the summary and a list of the packages included.
+
+### Releasing
+
+When you push your code to GitHub, the [GitHub Action](https://github.com/changesets/action) will run the `release` script defined in the root `package.json`:
+
+```bash
+turbo run build --filter=docs^... && changeset publish
+```
+
+Turborepo runs the `build` script for all publishable packages (excluding docs) and publishes the packages to npm. By default, this example includes `acme` as the npm organization. To change this, do the following:
+
+- Rename folders in `packages/*` to replace `acme` with your desired scope
+- Search and replace `acme` with your desired scope
+- Re-run `pnpm install`
+
+To publish packages to a private npm organization scope, **remove** the following from each of the `package.json`'s
+
+```diff
+- "publishConfig": {
+-  "access": "public"
+- },
+```

+# 0.12.1 (2017-02-24)
+- Typescript port complete
+- all tests passing
+
+# 0.11.0 (2017-02-09)
+- Added input validation for the whole API
+- **(breaking change)** Removed already deprecated option `buf` for `read()` method
+
+# 0.10.5 (2016-12-07)
+- Fixed `find()` bug when `directories` is set to `true` and only negation glob is used.
+
+# 0.10.4 (2016-12-06)
+- Fixed matcher edge cases, improved matcher tests (affects `find()` and `copy()` methods).
+
+# 0.10.3 (2016-11-23)
+- Fixed directory tree traversal bug which was causing problems for `findAsync()` and `copyAsync()`.
+
+# 0.10.2 (2016-11-08)
+- Fixed `console.log(jetpack)` for node v6.6.0 or newer.
+
+# 0.10.1 (2016-11-01)
+- Bugfixed case when `copyAsync()` was leaving open read stream if write stream errored.
+- Tests ported from jasmine to mocha.
+
+# 0.10.0 (2016-10-17)
+- `copyAsync()` uses only streams (much more memory efficient).
+- `find()` supports `recursive` option.
+
+# 0.9.2 (2016-06-27)
+- Updated third party dependencies to quell minimatch intallation warnings.
+
+# 0.9.1 (2016-05-21)
+- Bug-fixed `jetpack.read('nonexistent_file', 'json')`.
+
+# 0.9.0 (2016-05-10)
+- **(breaking change)** `read()`, `list()`, `inspect()` and `inspectTree()` returns `undefined` instead of `null` if path doesn't exist.
+- More sane edge cases for `dir()`, `file()` and `list()`.
+
+# 0.8.0 (2016-04-09)
+- **(breaking change)** `find()` now distinguishes between files and directories and by default searches only for files (previously searched for both).
+- **(breaking change)** `find()` no longer can be configured with `returnAs` parameter and returns always relative paths (previously returned absolute).
+- **(breaking change)** `list()` no longer accepts `useInspect` as a parameter. To achieve old behaviour use `jetpack.list()` with `Array.map()`.
+- **(deprecation)** Don't do `jetpack.read('sth', 'buf')`, do `jetpack.read('sth', 'buffer')` instead.
+- `remove()`, `list()` and `find()` now can be called without provided `path`, and defaults to CWD in that case.
+
+# 0.7.3 (2016-03-21)
+- Bugfixed `copy()` with symlink overwrite
+
+# 0.7.2 (2016-03-09)
+- Fixed .dotfiles copying
+
+# 0.7.1 (2015-12-17)
+- Updated third party dependencies.
+
+# 0.7.0 (2015-07-20)
+- **(breaking change)** `matching` option in `copy()` and `find()` resolves glob patterns to the folder you want copy or find stuff in (previously CWD was used).
+
+# 0.6.5 (2015-06-19)
+- `exists()` can handle ENOTDIR error.
+
+# 0.6.3 and 0.6.4 (2015-04-18)
+- Added support for symbolic links.
+
+# 0.6.2 (2015-04-07)
+- Option `matching` in `copy()` and `find()` now accepts patterns anchored to CWD.
+
+# 0.6.1 (2015-04-03)
+- Option `matching` in `copy()` and `find()` now accepts negation patterns (e.g. `!some/file.txt`).
+
+# 0.6.0 (2015-03-30)
+- Lots of code refactoring
+- **(breaking change)** `dir()` no longer has `exists` option.
+- **(breaking change)** `file()` no longer has `exists` and `empty` options.
+- **(breaking change)** `safe` option for `write()` renamed to `atomic` (and uses new algorithm under the hood).
+- **(breaking change)** `safe` option for `read()` dropped (`atomic` while writing is enough).
+- **(breaking change)** In `copy()` options `only` and `allBut` have been replaced by option `matching`.
+- **(breaking change)** In `remove()` options `only` and `allBut` have been dropped (to do the same use `find()`, and then remove).
+- **(breaking change)** Default jsonIndent changed form 0 to 2.
+- `find()` method added.
+- More telling errors when `read()` failed while parsing JSON.
+
+# 0.5.3 (2015-01-06)
+- `inspect()` can return file access/modify/change time and mode.
+
+# 0.5.2 (2014-09-21)
+- `inspect()` checksum of empty file is now `null`.
+
+# 0.5.1 (2014-09-21)
+- `cwd()` accepts many arguments as path parts.
+
+# 0.5.0 (2014-08-31)
+- **(breaking change)** Method `tree()` renamed to `inspectTree()`.
+- **(breaking change)** Parameters passed to `list()` has changed.
+- Methods `inspect()` and `inspectTree()` can calculate md5 and sha1 checksums.
+- Added aliases to `fs.createReadStream()` and `fs.createWriteStream()`.
+
+# 0.4.1 (2014-07-16)
+- `copy()` now copies also file permissions on unix systems.
+- `append()` can specify file mode if file doesn't exist.
+- Can indent saved JSON data.
+
+# 0.4.0 (2014-07-14)
+- Changelog starts here.

+# Cool things about fs-jetpack in examples
+**Note:** All examples here are synchronous for simplicity. You can easily make them asynchronous just by adding 'Async' to method names and expecting promise to be returned instead of ready value.
+
+## Every jetpack instance has its internal CWD
+You can create many jetpack objects with different internal working directories (which are independent of `process.cwd()`) and work on directories in a little more object-oriented manner.
+```js
+var src = jetpack.cwd('path/to/source');
+var dest = jetpack.cwd('path/to/destination');
+src.copy('foo.txt', dest.path('bar.txt'));
+```
+
+## JSON is a first class citizen
+You can write JavaScript object directly to disk and it will be transformed to JSON automatically.
+```js
+var obj = { greet: "Hello World!" };
+jetpack.write('file.json', obj);
+```
+Then you can get your object back just by telling read method that it's a JSON.
+```js
+var obj = jetpack.read('file.json', 'json');
+```
+
+## Jetpack throws errors at you as the last resort
+Everyone who did something with files for sure seen (and probably hates) *"ENOENT, no such file or directory"* error. Jetpack tries to recover from that error if possible.  
+1. For write/creation operations, if any of parent directories doesn't exist jetpack will just create lacking directories.  
+2. For read/inspect operations, if file or directory doesn't exist `undefined` is returned instead of throwing.
+
+## Jetpack is great for build scripts
+```js
+var src = jetpack.cwd('path/to/source');
+var dest = jetpack.dir('path/to/destination', { empty: true });
+
+src.copy('.', dest.path(), {
+    matching: ['./vendor/**', '*.html', '*.png', '*.jpg']
+});
+
+var config = src.read('config.json', 'json');
+config.env = 'production';
+dest.write('config.json', config);
+```
+
+## All methods play nicely with each other
+Let's say you want to create folder structure:
+```
+.
+|- greets
+   |- greet.txt
+   |- greet.json
+|- greets-i18n
+   |- polish.txt
+```
+Peace of cake with jetpack!
+```js
+jetpack
+.dir('greets')
+    .file('greet.txt', { content: 'Hello world!' })
+    .file('greet.json', { content: { greet: 'Hello world!' } })
+    .cwd('..')
+.dir('greets-i18n')
+    .file('polish.txt', { content: 'Witaj świecie!' });
+```
+
+## Find and delete all `.tmp` files inside `my-dir`
+```js
+jetpack.find('my-dir', {
+    matching: '*.tmp'
+})
+.forEach(jetpack.remove);
+```
+
+## Check if two files have the same content
+```js
+var file1 = jetpack.inspect('file1', { checksum: 'md5' });
+var file2 = jetpack.inspect('file2', { checksum: 'md5' });
+var areTheSame = (file1.md5 === file2.md5);
+```
+
+## More secure writes to disk
+For essential data you might consider "atomic write" feature. To read more about "why" and "how" please see: [Transactionally writing files in Node.js](http://stackoverflow.com/questions/17047994/transactionally-writing-files-in-node-js) Jetpack implements this simple trick and makes it available as an option.
+```js
+jetpack.write('important_config.json', { atomic: true });
+```
