Description: Documentation generator for `pmndrs/*` projects.

<Intro>
  A static MDX documentation generator, with a GitHub [reusable workflow](./github-actions.mdx). It is primarily used for some `pmndrs/*` projects, but will work for anyone.

[Those projects](https://github.com/search?q=%22uses%3A+pmndrs%2Fdocs%2F.github%2Fworkflows%2Fbuild.yml%22+language%3AYAML&type=code&l=YAML) are known to be using this generator.

## INSTALL

Pre-requisites:

- Install [nvm](https://github.com/nvm-sh/nvm), then:
  ```sh
  $ nvm install
  $ nvm use
  $ node -v # make sure your version satisfies package.json#engines.node
  ```
  nb: if you want this node version to be your default nvm's one:
  `nvm alias default node`

```sh
$ git clone https://github.com/pmndrs/docs.git
$ cd docs
$ pnpm install
```

## Configuration

> [!IMPORTANT]
>
> Default value is always: `""` (think *empty*).

\* Required

<details>
  <summary>`MDX_BASEURL`</summary>

Given a `advanced/introduction.mdx` file in the `MDX` folder:

```md
![](dog.png)
```

becomes (for a `MDX_BASEURL=http://localhost:60141` value):

```md
![](http://localhost:60141/advanced/dog.png)
```

`http://localhost:60141` being the `MDX` folder served.

> [!TIP]
> When deployed on GitHub Pages, `MDX_BASEURL` will typically value something like `https://github.com/pmndrs/uikit/raw/main/docs`, thanks to [`build.yml`](.github/workflows/build.yml) rule.

  <summary>`THEME_*`</summary>

We implement [m3 design system](https://m3.material.io/styles/color/system/overview), using [react-mcu](https://github.com/abernier/react-mcu).

Authoring
URL: /authoring/introduction
Description: How to write documentation

<Intro>
  This is a guide on how to write documentation. We support all [GFM](https://github.github.com/gfm/) syntax, plus some custom components that are described here.
</Intro>

<Keypoints>
  <KeypointsItem>[Front matter](#frontmatter) metadatas</KeypointsItem>
  <KeypointsItem>Custom [markdown](#markdown) components</KeypointsItem>
</Keypoints>

In your `MDX` folder, create any `path/to/my-document.mdx`:

```md
---
title: My Document
description: Lorem ipsum...
nav: 0
image: dog.png
sourcecode: to/my-document.mdx
---

MARKDOWN
```

## Frontmatter

Any key is optional.

- `title`: if not provided, last part of the path is used: `my document`
- `description`
- `sourcecode`: relative path to the source-code file
- `image`:
  - relative (to the md file) or absolute path, eg: `dog.png`, `./dog.png`, `../../dog.png`, `/dog.png` or `https://animals.com/dog.png`
  - will be used as metadata image if provided
- `nav`: order in the navigation (on the same level)

## MARKDOWN

Worth mentioning, you can use **standard HTML**, with [tailwind](https://tailwindcss.com) support:

```md
<div>
  <iframe src="https://drei.pmnd.rs/iframe.html?globals=&args=&id=staging-accumulativeshadows--accumulative-shadow-st&viewMode=story" 
    className="w-full h-60 rounded-lg"
  />
  <p className="mt-1 text-xs text-on-surface-variant">This is an embed iframe of [Drei's `<AccumulativeShadows>` story](https://drei.pmnd.rs/?path=/docs/staging-accumulativeshadows--docs).</p>
</div>
```

result:

<div>
  <iframe src="https://drei.pmnd.rs/iframe.html?globals=&args=&id=staging-accumulativeshadows--accumulative-shadow-st&viewMode=story" 
    className="w-full h-60 rounded-lg"
  />
  <p className="mt-1 text-xs text-on-surface-variant">This is an embed iframe of [Drei's `<AccumulativeShadows>` story](https://drei.pmnd.rs/?path=/docs/staging-accumulativeshadows--docs).</p>
</div>

> [!TIP]
>
> We use [react-mcu](https://github.com/abernier/react-mcu) colors, eg: `text-on-surface-variant` above

Plus:
- any [GitHub Flavored Markdown](https://github.github.com/gfm/) syntax.
- all exported [`components/mdx/index.tsx`](components/mdx/index.tsx) MDX components.

See the following pages for detailed documentation on each custom component.

---

Intro
URL: /authoring/intro
Description: Introduction component for documentation pages

<Intro>
  Prominent introduction with rich markdown support.
</Intro>

Use at the top of the document, just after the frontmatter.

```md
<Intro>
  This is an intro. Here you can write a long description of the article, longer than the frontmatter `description`, eventually with [links](#), lists, etc.
  
  Multiple paragraphs are also possible, or anything.
</Intro>
```

result:

<Intro>
  This is an intro. Here you can write a long description of the article, longer than the frontmatter `description`, eventually with [links](#), lists, etc.
  
  Multiple paragraphs are also possible, or anything.
</Intro>

---

Keypoints
URL: /authoring/keypoints
Description: Keypoints component for highlighting main article topics

<Intro>
  Highlights key takeaways as a visually distinct bulleted list.
</Intro>

Can be used after `Intro`, to list main points the article covers: one bullet per `KeypointsItem`.

```md
<Keypoints title="What you'll learn">
  <KeypointsItem>First item</KeypointsItem>
  <KeypointsItem>Second **item**</KeypointsItem>
</Keypoints>
```

result:

<Keypoints title="What you'll learn">
  <KeypointsItem>First item</KeypointsItem>
  <KeypointsItem>Second **item**</KeypointsItem>
</Keypoints>

---

Img
URL: /authoring/img
Description: Using images in documentation

<Intro>
  Display images using markdown or HTML syntax with automatic dimensions and relative path support.
</Intro>

Relative images are supported. Eg, inside your [`MDX`](introduction#configuration:~:text=MDX) folder:
```text {2}
|-- authoring
|   |-- img.mdx  <= relative to this article
|   `-- gutenberg.jpg
```

```md
---
title: Authoring
---

![](gutenberg.jpg)
```

result:

![](gutenberg.jpg)

> [!TIP]
> You are encouraged to use relative images, since dimensions are automatically added as `img[width][height]` attributes.
>
> For others, think about adding them to **prevent layout shift**.

---

It is also possible to specify only one dimension (other is inferred from intrinsic ratio), eg:

```md
<img src="gutenberg.jpg" height="200" />
```

result:

<img src="gutenberg.jpg" height="200" />

---

Although it is probably better to use CSS for this:

```md
<img src="gutenberg.jpg" style={{width: 'auto', height: '10rem'}} />
```

result:

<img src="gutenberg.jpg" style={{width: 'auto', height: '10rem'}} />

> [!NOTE]
> See [`MDX_BASEURL`](introduction#configuration:~:text=MDX_BASEURL) to understand how it is converted to a full URL.

---

Code
URL: /authoring/code
Description: Code blocks with syntax highlighting and line numbers

<Intro>
  Code blocks with syntax highlighting.
</Intro>

Line numbers/highlights are supported:

````md
```tsx {1,4-6} showLineNumbers
type Props = {who: string}

function Hi({who}: Props) {
  return (
    <p>Hello, {who}!</p>
  )
}
```
````

result:

```tsx {1,4-6} showLineNumbers
type Props = {who: string}

function Hi({who}: Props) {
  return (
    <p>Hello, {who}!</p>
  )
}
```

---

You can start at a specific `X` line number `showLineNumbers=X`:

````md
```tsx {1,4-6} showLineNumbers=150
type Props = {who: string}

function Hi({who}: Props) {
  return (
    <p>Hello, {who}!</p>
  )
}
```
````

result:

```tsx {1,4-6} showLineNumbers=150
type Props = {who: string}

function Hi({who}: Props) {
  return (
    <p>Hello, {who}!</p>
  )
}
```

---

`diff` format is supported:

````md
```diff
diff --git a/example.txt b/example.txt
index 8c3317a..47ea956 100644
--- a/example.txt
+++ b/example.txt

/>

> [!TIP]
> Sandpack UI SSR-rendering[^1] is also supported (out of the box).

[^1]: https://sandpack.codesandbox.io/docs/guides/ssr#nextjs-app-dir  

#### `Sandpack[folder]`

Instead of `files`, a `folder` prop allows you to pass a folder containing all the files:

```tsx
<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
/>
```

`folder` path is relative to the `.mdx` file:

```text
|-- getting-started
|   |-- authoring.mdx             <= relative to this article
|   `-- authoring-sandpack-cloud     <= the folder
```

> [!TIP]
> It will simply:
> - build the `files` prop for you (including all `.{js|ts|jsx|tsx|css}` it finds)
> - build `customSetup.dependencies` from `package.json` if it exists

result:

<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
/>

---

It is also possible to pass some individual [file format](https://sandpack.codesandbox.io/docs/getting-started/usage#file-format) configuration:

```tsx
<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  files={{
    '/App.tsx': {
      readOnly: true,
      active: true,
    },
    '/styles.css': {
      hidden: true
    }
  }}
/>
```

result:

<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  files={{
    '/App.tsx': {
      readOnly: true,
      active: true,
    },
    '/styles.css': {
      hidden: true
    }
  }}
/>

#### `Sandpack[fileExplorer]`

```tsx
<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  fileExplorer
/>
```

result:

<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  fileExplorer
/>

> [!TIP]
> Conveniently, enabling `fileExplorer` will by default `[codeEditor={showTabs: false}]`.
> You can override it with [`[codeEditor]` options](#sandpack[codeeditor])

---

You can also pass [any `fileExplorer={options: ComponentProps<SandpackFileExplorer>}`](https://sandpack.codesandbox.io/docs/advanced-usage/components#file-explorer:~:text=Preview-,Options,-If%20you%27re%20looking).

#### `Sandpack[codeEditor]`

You can pass [any `codeEditor={options: ComponentProps<SandpackCodeEditor>}`](https://sandpack.codesandbox.io/docs/advanced-usage/components#code-editor:~:text=Preview-,Options,-Extensions).

#### `Sandpack[codeViewer]`

It will render the [`SandpackCodeViewer`](https://sandpack.codesandbox.io/docs/advanced-usage/components#code-viewer) instead of the default [`SandpackCodeEditor`](https://sandpack.codesandbox.io/docs/advanced-usage/components#code-editor).

```tsx
<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  codeViewer
/>
```

result:

<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  codeViewer
/>

You can also pass [any `codeViewer={options: ComponentProps<SandpackCodeViewer>}`](https://sandpack.codesandbox.io/docs/advanced-usage/components#code-viewer:~:text=Preview-,Options,-CodeMirror%20decorations).

##### `Sandpack[codeViewer][filesDecorators]`

You can define per-file [decorators](https://sandpack.codesandbox.io/docs/advanced-usage/components#codemirror-decorations) through `filesDecorators` prop:

```tsx
<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  codeViewer={{
    filesDecorators: {
      '/App.tsx': [
        { className: "highlight", line: 1 },
        { className: "highlight", line: 7 },
        {
          className: "widget",
          elementAttributes: { "data-id": "1" },
          line: 7,
          startColumn: 13,
          endColumn: 24,
        },
        {
          className: "widget",
          elementAttributes: { "data-id": "2" },
          line: 7,
          startColumn: 25,
          endColumn: 35,
        },
        
      ],
      '/styles.css': [
        { className: "highlight", line: 4 },
      ]
    }
  }}
/>
```

result:

<Sandpack
  template="react-ts"
  folder="authoring-sandpack-cloud"
  codeViewer={{
    filesDecorators: {
      '/App.tsx': [
        { className: "highlight", line: 1 },
        { className: "highlight", line: 7 },
        {
          className: "widget",
          elementAttributes: { "data-id": "1" },
          line: 7,
          startColumn: 13,
          endColumn: 24,
        },
        {
          className: "widget",
          elementAttributes: { "data-id": "2" },
          line: 7,
          startColumn: 25,
          endColumn: 35,
        },
        
      ],
      '/styles.css': [
        { className: "highlight", line: 4 },
      ]
    }
  }}
/>

#### `Sandpack[preview]`

You can pass [any `preview={options: ComponentProps<SandpackPreview>}`](https://sandpack.codesandbox.io/docs/advanced-usage/components#preview:~:text=Preview-,Options,-Additional%20buttons).
