gatsby-theme-apollo-docs

This is an entirely configuration-based Gatsby theme that generates a documentation website based on a series of Markdown or MDX files. It also exports a series of components that can be used within MDX pages.

Installation

If you’re using this package, you’ll also need to install gatsby and its peer dependencies, react and react-dom. Next, install the theme:

$ npm install gatsby-theme-apollo-docs

Configuration

You can configure gatsby-theme-apollo-docs for use with any set of docs using the provided configuration options. You may also use component shadowing to customize elements like the logo or color scheme.

// gatsby-config.js
module.exports = {
  pathPrefix: '/docs/apollo-server',
  plugins: [
    {
      resolve: 'gatsby-theme-apollo-docs',
      options: {
        root: __dirname,
        subtitle: 'Apollo Server',
        description: 'A guide to using Apollo Server',
        githubRepo: 'apollographql/apollo-server',
        defaultVersion: '2',
        versions: {
          '1': 'version-1'
        },
        sidebarCategories: {
          null: [
            'index',
            'getting-started',
            'whats-new'
          ],
          Features: [
            'features/mocking',
            'features/errors',
            'features/data-sources'
          ]
        }
      }
    }
  ]
};

Options

Option name Type Required Description
root string Yes Must be __dirname
siteName string Yes The main title for the website, used in the <title> element and top left corner of the site
description string Yes The site description for SEO and social (FB, Twitter) tags
sidebarCategories object Yes An object mapping categories to page paths (see sidebarCategories reference)
subtitle string No The page title that gets rendered above the sidebar navigation
pageTitle string No The string to be rendered in the page’s <title> tag. If omitted, siteName will be used.
baseDir string No If your Gatsby site does not live in the root of your project directory/git repo, pass the subdirectory name here (docs, for example)
contentDir string No The directory where docs content exists (content by default)
githubRepo string No The owner and name of the content repository on GitHub
spectrumPath string No The path to be appended to Spectrum links
segmentApiKey string No Your Segment API key
algoliaApiKey string No Your Algolia DocSearch API key
algoliaIndexName string No The name of your DocSearch index
baseUrl string No The origin where your website will be hosted (e.g. https://www.apollographql.com)
spectrumHandle string No Your Spectrum community’s handle/slug
twitterHandle string No Your Twitter handle, without the ”@”
youtubeUrl string No The URL of your YouTube channel
defaultVersion string No An identifier for the default selected version, served at the root of the docset (/)
localVersion string No If the local files represent a version different from the defaultVersion, specify an identifier for the local version here
versions array No An array of objects representing the versions that the website should generate
navConfig object No An object defining the top-left navigation links (see navConfig reference)
checkLinksOptions object No Options accepted by gastby-remark-check-links

versions

If omitted, only one version of docs will be built, based on the files in the theme consumer repository. If provided, the versions option expects an object mapping older versions’ labels to their respective git branch. The current filesystem will still determine the “default” version. The default label for this version is “Latest”, but is configurable by the defaultVersion option.

defaultVersion: '2.5',
versions: {
  '2.4': 'version-2.4'
}

sidebarCategories

The sidebarCategories option is an object keyed by category titles. Each entry in the object is an array of page paths. The path should resemble the location of a Markdown/MDX file in the git repository, relative to contentDir, and without the .md extension. Sidebar navigation items that are not a member of a category live under the null key. To add an external link to your sidebar, your can provide a string formatted like a Markdown link.

{
  null: [
    'index',
    'getting-started',
    'whats-new'
  ],
  Features: [
    'features/mocking',
    'features/errors',
    'features/data-sources'
  ],
  'External links': [
    '[Principled GraphQL](https://principledgraphql.com/)'
  ]
}

The navConfig option should be an object keyed by link titles. The values should be objects with description, and url properties. Check out the default theme options for an example of the expected shape of this data.

Creating pages

This theme generates pages based on Markdown or MDX files in the contentDir directory of a repo. Your Markdown/MDX files should contain some frontmatter defining their titles and descriptions.

---
title: Introduction
description: What is Apollo Server and what does it do?
---

Apollo Server is the best way to quickly build a production-ready, self-documenting API for GraphQL clients, using data from any source.

Page URLs will be derived from the file paths of your Markdown. You can nest Markdown files within directories to create pages with additional path segments.

Component shadowing

You can customize a website using this theme further by taking advantage of component shadowing.

By default, this theme sets the website favicon to the one from Apollo’s website within its internal SEO component. If you wanted to use your own favicon, you could shadow the SEO component within your site and add your custom SEO/favicon implementation.

// src/gatsby-theme-apollo-docs/components/seo.js
import React from 'react';
import {Helmet} from 'react-helmet';

export default function SEO({title, description, siteName}) {
  return (
    <Helmet>
      <link rel="icon" href="/path/to/custom-favicon.ico" />
      {/* other SEO tags (OpenGraph, Twitter, etc.) */}
    </Helmet>
  );
}

Components

This theme exports React components that you can use in MDX files throughout a documentation website.

ExpansionPanel

An expandable panel of content used to hide complex information or instructions that might be a tangent from the main topic of the content it lives within.

Prop Type Description
children node The content of the panel, usually includes an ExpansionPanelList
title string The title of the panel, visible even when the panel is closed

ExpansionPanelList

A wrapper element that should be used in conjunction with ExpansionPanelListItem components. It renders an li element with some styles baked in.

ExpansionPanelListItem

A list item for use with the ExpansionPanelList. It comes with a cicular area to its left to render a number, glyph, or some way to indicate progress through a set of instructions. You can write Markdown within these elements if you keep everything detabbed and add an empty line between your content and the component’s opening and closing tags.

Prop Type Description
children node The content of the list item, usually a block of Markdown
number string The number displayed to the left of the list item, or a checkmark if “check” is passed
import {
  ExpansionPanel,
  ExpansionPanelList,
  ExpansionPanelListItem
} from 'gatsby-theme-apollo-docs';

<ExpansionPanel title="How to use the ExpansionPanel component">

Add a line break _between_ JSX tags and content to parse the content as *Markdown*

<ExpansionPanelList>
<ExpansionPanelListItem number="1">

<h4>h4 works well as a heading here</h4>

- markdown
- works
- here

</ExpansionPanelListItem>
<ExpansionPanelListItem number="check">

<h4>That's it!</h4>

> MDX is super fun

</ExpansionPanelListItem>
</ExpansionPanelList>

</ExpansionPanel>

MultiCodeBlock

Wraps adjacent code blocks to allow users to toggle between them using a dropdown menu.

import {MultiCodeBlock} from 'gatsby-theme-apollo-docs';

<MultiCodeBlock>

```js
// a JavaScript code block
```

```ts
// a TypeScript code block
```

</MultiCodeBlock>

Deployment

All docs sites will eventually be deployed into a subdirectory, as configured by the pathPrefix option—/docs/apollo-server, for example. Read this guide to learn more about publishing to a subdirectory.
