Static page generator for documenting GraphQL Schema

Demos

• Facebook Test Star Wars
• Github GraphQL
• Pokemon GraphQL

Install

    npm install -g @2fd/graphdoc

Use

Generate documentation from live endpoint

    > graphdoc -e http://localhost:8080/graphql -o ./doc/schema

Generate documentation from IDL file

    > graphdoc -s ./schema.graphql -o ./doc/schema

Generate documentation from for the "modularized schema" of graphql-tools

    > graphdoc -s ./schema.js -o ./doc/schema

./schema.graphql must be able to be interpreted with graphql-js/utilities#buildSchema

Generate documentation from json file

    > graphdoc -s ./schema.json -o ./doc/schema

./schema.json contains the result of GraphQL introspection query

Puts the options in your package.json

     // package.json

    {
        "name": "project",
        // [...]
        "graphdoc": {
            "endpoint": "http://localhost:8080/graphql",
            "output": "./doc/schema",
        }
    }

And execute

    > graphdoc

Plugin

In graphdoc a plugin is simply an object that controls the content that is displayed on every page of your document.

This object should only implement the PluginInterface.

    /**
     * PluginInterface
     */
    export interface PluginInterface {

        /**
        * Return  section elements that is going to be
        * inserted into the side navigation bar.
        *
        * @example plain javascript:
        * [
        *  {
        *      title: 'Schema',
        *      items: [
        *          {
        *              text: 'Query',
        *              href: './query.doc.html',
        *              isActive: false
        *          },
        *          // ...
        *  }
        *  // ...
        * ]
        *
        * @example with graphdoc utilities:
        * import { NavigationSection, NavigationItem } from 'graphdoc/lib/utility';
        *
        * [
        *  new NavigationSection('Schema', [
        *      new NavigationItem('Query', ./query.doc.html', false)
        *  ]),
        *  // ...
        * ]
        *
        * @param {string} [buildForType] -
        *  the name of the element for which the navigation section is being generated,
        *  if it is `undefined it means that the index of documentation is being generated
        */
        getNavigations?: (buildForType?: string) => NavigationSectionInterface[] | PromiseLike<NavigationSectionInterface[]>;

        /**
        * Return  section elements that is going to be
        * inserted into the main section.
        *
        * @example plain javascript:
        * [
        *  {
        *      title: 'GraphQL Schema definition',

        *
        * @param {string} [buildForType] -

        *  [
        *      '<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>',

        /**
        * Return a list of abasolute path to files that is going to be
        * copied to the assets directory.
        *
        * Unlike the previous methods that are executed each time that a page generated,
        * this method is called a single time before starting to generate the documentation
        *
        * @example
        * [
        *  '/local/path/to/my-custom-style.css',
        *  '/local/path/to/my-custom-image.png',

        * /local/path/to/my-custom-image.png -> [OUTPUT_DIRETORY]/assets/my-custom-image.png
        *
        * If you want to insert styles or scripts to the documentation,
        * you must combine this method with getHeaders
        *
        * @example
        * getAssets(): ['/local/path/to/my-custom-style.css']
        * getHeaders(): ['<link href="assets/my-custom-style.css" rel="stylesheet">']

        getAssets?: () => string[] | PromiseLike<string[]>;

Make a Plugin

To create your own plugin you should only create it as a plain object or a constructor and export it as default

If you export your plugin as a constructor, when going to be initialized, will receive three parameters

• schema: The full the result of GraphQL instrospection query
• projectPackage: The content of package.json of current project (or the content of file defined with --config flag).
• graphdocPackag: The content of package.json of graphdoc.

For performance reasons all plugins receive the reference to the same object and therefore should not modify them directly as it could affect the behavior of other plugins (unless of course that is your intention)

Examples

    // es2015 export constructor
    export default class MyPlugin {
        constructor(schema, projectPackage, graphdocPackag){}
        getAssets() { /* ... */ }
        /* ... */
    }

    // es2015 export plain object
    export default cost myPlugin = {
        getAssets() { /* ... */ },
        /* ... */
    }

    // export constructor
    function MyPlugin(schema, projectPackage, graphdocPackage) { /* ... */ }

    MyPlugin.prototype.getAssets =  function() { /* ... */ };
    /* ... */

    exports.default = MyPlugin;

    // export plain object

    exports.default = {
        getAssets: function() { /* ... */ },
        /* ... */
    }

Use plugin

You can use the plugins in 2 ways.

Use plugins with command line

    > graphdoc  -p graphdoc/plugins/default \
                -p some-dependencie/plugin \
                -p ./lib/plugin/my-own-plugin \
                -s ./schema.json -o ./doc/schema

Use plugins with package.json

     // package.json

    {
        "name": "project",
        // [...]
        "graphdoc": {
            "endpoint": "http://localhost:8080/graphql",
            "output": "./doc/schema",
            "plugins": [
                "graphdoc/plugins/default",
                "some-dependencie/plugin",
                "./lib/plugin/my-own-plugin"
            ]
        }
    }
