Install

    npm install -g @graphidocs/docs

Use

Generate documentation from live endpoint

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

Generate documentation from IDL file

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

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

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

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

Generate documentation from json file

    > graphidocs -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",
        // [...]
        "graphidocs": {
            "endpoint": "http://localhost:8080/graphql",
            "output": "./doc/schema",
        }
    }

And execute

    > graphidocs

Plugin

In graphidocs 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.

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).
• graphidocsPackag: The content of package.json of graphidocs.

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, graphidocsPackage){}
        getAssets() { /* ... */ }
        /* ... */
    }

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

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

    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

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

Built-in plugin

TODO

Template

You can specify which template to use via the CLI:

    > graphidocs -t classic \
                -s ./schema.json -o ./doc/schema

Or via 'package.json':

     // package.json

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

The current built-in templates are:

• classic

Relative Path

The template can also take a relative path (from where command is executed):

    > graphidocs -t ./my-template \
                -s ./schema.json -o ./doc/schema

     // package.json

    {
        "name": "project",
        // [...]
        "graphidocs": {
            "endpoint": "http://localhost:8080/graphql",
            "output": "./doc/schema",
            "template": "./my-template"
        }
    }

Node Module

To specify a node module as a template, specify the name as the template:

    > graphidocs -t my-graphidocs-template \
                -s ./schema.json -o ./doc/schema

     // package.json

    {
        "name": "project",
        // [...]
        "graphidocs": {
            "endpoint": "http://localhost:8080/graphql",
            "output": "./doc/schema",
            "template": "my-graphidocs-template"
        }
    }

Create a Template

All rendering is done within the template. It's up to the template to pick what and how to render. In order to render, you should extend the Template class. There are a few methods you must use:

• getTemplateFiles A way to get all the template files. Should return a promise of strings to the files.
• serialize The method that will turn the data into text that will get written out.
• renderDirective The method that will render the GraphQL directives.
• renderIndex The method that will render the index file like index.html.
• renderType The method that will render the GraphQL types.

An example of this is (from the classic toolkit):

import * as glob from 'glob';
import { render } from 'mustache';
import { TypeRef } from '../../lib/interface';
import Template, { ITemplateFileMap } from '../../lib/Template';
import { getFilenameOf } from '../../lib/utility';
import { ITemplateData } from '../../lib/utility/template';

export default class ClassicTemplate extends Template {
  public async getTemplateFiles(): Promise<string[]> {
    return new Promise<string[]>((resolve, reject) => glob(
      '**/*.mustache',
      { cwd: __dirname },
      (error, files) => error ? reject(error) : resolve(files)
    ));
  }

  public serialize(templateData: ITemplateData, templateFiles: ITemplateFileMap): string {
    return render(templateFiles.index, templateData, templateFiles);
  }

  public renderDirective(type: TypeRef): Promise<void> {
    return this.renderFile(getFilenameOf(type), type);
  }

  public renderIndex(): Promise<void> {
    return this.renderFile('index.html');
  }

  public renderType(type: TypeRef): Promise<void> {
    return this.renderFile(getFilenameOf(type), type);
  }
}
