Generate GraphQL docs from schema.

• install
• use
• plugin

Forked from the excellent but unfortunately unmaintained graphdoc package.

Install

To install globally:

    npm install -g graphqldoc

Use

Generate documentation from live endpoint

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

Generate documentation from IDL file

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

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

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

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

Generate documentation from json file

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

And execute

    > graphqldoc

Plugin

In graphqldoc 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).
• graphqldocPackage: The content of package.json of graphqldoc.

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

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

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

    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

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