Plugin documentation

This plugin automates your API documentation creation. It basically generates a swagger file. It follows the Open API specification version 3.0.1. The documentation plugin is not release on npm yet, Here's how to install it.

Usage

  • Config
  • Creating a new documentation version
  • Generated files
    • full_documentation.json structure
  • Overriding the suggested documentation
  • FAQ
    • How does it generate the others plugins documentation ?

  • TODO

Config

The plugin comes with a settings.json file located in my-app/plugins/documentation/config folder where you can specify all your environment variables, licences, external documentation and so one... You can add all the entries listed in the specification.

NOTE if you need to add a custom key you can do it by prefixing your key by x-{something}

Creating a new documentation version

In order to create a new version you need to change the info.version key in the settings.json file.

This will automatically create a new version.

Generated files

When you start your server with this plugin installed it will automatically create the following files in your APIs (we will see how it works for the plugins).

  • api
    • my-api
      • documentation
        • documentationVersion // 1.0.0
          • my-api.json // File containing all the identified path
          • unclassified.json // File containing the manually added paths
          • overrides // Folder to override the generated documentation
  • plugins
    • ...
    • documentation
      • documentation
        • 1.0.0
          • full_documentation.json

full_documentation.json

The combined documentation is merged into the full_documentation.json file and it's located in ./plugins/documentation/{version}/full_documentation.json

It has the following structure

{
  "openapi": "3.0.0" // do not change this version
  "info": {
    "version": "1.0.0" // change this line to create a new version
    ...
  }
  "x-strapi-config": {
    "path": "/documentation", // Change this line to change to url of the doc
    "showGeneratedFiles": true // Do not change this line at the moment...
  },
  "servers" {} // Your servers config (it will be automated),
  "externalDocs": {},
  "paths": {} // All your Api routes,
  "tags": [] // Group of route
  "components": {} // Default generated components and custom ones
}

Overriding the suggested documentation

Currently the plugin writes a json file for each API.

In order to customize the responses or to add informations to a path you need to create a file in the associated overrides/<file-name>.json (the name of the file matters so make sure they are similar). Then you just need to identify the path you want to modify. You can modify the default generated tags by adding a new one at the end of the file. Same for the components.

NOTE 1

Overriding the full_documentation.json is a bad idea since it will be regenerated each time you change a model.

NOTE 2

You can easily modify the description, summary, parameters of a path however, for a response like the 200 you will need to write the full object. Take a look at the ./plugins/users-permissions/documentation/overrides/1.0.0/users-permissions-User.json for a complete example.

FAQ

How does it generate the others plugins documentation ?

In other to reference a plugin's route into the documentation you need to add a description key in the config object.

For example this is the plugin email routes.json file

{
"routes": [
  {
    "method": "POST",
    "path": "/",
    "handler": "Email.send",
    "config": {
      "policies": [],
      "description": "Send an email",
      "tag": {
        "plugin": "email",
        "name": "Email"
      }
    }
  },
  {
    "method": "GET",
    "path": "/environments",
    "handler": "Email.getEnvironments",
    "config": {
      "policies": []
    }
  },
  {
    "method": "GET",
    "path": "/settings/:environment",
    "handler": "Email.getSettings",
    "config": {
      "policies": []
    }
  },
  {
    "method": "PUT",
    "path": "/settings/:environment",
    "handler": "Email.updateSettings",
    "config": {
      "policies": []
    }
  }
]
}

In this file we have only one route that we want to reference in our documentation (/). Usually, the tag object is used for the SWAGGER UI, it will group this route under the Email - Email dropdown in the documentation. Furthermore, the algorithm will try to find the model to generate the best response possible. If the model is unknown it generates a response like the following { foo: "string" } that you can easily override later.

There's another property to guide the algorithm to create the best response possible, the actionType key. When we can't know by the controller name the type of the returned response (like find and findOne) you can specify it with this key. There's an example in ./plugins/users-permissions/config/routes.json.

I have created a route in a common API (like product) that query another model. How to automate this ?

You can use the tag key in your route. If you provide a tag which is a string like "tag": "Product" the algorithm will know that the end-point retrieves data from the Product table. Creating a tag object { "tag": { "name": "User", "plugin": "User-Permissions } } will result in generating a response with the User model from the plugin users-permissions.


Each entry of the object is easily customisable take look at the users-permissions ones they are a good example on how to do it.
