Unleash the power of Typescript and Node to create detailed REST API documentation!

Is it possible to generate REST API documentation using https://github.com/TypeStrong/typedoc similar to what can be done with ?

I would appreciate any recommendations on leveraging TypeScript types for creating REST API documentation (specifically within a Next.js environment).

Answer №1

If you're looking to define your API in TypeScript and generate a Swagger/OpenAPI documentation, check out https://github.com/airtasker/spot

This tool not only creates REST API documentation but also allows you to set up a mock server with randomized data that aligns with the API definition (for client testing) as well as a data model validator (for server testing).

Here's an example from the project README:

import { api, endpoint, request, response, body } from "@airtasker/spot";

@api({
  name: "My API"
})
class Api {}

@endpoint({
  method: "POST",
  path: "/users"
})
class CreateUser {
  @request
  request(@body body: CreateUserRequest) {}

  @response({ status: 201 })
  response(@body body: CreateUserResponse) {}
}

interface CreateUserRequest {
  firstName: string;
  lastName: string;
}

interface CreateUserResponse {
  firstName: string;
  lastName: string;
  role: string;
}

Answer №2

Have you taken a look at the npm package apidoc?

This tool is designed to automatically generate API documentation by analyzing code comments:

/**
 * @api {get} /user/:id Request User information
 * @apiName GetUser
 * @apiGroup User
 *
 * @apiParam {Number} id User's unique ID.
 *
 * @apiSuccess {String} firstname Firstname of the User.
 * @apiSuccess {String} lastname  Lastname of the User.
 */

Additionally, there are various companion tools and converters available for Gulp, Grunt, Eclipse, Sublime Text, Docmaster, Markdown, Swagger, and more (see apidoc GitHub README.md)
