how to generate api documentation [closed]

Question

I need to write some api documentation for a REST API that I've created. Are there tools that will stub out a nice html output similar in style to the underscore api documentation? Or perhaps something that will output something as a twitter bootstrap styled html?

I see that docco does annoated code, but I'm actually just looking to document the API only. Ideally I'd like to point a tool at the controller file and have it generate documentation about the methods and routes but not show any source code unless I specifically call out examples.

Answer 1

apiDoc creates a documentation from API annotations in your source code.

Integrated is an API history, with that various API version levels can be compared. So it can be retraced what changed in the API since the last version.

Check out I/O Docs on Github - http://github.com/mashery/iodocs . It's hacked in Node.js, and has a lot of community contribution/involvement. To see it working in the wild:

• http://iodocs.docusign.com
• http://console.datasift.com/datasift

Uber simple configuration schema (JSON), and hell, if you don't want to describe it all by hand in JSON, use I/O Doctor, a web-based tool for importing/building JSON configs with a UI:

• http://iodoctor.net/

Also available on Github at https://github.com/brandonmwest/iodoctor

Let me know if I can help you get started. There are plenty of example configs in the I/O Docs repo. Take care.

Answer 3

I/O Docs or Swagger, which are the most popular RESTful API documentation systems. There is also RAML and Apiary.

test2doc.js helps you generate API documentation from your tests/specs. So you can always get the latest update-to-date API documents, populated with real request/response data.

Test code example:

const doc = require('test2doc')
const request = require('supertest') // We use supertest as the HTTP request library
require('should') // and use should as the assertion library

// For Koa, you should exports app.listen() or app.callback() in your app entry
const app = require('./my-express-app.js')

after(function () {
  doc.emit('api-documentation.apib')
})

doc.group('Products').is(doc => {
  describe('#Products', function () {
    doc.action('Get all products').is(doc => {
      it('should get all products', function () {
        // Write specs towards your API endpoint as you would normally do
        // Just decorate with some utility methods
        return request(app)
          .get(doc.get('/products'))
          .query(doc.query({
            minPrice: doc.val(10, 'Only products of which price >= this value should be returned')
          }))
          .expect(200)
          .then(res => {
            body = doc.resBody(res.body)
            body.desc('List of all products')
              .should.not.be.empty()
            body[0].should.have.properties('id', 'name', 'price')
            body[0].price.desc('Price of this product').should.be.a.Number
          })
      })
    })
  })
})
