node-autodoc v0.0.7

node-autodoc

A test-driven generator for API documentation. Inspired by autodoc and supertest.

Why need this

Some people are not happy to maintain the API documentation when dealing with the large project. Then, it causes so many confusions and problems when someone new to use previous APIs.

This library is to generate a documentation by given the test cases. It renders the API documentation according to the input and output of each http request.

Work flow

Example

There is also an example inside the repo. Check this out!

Render mode

Default template

It renders the documentation using ejs template engine by default.

Custom template

If you have better templates, you can specify the templateDir to let AutoDoc render your templates. You may want to check out the default templates first, then design your templates.

Custom render function

If you have better idea to render the API doc page, you can also pass a callback in renderPage to make your custom renders.

agent.renderPage((currentAgent) => {
  // Assemable your render data
  const myRenderData = {
    title: currentAgent.title,
    description: currentAgent.description,
    docMetaCollection: currentAgent.docMetaCollection,
    tableOfContent: currentAgent.docMetaCollection.map((docMeta) => ({
      link: `#${encodeURIComponent(docMeta.title)}`,
      title: docMeta.title,
    })),
  };
  
  // Your render function
  customRender(myRenderData);
})

A very common case would be like: Send all the docMetaCollection to your documentation server and generate your own documentation website.

API

Most of the usages are same as supertest. Its APIs are really neat and simple.

The extra APIs this library enhances are below.

AutoDocAgent

const agent = new AutoDocAgent(
  app,
  {
    outputFilename: 'users.html',
    title: 'Users API Documentation',
    description: 'A small and simple documentation for how to deal with /users api',
    outputDir,
    templateDir,
  }
)

AutoDocAgent

options

AutoDocAgent.clear

Clear the given outputDir directory.

AutoDocAgent.clear(outputDir)

AutoDocAgent.renderIndex

Render the home page by given all agents.

AutoDocAgent.renderIndex({
  title: 'My API Documentation',
  description: 'This is my first documentation for testing, haha~',
  author: 'Haixiang',
  agents,
  outputDir,
  templateDir,
});

restful method

When calling the restful method, it's calling the restful method of supertest. The only difference is the second parameter.

agent.get('/users', {
  title: 'Fetch all users',
  description: 'To get all user infomation'
})

title and description would render as the title and description of current API doc.

renderPage

Render current API doc.

agent.renderPage()

If you have better idea to render the API doc page, you can also put a callback in there to make your custom renders.

agent.renderPage((currentAgent) => {
  // Assemable your render data
  const myRenderData = {
    title: currentAgent.title,
    description: currentAgent.description,
    docMetaCollection: currentAgent.docMetaCollection,
    tableOfContent: currentAgent.docMetaCollection.map((docMeta) => ({
      link: `#${encodeURIComponent(docMeta.title)}`,
      title: docMeta.title,
    })),
  };
  
  // Your render function
  customRender(myRenderData);
})
