collect-express-routes

Collect all API routes in Express Application / Router

This package helps to make "sitemap" of the APIs.

Features

• Support spying express() application and express.Router()
• Support chainable route handlers (app.route)
• Optionally group collected API routes by path (of different HTTP methods)

Usage Example

import express, { Request, Response } from 'express'
import {
  groupRoutesByPath,
  getSpyRoutes,
  spyRoutes,
} from 'collect-express-routes'

let app = express()
spyRoutes(app)

app.use(express.json())

// direct routing is supported
app.get('/users', echo)
app.post('/users', echo)
app.get('/users/:id', echo)
app.patch('/users/:id', echo)
app.delete('/users/:id', echo)

// using router is also supported
let memoRouter = express.Router()
memoRouter.post('/', echo)
memoRouter.get('/:id', echo)
memoRouter.patch('/:id', echo)
memoRouter.delete('/:id', echo)
app.use('/memo', memoRouter)

// chainable route handlers are also supported
app
  .route('/book')
  .get(echo) // alias for app.get('/book', echo)
  .post(echo) // alias for app.post('/book', echo)

console.log(getSpyRoutes(app))
/* output:
[
  { method: 'get', path: '/users' },
  { method: 'post', path: '/users' },
  { method: 'get', path: '/users/:id' },
  { method: 'patch', path: '/users/:id' },
  { method: 'delete', path: '/users/:id' },
  { method: 'post', path: '/memo' },
  { method: 'get', path: '/memo/:id' },
  { method: 'patch', path: '/memo/:id' },
  { method: 'delete', path: '/memo/:id' }
  { method: 'get', path: '/book' },
  { method: 'post', path: '/book' },
]
*/

console.log(groupRoutesByPath(getSpyRoutes(app)))
/* output:
{
  '/users': [ 'get', 'post' ],
  '/users/:id': [ 'get', 'patch', 'delete' ],
  '/memo': [ 'post' ],
  '/memo/:id': [ 'get', 'patch', 'delete' ],
  '/book': [ 'get', 'post' ]
}
*/

function echo(req: Request, res: Response) {
  res.json({ method: req.method, path: req.path })
}
