:rocket: Install

npm install --save express-automatic-routes

:blue_book: Usage

Autoload routes

import express from 'express'
import autoroutes from 'express-automatic-routes'

const app = express()

autoroutes(app, {
  dir: './<autoroutes-directory>' // relative to your cwd
})

Create file in autoroutes directory

//file: `<autoroutes-directory>/some/route.js`
//url:  `http://your-host/some/route`

export default (expressApp) => ({
  get: (request, response) => {
    response.status(200).send('Hello, Route').end()
  }
})

Using typescript support for module

//file: `<autoroutes-directory>/some/route.ts`
//url:  `http://your-host/some/route`

import { Application, Request, Response } from 'express'
import { Resource } from 'express-automatic-routes'

export default (express: Application) => <Resource> {
  get: (request: Request, response: Response) => {
    response.status(200).send('Hello, Route!').end()
  }
}

Accepts params in autoroutes

:information_source: file/directory name must follow syntax :paramName or {paramName}

//file: `<autoroutes-directory>/users/{userId}/photos.js`
//mapped to: `<your host>/users/:userId/photos`

export default (expressApp) => ({
  get: (request, response) => {
      response.end(`photos of user ${request.params.userId}`)
  }
})

:arrow_forward: Module definition

each file must export a function that accept express as parameter, and return an object with the following properties:

export default (expressApp) => ({
  middleware: [ /* your middlewares */ ]
  delete: { /* your handler logic */},
  get: { /* your handler logic */  },
  head: { /* your handler logic */  },
  patch: { /* your handler logic */  },
  post: { /* your handler logic */  },
  put: { /* your handler logic */  },
  options: { /* your handler logic */  },
})

:arrow_forward: Middleware module definition

the middleware parameter can be one of the following:

• undefined (just omit it)
• Middleware function (a function complain to express middleware definition)
• An Array of Middleware functions

example:

:information_source: simple middleware

export default (expressApp) => ({
  middleware: (req, res, next) => next()
  /* ... */
})

:information_source: array of middleware

const m1 = (req, res, next) => next()
const m2 = (req, res, next) => next()

export default (expressApp) => ({
  middleware: [m1, m2]
  /* ... */
})

:arrow_forward: Route definition

A route can be a function (likes middleware but without next parameter) or an object who has the following properties:

• middleware // same as module middleware
• handler // the handler of the function

examples:

:information_source: simple route method

export default (expressApp) => ({
  get: (req, res) => res.send('Hello There!')
})

:information_source: route method with middleware(s)

export default (expressApp) => ({
  get: {
    middleware: (req, res, next) => next()
    handler: (req, res) => res.send('Hello There!')
  }
})

:arrow_forward: Skipping files

to skip file in routes directory, prepend the . or _ charater to filename

examples:

routes
├── .ignored-directory
├── _ignored-directory
├── .ignored-js-file.js
├── _ignored-js-file.js
├── .ignored-ts-file.ts
├── _ignored-ts-file.ts
├── ignored-js-test.test.js
└── ignored-ts-test.test.ts

:warning: also any *.test.js and *.test.ts are skipped!

this is useful if you want to have a lib file containts functions that don't have to be a route, so just create the file with _ prepending character
