Installation

This is a Node.js module available through the npm.

$ npm install get-data-router

Principle of operation

This module is designed to create routing from files. The name of your file automatically becomes the name of the route. You can create all possible http protocol protocols in your route

The module is connected through a standard function in Node.js require

const getDataFile = require('get-data-router')

The function is exported to the getDataFile constant.

The function is called and it takes on 2 arguments (path - required, callback - optional)

• path - path to the folder with your files for creating routes

Work without callback

│   │   ├── add.js
│   │   └── edit.js
│   ├──user.js
│   └──index.js
├── router.js
└── index.js

const getDataFile = require('get-data-router')
const data = getDataFile('./routers')

If you do not use callback, you must call the function in a variable or constant and it will give you, for example, the following object:

{
    './routers/index.js': { get: [AsyncFunction: getIndex] },
    './routers/user.js': { 
                            get: { params: ':id', fn: [AsyncFunction: getUser] }, 
                            post: { fn: [AsyncFunction: postUser], mw: [ [Function: multerMiddleware] ] }  
                          },
    './routers/user/add.js': { post: [AsyncFunction: setUser] },
    './routers/user/edit.js': { put: [AsyncFunction: editUser] }
 
}

Work using callback

Pros of using callback:

• Speeds up the development process
• Gives the finished route result

callback takes 4 arguments:

• path - route path. Gives the finished path:

  • ./routers/index.js -> /
  • ./routers/user.js -> /user
  • ./routers/user.js -> /user/:id
  • ./routers/user/add.js -> /user/add
  • ./routers/user/edit.js -> /user/edit

• method - protocol method http

• fn - function for route work

• mw - middleware

Callback example uses framework express

const app = require('express'),
 
      rout = app.Router(),
 
      getDateFile = require('get-date-router')
 
getDateFile('./routers', (path, method, fn, mw) => {
 
    if(mw != undefined) {
        rout[method](path, ...mw, fn)
    } else {
        rout[method](path, fn)
    }
 
})
 
module.exports = rout

Route creation

Using the ./routers/user.js file as an example, consider creating a route

The example uses the multer module to download files and create an additional middleware.

 
 
const upload = require('multer')
 
async function getUser(req, res) {
    res.send('Route works')
}
 
async function postUser(req, res) {
    res.send('Route works')
}
 
module.exports = {
    get: getUser,
    post: {
        fn: postUser,
        mw: [ upload.single('file') ] /* Middleware - must always be an array */
    }
}

 
 
const upload = require('multer')
 
async function getUser(req, res) {
    res.send('Route works')
}
 
async function postUser(req, res) {
    res.send('Route works')
}
 
module.exports = {
    get: {
        params: ':id', /* Rises after the main route  */
        fn: getUser
    },
    post: {
        fn: postUser,
        mw: [ upload.single('file') ] /* Middleware - must always be an array */
    }
}
