fast-custom-router

This is a powerful custom enrober for express router.

Installation

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

Before installing, download and install Node.js v14.X.X or higher.

Installation is done using the npm install command:

npm install fast-custom-router

Features

• strict configuration parser
• dynamic module imports (middlewares and controllers)
• type checking (uri params and body params)
• modular configuration files (with imports)

Quick start

First of all, you will need to use a router such as Express.

Then create one configuration file, for example:

# config/config.yaml

api:
  root: /api
  pre_middlewares:
    - authenticate
  post_middlewares:
    - errorHandler
  routes:
    user:
      path: /user/:id
      params:
        id: number
      methods:
        GET:
          controller: user/user:getUser
        DELETE:
          controller: user/deleteUser
          pre_middlewares:
            - checkUserPermissions
          post_middlewares:
            - logRequests

Then your main script launcher:

// main.js

import { dirname, join } from 'path'
import { fileURLToPath } from 'url'

import http from 'http'
import Express from 'express'

import { Parser as APIParser } from 'fast-custom-router'

/** Configuration */
const __dirname = dirname(fileURLToPath(import.meta.url))
const config = {
  config_dir: join(__dirname, 'config'),
  controller_dir: join(__dirname, 'controller'),
  middleware_dir: join(__dirname, 'middleware'),
}

/** Define servers */
const app = Express()
const server = http.createServer(app)
const parser = new APIParser(app, config)

parser.parseFromFile('config.yaml')
parser.load()

server.listen(8000, () => {
  console.log('[SERVER][INFO] Server started on port 8000')
})

And finnaly create middlewares and controllers

// middleware/authenticate.js
export default function authenticate(req, res, next) {
  // Doing stuff here
  next()
}

// [...]

// controller/user.js
export function getUser({params}) {
  return {
    message: `User #${params.id} has been requested !`
  }
}

// controller/deleteUser.js
export default function deleteUser({params}) {
  return {
    message: `User #${params.id} has been deleted !`
  }
}

Philosophy

The package philosophy is to provide small a smart configuration parser that load an application into a router. The package must be robust, fast (in execution time way), and fast (in writting code way).

The key words are :

• robust
• modularity
• easy-to-use
• light

It does not depends on any specific router, but we recommand to use with Express.

Tests

The library provide tests, and every commit is checked by using Github Actions : .

If you want to run the tests by yourself, please follow this commands :

git clone git@github.com:vigilock/fast-custom-router.git
cd fast-custom-router
npm install
npm test
