Reeasy.js

Framework of React app with easy configuration. Support HMR and custom server. As simple as next.js.

Mostly ES6/React feature has be built in Reeasy.js. If you need more, just custom babel loader config.

How to use

Setup

Install it

npm i reeasy --save

and add a script to your package.json like this:

{
  "scripts": {
    "dev": "reeasy dev",
    "build": "reeasy build",
    "start": "reeasy start"
  }
}

create several necessary files:

index.html

<!DOCTYPE html>
<html>
  <head>
    <title>Welcome to reeasy.js!</title>
    <meta charset="UTF-8"/>
  </head>
  <body>
    <div id="root"></div>
    <script src="/bundle.js"></script>
  </body>
</html>

app.js

import React from 'react'

export default () => (
  <div>Welcome to reeasy.js!</div>
)

reeasy.config.js - (reeasy config file)

module.exports = {
  rootPath: './app.js',  //Entry file path of your app
  selector: '#root'      //Selector of element for rendering
}

finally run npm run dev and go to http://localhost:3000. To use another port, you can run npm run dev -- -p <your port here>.

Run in production mode

Build it first

npm run build

Start server

npm start

Start server using pm2

pm2 start npm -- start

Custom configuration

Custom configuration is specified in reeasy.config.js in root directory of your project

module.exports = {

  //Entry file path of your app, this field is required
  // rootPath: <your entry file path>,
  
  //Selector of element for rendering, default `div`
  //starting with `.` for class name (such as `.content`);
  //starting with `#` for id (such as `#root`);
  //otherwise for tag name (like `div`),
  selector: 'div',
  
  //Output directory for build, default `.dist`
  outDir: '.dist',

  //Output bundle name, default `bundle.js`  
  bundleName: 'bundle.js',

  //Public path for http server, default `/`  
  publicPath: '/',
  
  //Path of index html file, default `./index.html`
  indexHTML: 'index.html',
  
  //Custom webpack configuration
  webpack: (config, dev) => {
    //config: webpack configuration object
    //dev: boolean, is in development mode

    //your config here

    //return new config (important!)
    return config
  },

  //Custom babel-loader configuration  
  babelLoaderConfig: (config, dev) => {
    //config: babel-loader configuration
    //dev: boolean, is in development mode
    
    //your config here

    //return new config (important!)
    return config
  },

  ////Custom webpack-dev-middleware configuration  
  devMiddlewareConfig: (config) => {
    //config: webpack-dev-middleware configuration
    
    //your config here

    //return new config (important!)
    return config
  }
}

Cli

Reeasy cli usage

reeasy dev Run reeasy in development mode, with hot module replacement
reeasy build Build app in production mode
reeasy start Start in production mode, need run reeasy build first

options

-c, --config Custom reeasy configuration file
-p, --port Port to listen for http server
-w, --cwd Custom working directory

Custom server

First, add a server.js file in your project directory like this:

If you use http module directly

const http = require('http')
const reeasy = require('reeasy')

const app = reeasy({
  dev: process.env.NODE_ENV !== 'production'
})

app.prepare().then(middleware => {
  const server = http.createServer((req, res) => {
    middleware(req, res)
  })

  server.listen(3000, err => {
    if (err) throw err
    console.log('> Ready on http://localhost:3000')
  })
})

If you use express

const express = require('express')
const reeasy = require('reeasy')

const app = reeasy({
  dev: process.env.NODE_ENV !== 'production'
})

app.prepare().then(middleware => {
  const server = express()

  //define other middleware here

  server.use(middleware)

  server.listen(3000, err => {
    if (err) throw err
    console.log('> Ready on http://localhost:3000')
  })
})

If you use koa

const Koa = require('koa')
const reeasy = require('reeasy')

const app = reeasy({
  dev: process.env.NODE_ENV !== 'production'
})

app.prepare().then(middleware => {
  const server = new Koa()

  //define other middleware here

  server.use(middleware.koa())

  server.listen(3000, err => {
    if (err) throw err
    console.log('> Ready on http://localhost:3000')
  })
})

Then add a script to your package.json like this:

{
  "scripts": {
    "dev": "NODE_ENV=development node server.js",
    "build": "reeasy build",
    "start": "NODE_ENV=production node server.js"
  }
}

Finally start your project by npm scripts.

The reeasy API is:

reeasy(opts: object) Create reeasy instance

Supported options:

cwd (string) Current work directory, use process.cwd() as default
dev (bool) Whether to launch reeasy in dev mode, default false
conf (string) Custom reeasy configuration file path, if not set this option, use default configuration file path (reeasy.config.js in root directory)
