Features

• Typescript runtime
• server side rendering
• static assets serving

How to use

• install dependencies

  npm install react react-dom react-router-dom pux-react

• create app/controllers folder in your project

  mkdir -p app/controllers

• create your page index.tsx

  import * as React from "react";
  export default class Index extends React.Component<{}> {
    public static path = "/"; // This is react router format path
    public static title = "Index"; // This is document.title
   
    public render() {
      return <div>Hello Pux</div>;
    }
  }

• add script to package.json file

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

• run npm run dev to start the app, go to localhost:3000

Demo App

Go to demos/newsApp

Data fetching

import * as React from "react";
import { match as Match, Link } from "react-router-dom";
 
export default class Index extends React.Component<{}> {
  public static path = "/";
  public static getInitialProps(match: Match, query: {}) {
    return Promise.resolve({ hello: "world" });
  }
  public render() {
    return <div>Hello ${this.props.hello}</div>;
  }
}

getInitialProps(match: Match, query: any) will be executed on both server side and client and we defer the execution of render funtion until the promise is resolved.

static assets serving

Any files placed under app/public folder will be served as static assets.

sever specific code

  import * as React from "react";
  import { proxy } from "pux-react";
 
  export default class Index extends React.Component<{}> {
    ...
    @proxy
    public static readFile(fileName: string) {
      const fs = require('fs')
      return new Promise(function(resolve, reject){
        fs.readFile(fileName, null, (err, data) => {
            err ? reject(err) : resolve(data);
        });
      });
    }
 
    componentDidMount() {
      Index.readFile('fileName').then(data => {
        this.setState({data})
      });
    }
    render() {
      ...
    }
  }
 

Method decorated with proxy will be executed as regular function on the server side. However on the client, the arguments will be serialized as json and submitted as a RPC call to the server to let server handle the call, the response will again be serialized as json and return to the client

Run in production

npm install

npm start

This will start the app as a daemon process.
