@webshift

Goals

• Enhance React based SPAs (Single Page Applications) with SSR (server side rendering)
• Enhance frontend micro-services architecture

Install Dependencies

• Nodejs

Quick Start

Create webshift project

npm init webshift@latest <working-dir>

==>

../
├── src/
│   ├── ...
│   ├── App.js
├── package.json
├── webshift.config.js

Start Development

• Bundles ./src/App.js into memory with webpack-dev-middleware
• Provides Hot Module Replacement with webpack-hot-middleware

npm start

Production Build

• Bundles ./src/App.js into the ./build folder
• Optimizes artifacts and includes hashes into filenames

npm run build && npm run build:start

==>

../
├── build/
│   ├── analyse/                        <-- bundle details (size, dependencies)
│   ├── public/                         <-- www folder

Code Splitting with @loadable

Split client code for better web performance

import { Route, Switch } from 'react-router';
import { Link } from 'react-router-dom';
import loadable from '@loadable/component';

export default (props) => {
    const Welcome = loadable(() => import('./Welcome'));
    const Aboutus = loadable(() => import('./Aboutus'));
    const Error = loadable(() => import('./Error'));
    
    return (
        <Layout>
            <Link to="/">Welcome</Link>
            <Link to="/about">About Us</Link>
            <Switch>
                <Route path={ '/' } component={ Welcome } />
                <Route path={ '/about' } component={ Aboutus } />
                <Route component={ Error } />
            </Switch>
        </Layout>
    );
};

useServerSideEffect()

Fetching data on the server.

Fetch library should be universal e.g. axios

import axios from 'axios';
import { useServerSideEffect } from 'webshift';

const MyComponent = () => {
    const [data, error] = useServerSideEffect('key', () => {
        return axios.get("https://myapi.example.com").then((res) => res.data);
    }, []);

    return <div>{data.title}</div>;
};

useLogger()

import { useLogger } from 'webshift';

const MyComponent = () => {
    const logger = useLogger();
    logger.verbose({message: "[Render]", meta: { component: 'MyComponent'}});

    return <div>Some Text</div>;
};

Advanced Build Configuration

Edit ./webshift.config.js to customise bundle

module.exports = {
    common: {
        resolve: {
            alias: {
                '@app': `${ process.cwd() }/src/App.js`,
            },
        },
    },
    client: {
        resolve: {
            alias: {
                '@logger': `${__dirname}/client/logger.js`,
            },
        },
        externals: [
            "react",
            "react-dom",
            "react-router",
            "react-router-dom",
        ],
    },
    server: {
        resolve: {
            alias: {
                '@render': `${__dirname}/server/render.js`,
                '@core': `${__dirname}/server/core.js`,
                '@document': `${__dirname}/server/document.js`,
                '@logger': `${__dirname}/server/logger.js`,
            },
        },
