react-ssr-starter

This is a boilerplate inspired CRA. Designed with high scalability, an offline-first foundation, and a focus on performance and best practices.

Prerequisites

• Node.js: ^14.17.0 or >=16.0.0

Getting Started

git clone https://github.com/htdangkhoa/react-ssr-starter

yarn install # or npm install

yarn dev # or npm run dev

Highlight

Using SWC will give build times 1.5x faster for the server and 2.2x for the client instead of using Babel.

Scripts

Environment Variables

Your project can consume variables declared in your environment as if they were declared locally in your JS files. By default you will have NODE_ENV defined for you, and you can define any other variables that you want but for the React app, your variables name must be have REACT_APP_ prefix.

WARNING: Do not store any secrets (such as private API keys) in your React app!

Environment variables are embedded into the build, meaning anyone can view them by inspecting your app's files.

To define permanent environment variables, create a file called .env in the root of your project:

# For node
PRIVATE_CODE=123456

# For React app
REACT_APP_NOT_SECRET_CODE=abcdef

NOTE: You need to restart the development server after changing .env files.

What other .env files can be used?

• .env: Default.
• .env.local: Local overrides. This file is loaded for all environments except test.
• .env.development, .env.test, .env.production: Environment-specific settings.
• .env.development.local, .env.test.local, .env.production.local: Local overrides of environment-specific settings.

Or you can add custom .env path in webpack/webpack.config.base.js:

const DotenvWebpackPlugin = require('./plugins/dotenv-webpack-plugin');

// webpack config
{
  ...,
  plugins: [
    ...,
    new DotenvWebpackPlugin({
      path: './custom-env',
      isWeb: true|false,
    }),
  ],
}

Please refer to the dotenv documentation for more details.

Expanding Environment Variables In .env

Expand variables already on your machine for use in your .env file (using dotenv-expand).

For example, to get the environment variable npm_package_version:

REACT_APP_VERSION=$npm_package_version
# also works:
# REACT_APP_VERSION=${npm_package_version}

Or expand variables local to the current .env file:

DOMAIN=www.example.com
REACT_APP_FOO=$DOMAIN/foo
REACT_APP_BAR=$DOMAIN/bar

NOTE: Support Google Search Console verification code with GOOGLE_SITE_VERIFICATION environment variable.

Configurations

Basic

You can store your configurations in src/configs/client.js for client-side, src/configs/server.js for server-side. src/configs/constants.js is for constants.

You can access the correct configuration with:

import configs from 'configs/client'; // for client-side
import configs from 'configs/server'; // for server-side
import constants from 'configs/constants';

// ...

Advanced

You can adjust various development and production settings by setting environment variables in your shell or with .env.

Note: You do not need to declare REACT_APP_ before the below variables as you would with custom environment variables.

Adding Styles

The starter supports CSS, SASS and CSS modules is auto enabled for all files the [name].module.* naming convention. I use PostCSS plugin to parse CSS and add autoprefixer to your stylesheet. You can access your stylesheet with two ways.

/* custom button style */

.Button {
  padding: 20px;
}

With CSS modules

import styles from './styles.module.scss';

function Button() {
  return <div className={styles.Button} />;
}

Without CSS modules

import './styles.scss';

function Button() {
  return <div className='Button' />;
}

You can also add the vendor CSS frameworks or global styles, just import it through the src/client/app/index.jsx file (app root component). For example:

import 'bootstrap/dist/css/bootstrap.min.css';
import '<your-global-styles>.css';

function App() {
  // ...
}

Adding Images, Fonts, and Files

With webpack, using static assets like images and fonts works similarly to CSS.

You can import a file right in a JavaScript module. This tells webpack to include that file in the bundle. Unlike CSS imports, importing a file gives you a string value. This value is the final path you can reference in your code, e.g. as the src attribute of an image or the href of a link to a PDF.

To reduce the number of requests to the server, importing images that are less than 10,000 bytes returns a data URI instead of a path. This applies to the following file extensions: bmp, gif, jpg, jpeg, and png. SVG files are excluded for sprite. You can control the 10,000 byte threshold by setting the IMAGE_INLINE_SIZE_LIMIT environment variable.

Here is an example:

import React from 'react';
import logo from './logo.png'; // Tell webpack this JS file uses this image

console.log(logo); // /70a4f6b392fa19ff6912.png

function Header() {
  // Import result is the URL of your image
  return <img src={logo} alt='Logo' />;
}

export default Header;

This ensures that when the project is built, webpack will correctly move the images into the build folder, and provide us with correct paths.

This works in CSS too:

.Logo {
  background-image: url(./logo.png);
}

Adding SVGs

One way to add SVG files was described in the section above. You can also import SVGs directly as React components. You can use either of the two approaches. In your code it would look like this:

import { ReactComponent as Logo } from './logo.svg';

function App() {
  return (
    <div>
      {/* Logo is an actual React component */}
      <Logo />
    </div>
  );
}

Generators

Usage

• npm

  npm run gen component "<component_name>"
  
  npm run generate component "<component_name>"

• Yarn

  yarn gen component "<component_name>"
  
  yarn generate component "<component_name>"

Example

yarn gen component "hello world"

# or npm run gen component "hello world"

Output: /src/client/components/HelloWorld/index.jsx will be generated. /src/client/components/HelloWorld/__tests__/index.test.jsx will be generated if you want add the unit testing.

Custom

You can add template in generators directory, please read more at plopjs.
