Install

# install tsrx
npm i -S tsrx

# install dependencies
npm i -S react react-dom typescript

# install dev dependencies
npm i -D @types/react @types/react-dom

# install test utilities
npm i -D jest @testing-library/jest-dom @testing-library/react

Setup tsconfig

Extend base tsconfig.json from TSRX folder:

{
  "extends": "tsrx/tsconfig.json",
  "compilerOptions": {}
}

Setup the script configuration

Create a js file as example below to setup the scrips command with a mininal setup:

Ex.: react.config.js

const { DefaultConfig } = require('tsrx/tools');

module.exports = DefaultConfig({
  // port to be used in development
  // will be set in webpack-dev-server
  port: 8080,
  devServer: {
    // development server
    // will open the browser
    // as soon as the project
    // was compiled
    open: true,
  },
});

Using scripts

TSRX have methods to be used in scripts of the package.json.

Is better to set unique config file for each method:

{
  "scripts": {
    "start": "tsrx start ./react.config.js",
    "build": "tsrx build ./react.config.prod.js",
    "test": "tsrx test ./react.config.test.js"
  }
}

Advanced options

Ex.: react.config.js

const { DefaultConfig } = require('tsrx/tools');

module.exports = DefaultConfig({
  /**
   * Source path of application files
   * Default = src
   */
  sourcePath: 'src',

  /**
   * Source index file of the app.
   *
   * If not provided, the index file will be search
   * on the sourcePath with these extensions => js, jsx, ts, tsx
   */
  sourceFile: 'index.ts',

  /**
   * output path for the compiled bundle.
   *
   * default = 'dist'
   */
  outputPath: 'dist',

  /**
   * port to be used in development
   * will be set in webpack-dev-server
   */
  port: 8080,

  /**
   * hostname to be used in development
   * will be set in webpack-dev-server
   *
   * default = localhost
   */
  host: 'localhost',

  /**
   * object with all enviroments to be set in
   *  - node: thru process.env
   *  - html: thru <%= htmlWebpackPlugin.options.propertyName %>
   */
  env: {
    textExample: 'Comment from Node Enviroments',
    booleanValueExample: true,
    numericValueExample: 37,
    htmlExample: 'Comment from HTML Enviroment',
  },
});

Jest customization

In case, if your tests require specific Jest configuration, include jest property in your react.config.test.js:

module.exports = DefaultConfig({
  ...
  jest: {
    coverageThreshold: {
      global: {
        branches: 50,
        functions: 50,
        lines: 50,
      },
    },
    moduleNameMapper: {
      '@components/(.*)': '<rootDir>/src/components/$1',
      '@containers/(.*)': '<rootDir>/src/containers/$1',
      '@interfaces/(.*)': '<rootDir>/src/interfaces/$1',
      '@services/(.*)': '<rootDir>/src/services/$1',
    },
    updateSnapshot: true,
  },
});

DevServer customization

In case if is necessary to customize webpack-dev-server options, just include "devServer" in your react.config.test.js:

module.exports = DefaultConfig({
  devServer: {
    open: true,
    publicPath: '/',
    contentBase: path.join(__dirname, 'dist'),
  },
  ...
});

Webpack options customization

Any properties defined in this property will override TSREX config:

module.exports = DefaultConfig({
  webpack: (config, env) => {
    // set your own webpack config
    config.output.publicPath = '/';
  },
});

Module Federation

Shared modules from webpack 5 can be configured

module.exports = DefaultConfig({
  moduleFederationOptions: {
    name: 'app-name',
    shared: ['react', 'react-dom', 'react-router-dom'],
    filename: 'remoteEntry.js',
    exposes: {
      './App': `./src/App`,
    },
  },
});
