Basic setup of a React project

This is NOT a npm package intended for installation. So do NOT install it.

This is a basic setup of React with Babel, Webpack with minimum dependencies to get you started.

Get started

npx react-get-started my-app

Tips

If you don't like the browser auto-reloads every time you change the code, then add inline: false to devServer property in webpack.dev.js.

...
devServer: {
    compress: true,
    port: 5000,
    overlay: true,
    inline: false
}
...

Develop with Sass

npm i --save-dev sass sass-loader

In webpack.dev.js, add settings of plugins in rules.

rules: [
    ...,
    
    {
        test: /\.s[ac]ss$/i,
        use: [ 
            'style-loader',
            'css-loader',
            'sass-loader'
        ]
    }
]

Then, you can add paths of Sass files in your source code, e.g.

import React from 'react';
import './index.scss';

Add TypeScript

npm i --save-dev @babel/preset-typescript @types/node @types/react @types/react-dom ts-loader typescript

Update Webpack config

Add TypeScript loader

rules: [
    ...,
    
    {
        test: /\.tsx?$/,
        exclude: /node_modules/,
        use: 'ts-loader'
    },
    ...
]

Resolve file extensions

Add extensions with ts, tsx so when import TypeScript modules, you don't have to type .ts or .tsx.

resolve: {
    extensions: [".js", ".json", ".ts", ".tsx"],
},
modules: { 
    ... 
},

Quoted from Webpack official site

Using this will override the default array, meaning that webpack will no longer try to resolve modules using the default extensions.

Update entry with a tsx file, for example

entry: './src/index.tsx',
output: { 
    ... 
},    

Update .babelrc

{
  "presets": [
        ...,
        "@babel/preset-typescript"
    ]
}

Add tsconfig.json

Here is an example. Some adjustments may be required as per project's needs.

{
  "compilerOptions": {
    "target": "es5",
    "lib": [
      "dom",
      "dom.iterable",
      "esnext"
    ],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "react",
    "outDir": "./built"
  },
  "include": [
    "src"
  ]
}
