What is @craco/craco?

@craco/craco is a configuration layer for Create React App (CRA) that allows you to customize the default CRA configuration without ejecting. It provides a way to override the Webpack configuration, Babel configuration, and other settings in a more flexible and maintainable way.

What are @craco/craco's main functionalities?

Webpack Configuration Override

This feature allows you to override the default Webpack configuration provided by Create React App. In this example, the CracoLessPlugin is used to customize the primary color in a LESS file.

const CracoLessPlugin = require('craco-less');

module.exports = {
  plugins: [
    {
      plugin: CracoLessPlugin,
      options: {
        lessLoaderOptions: {
          lessOptions: {
            modifyVars: { '@primary-color': '#1DA57A' },
            javascriptEnabled: true,
          },
        },
      },
    },
  ],
};

Babel Configuration Override

This feature allows you to override the default Babel configuration. In this example, the Babel plugin for decorators is added to the configuration.

module.exports = {
  babel: {
    plugins: [
      ['@babel/plugin-proposal-decorators', { legacy: true }],
    ],
  },
};

ESLint Configuration Override

This feature allows you to override the default ESLint configuration. In this example, the 'no-console' rule is turned off.

module.exports = {
  eslint: {
    enable: true,
    mode: 'extends',
    configure: {
      rules: {
        'no-console': 'off',
      },
    },
  },
};
