Deprecated in favor of @visma/cra-template-craco-super-template

@arnosaine/react-scripts

A tiny fork of react-scripts. Allows using Babel config and modifying the built-in Webpack config without ejecting.

Usage

Create new project

npx create-react-app --scripts-version @arnosaine/react-scripts my-app

Replace official CRA in an existing project

npm install @arnosaine/react-scripts
npm uninstall react-scripts

Use other templates

npx create-react-app --scripts-version @arnosaine/react-scripts --template @arnosaine/cra-template my-app

Babel config

Add Babel Config File, for example .babelrc.json. It is merged to the built-in config:

{
  "presets": ["@postinumero/experimental"]
}

Webpack config

Add webpack.config.js. Export a function that takes env and returns a function. Returned function takes the built-in Webpack config that can be modified and finally returned. See webpack.config.js in react-scripts for the config structure.

ES module syntax is supported.

Examples

Add dotenv-webpack plugin

import Dotenv from 'dotenv-webpack';

export default _env => config => {
  config.plugins.push(
    new Dotenv({
      safe: true,
      systemvars: true,
    })
  );

  return config;
};

Add shared module resolution

export default _env => config => {
  config.resolve.modules.push('shared');

  return config;
};

Edit output path

import path from 'path';
import paths from '@arnosaine/react-scripts/config/paths.js';

paths.appBuild = path.resolve(process.cwd(), 'other/output/path');

export default _env => config => {
  return config;
};

Add .properties loader

import path from 'path';

export default env => config => {
  const { oneOf: rules } = config.module.rules.find(({ oneOf }) => oneOf);

  // Last rule should be original file-loader fallback. Insert new rules just
  // before last rule.
  rules.splice(rules.length - 2, 0, {
    test: /\.properties$/,
    use: 'properties-loader',
  });

  return config;
};

Transpile JSX and other syntax in node_modules

import path from 'path';
import paths from '@arnosaine/react-scripts/config/paths.js';

export default env => config => {
  const babelLoaderAppSrc = config.module.rules
    .find(({ oneOf }) => oneOf)
    .oneOf.find(({ include }) => include === paths.appSrc);

  babelLoaderAppSrc.include = [
    babelLoaderAppSrc.include,
    path.join(process.cwd(), 'node_modules/some-package'),
  ];

  return config;
};

Add Webpack alias fields

Useful when developing packages with npm link.

function addAlias(config, ...dependencies) {
  for (const dependency of dependencies) {
    config.resolve.alias[dependency] = require.resolve(dependency);
  }

  return config;
}

export default env => config => {
  // ...

  return addAlias(config, 'react', 'react-dom');
};
