Forked from https://github.com/Nargonath/cra-build-watch in order to work with newer react-scripts

Disclaimer

The builds resulting from this script are NOT for production environment. They lack various optimizations.

This script is meant as a temporary workaround for create-react-app project based until this feature is built-in into react-scripts. See create-react-app#1070.

This script is inspired by other work related such as: https://gist.github.com/jasonblanchard/ae0d2e304a647cd847c0b4493c2353d4.

Why do I need this?

As of now (20/04/2018), create-react-app (more precisely react-scripts) does not allow development builds to be written to the disk because it uses webpackDevServer to serve your build files and folders (for good reasons). The problem is that in some cases you need to have these files written to the disk i.e:

• Developing browser extensions using React.
• Incorporating your React application into an existing application.
• Serving your React app with a dedicated backend.

Installation

Add it to your project using npm:

npm install -D cra-build-watch-js

or using yarn:

yarn add -D cra-build-watch-js

Usage

Add a new script into your package.json:

{
  "scripts": {
    "watch": "cra-build-watch"
  }
}

Run that script:

npm run watch

with Yarn:

yarn watch

Configuration

By default the script will generate everything into build/ at your project root and remove the public path from webpack's configuration.

If those defaults do not work for you, the script accepts some arguments:

• -b|--build-path: expects either an absolute or relative path. If a relative path is given it will be prefixed by your project root path.
  • default: yourProjectRoot/build.
• -p|--public-path: expects a relative URL where / is the root. If you serve your files using an external webserver this argument is to match with your web server configuration. More information can be found in webpack configuration guide.
  • default: "".
• -v|--verbose: display webpack build output.
