This is a project I did to get the minimal tooling up and running to support React and Redux development, following Pete Hunt's awesome webpack setup tutorial.
First, install webpack if it’s not available:
npm install -g webpack
Next, run npm install to install all dependencies.
Then, you can run npm test to run some (unbelievably trivial) tests.
Finally, you can run npm start to build the application, serve it on port 4000, and auto-reload when code changes.
You can run also webpack to compile all JSX, etc. into the index.js file. Open index.html in the browser of your choice, and it all should work.
There are a lot of other webpack command line options, see the webpack tutorial above.
