The smallest setup would be bit-bundler with no options and bundle a file.
$ npm install @bit/bundler -g
$ bitbundler --src src/main.js --dest dist/out.js
That's it. That will bundle
src/main.js and put the result in
dist/out.js. But this is not really as interesting as it could be. In the next section we are going to setup a couple of loader plugins to enable features such as transpilation and linting.
