Repo demoing yarn workspaces + webpack live builds from src

• Yarn workspaces - pkg-one has a dependency on pkg-two, and running yarn at the top level symlinks them together, while also installing other non-symlink dependencies from npm.
• Webpack live builds from src - webpack is configured to prefer the /src directory over the dist directory. This means any changes to pkg-two/src/index.js get picked up by webpack automatically which triggers a rebuild of pkg-one.

Demo

Build demo

Just run yarn at the top level (make sure you are using yarn 1.3 or later) and it'll run webpack and execute the output bundle to show 'Hello world'

Live updates

To see the live rebuild getting triggered:

# start webpack in watch mode:
cd packages/pkg-one && yarn dev

# in a new terminal:
echo '//' >> packages/pkg-two/src/index.js # to trigger webpack
