cd into the project directory and run npm install locally
Run npm link
Switch to any projects where you can install the Header
Add the header by running npm i bizly-header --save
In the project root (Layout.js) component add import Header from 'bizly-header'
Add react component in render method <Header />
Run npm start and go to your host app (Profile) and start it tools
Now any changes you make in the header component code will auto-reload the header (sometimes you need to refresh host app to see the changes, need to fix webpack watcher)
