This is the demo app from my article on WebStreams with PureScript.
Install all packages first.
pulp dep install
npm i
Then build backend (foreign imports etc.) with
gulp
And the frontend (client demo in browser console) with
gulp build-demo
Run the demo with HapiJS via
npm start
and open your browser at http://localhost:8080
Open your browser's console to see the stream data flowing in.
