News Reader

This document shows how to implement a simple news reader using Ray. The reader consists of a simple Vue.js frontend and a backend consisting of a Flask server and a Ray actor. View the code for this example.

To run this example, you will need to install NPM and a few python dependencies.

pip install atoma
pip install flask

To use this example you need to

• In the ray/examples/newsreader directory, start the server with python server.py.
• Clone the client code with git clone https://github.com/ray-project/qreader
• Start the client with cd qreader; npm install; npm run dev
• You can now add a channel by clicking "Add channel" and for example pasting http://news.ycombinator.com/rss into the field.
• Star some of the articles and dump the database by running sqlite3 newsreader.db in a terminal in the ray/examples/newsreader directory and entering SELECT * FROM news;.
