This example shows how to implement a simple news reader using Ray. The RSS
feed reader app consists of a simple
Vue.js frontend and a backend
consisting of a Flask server and a Ray actor. View the code for this
To run this example, you will need to install NPM and a few python dependencies.
pip install atoma pip install flask pip install flask-cors
Navigate to the
ray/doc/examples/newsreader directory and start the Flask server.
Clone the client code.
git clone https://github.com/ray-project/qreader
Start the client.
cd qreader; npm install; npm run dev
qreader is running, you can visit the dashboard which should open
once its running. If it fails to open on its own, you can visit it at
the url listed in the screen output.
You can now add a channel by clicking “Add channel”. For example, try
http://news.ycombinator.com/rss into the field.
Star some of the articles in the channel. Each time you star an article, you can see the Flask server responding in its terminal.
Now we will view our database. Navigate back to the
ray/doc/examples/newsreader directory. Access the database by running
sqlite3 newsreader.db in the terminal. This will start a sqlite session.
View all the articles in the
news table by running
SELECT * FROM news;.
