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.
|
|
|
|
.. code-block:: bash
|
|
|
|
pip install atoma
|
|
pip install flask
|
|
|
|
|
|
To use this example you need to
|
|
|
|
* In the ``ray/doc/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/doc/examples/newsreader``
|
|
directory and entering ``SELECT * FROM news;``.
