NewsBlur

Get it on F-Droid Get it on Google Play

Features

  1. Shows the original site (you have to see it to believe it).
  2. Hides stories you don't want to read based on tags, keywords, authors, etc.
  3. Highlights stories you want to read, based on the same criteria.

Technologies

Server-side

  • Python 3.7+: The language of choice.
  • Django: Web framework written in Python, used to serve all pages.
  • Celery & RabbitMQ: Asynchronous queueing server, used to fetch and parse RSS feeds.
  • MongoDB, Pymongo, & Mongoengine: Non-relational database, used to store stories, read stories, feed/page fetch histories, and proxied sites.
  • PostgreSQL: Relational database, used to store feeds, subscriptions, and user accounts.
  • Redis: Programmer's database, used to assemble stories for the river, store story ids, manage feed fetching schedules, and the minuscule bit of caching that NewsBlur uses.
  • Elasticsearch: Search database, use for searching stories. Optional.

Client-side and design

  • jQuery: Cross-browser compliant JavaScript code. IE works without effort.
  • Underscore.js: Functional programming for JavaScript. Indispensable.
  • Backbone.js: Framework for the web app. Also indispensable.
  • Miscellaneous jQuery Plugins: Everything from resizable layouts, to progress bars, sortables, date handling, colors, corners, JSON, animations. See the complete list.

Prerequisites

* Docker
* Docker-Compose

Installation Instructions

  1. Run make nb to build Newsblur containers. This will set up all necessary databases, celery tasks, node applications, flask database monitor, NGINX, and a Haproxy load balancer.

  2. Navigate to:

     https://localhost
    

    Note: You will be warned that you are using a self signed certificate. In order to get around this warning you must type "thisisunsafe" as per https://dblazeski.medium.com/chrome-bypass-net-err-cert-invalid-for-development-daefae43eb12

  3. To change the domain from localhost, you'll need to change it in a few places:

  • Change NEWSBLUR_URL and SESSION_COOKIE_DOMAIN in newsblur_web/docker_local_settings.py
  • Change the domain in config/fixtures/bootstrap.json, or if you've already created a site, edit the Site.objects.all()[0] domain in the shell, which you can access with make shell
  • If you're using a custom subdomain, you'll also want to add it to ALLOWED_SUBDOMAINS in apps/reader/views.py

Making docker-compose work with your database

To make docker-compose work with your database, upgrade your local database to the docker-compose version and then volumize the database data path by changing the ./docker/volumes/ part of the volume directive in the service to point to your local database's data directory.

To make docker-compose work with an older database version, change the image version for the database service in the docker-compose file.

Contribution Instructions

  • Making Changes:

    • To apply changes to the Python or JavaScript code, use the make command.
    • To apply changes to the docker-compose.yml file, use the make rebuild command.
    • To apply changes to the docker/haproxy/haproxy.conf file, node packages, or any new database migrations you will need to use the make nb command.
  • Adding Python packages: Currently, the docker-compose.yml file uses the newsblur/newsblur_python3 image. It is built using the Dockerfile found in docker/newsblur_base_image.Dockerfile. Because of how the docker image is set up, you will need to create your own image and direct your docker-compose.yml file to use it. Please follow the following steps to do so.

    1. Add your new site-packages to config/requirements.txt.
    2. Add the following lines of code to your docker-compose.yml file to replace anywhere where it says image: newsblur/newsblur_python3
    build: context: . dockerfile: docker/newsblur_base_image.Dockerfile
    1. Run the make nb command to rebuild your docker-compose containers
  • Debugging Python

    • To debug your code, drop import pdb; pdb.set_trace() into the Python code where you would like to start debugging and run make and then make debug.
  • Using Django shell within Docker

    • Make sure your docker containers are up and run make shell to open the Django shell within the newsblur_web container.

Running unit and integration tests

NewsBlur comes complete with a test suite that tests the functionality of the rss_feeds, reader, and feed importer. To run the test suite:

`make test`

Running a performance test

Performance tests use the locust performance testing tool. To run performance tests via CLI, use make perf-cli users=1 rate=1 host=https://localhost. Feel free to change the users, rate, and host variables in the command to meet you needs.

You can also run locust performance tests using a UI by running make perf-ui and then navigating to http://127.0.0.1:8089. This allows you to chart and export your performance data.

To run locust using docker, just run make perf-docker and navigate to http://127.0.0.1:8089
