Distributed Twitter Engine
A distributed engine for a twitter-like application using Phoenix/Elixir, with posts, hashtags, user-mentions, re-posts, and subscriptions.
Features
- The User model
- The Tweet model with support for hashtags and user-mentions.
- Subscribing to a user
- Subscribing to a hashtag
- Retweeting a tweet
- Querying tweets with a hashtag or mention
- The front-end (built using Vue.js) and the back-end (built using Phoenix) interact with each other via HTTP and a websocket connection between a client and the server.
- Global events (such as a user joining the system, or an hashtag being created) is broadcasted to all connected clients live via Phoenix channels.
- Client-specific payload such as tweets from users she/he has subscribed to, or with hashtags she/he has subscribed is only received by that client live via Phoenix channels.
- A simulation for more users performing more requests to the engine can be run in the background, which every client is able to interact with.
