emojitrack-gostreamer

Implementation of an API compatible server for the Emojitracker Streaming API Specification in Go.

Caveats

This was originally my first major Go project, so there may potentially still be some silly stuff left in the code here.

Pipeline Flow

Goroutines and channels make it just too much fun to think about things as flow diagrams. This is the essential pipeline for information flow in the main() function for the program.

Package sseserver

This program doesn't actually do too much beyond the pipeline flow above, as all of the SSE/HTTP server logic has been extracted into a handy modular package that should be usable for any generic SSE broadcasting. For that stuff, delve into the (freely licensed!) sseserver repo.

Development

A sandbox environment is provided to test via Docker Compose, using emojitrack/fakefeeder to simulate production traffic.

Simply run docker compose up and you'll have a local environment to test against, with the streamer exposed on port 8001. Try curl http://localhost:8001/subscribe/eps for example.

Production

Currently handled on Heroku, to add remotes manually after cloning the repository:

heroku git:remote --remote production emojitrack-gostreamer
heroku git:remote --remote staging emojitrack-gostreamer-staging

Simply git pushing to either will build and update.

Is it any fast?

Yes.:racehorse:
