gitly.dev
gitly.dev is a web application that takes in input the name of a GitHub repository and outputs a score that tells how active a GitHub repository is. I often found myself doing this sort of checks manually, thus I thought it would have been nice to automatize the whole process.
This is a project written for fun in TypeScript, Go and plain JavaScript with React for the front-end.
Since it has been written for fun, over-engineering was the rule.
Architecture
The actors involved are:
- a web application serving web pages written in JavaScript using Next.js (found inside the
appfolder) - APIs (TypeScript + Node.js) (found inside the
apifolder) - a processing daemon written in Go (found inside the
processingfolder) - Redis - used as cache and PubSub system
Both the APIs and the processing Go applications are subscribed to the same Redis PubSub channels. When the web application sends a request to calculate the score for a particular repository:
- APIs: publish a message inside the channel with a particular id that identifies the request
- APIs: record a callback for that particular request, waiting for a response
- Processing daemon: calculates the score inside a goroutine and publishes it inside the channel
- APIs: return the result to the client
I hope to publish a sequence diagram soon.
How to get better
Parallelize requests inside api/app.ts with Promise.all(), at the moment they are serial for simplicity.
Right now, as you can see in docker-compose.production.yml each node has its own Redis, this should be externalized and shared, especially if traffic will be high (unlikely).
