Build a Blog Aggregator in TypeScript

Build an RSS-powered TypeScript backend with a database, background work, and a real API shape.

Also available in:

go

What will you learn?

In this guided project you'll practice building a CLI in TypeScript, and you'll use production-ready database tools like PostgreSQL and Drizzle. This won't just be another CLI utility, but a service that has a long-running service worker that reaches out over the internet to fetch data from remote locations.

Chapter List

1
Config
Build a system for the CLI tool that allows users to get and set configuration values
2
Database
Set up Postgres and drizzle to allow your CLI application to store and retrieve data.
3
RSS
Build functions that will download and parse data from RSS feeds
4
Following
Add to the multiplayer features of the project by allowing users to follow other RSS feeds
5
Aggregate
Turn your CLI into a long running service that continously aggregates posts from RSS feeds.

The 2 unfinished steps in the aggregate chapter were a bit annoying, as it would have been nice to have some required tests also to see if the output i got was what was expected. Due to there not being tests the difficulty of those steps is also completely wrong as I am sure most people just click "yes" without actually doing it and thus making it seem the steps are a lot easier than they actually are. I personally found the scrape step harder than most of the other step

Good course for starting to use a Db and start bringing things learned so far together. Tip: AFTER completing a lesson, check the solution to help you better structure your code and enhance it. Enjoy!

Great project. Taxes the little grey cells with some novel coding. I'm not yet completely used to the TypeScript ways of doing things, so sometimes wished for a little extra in the way of hints; but I got there in the end and the achievement was worth it.
