What you'll learn in this TypeScript course

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.

This course was great. I feel very accomplished after writing this typescript application which fetches data from the internet and stores it in a database.

A great hands-on project for practicing TypeScript, PostgreSQL, and SQL. I enjoyed building the CLI step by step and applying database relationships, RSS feeds, and aggregation in a real project.

terminal app that pulls blog posts from the internet and saves them in a database so I can read them later. Along the way I learned how to talk to a database, run background jobs on a timer, and keep user/login logic clean without copy-pasting the same checks everywhere. Super awesome seeing how everything is chained together bringing order and funcitonality through variety of queries.
