Welcome to the Blog Aggregator
We're going to build an RSS feed aggregator in TypeScript! We'll call it "Gator", you know, because aggreGATOR 🐊. Anyhow, it's a CLI tool that allows users to:
- Add RSS feeds from across the internet to be collected
- Store the collected posts in a PostgreSQL database
- Follow and unfollow RSS feeds that other users have added
- View summaries of the aggregated posts in the terminal, with a link to the full post
RSS feeds are a way for websites to publish updates to their content. You can use this project to keep up with your favorite blogs, news sites, podcasts, and more!
Prerequisites
The project assumes that you're already familiar with TypeScript and SQL databases.
Learning Goals
- Learn how to integrate a TypeScript application with a PostgreSQL database
- Practice using your SQL skills to query and migrate a database (using drizzle, a lightweight tool for type-safe SQL in TypeScript)
- Learn how to write a long-running service that continuously fetches new posts from RSS feeds and stores them in the database
Assignment
Before we dive into the code, let's make sure you have everything you'll need on your machine.
22.15.0
This allows you to simply type nvm use in your CLI while in the root of your project to activate the correct version of node! You may get an installation command to run if you don't yet have that version of node, but it's just another one-liner.
Check to make sure you've activated the correct version of node by typing:
node --version
# Prints: v22.15.0
Run and submit the CLI tests.
The Boot.dev CLI requires you to be signed in to submit your solution!
Copy/paste one of the following commands into your terminal:
Run
bootdev run 4d624835-9830-4ca6-bfbb-280112f64baf
Submit
bootdev run 4d624835-9830-4ca6-bfbb-280112f64baf -s
Run the CLI commands to test your solution.
- echo "bootdev cli is ready!"
- Expecting exit code: 0
- Expecting stdout to contain all of:
- bootdev cli is ready!
- node -v
- Expecting exit code: 0
- npm -v
- Expecting exit code: 0
Using the Bootdev CLI
The Bootdev CLI is the only way to submit your solution for this type of lesson. We need to be able to run commands in your environment to verify your solution.
You can install it here. It's a Go program hosted on GitHub, so you'll need Go installed as well. Instructions are on the GitHub page.
