what is this?

gator is a command-line RSS reader written in Go. it fetches feeds, stores them in a Postgres database and provides commands to manage feeds and read posts.

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

why?

i'm learning go because i need it for 95 check it out

• learning how to integrate a Go application with a PostgreSQL database
• practicing SQL to query and migrate a database (using sqlc and goose)
• learning how to write a long-running service that continuously fetches new posts from RSS feeds and stores them in the database

pre-requisites

• download and install Go
• verify the installation:

go version

• start Postgres and create a database (name it gator)
• install the Gator CLI via go install or clone this project and use go build

running this app will create a hidden file named .gatorconfig.json in your home directory. this is used to track the username you provide (or change it) and the database URL.
