sqlx-news-example

This is an example command-line app to combine the use of Postgres, sqlx and NewsAPI. The main idea is to query news articles from NewsAPI, and dump it to a Postgres database with full type safety.

Basic Usage

Populate .env based on .env.example. You can get the NewsAPI API token by signing up to NewsAPI for free.

# Spin up a Postgres instance in the background:
docker-compose down -v && docker-compose up -d

# Health check
cargo run -- --app health-check

# Fetch and dump articles
cargo run -- --app fetch-and-dump-articles --query "dogecoin elon musk"

# Print 10 random articles
cargo run -- --app print-articles --limit 10
