Details
The article discusses how serverless databases like Neon Postgres have changed the way small projects can be shipped, eliminating the need for connection pooling and idle server costs. Neon Postgres provides a full Postgres database with a generous free tier, allowing developers to set up a global leaderboard for their side project in just a few steps. The article outlines the schema design, including an attempts table to store submission details and a stats table to hold aggregate counters. Ranking is calculated by counting the number of attempts with a lower deviation than the user's. For rate limiting, the article suggests an in-memory approach suitable for a side project with moderate traffic. Finally, the article highlights that the entire infrastructure cost for a global multiplayer game can be zero, thanks to Neon Postgres's free tier.
