go-postgres-api

Simple Golang API using docker to provide a Postgres DB & redis for endpoint caching.

Usage:

To run in development mode with hot reload: make run-dev

To run a production build: make run-prod

Requirements

• Docker
• Docker Compose

Working Routes:

GET http://localhost:8080/api/products
GET http://localhost:8080/api/products/:id

TODO:

• Add more logging
• Implement redis endpoint caching
• Use sync.Pool for db conns
• Finish Product CRUD utility
• Add unit tests
• Add benchmark tests & profile performance

Performance test with endpoint caching:

I've run a small load test on the initial API using vegeta, results shown below.

echo 'GET http://localhost:8080/api/products' | vegeta attack -rate 300 -duration 10s | vegeta report -reporter text
