How to build a RESTful API with Docker, PostgreSQL, and go-chi

Go-chi is a lightweight router library designed for building modular HTTP services in Go, offering flexibility without the complexity of a full web framework. The tutorial guides users through creating a containerized bucket list API using Go-chi, PostgreSQL, and Docker, detailing how to set up endpoints for adding, retrieving, updating, and deleting items. It outlines the necessary prerequisites, such as Go, PostgreSQL, Docker, and basic knowledge of these technologies, and describes the project's directory structure, including key files like Dockerfile, docker-compose.yml, and environment variable files. The guide also covers database setup using golang-migrate for managing migrations, structuring Go models for database interaction and JSON rendering, and implementing route handlers with chi's routing features. The tutorial concludes by demonstrating how to test the API using Docker and cURL, providing step-by-step instructions and sample commands to interact with the API's endpoints, and offers the complete source code on GitLab for further exploration.
