Summary

This repository contains my learnings from Alex Edwards' brilliant Let's Go book. While I have stuck quite closely with the project defined in the book, I have also made deviations and additions to: (1) further challenge myself, and (2) explore more of the popular packages used by the greater Go community.

Please consider this repository as a work-in-progress — there are more things I want to add and make changes to.

Deviations/Additions

1. I have added a Makefile adapted from a blog post by Alex Edwards to make running mundane commands quicker. Notably, the Makefile includes a command to run the project with live reloading which automatically reruns the development server whenever a code change is detected.
2. I have added a package.json file that includes Prettier and the prettier-plugin-go-template plugin for it that formats Go HTML templates. I find it quite difficult to maintain the templates otherwise due to the Go templating syntax.
3. I use the GoDotEnv package for reading .env files which I use for providing default configuration values, rather than hard-coding them.
4. I use the Chi library for routing instead of httprouter. Chi offers many benefits over httprouter like clean middleware chaining and route grouping while remaining stdlib compliant.
5. I use pgx rather than the standard database/sql. This is because I decided to use Postgres instead of MySQL (which Alex uses in the book). Additionally, pgx features performance benefits due to its focus on Postgres rather than SQL databases in general.
6. I have added metrics via Prometheus to get the codebase closer to a production-ready state. I visualise the metrics using Grafana Cloud.
