Secure player accounts with a database in Your Godot 4 + Go MMO. We will be implementing user authentication with Go sqlc to manage accounts and secure your MMO. This video will cover everything from setup to integration and security. We'll use SQLite, a lightweight yet powerful database engine ideal for small-to-medium projects. While SQLite is our choice for this series, the setup will be flexible enough to swap in alternatives like PostgreSQL or MySQL if needed. We have made the choice to not use an ORM (Object-Relational Mapping) library for this project. While ORMs can be useful, they can also be overly complex and frankly overkill for a project of this size. We will be hand-writing our SQL queries, and compiling them to Golang code with sqlc. This will give us total control over the database and give us full visibility into what is happening. If you don't have experience with SQL, don't worry! We will be writing simple queries that are easy to understand, and I will explain what each query does.
