My Go Project

Personal learning project following the official Go tutorials, then expanded into a small full-stack web app (Gin + MySQL + Vue.js).

Structure

• greetings/ — Standalone Go module from the Create a Go module tutorial. Provides a Hello function with unit tests.
• hello/ — Consumer module from the Call your code from another module tutorial. Imports greetings via a local replace directive.
• my_app/ — Full-stack web application: Gin REST API backed by MySQL, with a plain HTML + Vue.js (CDN) front end for user login and CRUD management.

my_app overview

• Backend: Go + Gin router, MySQL via database/sql, bcrypt password hashing.
• Routes: user CRUD (/users), login/logout (/users/login), home/success/404 pages.
• Frontend: static HTML pages in client/, styled via a shared global.css, with Vue.js 3 (CDN build) for the login page's interactivity.

Go tutorials followed

1. Getting started
2. Create a module

   go mod init example.com/greetings
   

3. Call module code from another module

   go mod edit -replace example.com/greetings=../greetings
   go mod tidy
   

4. Add a test

   go test -v
   

5. Compile and install
   • go build compiles the package and its dependencies but does not install the result.
   • go install compiles and installs the package.
