Go Backend Template

A simple opinionated Go web app template.

The intention for this project is to work as a template, where the developer should be able to concentrate right away on the business problem and not the usual dev environment and auth wiring. The focus is intentionally on mainly functionality, so the UI is bare-bones.

Features

Session-based authentication with a sliding expiration
Argon2 password hashing
PostgreSQL database
CORS support
Request logging middleware
Native Go HTTP server (no external frameworks)
HTMX for interactivity

Requirements

Go 1.24+
PostgreSQL
goose for migrations
sqlc for generating type-safe queries from SQL

air for live reload (optional)

go install github.com/pressly/goose/v3/cmd/goose@latest
go install github.com/sqlc-dev/sqlc/cmd/sqlc@latest
go install github.com/air-verse/air@latest

Setup

Copy environment variables:
```
cp .env.example .env
```
Update .env with your database credentials (both the DB_* and GOOSE_* values).
Install dependencies:
```
go mod tidy
```
Run database migrations:
```
./scripts/goose.sh up
```

Run the server:

air              # live reload, or:
go run ./cmd

Migrations

goose.sh loads .env and passes through to goose (up, down, status, ...). Create a new migration with:

./scripts/goose-create.sh add_widgets

SQLC

Query codegen is configured in sqlc.yaml (engine postgresql, schema read from migrations/). Add .sql files under internal/database/queries/ and run sqlc generate to emit typed accessors into internal/database/sqlc/.

Database Schema

user_auth - User accounts with Argon2 password hashes
user_session - User sessions with SHA-256 hashed token secrets
