go install github.com/swaggo/swag/cmd/swag@latest

Database

This project now uses goose for DB migrations.

Install via brew install goose on a mac, or install via golang with command go install github.com/pressly/goose/v3/cmd/goose@latest

Create a new up/down migration file with this command

goose -dir db/migrations sqlite3 ./db.sqlite3 create init sql

sqlc generate

HTML templates

Run templ generate -path ./components to generate code based on template files

Documentation

Run swag init --exclude "pkg.mod,pkg.build,pkg.tools" -o server/router/docs

Database Configuration

By default the app uses SQLite and creates/opens db.sqlite3. You can opt into PostgreSQL by setting environment variables:

DB_DRIVER: sqlite (default) or postgres
DB_URL: SQLite file path/DSN or PostgreSQL DSN

Examples:

# SQLite (default)
DB_DRIVER=sqlite DB_URL=./db.sqlite3

# PostgreSQL
DB_DRIVER=postgres DB_URL=postgres://user:pass@localhost:5432/vctp?sslmode=disable

PostgreSQL migrations live in db/migrations_postgres, while SQLite migrations remain in db/migrations.

Snapshot Retention

Hourly and daily snapshot table retention can be configured with environment variables:

HOURLY_SNAPSHOT_MAX_AGE_DAYS (default: 60)
DAILY_SNAPSHOT_MAX_AGE_MONTHS (default: 12)
