# MySQLite
A Go library that provides a convenient wrapper around SQLite with additional functionality for database management, migrations, and transactions.
## Features
- Simple and intuitive SQLite database connection management
- Thread-safe database operations with built-in locking mechanism
- Support for database migrations
- Transaction management
- Built on top of [zombiezen.com/go/sqlite](https://pkg.go.dev/zombiezen.com/go/sqlite)
## Installation
```bash
go get gitea.seeseepuff.be/seeseemelk/mysqlite
```
## Usage
### Opening a Database Connection
```go
import "gitea.seeseepuff.be/seeseemelk/mysqlite"
// Open an in-memory database
db, err := mysqlite.OpenDb(":memory:")
if err != nil {
// Handle error
}
defer db.Close()
// Open a file-based database
db, err := mysqlite.OpenDb("path/to/database.db")
if err != nil {
// Handle error
}
defer db.Close()
```
### Executing Queries
The library provides methods for executing SQL queries and managing transactions:
```go
// Execute a simple query
err := db.Query("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)").Exec()
// Use transactions
tx, err := db.BeginTransaction()
if err != nil {
// Handle error
}
// Perform operations within transaction
// ...
// Commit or rollback
err = tx.Commit() // or tx.Rollback()
```
### Database Migrations
The library includes support for SQL-based migrations. Migrations are SQL files stored in a directory and are executed in order based on their filename prefix:
1. Create a directory for your migrations (e.g., `migrations/`)
2. Add numbered SQL migration files:
```
migrations/
├── 1_initial.sql
├── 2_add_users.sql
├── 3_add_posts.sql
```
3. Embed the migrations in your Go code:
```go
import "embed"
//go:embed migrations/*.sql
var migrations embed.FS
// Apply migrations
err := db.MigrateDb(migrations, "migrations")
if err != nil {
// Handle error
}
```
Each migration file should contain valid SQL statements. The migrations are executed in order and are tracked internally to ensure they only run once.
## Requirements
- Go 1.24 or higher
