Go bindings to SQLite using wazero

Go module github.com/ncruces/go-sqlite3 is a cgo-free SQLite wrapper.
It provides a database/sql compatible driver, as well as direct access to most of the C SQLite API.

It wraps a Wasm build of SQLite, and uses wazero as the runtime.
Go, wazero and x/sys are the only runtime dependencies.

Getting started

Using the database/sql driver:

import "database/sql"
import _ "github.com/ncruces/go-sqlite3/driver"
import _ "github.com/ncruces/go-sqlite3/embed"

var version string
db, _ := sql.Open("sqlite3", "file:demo.db")
db.QueryRow(`SELECT sqlite_version()`).Scan(&version)

Packages

• github.com/ncruces/go-sqlite3 wraps the C SQLite API (example usage).
• github.com/ncruces/go-sqlite3/driver provides a database/sql driver (example usage).
• github.com/ncruces/go-sqlite3/embed embeds a build of SQLite into your application.
• github.com/ncruces/go-sqlite3/vfs wraps the C SQLite VFS API and provides a pure Go implementation.
• github.com/ncruces/go-sqlite3/gormlite provides a GORM driver.

Caveats

This module replaces the SQLite OS Interface (aka VFS) with a pure Go implementation, which has advantages and disadvantages.

Testing

This project aims for high test coverage. It also benefits greatly from SQLite's and wazero's thorough testing.

Every commit is tested on Linux (amd64/arm64/386/riscv64/ppc64le/s390x), macOS (amd64/arm64), Windows (amd64), FreeBSD (amd64), OpenBSD (amd64), NetBSD (amd64), illumos (amd64), and Solaris (amd64).

The Go VFS is tested by running SQLite's mptest.

Performance

Perfomance of the database/sql driver is competitive with alternatives.

The Wasm and VFS layers are also tested by running SQLite's speedtest1.
