|
|
|
Go module `github.com/ncruces/go-sqlite3` is a `cgo`-free [SQLite](https://sqlite.org/) wrapper.\
|
|
It provides a [`database/sql`](https://pkg.go.dev/database/sql) compatible driver,
|
|
as well as direct access to most of the [C SQLite API](https://sqlite.org/cintro.html).
|
|
|
|
It wraps a [Wasm](https://webassembly.org/) [build](embed/) of SQLite,
|
|
and uses [wazero](https://wazero.io/) as the runtime.\
|
|
Go, wazero and [`x/sys`](https://pkg.go.dev/golang.org/x/sys) are the _only_ runtime dependencies.
|
|
|
|
### Getting started
|
|
|
|
Using the [`database/sql`](https://pkg.go.dev/database/sql) driver:
|
|
```go
|
|
|
|
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`](https://pkg.go.dev/github.com/ncruces/go-sqlite3)
|
|
wraps the [C SQLite API](https://sqlite.org/cintro.html)
|
|
([example usage](https://pkg.go.dev/github.com/ncruces/go-sqlite3#example-package)).
|
|
- [`github.com/ncruces/go-sqlite3/driver`](https://pkg.go.dev/github.com/ncruces/go-sqlite3/driver)
|
|
provides a [`database/sql`](https://pkg.go.dev/database/sql) driver
|
|
([example usage](https://pkg.go.dev/github.com/ncruces/go-sqlite3/driver#example-package)).
|
|
- [`github.com/ncruces/go-sqlite3/embed`](https://pkg.go.dev/github.com/ncruces/go-sqlite3/embed)
|
|
embeds a build of SQLite into your application.
|
|
- [`github.com/ncruces/go-sqlite3/vfs`](https://pkg.go.dev/github.com/ncruces/go-sqlite3/vfs)
|
|
wraps the [C SQLite VFS API](https://sqlite.org/vfs.html) and provides a pure Go implementation.
|
|
- [`github.com/ncruces/go-sqlite3/gormlite`](https://pkg.go.dev/github.com/ncruces/go-sqlite3/gormlite)
|
|
provides a [GORM](https://gorm.io) driver.
|
|
|
|

|
|
### Caveats
|
|
|
|
This module replaces the SQLite [OS Interface](https://sqlite.org/vfs.html)
|
|
(aka VFS) with a [pure Go](vfs/) implementation,
|
|
which has advantages and disadvantages.
|
|
|
|
Read more about the Go VFS design [here](vfs/README.md).
|
|
|
|
### Testing
|
|
|
|
This project aims for [high test coverage](https://github.com/ncruces/go-sqlite3/wiki/Test-coverage-report).
|
|
It also benefits greatly from [SQLite's](https://sqlite.org/testing.html) and
|
|
[wazero's](https://tetrate.io/blog/introducing-wazero-from-tetrate/#:~:text=Rock%2Dsolid%20test%20approach) thorough testing.
|
|
|
|
Every commit is [tested](https://github.com/ncruces/go-sqlite3/wiki/Test-matrix) 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](https://github.com/sqlite/sqlite/blob/master/mptest/mptest.c).
|
|
|
|
### Performance
|
|
|
|
Perfomance of the [`database/sql`](https://pkg.go.dev/database/sql) driver is
|
|
[competitive](https://github.com/cvilsmeier/go-sqlite-bench) with alternatives.
|
|
|
|
The Wasm and VFS layers are also tested by running SQLite's
|
|
[speedtest1](https://github.com/sqlite/sqlite/blob/master/test/speedtest1.c).
|
|
|
