cuttle

Opinionated database toolkit for Go.

Work in progress: This is incomplete and does not fully function yet!

Features:

• TODO
• Transactions
• Batches
• Repository code generator

Codegen

Cuttle optionally includes a repository pattern code generator:

-- :cuttle version=1
-- :repository name=UsersRepository dialects=sqlite,postgres

-- :query name=InsertUser mode=exec
-- :arg name=username type=string
-- :arg name=password type=string
-- :arg name=role type=string
-- :dialect name=sqlite
INSERT INTO users (username, password, role)
VALUES (?1, ?2, ?3);
-- :dialect name=postgres
INSERT INTO users (username, password, role)
VALUES ($1, $2, $3);

Produces:

package main

import (
	"context"
	"github.com/csnewman/cuttle"
)

type UsersRepository interface {
	InsertUser(
		ctx context.Context,
		tx cuttle.WTx,
		username string,
		password string,
		role string,
	) (int64, error)

	InsertUserAsync(
		tx cuttle.AsyncWTx,
		username string,
		password string,
		role string,
		callback cuttle.AsyncHandler[int64],
	)
}

// [...]
func NewUsersRepository(dialect cuttle.Dialect) (UsersRepository, error) {
// [...]

Why not use database/sql

TODO

Drivers

Behind the scenes, cuttle uses the following libraries:

Database	Library
Postgres	github.com/jackc/pgx
SQLite	github.com/tailscale/sqlite
Other	TODO (wrapper around database/sql)
