Migralite

Migralite is lightweight forward-only SQLite migration tool for Bun.

Key features:

• Simple *.sql files as migration scripts
• Forward-only ^1
• Runs on Bun
• CLI with sensible defaults, so there's no need to implement migration script
• Migration generator
• Version tracking — keeps track of applied migrations to prevent duplicate runs
• Migrations are wrapped in transactions by default

Usage

Installation

Add CLI tool to the Bun based project:

bun add -d migralite

And then used via package.json scripts:

{
  "scripts": {
    "db:migrate": "migralite --database ./path/to/db.sqlite"
  }
}

The tool could be used with bunx without adding it to the project:

bunx migralite --help

Available commands

Help

--help or -h — shows help in the terminal.

Example:

bunx migralite --help

Version

--version or -v — shows current version of the CLI tool.

Example:

bunx migralite --version

Database path

--database or -d — path to the SQLite database file.

Example:

bunx migralite -d ./db/main.sqlite

Migrations path

--migrations or -m — path to the folder with SQL migration scripts, by default it's ./migrations folder in the root of the project.

Example:

bunx migralite -d ./db/main.sqlite -m ./db/migrations

Migration file generation

--generate or -g — migration file generation mode. It accepts short summary of what migration script is doing to generate migration name. The summary is added as a comment to the migration script.

Example:

bunx migralite -g "Create users table"

This will create a migration file in ./migrations folder called ./migrations/20240815123456__create-users-table.sql.

Only this filename format is accepted by the migration tool. Anything else will result in error and migrations won't run.

Development

To install dependencies:

bun install

To run:

bun run index.ts

Please raise an issue first and let's discuss. This project is pretty much done, but I am still open for some sensible contributions.
