kysely-ctl is the official command-line tool for Kysely. We strive to make it TypeScript-first, cross-platform (macOS, Linux, and Windows), cross-runtime (Node.js, Bun, and Deno), and cross-module system (ESM and CommonJS) compatible. We also aim to have feature parity with Knex.js's CLI.

Note

This is a work in progress. Please report any issues you encounter or suggest any ideas you have in the issues section or in kysely's discord server.

Install

Prerequisites:

kysely-ctl requires kysely >= 0.18.1 to be installed.

Node.js:

npm i -D kysely-ctl

or:

yarn add -D kysely-ctl

or:

pnpm add -D kysely-ctl

Bun

bun add -D kysely-ctl

Deno

Add kysely-ctl to your package.json:

{
  ...
  "scripts": {
    ...
    "kysely": "kysely", // allows running commands with `deno task kysely ...`
    ...
  },
  ...
  "devDependencies": {
    ...
    "kysely-ctl": "^0.8.3"
    ...
  },
  ...
}

Running the following:

deno cache <some_file>

will install kysely-ctl in a node_modules folder.

Warning

It's complicated.

We use c12 for configuration file loading, which uses jiti to load .ts files. jiti doesn't support deno yet. If your config file has Deno-native URL imports, specifiers (e.g. npm:, jsr:), import map resolution, it won't work. This means you can't use kysely-ctl with SQLite on Deno, as it requires a Deno-native SQLite library - Deno doesn't support better-sqlite3 yet.

Use

Configuration

Currently, a kysely.config.ts file is required, in the project root OR .config folder. Run kysely init in your terminal to create one.

import { defineConfig } from "kysely-ctl";

export default defineConfig({
  dialect, // a Kysely dialect instance OR the name of an underlying driver library (e.g. `'pg'`).
  dialectConfig, // optional. when `dialect` is the name of an underlying driver library, `dialectConfig` is the options passed to the Kysely dialect that matches that library.
  migrations: { // optional.
    migrationFolder, // optional. name of migrations folder. default is `'migrations'`.
    migrator, // optional. a `Kysely` migrator instance. default is `Kysely`'s `Migrator`.
    provider, // optional. a `Kysely` migration provider instance. default is `kysely-ctl`'s `TSFileMigrationProvider`.
  },
  plugins, // optional. `Kysely` plugins list. default is `[]`.
});

Commands

For more information run kysely -h in your terminal.

Migrate

The migrate module mirrors Knex.js CLI's module of the same name.

knex migrate:<command>

Can now be called as either:

kysely migrate:<command>

or

kysely migrate <command>

Note

rollback without --all flag is not supported, as Kysely doesn't keep track of "migration batches".

Seed

The seed module mirrors Knex.js CLI's module of the same name.

knex seed:<command>

Can now be called as either:

kysely seed:<command>

or

kysely seed <command>

Note

We also provide kysely seed list, which is not part of Knex.js CLI.
