library1.3.0jsnpmunverified

Sequelize Make Migration (sequelizemm) is a CLI tool for generating Sequelize migration files interactively. Version 1.3.0 supports Sequelize v6 & v7, ESM and CJS, and automatically creates up/down migrations with constraints and transaction support. It uses a schema.json file to track model changes. Unlike manual migration creation, it provides an interactive prompt and synchronizes database schema with current models. Released under MIT license.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

makemigration

✓ import { makemigration } from 'sequelizemm'

✗ const makemigration = require('sequelizemm').makemigration

ESM import is preferred; CJS require works but must access the named export.

sequelizemm (CLI)

✓ npx sequelizemm

✗ sequelizemm

CLI is available globally via -g flag or via npx for local install.

Schema type

✓ import type { Schema } from 'sequelizemm'

TypeScript types are bundled; Schema type can be imported for programmatic use.

Shows how to set up the required sequelize.js file and run the CLI to generate a migration.

// Install globally or locally // npm i -g sequelizemm // or // npm install sequelizemm --save-dev // Create sequelize.js in project root: const { Sequelize } = require('sequelize'); const sequelize = new Sequelize('database', 'username', 'password', { host: 'localhost', dialect: 'postgres' // or mysql, sqlite, mssql }); // Initialize models and associations here module.exports = { sequelize }; // Run the CLI: // sequelizemm // Follow interactive prompts to create migration.

Debug

Known issues

gotchaThe sequelize.js file must export the Sequelize instance with a named export (default: 'sequelize') or use --name flag.

fix

Ensure your sequelize.js exports like: module.exports = { sequelize: sequelize } or use custom file/name via --file and --name.

affects: >=1.0.0

gotchaIf schema.json already exists from a previous run, the tool will compare against it. Deleting schema.json may cause unexpected behavior.

fix

Do not delete schema.json manually; let the tool manage it.

affects: >=1.0.0

deprecatedSequelize v5 support is deprecated; only v6 and v7 are supported in 1.3.0.

fix

Upgrade your project to Sequelize v6 or v7, or use an older version of sequelizemm.

affects: >=1.0.0 <1.3.0

gotchaThe CLI will look for sequelize.js in the current working directory unless --file is specified. If run from another directory, it may fail.

fix

Run the command from your project root or specify the full path with --file.

affects: >=1.0.0

breakingVersion 1.0.0 changed the import path from 'sequelizemm/lib/index' to just 'sequelizemm'.

fix

Update imports to use 'sequelizemm' directly.

affects: <1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'sequelize'

Sequelize is not installed as a dependency.

fix

Run 'npm install sequelize' in your project.

Error: No Sequelize instance found. Make sure you have a sequelize.js file in your project root or specify using --file

The CLI cannot find the Sequelize instance export.

fix

Create a sequelize.js file that exports a Sequelize instance, or use --file and --name flags.

TypeError: sequelize.queryInterface is not a function

The provided Sequelize instance is not initialized or is of wrong version.

fix

Ensure the sequelize instance is properly created with new Sequelize() and you are using a supported version (v6 or v7).

Error: ENOENT: no such file or directory, open './migrations/...'

The migrations directory does not exist.

fix

Create a 'migrations' folder in your project root, or configure migrations path in Sequelize.
