sequelize-typescript-migration-fix

library0.0.2jsnpmunverified

A migration tool for Sequelize with TypeScript decorators, generating migration files automatically by scanning models and detecting changes. Version 0.0.2, based on sequelize-typescript. It generates up/down migration commands like Django's makemigration. Community fork of sequelize-auto-migrations adapted for TypeScript. Not actively maintained; issues with undo order and limited documentation.

Code

Verified usage

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

SequelizeTypescriptMigration

✓ import { SequelizeTypescriptMigration } from 'sequelize-typescript-migration-fix'

✗ const { SequelizeTypescriptMigration } = require('sequelize-typescript-migration-fix')

ESM import only; package ships TypeScript types but uses CommonJS exports.

makeMigration

✓ SequelizeTypescriptMigration.makeMigration(sequelize, options)

✗ SequelizeTypescriptMigration.makeMigration(options, sequelize)

First argument must be Sequelize instance, second options object.

Sequelize

✓ import { Sequelize } from 'sequelize-typescript'

✗ import { Sequelize } from 'sequelize'

Must import Sequelize from sequelize-typescript for decorator support.

Demonstrates automatically generating a migration file from TypeScript models using SequelizeTypescriptMigration.

import { Sequelize } from 'sequelize-typescript'; import { SequelizeTypescriptMigration } from 'sequelize-typescript-migration-fix'; import path from 'path'; async function migrate() { const sequelize = new Sequelize({ database: 'test', dialect: 'sqlite', storage: ':memory:', models: [path.join(__dirname, '/models')], }); await SequelizeTypescriptMigration.makeMigration(sequelize, { outDir: path.join(__dirname, '../migrations'), migrationName: 'initial', preview: false, }); } migrate().catch(console.error);

Debug

Known issues

deprecatedUndo (down) operations may not work correctly due to relation ordering issues.

fix

Manually edit generated down migration or use alternative tools.

affects: 0.0.2

gotchaModel files must be loaded before calling makeMigration; otherwise no changes detected.

fix

Ensure sequelize models option points to correct directory or manually import models.

affects: *

breakingPackage only works with sequelize-typescript; not compatible with plain sequelize models.

fix

Use sequelize-typescript decorators (@Table, @Column) in models.

affects: 0.0.2

gotchaTable names are generated using Sequelize's default pluralization, not model names.

fix

Set @Table({ tableName: 'your_table_name' }) to override.

affects: *

deprecatedPackage appears unmaintained since 2020; no updates for newer Sequelize versions.

fix

Consider using sequelize-auto-migrations or custom scripts.

affects: 0.0.2

Errors

Common errors & fixes

TypeError: sequelize.modelManager is undefined

Using plain Sequelize (not sequelize-typescript) which lacks modelManager.

fix

Import Sequelize from 'sequelize-typescript' and use decorators.

No changes detected. Make sure your models are loaded.

Models not imported before calling makeMigration.

fix

Load models via sequelize.addModels() or include them in Sequelize constructor's models option.

Cannot find module 'sequelize-typescript'

Missing peer dependency.

fix

Install sequelize-typescript: npm install sequelize-typescript
