Usage

Initialization

import { setupMigration } from 'sequelize-migration-wrapper'; // TypeScript
const { setupMigration } = require('sequelize-migration-wrapper'); // CommonJS

const sequelize = new Sequelize({...});

setupMigration({
  sequelize,
  path: 'path/to/migration/scripts',
  filePattern: /\.js$/
});

Options

• sequelize (no default, must be a Sequelize instance; required),
• path (no default; required),
• filePattern (default: /\.js$/)

API

migrate()

Runs through all migration scripts in the configured folder. Umzug automatically saves which migration scripts have already been run, so it will not re-run those.

await migrateDb.migrate();

getStatus()

Get the current status of the migration

const status = await migrateDb.getStatus();

migrateNext()

Iteratively run through migration scripts.

for (const i in numberOfScriptsOrSomething) {
  await migrateDb.migrateNext();
}

reset()

Undo the last migration using Umzug's down function. This will only work if your migration scripts provide a down function. See Umzug's documentation for more details.

await migrateDb.reset();

resetPrev()

Iteratively undo a migration. This will only work if your migration scripts provide a down function. See Umzug's documentation for more details.

for (const i in numberOfScriptsOrSomething) {
  await migrateDb.resetPrev();
}
