Create a table and add indexes in a single migration with Sequelize

The accepted solution is problematic if the second step fails. Transactions in each step should be used to allow a roll back to ensure all of the migration steps that are inserts or updates are undone if a problem is encountered at any step. For example:

module.exports = {
 up: async (queryIntereface) => {
    const transaction = await queryInterface.sequelize.transaction();

    try {
      await queryInterface.createTable('Todos', {
        // columns...
      }, { transaction });
      await queryInterface.addIndex('Todos', ['author_id', 'title'], { transaction }));


      await transaction.commit();
    } catch (err) {
      await transaction.rollback();
      throw err;
    }
  },

  down: async (queryInterface) {

    etc...

Yes, the methods can be chained. In your case you just perform the addIndex after createTable method

return queryInterface.createTable('Todos', {
    // columns...
}).then(() => queryInterface.addIndex('Todos', ['author_id', 'title']))
.then(() => {
    // perform further operations if needed
});
