How to auto generate migrations with Sequelize CLI from Sequelize models?

If you don't want to recreate your model from scratch, you can manually generate a migration file using the following CLI command:

sequelize migration:generate --name [name_of_your_migration]

This will generate a blank skeleton migration file. While it doesn't copy your model structure over to the file, I do find it easier and cleaner than regenerating everything. Note: make sure to run the command from the containing directory of your migrations directory; otherwise the CLI will generate a new migration dir for you

You cannot create migration scripts for existing models.

If going the classic way, you'll have to recreate the models via the CLI:

sequelize model:create --name MyUser --attributes first_name:string,last_name:string,bio:text

It will generate these files:

models/myuser.js:

"use strict";module.exports = function(sequelize, DataTypes) {  var MyUser = sequelize.define("MyUser", {    first_name: DataTypes.STRING,    last_name: DataTypes.STRING,    bio: DataTypes.TEXT  }, {    classMethods: {      associate: function(models) {        // associations can be defined here      }    }  });  return MyUser;};
