Look at this Sequelize plugin:

https://www.npmjs.com/package/sequelize-noupdate-attributes

It adds support for no update and read-only attributes in Sequelize models.

In your specific case, you could configure the attribute with the following flags:

{
  title: {
    type: DataTypes.STRING,
    allowNull: false,
    unique   : true,
    noUpdate : true
  }
}

That will allow the initial set of the title attribute if is null, and then prevent any further modifications once is already set.
