Sequelize.sync: Create indexes when table does not exist

QUESTION

Sequelize.sync: Create indexes when table does not exist

Asked 2021-Jan-11 at 12:57

According to documentation sequelize.sync() without {force: true} or {alter:true} is supposed to ignore already existing tables and create/sync only new ones. But there are at least two use cases when existing tables are not fully ignored and there are errors introduced.

My setup:

sequelize.sync() is used as a pre-migration step to create tables that don't exist in the schema
sequelize.migrate() is used to alter any existing tables.

Note: Sequelize models are treated as a single source of truth for reflecting database schema. They are always updated to reflect all the indexes/fields existing in the database.

Steps to reproduce

Step 1: Create User model with two fields name and email. Email has a unique index

The correct and non-destructive way to sync the database in production is via migrations. This way the order of the operations (new field creation, index creation etc.) is ensured.

So, generally, sync should only be used in development and testing environments.

Quoting from the official documentation:

sync({ force: true }) and sync({ alter: true }) can be destructive operations. Therefore, they are not recommended for production-level software. Instead, synchronization should be done with the advanced concept of Migrations, with the help of the Sequelize CLI.
