How does sequelize.sync() work, specifically the force option?

Question

What does the force option on sequelize.sync() do?

sequelize.sync({     force: true }); 

Specifically, I am interested in knowing what force: false does? Will it not sync the schema with the database?

Are there any formal docs for sequelize? I could only find examples inside the docs.

Answer 1

(More or less) formal docs and API reference can be found at http://sequelize.readthedocs.org/en/latest/api/sequelize/#sync

To your question: force: true adds a DROP TABLE IF EXISTS before trying to create the table - if you force, existing tables will be overwritten.
