Are you trying with NODE_ENV=production?

sreelakshmitvvdn commented 4 years ago

no. am giving only migration:safe

masumsoft commented 4 years ago

Safe migration does not alter tables, just throws this warning if the schema does not match with db tables. This is done intentionally to make sure production data is not accidentally deleted. To enable altering the database tables automatically, you need to use migration: alter or drop.

Please also have a look at the docs related to migration for a clear understanding of the options: https://express-cassandra.readthedocs.io/en/stable/usage/#explanations-for-the-options-used-to-initialize
