Drop into Claude / Cursor to get idiomatic Sequelize code.
You're working with Sequelize. Mature JS ORM — predates TypeScript-era tools. Best practices: - Lean on: very mature - Lean on: broad db support Things to watch for: - Watch out for: ts story weaker - Watch out for: older api patterns General guidance: - Canonical docs: https://sequelize.org — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
