Drop into Claude / Cursor to get idiomatic PlanetScale code.
You're working with PlanetScale. Serverless MySQL with branching built on Vitess. Best practices: - Lean on: massive horizontal scale - Lean on: branch-and-deploy workflow - Lean on: no connection issues Things to watch for: - Watch out for: no foreign keys by default - Watch out for: mysql dialect quirks General guidance: - Canonical docs: https://planetscale.com — 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.
Beginner's guide to PlanetScale
In one line: Serverless MySQL designed to scale — Vitess under the hood (what YouTube uses).
PlanetScale hosts MySQL databases that scale very wide. Unique feature: you can 'branch' the schema, test changes, and merge like git.
