date-fns only
Shared
prisma only
Use date-fns for formatting, parsing, arithmetic (add/subtract days, months, years), comparison, and locale-aware output in any JavaScript environment. Import only what you need and the bundle impact is minimal.
TypeScript backends with relational DBs (PostgreSQL, MySQL, SQLite, SQL Server). Projects where type safety and DX matter. Next.js full-stack apps.
date-fns v2 has limited first-party timezone support — for complex timezone-aware applications use Luxon or the Temporal polyfill. The function-heavy API can feel verbose for simple one-liners; Day.js's method chaining is more readable in those cases.
If you need very complex SQL that Prisma can't express — you can fall back to $queryRaw. Pure NoSQL (use Mongoose for MongoDB). Extreme performance-critical paths (Prisma adds overhead vs raw SQL).
