Superjson is a TypeScript library that safely serializes and deserializes JavaScript values to a superset of JSON, preserving types like Date, Map, Set, and BigInt that JSON.stringify drops. It is a thin, framework-agnostic wrapper around JSON.stringify/JSON.parse with type-safe autocompletion.
Use cases
- serialize dates and bigints to json
- pass Date objects through Next.js getServerSideProps
- serialize Map and Set to JSON
- fix JSON.stringify losing types
- type-safe json serialization in typescript
- send rich objects over an api without manual conversion
When to choose
- you need Date, Map, Set, BigInt, or RegExp to survive JSON round-trips
- you hit Next.js serialization limits in getServerSideProps or getInitialProps
- you want a drop-in JSON.stringify replacement with a tiny runtime footprint
When to avoid
- your data is plain JSON-compatible types only
- you need a wire format other systems can read without the superjson meta layer
- you need binary or extremely large payload optimization
