A JavaScript serialization library that handles values JSON.stringify cannot, such as cyclical references, Map, Set, BigInt, Dates, RegExps, and Typed Arrays. It provides stringify/parse, uneval (code generation), and async stringification of promises.
Use cases
- serialize objects with circular references
- serialize Map and Set to string
- pass rich data from server to client in SSR
- serialize BigInt and TypedArrays
- serialize data containing promises
- replace JSON.stringify for complex JavaScript values
When to choose
- you need to serialize JavaScript values JSON can't handle
- you want compact, fast, XSS-safe serialization for hydration
- you need to embed serialized data in HTML or JS output
When to avoid
- you need human-readable or stable cross-version output
- you need to serialize functions
- you only serialize plain JSON-compatible data
