Flatted is a tiny (0.5K) and fast JavaScript library for serializing and parsing JSON data that contains circular references, with ports for PHP, Python, and Go. It provides a drop-in parse/stringify API compatible with JSON, plus toJSON/fromJSON helpers for implicit round-tripping.

Use cases

• serialize objects with circular references to JSON
• parse JSON strings containing recursive structures
• persist cyclic data structures like linked lists or graphs
• round-trip recursive Maps through JSON.stringify
• share circular-structure serialization across JS, Python, Go, and PHP

When to choose

• you need to serialize data with circular references in a JSON-compatible format
• you want a minimal, dependency-free library with a tiny footprint
• you need consistent circular JSON handling across multiple languages

When to avoid

• you need to serialize non-JSON types like Dates, Maps, or class instances natively
• you must interoperate with standard JSON.parse/JSON.stringify on the same strings
• you need a general structured-clone solution rather than JSON-only values
