Flatted is a fast, minimal circular JSON parser for handling JSON-compatible data that includes circular references. It provides parse and stringify functions, plus helpers like toJSON and fromJSON to preserve recursive structures across JSON serialization, with usage available as JavaScript modules or via CDN (and also language ports for PHP, Python, and Go).

Recent updates
v3.4.2
2 months agoRelease v3.4.2 makes a small internal change to how the resolver maps primitive reference values back into the input object/array. There are no published release notes (none provided), so any behavioral differences come only from the code diff and dependency/test updates.
Breakingv3.4.1
2 months agoRelease v3.4.1 has no publisher-provided release notes, so the documented change set is effectively empty. The code diff shows a project version bump plus a significant internal refactor of the Python implementation, alongside test additions and repository metadata updates.
v3.4.0
2 months agoRelease v3.4.0 was published on 2026-03-08, but no release notes were provided by the publisher. Because the notes are missing, it is not possible to reliably identify new features, breaking changes, bug fixes, security fixes, or dependency updates from the release notes alone.
