JSON Parsing Test Suite Data

verified May 27, 2026

json-test-suite provides a programmatic interface to the `JSONTestSuite` data, specifically designed for testing JSON parsers. This package, currently at version 1.0.0, extracts the diverse set of JSON test cases into easily consumable JavaScript objects. It includes both valid and invalid JSON strings, along with examples designed to stress-test various aspects of JSON parsing, such as large numbers, specific character encodings, and edge cases. Its release cadence appears to be stable, with 1.0.0 being the initial significant release. Key differentiators include its direct consumption of the `nst/JSONTestSuite` data, making it a reliable source for parser validation without manual data management, and its provision of TypeScript types for improved developer experience. It primarily focuses on data delivery rather than providing a parsing implementation.
