jsonschema-key-compression

Compress JSON data based on its JSON Schema by replacing long attribute names with shorter ones. Version 1.7.0 is stable, actively maintained, and ships TypeScript types. Key differentiator: it preserves valid JSON structure, making it suitable for storage in NoSQL databases or browser storage where gzip is inefficient on small payloads. Provides 40% size reduction on average. Does not require a build step or schema transformation.
