PSON

With static dictionaries, PSON reduces JSON payloads by up to 55%, as shown in the package.json example where it cut size from 813 to 613 bytes.

Automatically builds dictionaries per connection to minimize redundancy, ideal for session-based apps with repeated data patterns.

Uses varints and 32-bit floats where possible, borrowing from Protobuf to shrink integer and float sizes without data loss.

Works in Node.js, browsers, and AMD/CommonJS environments, making integration straightforward for full-stack JavaScript apps.
