JSON-e

JSON-e is a data-structure parameterization system designed to embed context within JSON objects. It allows treating a data structure as a 'template' and transforming it using another data structure as context to produce an output data structure. Unlike string-based templating, JSON-e operates directly on data structures, ensuring valid JSON output. The project maintains a healthy release cadence, with version 4.8.2 being the latest, and aims for stability with breaking changes typically resulting from bug fixes rather than new features.
