node-red-contrib-json

A Node-RED node for processing JSON objects using multiple query engines: JSONSelect, JSONPath, jq, and json-select. Current stable version is 0.2.0. Release cadence is irregular; this package is in early maintenance mode. Key differentiators include support for multiple query languages in one node and the ability to choose between lightweight (JSONSelect) and powerful (jq) engines. The jq engine requires the jq command-line tool to be installed separately, which is a notable dependency compared to pure JavaScript alternatives. The node integrates into Node-RED's flow-based programming environment, allowing visual wiring of JSON transformations.
