JP: JSON Processing Tool

JP combines both yajson-stream and RxJS to provide a powerful command line tool for filtering and transforming json streams.

Example

Take the following ndjson as an example:

{ "num": 1 }
{ "num": 1 }
{ "num": 1 }

Then select all num and sum:

$ npm install -g json-processing
$ cat test.json | jp -l 'select(".num").reduce((a, b) => a + b, 0)' -m json
3

The -l parameter defines the filtering and transformation sequence. It must start with a call to select(path: string), which takes a yajson-stream path as parameter. The return is an Observable from RxJS.
