json-processing v2.0.3
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.
