Clone the repo, add jsondiff
to your path and run
jsondiff <reference.json> <comparison.json> [ignored_keys]
e.g.
jsondiff resources/a.json resources/b.json zz,c.g.h
This will use a.json as the reference file, compare b.json to it and output any differences (ignoring the keys "zz" and "c.g.h")
jsondiff expects one piece of JSON per line.
