This tool accepts two JSON Snyk scans and returns the difference between them. It utilizes a slightly modified version of https://github.com/hezro/snyk-code-pr-diff for the comparison.
Locally, you can clone this repository, build it via the Makefile, and run it by feeding it two JSON Snyk scan files:
make build
./bin/jsonDiff-darwin json1.json json2.json
Make sure to use the appropriate binary for your OS. The above example is assuming you are on a Mac.
make tests-coverage && open coverage.html
