How to run and test

I used Deno. brew install deno should be enough. All deps are fetched by Deno on runtime.

Start the script with

deno run --allow-read main.ts /some/path/input.json

I included a demo input.json in this repo. Invalid JSON entries, missing file inputs and wrong paths are handled gracefully by the script

run the tests with

deno test tests/tests.test.js
