A tool to lint your JSON files with jq in CI/CD pipelines.

Overview

A tool to check your JSON files in CI/CD pipelines using jsonlint.

Also see: validate-json for our bash plugin to do the same thing.

This tool has been written and tested using GitHub Actions but it should work out of the box with a lot of other CI/CD tools.
