I see @IrwinJames-FS already added the eslint commands. I will use this ticket to work on GitHub Actions to automate linting PRs into dev.

I have an issue when running the lint command.

Invalid option '--ext' The --ext flag was used to specify additional file extensions ESLint should search for when a directory was passed on the command line, such as npx eslint .. This is no longer supported when using flat config. Instead, specify the file patterns you’d like ESLint to search for directly in your config. For example, if you previously were using --ext .ts,.tsx, then you will need to update your config file like this:

I will try to resolve the issue.
