The Link Checks Action is a GitHub Action that checks if the links provided in a file are valid. It ensures that the links return a 200 response code and do not return an error. This is a safety net to ensure that URLs are not shipped broken due to mistakes that may occur during copy-pasting or refactoring.

To use this action, add it to your YML file and specify the file or files you want to check.

- name: Run URL check script
  uses: adriancoman/link-checks-action@0.1.0
  with:
    file-to-check: "{path_to_your_file}"

You can add multiple files as well, if they are comma separated:

- name: Run URL check script
  uses: adriancoman/link-checks-action@0.1.0
  with:
    file-to-check: "{path_to_1st_file},{path_to_2nd_file},{path_to_3rd_file}"

This action is particularly useful for mobile apps that hold external links in a file with constant values. For example:

object UrlConstants {
    const val TERMS = "https://www.my_awesome_website.com/terms.html"
    const val PRIVACY = "https://www.my_awesome_website.com/privacy.html"
}

By using the Link Checks Action, you can be notified if a URL is broken.

There are a lot of improvements that can be added, from the top of my head:

• Check only modified files
• Accept a list of params, instead of a single file
• Change the http response code to be valid in the intervel [200..300)

However, for now, it is a simple script that works and does its job.

The YAL file bellow is a working example of how to use the Link Checks Action in your workflow.
