Caching

[steveoh]

I'd like to cache the dependencies that this action downloads to speed up the sequential runs. Is this a feature you would want to add to this action or would you rather users use the action/cache action to do this on their own and if so what folder should we cache and what file should we use to hash for the changes/updates check?

Hi @steveoh,

This makes total sense to cache the dependencies. I would stick with the actions/cache as this has been done exactly for this purpose.

Now, I can't answer what is required to be cached. I would look at the tool's repository directly to have more information about it. You can also have a look at this example that caches Go modules: https://github.com/actions/cache/blob/main/examples.md#go---modules

If you have a working example, I'd be interested to add it to the README.
