What are some effective caching strategies for GitHub Actions?

Effective caching strategies for GitHub Actions include using the cache action to store dependencies, leveraging cache keys for versioning, and caching build outputs to speed up workflows.

Can you explain how to implement caching in a workflow?

Sure! You can implement caching by adding the actions/cache action in your workflow YAML file. Specify the paths to cache and define cache keys based on your dependencies.

What are cache keys and how do they work?

Cache keys are unique identifiers for your cache. They can include variables like the hash of your package-lock.json file, ensuring that the cache is updated when dependencies change.

Are there any limitations to caching in GitHub Actions?

Yes, there are limitations such as cache size (up to 2GB), and caches can expire if not used for 7 days. It's important to manage your caches effectively.
