What is Travis CI caching and how does it work?

Travis CI caching is a feature that allows you to store dependencies and build artifacts to speed up your builds. By caching these files, you can avoid downloading them every time your build runs.

How do I set up caching in my Travis CI configuration?

To set up caching, you need to add a cache section in your .travis.yml file. You can specify directories or files to cache, like this:

cache:
  directories:
    - node_modules
    - .cache/pip

Are there any limitations to caching in Travis CI?

Yes, there are some limitations. For example, the cache size is limited to 1GB, and if a cache is not used for 30 days, it may be automatically deleted.

Can I cache multiple directories?

Absolutely! You can cache multiple directories by listing them under the directories key in your cache configuration.
