Caching dependencies

A cache stores a folder between runs. The most common use is the dependency folder, keyed on a hash of the lockfile.

Add a cache

cache:
  path: node_modules
  key: lockfile-{{ hash(package-lock.json) }}

cache:
  path: node_modules
  key: lockfile-{{ hash(package-lock.json) }}

cache:
  path: node_modules
  key: lockfile-{{ hash(package-lock.json) }}

How keys work

If the key matches a saved cache, the folder is restored before your first step. If not, the step runs normally and the cache is saved at the end of a successful run.

Limits

• A cache can be up to 5 GB.

• Caches not used for 14 days are removed.

• Caches are shared by branches of the same repository, never between repositories.
