Note: I tried using fromJSON here, but it doesn't work because steps.cache-node-modules.outputs.cache-hit is either true or null, not true or false as the documentation suggests.

Note: no partial matches are allowed, because npm ci will delete node_modules if it's present. It's either a full match and npm ci is skipped entirely, or it's a cache miss and we run npm ci. We do not do npm i because it can change package-lock.json and is considered unsafe for CI environments

Some more info on what For example, if you have a dependency you're installing, it may be stored in the npm cache such that it doesn't have to be downloaded over the internet. The setup-node cache is basically the difference between running: # With caching
rm -rf node_modules
npm iand # Without caching
rm -rf node_modules
npm cache clean –force
npm iYou can run those both locally and you'll see why the setup-node cache is helpful 🙂 But it still doesn't cache our actual |

Here's a workflow run I triggered about 20 minutes ago: https://github.com/Andrew-Test-Org/Public-Test-Repo/actions/runs/5213976292 And without changing the package-lock.json, I just triggered another: https://github.com/Andrew-Test-Org/Public-Test-Repo/actions/runs/5214138966/jobs/9410020020 and you can see that the cache was restores and we did not run |
