Caching Dependencies for Speed
Implement caching to significantly speed up your workflow execution by reusing generated dependencies and build outputs.
Speed Up Workflows with Caching
Ever notice your workflow re-downloading the same dependencies every time? It slows things down!
Caching in GitHub Actions lets you store and reuse files from previous runs. This dramatically speeds up subsequent workflow executions.
Meet the Cache Action
GitHub provides a special action called actions/cache@v3. This action is designed to save and restore files to make your workflows faster.
It's smart: it checks if the cache already exists before trying to restore, and saves it if it doesn't.
