How can I cache dependencies (like `node_modules`) in my GitHub Actions workflow to speed up Cloudflare Worker deployments?

Use the `actions/cache` action to cache your `node_modules` directory. This will significantly reduce the time it takes to install dependencies on subsequent workflow runs. Configure the cache key based on the `package-lock.json` or `yarn.lock` file to ensure the cache is invalidated when dependencies change. This speeds up deployments and reduces resource usage.
