Vercel CLI v35 introduces new commands to access of deployment and runtime logs:
vercel deploy --logs deploys and shows build logs
vercel inspect --logs shows build logs for an existing deployment
vercel logs now follows runtime logs of an existing deployment
You can now use the --json option to stream logs as JSON. This makes it easier to parse and filter logs using tools like jq.
vercel logs --json | jq 'select(.level == "warning")'
Using the Vercel CLI with jq to filter for warning logs
To use these features, update to the latest version of the Vercel CLI:
Install the Vercel CLI globally using the pnpm package manager.
