To view app component logs, go to https://cloud.digitalocean.com/apps and click on your app. Click on the Logs tab, then click on a component to view its logs. The logs will be updated in real-time while the component is running.
To view build and deploy logs, go to https://cloud.digitalocean.com/apps, click on your app, and click on the Deployments tab. Click on any event in the deployment history to view all logs that were generated at build and deploy time.
