When deploying a Node.js application, if the
NODE_ENVenvironment variable hasn’t been set to production, you may see the following warning:
Skip Pruning Because NODE_ENV is Not ‘Production’
This occurs because the
NODE_ENV variable isn’t set to production by default during application creation.
To resolve or prevent this issue, manually add the
NODE_ENV environment variable when adding your application or in your application’s Environment variables. If you add the environment variable after the application has been created, you can redeploy it using Deploy changes.
