ness doctor

Diagnoses the current Ness application and exits unsuccessfully when a required check fails.

ness doctor

The command verifies:

• Node.js satisfies the minimum version
• package.json exists
• a compatible @nessframework/core is installed
• a compatible @nessframework/nest is installed
• ness.config.mjs (or a legacy Vite configuration) is present
• app/root exists
• the application route directory exists
• the Nest root module exists at app/server/app.module

Use it in bug reports and CI diagnostics. For operating-system and installed-tool versions, use ness info.
