Fixed Nx Application Name Validation Issue ✅

Successfully fixed the validation pattern that was preventing the use of "@" symbols in application names.

Todo List:

• Understand the repository setup and dependencies
• Find the schema file for @nx/node:application generator
• Locate the problematic regex pattern ^[a-zA-Z][^:]*$
• Update the pattern to allow "@" symbols while maintaining validation intent
• Test the fix with the original failing command
• Run validation and linting per repo standards
• Commit and push changes

Summary:

Root Cause: The application schema in /packages/node/src/generators/application/schema.json used a restrictive pattern ^[a-zA-Z][^:]*$ that only allowed names starting with letters.

Solution: Updated the pattern to match the library generator pattern: (?:^@[a-zA-Z0-9-*~][a-zA-Z0-9-*._~]*\\/[a-zA-Z0-9-~][a-zA-Z0-9-._~]*|^[a-zA-Z][^:]*)$

This pattern allows:

• Scoped packages like @myorg/myapp
• Traditional names like myapp
• Maintains the original validation intent (no colons)

Verification: ✅ The original failing command now works:

npx nx g @nx/node:application --directory=apps/ws-node --framework=fastify --linter=eslint --name=@myorg/ws-node --port=3001 --dry-run

Changes Made:

• Updated /packages/node/src/generators/application/schema.json:21
• All tests pass
• Code formatted with prettier
