Angular 21+ Migration: $ARGUMENTS

If $ARGUMENTS is empty, ask the user for a component path or folder before proceeding.

Phase 1: Analyze

Read all files in the target path. For each component, directive, or service, scan for migration items below. If a folder is given, process all .ts and .html files within it.

What to migrate

Inputs / Outputs / Models:

• @Input() → input() or input.required()
• @Input() with setter → input() + linkedSignal() (preferred) or effect() (only for DOM side effects)
• @Input() + @Output() pair (e.g. value / valueChange) → model()
• @Output() → output()
• Boolean inputs: add { transform: booleanAttribute }
• Number inputs: add { transform: numberAttribute }
