🦉 Cross-site Scripting (XSS)

[ayusuf-mq]

This is a massive upgrade across 8 major versions, from Angular 11 to 19. It includes multiple fundamental architectural changes, API removals, and a new paradigm for authoring applications. A direct migration is not feasible; a sequential, version-by-version upgrade using the official Angular Update Guide is mandatory. [2, 40]

Highlights:

• End of View Engine: The legacy View Engine is removed in v13, making the Ivy rendering engine mandatory. [16, 24] The Angular Compatibility Compiler (ngcc) is removed in v16, breaking support for any remaining View Engine-based libraries. [8, 9, 13]
• Standalone is the New Default: The architecture shifts from NgModules to Standalone Components, Pipes, and Directives, which became stable in v15 and the default in v17. [3, 4, 28]
• New Reactivity and Control Flow: Angular 17 introduces a new, built-in syntax for control flow (@if, @for) and stabilizes Signals, a new reactivity model for state management. [8, 19, 23]

Source: Angular Documentation
Recommendation: Do not merge directly. Follow the official Angular Update Guide to migrate incrementally from one major version to the next. Plan for significant code refactoring, especially around modules, component architecture, and template syntax.
