[bwappsec]

Snyk has created this PR to fix 1 vulnerabilities in the npm dependencies of this project.

Snyk changed the following file(s):

• samples/client/petstore/typescript-angular-v12-provided-in-root/package.json
• samples/client/petstore/typescript-angular-v12-provided-in-root/package-lock.json

This is a major upgrade, spanning seven major versions of Angular (v13 to v19). It introduces a vast number of significant breaking changes that will require substantial code and configuration refactoring.

Key Breaking Changes:

• End of View Engine: As of v13, the legacy View Engine is removed, and Ivy is the only rendering engine. Libraries not compiled with Ivy will no longer work.
• Standalone by Default: Starting in v19, components, directives, and pipes are standalone by default, fundamentally changing the application structure away from NgModules.
• Node.js & TypeScript Requirements: The required Node.js version has increased to 18.13.0+ for Angular v17 and newer. TypeScript versions have also been updated significantly across releases.
• New Control Flow Syntax: Angular v17 introduced a new built-in control flow syntax (@if, @for) to replace structural directives like *ngIf and *ngFor.

Source: Angular Update Guide
Recommendation: A direct upgrade from v12 to v19 is not feasible. Follow the official Angular Update Guide to perform incremental upgrades one major version at a time (12 → 13, 13 → 14, etc.). This is a significant migration effort that must be planned and executed carefully.
