[Snyk] Security upgrade @angular/compiler from 5.2.9 to 19.2.17

[saurabharch]

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

Snyk changed the following file(s):

• package.json
• yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

Code Review

This pull request, automatically generated by Snyk, upgrades @angular/compiler from version 5.2.9 to 19.2.17 to fix a security vulnerability. While addressing the vulnerability is important, this is a massive major version jump that introduces significant breaking changes. More critically, it only upgrades @angular/compiler while leaving all other @angular/* packages (like @angular/core and @angular/common) and related tooling (like @angular/cli and TypeScript) at versions compatible with Angular 5. Angular's packages are tightly coupled and must be on the same version. This mismatch will break the application. Therefore, this PR is not safe to merge in its current state. A full, manual migration of the entire Angular framework is necessary to properly upgrade, which will involve addressing numerous breaking changes across the codebase.

[gemini-code-assist]

This upgrade of @angular/compiler to version 19.2.17 is a significant breaking change, especially since other @angular packages like @angular/core (line 23), @angular/common (line 21), and @angular/compiler-cli (line 51, in devDependencies) remain on version 5.2.9. Angular packages are tightly coupled and must be kept on the same version to ensure compatibility. This version mismatch will almost certainly break your application's build and runtime.

A proper upgrade from Angular 5 to 19 is a major migration effort and involves more than just this one package. Key considerations include:

• Updating all @angular/* packages: All framework packages must be on the same version.
• Migrating from @angular/http: The @angular/http module (line 25) was removed in Angular 8. You'll need to migrate to @angular/common/http.
• Updating RxJS: Your project uses RxJS 5. Newer Angular versions require RxJS 6 or 7, which has many breaking changes.
• Updating TypeScript and CLI: You'll also need to update TypeScript (currently ~2.5.3) and @angular/cli (currently ~1.7.3) to versions compatible with Angular 19.

This automated PR is not safe to merge. It's recommended to perform a full, careful Angular migration, potentially using the official Angular update guide (update.angular.io) as a starting point.
