tbonelee opened a new pull request, #5260:
URL: https://github.com/apache/zeppelin/pull/5260
### What is this PR for?
`zeppelin-web-angular` was on Angular 13 (end-of-life). This upgrades it to
Angular 21 (latest), one major version at a time so each step stays small and
reviewable. The production build, lint, and dev-server are green at every
bump.
Included:
- Angular 13 to 21 (framework, CLI, CDK), bumped lock-step one major at a
time
- ng-zorro-antd to 21, adapting to its breaking changes (moved/removed entry
points, checkbox / input-number / modal API changes, native CSS animations)
- Pinned Node 18 to 22 (npm 8 to 10) for the frontend-maven-plugin and
`engines`
- ESLint 8 (eslintrc) to ESLint 9 (flat config)
- Adopt required modern Angular APIs: built-in control flow
(`@if/@for/@switch`),
`provideHttpClient`, explicit zone change detection, `standalone: false` on
NgModule declarations, RxJS 7 typing
No intended functional or UI changes. This is a framework and tooling upgrade
only. Commits are grouped per major version (and per concern within a
version)
so the PR can be reviewed commit by commit.
