Upgrading Javascript things is always a chore.
That's why these blogposts keep appearing.

So I've used the tool in [2] to check my dependency requirements but there's also [1] if you're interested.
Upgrading node.js
cd ~ rm nodejs tar zxvf ~/Downloads/node-v20.15.0-darwin-arm64.tar.gz ln -s node-v20.15.0-darwin-arm64 nodejs
Upgrading typescript
Upgrading typescript using "npm install -g typescript@latest".
Upgrading zone.js
I'm hoping Angular does this for me.
Upgrading Angular
For my "personal" project.
npm install -g @angular/cli@18 ng update @angular/core@17 @angular/cli@17 ng update @angular/core@18 @angular/cli@18 @ng-bootstrap/ng-bootstrap@17 ngx-cookie-service@18
For my "admin" project, the thing below only worked after upgrading cdk and material to 17.
ng update @angular/core@18 @angular/cli@18 @ng-bootstrap/ng-bootstrap@17 ngx-cookie-service@18 @angular/cdk@18 @angular/material@18
Upgrading dependencies
ng update bootstrap bootswatch material-icons
My dependencies for "personal" project
- @kolkov/angular-editor
- the editor I use in my webapps
- @ng-bootstrap/ng-bootstrap
- integration between angular and bootstrap
- @popperjs/core
- this is used for tooltips by ng-bootstrap
- bootstrap
- bootstrap, is awesome
- bootswatch
- free themes for bootstrap, I like/use "cyborg" as a darkmode theme.
- material-icons
- latest icon fonts and CSS for self-hosting material design icons.
- ngx-cookie-service
- Angular service to read, set and delete browser cookies.
ng update @angular/cdk@16 @angular/material@16 ng update @angular/cdk@17 @angular/material@17
My dependencies for "admin" project
- @angular/material
- for creating of a virtual scroller
- @angular/cdk
- for creation of a virtual scroller
- @ng-bootstrap/ng-bootstrap
- integration between angular and bootstrap
- @popperjs/core
- this is used for tooltips by ng-bootstrap

- ngx-cookie-service
- Angular service to read, set and delete browser cookies.
Things I noticed
- Migrate application projects to the new build system.
- You can read more about this, including known issues and limitations, here: https://angular.dev/tools/cli/build-system-migration The output location of the browser build has been updated from "../webapp" to "../webapp/browser". You might need to adjust your deployment pipeline or, as an alternative, set outputPath.browser to "" in order to maintain the previous functionality.
- Replace deprecated HTTP related modules with provider functions.
- HttpClientModule replaced with provideHttpClient, withInterceptorsFromDi
Error messages when upgrading
Package "@ng-bootstrap/ng-bootstrap" has an incompatible peer dependency to "@angular/common" (requires "^16.0.0" (extended), would install "18.0.6").
[WARNING] Polyfill for "@angular/localize/init" was added automatically. [plugin angular-polyfills] In the future, this functionality will be removed. Please add this polyfill in the "polyfills" section of your "angular.json" instead.
I found the answer to this one in [3] on StackOverflow.
[WARNING] Unable to locate stylesheet: /assets/css/bootstrap.min.css [WARNING] Unable to locate stylesheet: /assets/css/karchan.css
Replaced this with a ThemeService (which is nice) which I found at [4].
And removed the hardcoded stylesheets in index.html. These are now added by the ThemeService.
Final result

Small note
I am using the assets to store a normal bootstrap (bootstrap.min.css) and a darkmode bootstrap (bootstrap.darkmode.min.css).
These come from respectively node_modules/bootstrap/dist/css/bootstrap.min.css and node_modules/bootswatch/dist/cyborg/bootstrap.min.css.
