Will work on it when Angular 17 is released 😊

[mraible]

You should be able to start on it with the RC candidates before the release. Angular CLI has 17.0.0-rc.3 available, and the rest of the libraries should be available in 17.0.0-rc.2.

This is a good article detailing what's new in Angular 17: https://www.angulararchitects.io/en/blog/whats-new-in-angular-17/

Should we migrate to built-in control flow, signals and other "Angular renaissance" goodies or is this planned separately?

[mraible]

@mrts We already migrated to @if and @for for control flow. We haven't done anything with signals.

I have looked at build-esbuild status and I don't think we can migrate to it right now.

• custom build api support is not stable.
• angular-builders doesn't provide a custom builder helper yet.
• we need custom builder of i18n support.

I will remove it from tasks.

@mraible how to
use --no-standalone for angular project? need this

[mraible]

We currently don't provide support for this.

[mshima]

This is complete.

@mraible implemented new control flow migration.
@qmonmert signals migration had a different bounty #25074.
I've implemented the standalone migration and signals migration at #25120, #25068, #25047 and others.

I think this bounty can be split by @mraible and me.
