ng 21 rc and ngrx/signals peer dependency

[aylmercarson]

trying to install ngrx/signals against the new @angular/core": "^21.0.0-rc.0" does not succeed. the error is

error peer @angular/core@"^20.0.0" from @ngrx/signals@20.1.0

does anyone know when a compatible version of ngrx/signals will be released?

I would say, if you want to use ngrx against the release candidate of Angular 21, then just force install NgRx 20. I don't expect that you would encounter any issues.

hi - thanks, yes, i had tried that, along with legacy-peer-deps. still no joy. the install is refused.

specifically:

• Package "@ngrx/signals@20.1.0" has an incompatible peer dependency to "@angular/core@^20.0.0"
  (requires "21.0.0-rc.0" in project).

npm i @ngrx/signals --force doesn't work?

i must have taken leave of my senses. i tried both that and the legacy peer options. i have just tried it again and it seems to have gone ahead. and looking back over the command history, i can see both failures. however, now up and running again. many thanks and apologies for wasting your time :)

All good!

aha, no. i now remember why i had the issue in the first place. it will build locally but a github action refuses to build:

npm error While resolving: @ngrx/signals@20.1.0
npm error Found: @angular/core@21.0.0-rc.0
npm error node_modules/@angular/core
npm error @angular/core@"^21.0.0-rc.0" from the root project

not the end of the world but it blocks deployments...
