[Bug]: Storybook Angular 10.5 blocks Angular 22 upgrade due to TypeScript peer range excluding 6.x

[a-martsul]

Describe the bug

I am trying to upgrade an Angular workspace from Angular 21 to Angular 22 using the official Angular CLI migration flow.

Angular 22 requires TypeScript 6.0.x, but Storybook Angular 10.5 declares TypeScript peer dependency as:

^4.9.0 or ^5.0.0
This excludes all TypeScript 6 versions and causes ng update to fail on peer dependency resolution.

So even though Storybook Angular says Angular versions below 23 are supported, Angular 22 migration cannot complete because TypeScript 6 is required by Angular and rejected by Storybook peer range.

Reproduction link

https://stackblitz.com/github/storybookjs/sandboxes/tree/next/angular-cli/default-ts/after-storybook?file=package.json

Reproduction steps

Create an Angular 21 project with Storybook Angular 10.5.
Ensure Storybook packages are on 10.5.0.
Run Angular upgrade:
nvm use 22.22.3
npx ng update @angular/core@22 @angular/cli@22 @angular-eslint/schematics@22 --allow-dirty --verbose
Observe migration failure with peer dependency conflict:
Storybook Angular requires TypeScript ^4.9.0 or ^5.0.0
Angular 22 wants TypeScript 6.0.3

Additional context

• This is a blocker for all Angular projects using Storybook 10.5 that attempt
  to follow the official Angular 22 migration path via ng update.
• The issue is reproducible locally with Node 22.22.3 + npm 10.9.8.
• Angular 22 peer requirement: typescript >=6.0 <6.1
  (from @angular-devkit/build-angular@22.0.6)
• Storybook Angular peer requirement: typescript ^4.9.0 || ^5.0.0
  (from @storybook/angular@10.5.0)
• These two ranges are mutually exclusive and cannot coexist.
• Expected fix: update typescript peer range in @storybook/angular to
  ^4.9.0 || ^5.0.0 || ^6.0.0

Hi @a-martsul! I'm Dosu and I'm helping the Storybook team.

This TypeScript 6 peer dependency gap is already being addressed. A maintainer confirmed the fix is in PR #35455, which updates the TypeScript peer range to include 6.x [1].

In the meantime, you can work around the install failure by using --legacy-peer-deps (npm) or the equivalent flag in your package manager to bypass the strict peer resolution during ng update.

Once the patch ships (likely in the next 10.5.x release), you should be able to upgrade cleanly without any workaround.

To reply, just mention @dosu.

The issue is fixed and will be released in 10.5.1!

Hi, I don't think this issue is actually fixed in 10.5.1. The peer dependency range for @storybook/angular-vite has been widened, but not the range for @storybook/angular, which is the subject of this issue.

It seems to have been widened for @storybook/angular in 10.6.0-alpha.1. Is this expected to land in a 10.5 patch as well?

@valentinpalkovic This is not fixed like @pmo-edora said. Could you please also patch the next 10.5.x version of @storybook/angular to include TypeScript 6, so that we dont have to wait for the release of the next 10.6 version. Thank you very much in advance :)
