ng generate app-shell and ng generate module --route produce broken imports when a component type is configured #34449

Command

generate

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

19.x (before the v20 file naming change)

Description

ng generate app-shell and ng generate module <name> --route <path> --module <parent> generate a component and then
reference it with a hard-coded file path and class name. Both assume the v20+ defaults (no type in the file or class
name). When the workspace configures a component type, the component inherits it and the hard-coded references no
longer match, so the build fails.

Workspaces get a component type in two common ways:

1. Every workspace updated to v20 with ng update: the migration that keeps the previous style guide behaviour
   (fdc6291) adds "@schematics/angular:component": { "type": "component" }.
2. ng new --file-name-style-guide=2016, which adds { "type": "component", "addTypeToClassName": false }.

Hard-coded references:

• packages/schematics/angular/app-shell/index.ts: withAppShell(AppShell) and
  insertImport(..., 'AppShell', './app-shell/app-shell').
• packages/schematics/angular/module/files/.../__name@dasherize__-routing__typeSeparator__module.ts.template (and the
  non-routing module template for --route without a routing module): import { <%= classify(name) %> } from './<%= dasherize(name) %>';

The library schematic had the same problem (#26981) and was fixed in 661609e by passing an explicit type: '' to the
component schematic.

Minimal Reproduction

app-shell (updated-workspace configuration):

ng new ws --defaults
cd ws
# what `ng update` to v20 adds to angular.json under projects.ws.schematics:
#   "@schematics/angular:component": { "type": "component" }
ng generate app-shell
ng build

Generated src/app/app-shell/app-shell.component.ts contains export class AppShellComponent {}, but
src/app/app.config.server.ts contains:

import { AppShell } from './app-shell/app-shell';
...
provideServerRendering(withRoutes(serverRoutes), withAppShell(AppShell))

module --route (2016 file name style):

ng new ws --no-standalone --file-name-style-guide=2016 --defaults
cd ws
ng generate module feature --route feature --module app
ng build

Generated src/app/feature/feature-routing.module.ts:

import { Feature } from './feature'; // the file is feature.component.ts

Your Environment

Angular CLI       : 22.2.3
Node.js           : 24.15.0
Package Manager   : npm 11.12.1
Operating System  : darwin arm64
@schematics/angular : 22.2.3

Anything else relevant?

• Affected since 20.0.0 (hard-coded names from 23fc8e1, "generate components without a .component
  extension/type"). Same code on 21.2.x and 22.2.x.
• Suggested fix: follow 661609e and pass type: '' (and addTypeToClassName: false, so the class name stays
  AppShell/Feature) to the component schematic in app-shell and module, so the generated files always match
  the references. Happy to send a PR.
• The module --route case with addTypeToClassName: false also hits #<issue for 01> (wrong NgModule declaration);
  link the two once filed.
