ng generate component/directive --module declares a class that doesn't exist when addTypeToClassName is false #34447

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

The addTypeToClassName option was added in 21.0.0, and the declaration code was not updated, so it never worked.

Description

When a component or directive is generated into an NgModule with addTypeToClassName: false and a type set, the
generated class and the symbol added to the NgModule don't match:

• The component/directive class is named without the type (e.g. Widget), as configured.
• The NgModule declarations (and exports with --export) import the name with the type
  (e.g. WidgetComponent), so the build fails.

This is the configuration that ng new --no-standalone --file-name-style-guide=2016 writes to angular.json:

"@schematics/angular:component": { "type": "component", "addTypeToClassName": false },
"@schematics/angular:directive": { "type": "directive", "addTypeToClassName": false }

The component and directive schematics compute the class name with addTypeToClassName
(packages/schematics/angular/component/index.ts, packages/schematics/angular/directive/index.ts), but the shared
addDeclarationToNgModule helper always appends the type:

// packages/schematics/angular/utility/add-declaration-to-ng-module.ts
const classifiedName =
  strings.classify(options.name) + (options.type ? strings.classify(options.type) : '');

Minimal Reproduction

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

Generated src/app/widget/widget.component.ts:

export class Widget {}

Updated src/app/app.module.ts:

import { WidgetComponent } from './widget/widget.component';

@NgModule({
  declarations: [App, WidgetComponent],

The same happens for ng generate directive ... --module.

Exception or Error

✘ [ERROR] TS2305: Module '"./widget/widget.component"' has no exported member 'WidgetComponent'. [plugin angular-compiler]
✘ [ERROR] NG1010: Value at position 1 in the NgModule.declarations of AppModule is not a reference

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?

• Introduced together with addTypeToClassName in e417c89 (feat(@schematics/angular): support different file name style guides in ng new #31053, v21.0.0). The same code is on 21.2.x and 22.2.x.
• Suggested fix: let addDeclarationToNgModule use the class name computed by the calling schematic (or honour
  addTypeToClassName), so the declaration matches the generated class. Happy to send a PR with specs for the
  component and directive schematics.
