Setup Project: $ARGUMENTS

If $ARGUMENTS is empty, ask: (1) project name, (2) preferred SAP Fiori theme (default: horizon).

Phase 1: Check Prerequisites

node --version   # must be ≥ 18.19
ng version       # Angular CLI must be installed

If Angular CLI is missing:

npm install -g @angular/cli

Report both versions. If Node < 18.19, stop and tell the user to upgrade Node before continuing.

Phase 2: Create Angular Project

If the user does not already have a project:

ng new [project-name] \
  --routing \
  --style=scss \
  --ssr=false \
  --package-manager=npm
cd [project-name]

If the user has an existing project, ask for its root path and cd there, then skip to Phase 3.

Phase 3: Install fundamental-ngx

Attempt ng add first:

ng add @fundamental-ngx/core

ng add installs peer dependencies and patches angular.json. However, it is known to fail with "Can not add index to parent of type array" on the budget update step, and may silently skip the styles patch even when it reports success. After it runs:

1. Check that angular.json "styles" array was updated (see Phase 4). If not, apply the patch manually.
2. Check that package.json now lists fundamental-styles and @sap-theming/theming-base-content. If not, install manually.

If ng add fails entirely (exit code 1) or the environment is offline, install manually:

npm install \
  @fundamental-ngx/core \
  @fundamental-ngx/platform \
  @fundamental-ngx/cdk \
  @fundamental-ngx/i18n \
  @angular/cdk \
  fundamental-styles \
  @sap-theming/theming-base-content

Note: @fundamental-ngx/platform is not installed by ng add @fundamental-ngx/core. If you plan to use platform form components (fdp-*), install it too.

Phase 4: Configure Theme

Ask the user which theme they want, or use the argument. Map to file paths:

Theme name	CSS variable file
horizon (default)	sap_horizon/css_variables.css
horizon-dark	sap_horizon_dark/css_variables.css
quartz	sap_fiori_3/css_variables.css
quartz-dark	sap_fiori_3_dark/css_variables.css
hcb	sap_hcb/css_variables.css
hcw	sap_hcw/css_variables.css

In angular.json, set the "styles" array to:

"styles": [
  "node_modules/@sap-theming/theming-base-content/content/Base/baseLib/[theme-folder]/css_variables.css",
  "node_modules/fundamental-styles/dist/theming/[theme-folder].css",
  "node_modules/fundamental-styles/dist/fundamental-styles.css",
  "src/styles.scss"
]

Order matters — theming variables must come before component CSS, which must come before styles.scss.

CSS warnings: esbuild will emit css-syntax-error warnings about the SAP theming metadata embedded in the css_variables.css file (it stores JSON in a CSS custom property value). These are non-blocking — the styles work correctly. You can ignore them.

Also update the initial bundle budget in angular.json. @fundamental-ngx ships large bundles; the default Angular budget is too small:

{
    "type": "initial",
    "maximumWarning": "5MB",
    "maximumError": "8MB"
}

Phase 5: Configure Animations

@fundamental-ngx does not use Angular's animation system — its overlays, dialogs, and menus animate via CSS transitions from fundamental-styles. Do not add provideAnimationsAsync() or BrowserAnimationsModule unless your own application code needs Angular animations.

If you do need Angular animations for your own components, install @angular/animations separately (npm install @angular/animations) and add provideAnimationsAsync() to app.config.ts. It is not a peer dependency of fundamental-ngx and is not installed by ng add.

Phase 6: Create Verification Component

Generate a minimal smoke-test to confirm theming and components work.

Create src/app/hello/hello.component.ts:

import { ChangeDetectionStrategy, Component, signal } from '@angular/core';
import { ButtonModule } from '@fundamental-ngx/core/button';
import { MessageStripModule } from '@fundamental-ngx/core/message-strip';

@Component({
    selector: 'app-hello',
    template: `
        <h1 style="font-family: var(--sapFontFamily); font-size: 1.5rem; margin: 1rem">Hello fundamental-ngx</h1>
        <div style="padding: 1rem; display: flex; gap: 0.5rem; align-items: center">
            <button fd-button fdType="emphasized" (click)="onClick()">Click me</button>
            <button fd-button fdType="transparent" (click)="showMessage.set(false)">Reset</button>
        </div>
        @if (showMessage()) {
            <fd-message-strip type="success" style="margin: 1rem"> Setup is working correctly! </fd-message-strip>
        }
    `,
    changeDetection: ChangeDetectionStrategy.OnPush,
    imports: [ButtonModule, MessageStripModule]
})
export class HelloComponent {
    showMessage = signal(false);
    onClick(): void {
        this.showMessage.set(true);
    }
}

Note: Do NOT use <h1 fd-title [level]="1"> — [level] is not a valid input on the fd-title directive in the currently published package. Use a plain <h1> with SAP CSS variables for font styling, or omit the title entirely.

Add HelloComponent to AppComponent's imports array and place <app-hello> in its template:

// src/app/app.component.ts  (or app.ts in Angular 21)
import { HelloComponent } from './hello/hello.component';

@Component({
    selector: 'app-root',
    template: `<app-hello></app-hello>`,
    imports: [HelloComponent]
})
export class AppComponent {}

Phase 7: Verify

ng serve

Open http://localhost:4200 and confirm:

• SAP Fiori typography is applied (correct font, not default browser sans-serif)
• "Click me" renders as a styled SAP button (not a plain grey browser button)
• Clicking it shows the success message strip with SAP green styling
• No console errors about missing CSS variables or broken imports

If the buttons look unstyled:

1. Check that angular.json styles array paths exist under node_modules/
2. Confirm ng add ran without errors (check for postinstall failures)
3. Verify the theme folder name matches exactly (case-sensitive on Linux)

Critical Rules

• Import individual modules, not barrel imports — use ButtonModule from @fundamental-ngx/core/button, NOT FundamentalNgxCoreModule; barrels are deprecated and cause tree-shaking to fail
• fd-button is an ATTRIBUTE directive — <button fd-button>, never <fd-button>
• provideAnimationsAsync() is NOT needed — @fundamental-ngx animates via CSS, not Angular's animation system. Do not add it; doing so requires @angular/animations (which ng new does not install) and will cause a build error.
• CSS import order is load-order sensitive — swapping theming and component CSS positions causes incorrect variable resolution
• ng add styles patch may silently fail — always verify the angular.json styles array after running ng add
