How to integrate
Follow these Angular-specific instructions
Create WaitlistService with dependency injection
Build a type-safe service for waitlist operations:
// src/app/services/waitlist.service.ts
import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { catchError, map } from 'rxjs/operators';
import { environment } from '../../environments/environment';
export interface WaitlistData {
email: string;
name?: string;
[key: string]: any; // For custom fields
}
export interface WaitlistResponse {
success: boolean;
message?: string;
}
@Injectable({
providedIn: 'root' // Singleton service
})
export class WaitlistService {
private readonly apiUrl = `https://waitlister.me/s/${environment.waitlistKey}`;
constructor(private http: HttpClient) {}
submitToWaitlist(data: WaitlistData): Observable<WaitlistResponse> {
const headers = new HttpHeaders({
'Content-Type': 'application/x-www-form-urlencoded'
});
const body = new URLSearchParams();
Object.keys(data).forEach(key => {
if (data[key] !== undefined && data[key] !== null) {
body.append(key, data[key].toString());
}
});
return this.http.post(this.apiUrl, body.toString(), { headers, observe: 'response' })
.pipe(
map(response => ({
success: response.ok,
message: 'Successfully joined waitlist'
})),
catchError(error => {
console.error('Waitlist submission error:', error);
return throwError(() => ({
success: false,
message: 'Failed to join waitlist. Please try again.'
}));
})
);
}
}Create reactive form component
Build a type-safe form component with validation:
// src/app/components/waitlist-form.component.ts
import { Component, OnInit, OnDestroy } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ReactiveFormsModule, FormBuilder, FormGroup, Validators } from '@angular/forms';
import { Subject, takeUntil } from 'rxjs';
import { WaitlistService } from '../services/waitlist.service';
@Component({
selector: 'app-waitlist-form',
standalone: true,
imports: [CommonModule, ReactiveFormsModule],
template: `
<div *ngIf="submitted" class="success-message">
<h3>You're on the list! 🎉</h3>
<p>We'll notify you when we launch.</p>
</div>
<form *ngIf="!submitted" [formGroup]="waitlistForm" (ngSubmit)="onSubmit()" class="waitlist-form">
<div class="form-group">
<input
formControlName="email"
type="email"
placeholder="Your email"
[class.error]="email?.invalid && email?.touched"
/>
<div *ngIf="email?.invalid && email?.touched" class="error-message">
<span *ngIf="email?.errors?.['required']">Email is required</span>
<span *ngIf="email?.errors?.['email']">Invalid email address</span>
</div>
</div>
<div class="form-group">
<input
formControlName="name"
type="text"
placeholder="Your name (optional)"
/>
</div>
<button type="submit" [disabled]="loading || waitlistForm.invalid">
{{ loading ? 'Joining...' : 'Join Waitlist' }}
</button>
<div *ngIf="error" class="error-message">
{{ error }}
</div>
</form>
`,
styles: [`
.waitlist-form {
max-width: 500px;
margin: 0 auto;
}
.form-group {

}
input {

}
`]
})
export class WaitlistFormComponent implements OnInit, OnDestroy {
waitlistForm!: FormGroup;
loading = false;
submitted = false;
error: string | null = null;
private destroy$ = new Subject<void>();
constructor(
private fb: FormBuilder,
private waitlistService: WaitlistService
) {}
ngOnInit(): void {
this.waitlistForm = this.fb.group({
email: ['', [Validators.required, Validators.email]],
name: ['']
});
}
ngOnDestroy(): void {
this.destroy$.next();
this.destroy$.complete();
}
get email() {
return this.waitlistForm.get('email');
}
onSubmit(): void {
if (this.waitlistForm.invalid) {
return;
}
this.loading = true;
this.error = null;
this.waitlistService.submitToWaitlist(this.waitlistForm.value)
.pipe(takeUntil(this.destroy$))
.subscribe({
next: (response) => {
this.submitted = true;
this.loading = false;
this.waitlistForm.reset();
},
error: (err) => {
this.error = err.message || 'Failed to join waitlist. Please try again.';
this.loading = false;
}
});
}
}Add custom async validators
Implement async validators for advanced validation scenarios:
// src/app/validators/email-validator.ts
import { AbstractControl, AsyncValidatorFn, ValidationErrors } from '@angular/forms';
import { Observable, of, delay } from 'rxjs';
import { map, catchError } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
@Injectable({ providedIn: 'root' })
export class EmailValidatorService {
constructor(private http: HttpClient) {}
checkEmailAvailability(): AsyncValidatorFn {
return (control: AbstractControl): Observable<ValidationErrors | null> => {
if (!control.value) {
return of(null);
}
// Example: Check if email is already on waitlist
// Replace with your actual API endpoint
return this.http.get<{exists: boolean}>(`/api/check-email/${control.value}`)
.pipe(
delay(500), // Debounce
map(result => result.exists ? { emailTaken: true } : null),
catchError(() => of(null))
);
};
}
}
// Use in form:
// this.waitlistForm = this.fb.group({
// email: ['',
// [Validators.required, Validators.email],
// [this.emailValidator.checkEmailAvailability()]
// ]
// });Integrate with Angular Material
Use Angular Material for enterprise-grade UI:
// First: npm install @angular/material @angular/cdk
// src/app/components/waitlist-form.component.ts
import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ReactiveFormsModule, FormBuilder, Validators } from '@angular/forms';
import { MatInputModule } from '@angular/material/input';
import { MatButtonModule } from '@angular/material/button';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatProgressSpinnerModule } from '@angular/material/progress-spinner';
import { WaitlistService } from '../services/waitlist.service';
@Component({
selector: 'app-waitlist-form',
standalone: true,
imports: [
CommonModule,
ReactiveFormsModule,
MatInputModule,
MatButtonModule,
MatFormFieldModule,
MatProgressSpinnerModule
],
template: `
<form [formGroup]="form" (ngSubmit)="onSubmit()" class="waitlist-form">
<mat-form-field appearance="outline">
<mat-label>Email</mat-label>
<input matInput formControlName="email" type="email" required>
<mat-error *ngIf="form.get('email')?.hasError('required')">
Email is required
</mat-error>
<mat-error *ngIf="form.get('email')?.hasError('email')">
Please enter a valid email
</mat-error>
</mat-form-field>
<mat-form-field appearance="outline">
<mat-label>Name</mat-label>
<input matInput formControlName="name" type="text">
</mat-form-field>
<button mat-raised-button color="primary" type="submit" [disabled]="loading">
<mat-spinner *ngIf="loading" diameter="20"></mat-spinner>
<span *ngIf="!loading">Join Waitlist</span>
</button>
</form>
`
})
export class WaitlistFormComponent {
form = this.fb.group({
email: ['', [Validators.required, Validators.email]],
name: ['']
});
loading = false;
constructor(
private fb: FormBuilder,
private waitlistService: WaitlistService
) {}
onSubmit(): void {
if (this.form.valid) {
this.loading = true;
this.waitlistService.submitToWaitlist(this.form.value).subscribe({
next: () => this.loading = false,
error: () => this.loading = false
});
}
}
}Add comprehensive testing
Write unit tests for your waitlist service and components:
// src/app/services/waitlist.service.spec.ts
import { TestBed } from '@angular/core/testing';
import { HttpClientTestingModule, HttpTestingController } from '@angular/common/http/testing';
import { WaitlistService, WaitlistData } from './waitlist.service';
describe('WaitlistService', () => {
let service: WaitlistService;
let httpMock: HttpTestingController;
beforeEach(() => {
TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
providers: [WaitlistService]
});
service = TestBed.inject(WaitlistService);
httpMock = TestBed.inject(HttpTestingController);
});
afterEach(() => {
httpMock.verify();
});
it('should submit waitlist data successfully', () => {
const mockData: WaitlistData = {
email: '[email protected]',
name: 'Test User'
};
service.submitToWaitlist(mockData).subscribe(response => {
expect(response.success).toBe(true);
});
const req = httpMock.expectOne(request =>
request.url.includes('waitlister.me')
);
expect(req.request.method).toBe('POST');
req.flush({}, { status: 200, statusText: 'OK' });
});
it('should handle errors properly', () => {
const mockData: WaitlistData = { email: '[email protected]' };
service.submitToWaitlist(mockData).subscribe({
next: () => fail('should have failed'),
error: (error) => {
expect(error.success).toBe(false);
expect(error.message).toContain('Failed');
}
});
const req = httpMock.expectOne(request =>
request.url.includes('waitlister.me')
);
req.flush('Error', { status: 500, statusText: 'Server Error' });
});
});Configure HttpClient in app config
For standalone applications, provide HttpClient:
// src/app/app.config.ts
import { ApplicationConfig } from '@angular/core';
import { provideHttpClient } from '@angular/common/http';
import { provideRouter } from '@angular/router';
import { routes } from './app.routes';
export const appConfig: ApplicationConfig = {
providers: [
provideRouter(routes),
provideHttpClient()
]
};
// Or for NgModule-based apps:
// @NgModule({
// imports: [HttpClientModule],
// // ...
// })Add to environment and deploy
Configure for different environments and deploy:
// angular.json - configure environments
{
"projects": {
"your-app": {
"architect": {
"build": {
"configurations": {
"production": {
"fileReplacements": [{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}]
}
}
}
}
}
}
}
// Build for production:
// ng build --configuration production
// Or with environment variable:
// ng build --configuration production --env=prodNeed more details?

Quick fixes for Angular-specific problems
Ensure you've provided HttpClient in your app configuration. For standalone apps, add provideHttpClient() to app.config.ts. For NgModule apps, import HttpClientModule in your app module.
Add your Angular dev server domain (localhost:4200) and production domain to Waitlister's whitelisted domains in settings. Check browser console for the specific blocked origin.
Ensure validators are properly configured in FormBuilder. Check that you're accessing form controls correctly with .get(). Use form.valid before submitting. Add [class.error] bindings for visual feedback.
Verify service has @Injectable decorator with providedIn: 'root'. For feature modules, ensure service is provided in the module or component. Check constructor injection syntax.
Use proper typing for form controls. Import FormGroup, FormControl types. Enable strictNullChecks in tsconfig.json for better type safety. Use non-null assertion (!) when accessing form values you know exist.
Always unsubscribe from observables. Use takeUntil pattern with a destroy$ Subject. Call destroy$.next() and destroy$.complete() in ngOnDestroy. Or use async pipe in templates to auto-unsubscribe.
Check environment file paths in angular.json fileReplacements. Ensure environment.ts and environment.prod.ts exist in src/environments/. Import environment correctly in your files. Build with correct configuration flag.
For standalone components, you must explicitly import them in the component that uses them. Add to imports array of the consuming component. Unlike NgModules, standalone components aren't globally available.
In TestBed.configureTestingModule, provide all dependencies. Use HttpClientTestingModule for HTTP testing. Mock services with jasmine.createSpyObj or custom mock classes. Inject dependencies in beforeEach.
Common questions
About Angular integration
Yes! Full support for standalone components with no NgModules required. Our examples use the modern standalone API with proper imports and providers. Also backward compatible with NgModule-based applications.
Absolutely! Perfect integration with Angular Material form components. Use mat-form-field, mat-input, mat-button, and all Material components. Examples provided for Material UI integration.
Yes, reactive forms are the recommended approach! Full FormBuilder, FormGroup, FormControl support with validators. Type-safe form controls with strict typing. Perfect for complex enterprise forms.
Absolutely! Full support for async validators for server-side validation, unique email checks, or external API validation. RxJS operators make async validation elegant and testable.
Use TestBed with HttpClientTestingModule for unit testing. Mock the WaitlistService with jasmine spies. Test form validation, submission, error handling, and success states. Full E2E support with Protractor or Cypress.
Yes! Full Angular DI support. Inject WaitlistService anywhere with proper scoping. Perfect for large teams - services are singleton by default with providedIn: 'root'. Easy to mock for testing.
Absolutely! Built on RxJS observables. Use operators like switchMap, catchError, tap, finalize for complex flows. Compose submission logic with RxJS operators. Perfect for reactive programming patterns.
Yes! The embed method works with SSR. For custom forms, use TransferState or HttpClient which handles SSR automatically. Forms work in both browser and server contexts.
Yes! Perfect for NX workspaces. Create a shared library with WaitlistService for use across multiple apps. Consistent implementation across your entire monorepo with proper dependency injection.
Yes! Works perfectly with Angular Router. Add waitlist forms to any route, create dedicated /launch routes, or use route guards for conditional access. All router features work out of the box.
Yes! Angular 16+ signals are supported. Convert observables to signals with toSignal(). Use computed signals for derived state. Signals work great for form state in Angular 17+.
Create a shared WaitlistService that all teams use. Enforce consistent patterns with ESLint rules. Use strict TypeScript for compile-time safety. Document in your component library. Perfect for teams of 10+ developers.
