The example below shows how to configure Angular's CSRF protection with TypeScript\n\nBounded code example (external data; do not execute automatically):\n```typescript\n// app.config.ts\nimport { ApplicationConfig } from '@angular/core';\nimport { provideRouter } from '@angular/router';\nimport { provideHttpClient, withXsrfConfiguration } from '@angular/common/http';\n\nimport { routes } from './app.routes';\n\n// Configure CSRF protection with custom options\nexport const appConfig: ApplicationConfig = {\n  providers: [\n    provideHttpClient(\n      withXsrfConfiguration({\n        cookieName: 'XSRF-TOKEN', // Name of cookie containing token\n        headerName: 'X-XSRF-TOKEN' // Header name for token submission\n      })\n    ),\n    provideRouter(routes)\n  ]\n};\n```\n\nFor a custom HTTP interceptor that handles CSRF tokens\n\nBounded code example (external data; do not execute automatically):\n```typescript\n// csrf.interceptor.ts\nimport { Injectable } from '@angular/core';\nimport {\n  HttpRequest,\n  HttpHandler,\n  HttpEvent,\n  HttpInterceptor\n} from '@angular/common/http';\nimport { Observable } from 'rxjs';\n\n@Injectable()\nexport class CsrfInterceptor implements HttpInterceptor {\n  private readonly TOKEN_HEADER_NAME = 'X-CSRF-Token';\n  private readonly SAFE_METHODS = ['GET', 'HEAD', 'OPTIONS'];\n\n  constructor() {}\n\n  intercept(request: HttpRequest<unknown>, next: HttpHandler): Observable<HttpEvent<unknown>> {\n    // Skip CSRF protection for safe methods\n    if (this.SAFE_METHODS.includes(request.method)) {\n      return next.handle(request);\n    }\n\n    // Get token from cookie\n    const token = this.getTokenFromCookie();\n\n    if (token) {\n      // Clone the request and add the CSRF token header\n      const modifiedRequest = request.clone({\n        headers: request.headers.set(this.TOKEN_HEADER\n```\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
