  • keep captcha verification logic behind a simple CaptchaService interface

  • Node.js: the version supported by your NestJS v10 setup

Features​

  • ✅ Provider-based design (current provider: reCAPTCHA)
  • ✅ CaptchaGuard for route protection
  • ✅ Configurable token location (header/body) and field name
  • ✅ Uses @nestjs/axios under the hood for reCAPTCHA verification
