Documentation: routes / contact
Purpose:
Handles contact form with GET and POST; validates, verifies CAPTCHA, analyzes threats, sends email.
Lifecycle Role:
Routes for /contact and /contact/thankyou.
Dependencies:
Upstream:
- sendContactMail
- formLimiter
- verifyHCaptcha
- HttpError
- captureSecurityData
- analyzeThreatLevel
- logSecurityEvent
- qualifyLink
Downstream:
- index
Data Flow:
Inputs:
Form submission data, CAPTCHA token.
Outputs:
Redirect or error response.
Side Effects:
- Sends email.
- Creates security logs.
- Potentially blocks requests on high threat.
Performance and Scalability:
Bottlenecks:
- CAPTCHA service latency.
- Email server delays.
- Async threat analysis overhead.
Concurrency:
None specified.
Security and Stability:
Validation:
Extensive input Validation and CAPTCHA verification.
Vulnerabilities:
- Potential false positives blocking legitimate users.
- Dependency on external CAPTCHA and mail service availability.
Architecture Assessment:
Coupling:
High; integrates multiple utilities tightly.
Abstraction:
Mixed Validation, security, and communication logic.
Recommendations:
- Refactor security logic into middleware.
- Add retry/circuit breaker for CAPTCHA and mail.
- Monitor threat thresholds and tune.
- Cache CAPTCHA Validation if possible.
