SslConfig | SignalWire

SslConfig manages SSL/TLS configuration for serving agents over HTTPS. It reads from explicit options or falls back to environment variables (SWML_SSL_ENABLED, SWML_SSL_CERT_PATH, SWML_SSL_KEY_PATH, SWML_SSL_DOMAIN). See Environment Variables for the full list.

2 
3 const ssl = new SslConfig({ certPath: './cert.pem', keyPath: './key.pem' });

Properties

enabled

boolean
