FAQPage Schema

How do I enable trusted HTTPS for local development without browser warnings?▼

Automating local SSL certificate generation and trust with mkcert eliminates browser warnings during development, applying OpenSSL fallbacks to serve localhost securely across operating systems.

Can I use mkcert to configure HTTPS with Docker Compose and Nginx?▼

Yes, you can integrate generated local SSL certificates with Docker Compose and Nginx configurations to securely serve containerized frontend-backend stacks over HTTPS on your local environment.

What is the best way to set up local SSL certificates across macOS, Linux, and Windows?▼

Running an automated trust script generates local SSL certificates and integrates them into the trust stores of macOS, Linux, and Windows, ensuring cross-platform HTTPS validation.

Do I need OpenSSL if mkcert is unavailable for local HTTPS testing?▼

You do not strictly need mkcert, as OpenSSL provides a fallback option to generate local SSL certificates for HTTPS testing when mkcert is not installed in your environment.

How do I serve a Vite or Node Express app over HTTPS locally?▼

You can serve a Vite or Node Express app over HTTPS locally by running the setup script to generate trusted certificates and configuring your dev server environment to use them.
