Proxy your specified localhost port to HTTPS, with automatic certificate installation.

• You're developing locally and stuck with SameSite: None cookie problem
• You don't want to proxy your dev to external servers
• You just wish you could use HTTPS on your localhost

Using npx from Node.JS allows you to run NPM binaries without having them installed first.

Forward port 443 (HTTPS default port) to 80 with HTTPS:

$ npx secure-localhost

Forward port 443 to 8000 (pass it to args) with HTTPS:

$ npx secure-localhost 8000

More options run npx secure-localhost --help

For the first launch, you'll asked to install the HTTPS certificate. For windows it will be a dialog prompt. For unix, a sudo password will be asked.

The certificate is saved to ~/.certs/secure-localhost-server.crt and ~/.certs/secure-localhost-server.key

• Only tested in Windows and Linux for now (Mac users: help us!)
• If ran without sudo in Unix, it uses port 8443 instead of 433
• Requires openssh to be installed/available on CLI
