allow https for local testing

Hello, this is a CLI-specific feature request, so I’m submitting it here rather than through the general Firebase channel.

Scenario I’m attempting to test a Stripe integration using the local emulator, but I can’t because Stripe considers the Firebase emulator insecure. (Details at bottom.)

Current workaround is to deploy on every change, but this is slow and makes viewing logs difficult.

Due-diligence Googling reveals that there are ways of serving localhost over https – which I am also attempting – but I thought it was worth noting here, because one of the reasons I turned to Firebase was the ease of onboarding, and all-in-one workflow. Other users like me (less experienced with backend or devops) may benefit from having this built in.

Feature request: serve by default over https, or at least allow it with a flag.

For reference / reproducibility see https://github.com/stripe-samples/checkout-single-subscription/tree/master/client-only/client
specifically, in index.html, change the successUrl near the bottom to localhost:5000 for use with the Firebase emulator. Then go through the Checkout process successfully, and you’ll get the SSL: not secure error on redirect back to localhost.

@ultraGentle thanks for the feedback! We’ve investigated a few ways of serving https on Localhost but it’s basically not possible to do cross-platform through an unprivileged Node.js process.

Have you looked into using something like ngrok or another local proxy to create an HTTPS tunnel to your emulator?

Using v9 connectFirestoreEmulator, it is really not possible to use HTTPS since ssl is set to false.
