Allow passing SSL Cert/Key when using HTTPS

What problem does this feature solve?

Allows users to utilize custom SSL certs for HTTPS.

In some cases, it might be necessary to use an SSL certificate for local development.

Moreover, these options are accepted for both webpack-dev-server and the newer webpack-serve:

• https://webpack.js.org/configuration/dev-server/#devserver-https
• https://github.com/webpack-contrib/webpack-serve#cli

I think it makes sense to expose these options to users.

Other CLIs have accepted similar PRs:

• https://github.com/pallets/flask/pull/2606

What does the proposed API look like?

The addition of --key, --cert and potentially --cacert to vue-cli-service serve.

These values would be optional when --https is used, but in order to use --key and --cert, --https would be required. Or we could infer --https from the presence of a cert/key.

OK - never mind. I figured out what was wrong. Passing --https to vue-cli-service serve appears to OVERRWRITE the https element of devServer (probably with true). That’s a bit of guesswork/inference, but what is clear, is that eliminating the --https parameter to vue-cli-service serve fixed my problem, and caused vue-cli-serve to properly use the provided certs.

You should be able to specify these options in vue.config.js, in the devServer property:

So just that I understand:

• Did you try this and it didn’t work?
• or did you not know about it?
• or did it work, but you just want these to be available as CLI arguments as well?
