Issue

Setup:

• Deno Version: 1.20.1
• v8 Version: 10.0.139.6
• Typescript Version: 4.6.2
• Opine Version: 2.1.4

Details

There is a type incompatibility with Deno 1.20.1 for listenAndServeTls :

error: TS2345 [ERROR]: Argument of type 'string | undefined' is not assignable to parameter of type 'string'.
  Type 'undefined' is not assignable to type 'string'.
          await server.listenAndServeTls(options.certFile, options.keyFile);
                                         ~~~~~~~~~~~~~~~~
    at ./src/application.ts

I fixed it temporarily by replacing
if (isTls) { in application.ts
with :
if (isTls && typeof options.certFile == "string" && typeof options.keyFile == "string") {

Yeah seems types just slightly mismatching now.

ListenTlsOptions have all pertinent keys as optional https://doc.deno.land/deno/stable/~/Deno.ListenTlsOptions which is inherited by opine’s HTTPSOptions https://github.com/cmorten/opine/blob/main/src/types.ts#L22 so isTls isn’t quite cutting it anymore.

Think solution would be to adjust HTTPSOptions defined in opine’s types to have the key and cert keys as non-optional.

Ok, fine, that's what I thought, thanks.

Sorry, what's the fix here? I'm getting this error with opine 2.1.4 AFAIK the latest version.

@cawoodm what is the error you are seeing? The fix for this issue was to use latest opine on latest deno (deno upgrade).
