Is it possible to set up a custom domain on the SST Api construct?

`sst.Api` construct uses HTTP API behind the scene. Try this:
• create an ACM Certificate with DNS validation - <https://docs.aws.amazon.com/cdk/api/latest/docs/aws-certificatemanager-readme.html#dns-validation>
• create an API Gateway DomainName - <https://docs.aws.amazon.com/cdk/api/latest/docs/aws-apigatewayv2-readme.html#custom-domain>

`sst.Api` will have built-in support for custom domain later

Hmm, so I can create a new HttpApi, like this?

`_const_ httpApi = new apig.HttpApi(this, 'HttpApi', {`
      `defaultDomainMapping: ...`
    `})`

`const api = new sst.Api(this, 'Api', {`
      `httpApi: httpApi,`

Oh no, if you use the `sst.Api` construct
```const api = new sst.Api(this, ...)```

And `api.httpApi` gives you the created HttpApi

You don’t need to manually create the `apig.HttpApi` yourself

<https://docs.serverless-stack.com/constructs/Api#httpapi>

I must be missing something obvious but I'm having a hard time figuring out how to set the defaultDomainMapping on httpApi. Could you provide an example?

<@U01MJ2R0JES> My bad. I had another look at the HttpApi doc and `defaultDomainMapping` has to be passed in on create. So I was wrong. You can’t set the domain on top the HttpApi created by  `sst.Api`

You would have to create the HttpApi construct yourself.

What’s your timeline like? I can try adding custom domain support for `sst.Api` sometime this week.

Oh, that would be great. Thank you so much!

<@U01MJ2R0JES> Just release <https://github.com/serverless-stack/serverless-stack/releases/tag/v0.9.7|v0.9.7> with custom domain support for Api construct. Some examples here - <https://docs.serverless-stack.com/constructs/Api#configuring-a-custom-domain>

To upgrade:
```$ npm install --save --save-exact @serverless-stack/cli@0.9.7 @serverless-stack/resources@0.9.7```
