domain?
Type Input
<
string
|
Object
>
Set a custom domain for your WebSocket API.
Automatically manages domains hosted on AWS Route 53, Cloudflare, and Vercel. For other
providers, you’ll need to pass in a cert
that validates domain ownership and add the
DNS records.
By default this assumes the domain is hosted on Route 53.
For domains hosted on Cloudflare.
domain.cert?
Type Input
<
string
>
The ARN of an ACM (AWS Certificate Manager) certificate that proves ownership of the domain. By default, a certificate is created and validated automatically.
To manually set up a domain on an unsupported provider, you’ll need to:
- Validate that you own the domain by creating an ACM certificate. You can either validate it by setting a DNS record or by verifying an email sent to the domain owner.
- Once validated, set the certificate ARN as the
cert
and setdns
tofalse
. - Add the DNS records in your provider to point to the API Gateway URL.
domain.dns?
Type Input
<
false
|
sst.aws.dns
|
sst.cloudflare.dns
|
sst.vercel.dns
>
Default sst.aws.dns
The DNS provider to use for the domain. Defaults to the AWS.
Takes an adapter that can create the DNS records on the provider. This can automate validating the domain and setting up the DNS routing.
Supports Route 53, Cloudflare, and Vercel adapters. For other providers, you’ll need
to set dns
to false
and pass in a certificate validating ownership via cert
.
Specify the hosted zone ID for the Route 53 domain.
Use a domain hosted on Cloudflare, needs the Cloudflare provider.
Use a domain hosted on Vercel, needs the Vercel provider.
domain.name
Type Input
<
string
>
The custom domain you want to use.
Can also include subdomains based on the current stage.
domain.path?
Type Input
<
string
>
The base mapping for the custom domain. This adds a suffix to the URL of the API.
Given the following base path and domain name.
The full URL of the API will be https://api.example.com/v1/
.
Be default there is no base path, so if the name
is api.example.com
, the full URL will be https://api.example.com
.

Returns ApiGatewayWebSocketRoute
Add a route to the API Gateway WebSocket API.
There are three predefined routes:
- $connect: when the client connects to the API
- $disconnect: when the client or the server disconnects from the API
- $default: the default or catch-all route
In addition, you can create custom routes. When a request comes in, the API Gateway
will look the specific route defined by the user. If no route matches, the $default
route will be invoked.
Here’s how you add a simple route.
Add a default route.
Enable auth for a route.
Customize the route handler.
ApiGatewayWebSocketRouteArgs
auth?
Type Input
<
Object
>
