ApiGatewayV2

Reference doc for the `sst.aws.ApiGatewayV2` component.

The ApiGatewayV2 component lets you add an Amazon API Gateway HTTP API to your app.

Create the API

const api = new sst.aws.ApiGatewayV2("MyApi");

Add a custom domain

new sst.aws.ApiGatewayV2("MyApi", {
  domain: "api.example.com"
});

Add routes

api.route("GET /", "src/get.handler");
api.route("POST /", "src/post.handler");

Configure the routes

You can configure the route.

api.route("GET /", "src/get.handler", {
  auth: { iam: true }
});

Configure the route handler

You can configure the route handler function.

api.route("POST /", {
  handler: "src/post.handler",
  memory: "2048 MB"
});

Default props for all routes

You can use the transform to set some default props for all your routes. For example, instead of setting the memory for each route.

api.route("GET /", { handler: "src/get.handler", memory: "2048 MB" });
api.route("POST /", { handler: "src/post.handler", memory: "2048 MB" });

You can set it through the transform.

const api = new sst.aws.ApiGatewayV2("MyApi", {
  transform: {
    route: {
      handler: (args, opts) => {
        // Set the default if it's not set by the route
        args.memory ??= "2048 MB";
      }
    }
  }
});

api.route("GET /", "src/get.handler");
api.route("POST /", "src/post.handler");

With this we set the memory if it’s not overridden by the route.

Constructor

}

cors.allowMethods?

Default [”*”]

The HTTP methods that are allowed when calling the HTTP API.

{
  cors: {
    allowMethods: ["GET", "POST", "DELETE"]
  }
}

Or the wildcard for all methods.

{
  cors: {
    allowMethods: ["*"]
  }
}

cors.allowOrigins?

Type Input<Input<string>[]>

Default [”*”]

The origins that can access the HTTP API.

{
  cors: {
    allowOrigins: ["https://www.example.com", "http://localhost:60905"]

    exposeHeaders: ["date", "keep-alive", "x-custom-header"]
  }
}

cors.maxAge?

Type Input<“${number} minute” | “${number} minutes” | “${number} hour” | “${number} hours” | “${number} second” | “${number} seconds” | “${number} day” | “${number} days”>

Default “0 seconds”

The maximum amount of time the browser can cache results of a preflight request. By default the browser doesn’t cache the results. The maximum value is 86400 seconds or 1 day.

{
  cors: {
    maxAge: "1 day"
  }
}

domain?

Type Input<string | Object>

cert?
dns?
name
path?

Set a custom domain for your HTTP 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.

{
  domain: "example.com"
}

For domains hosted on Cloudflare.

{
  domain: {
    name: "example.com",
    dns: sst.cloudflare.dns()
  }
}

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 set dns to false.
Add the DNS records in your provider to point to the API Gateway URL.

{
  domain: {
    name: "example.com",
    dns: false,
    cert: "arn:aws:acm:us-east-1:112233445566:certificate/3a958790-8878-4cdc-a396-06d95064cf63"
  }
}

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.

{
  domain: {
    name: "example.com",
    dns: sst.aws.dns({
      zone: "Z2FDTNDATAQYW2"
    })
  }
}

Use a domain hosted on Cloudflare, needs the Cloudflare provider.

{
  domain: {
    name: "example.com",
    dns: sst.cloudflare.dns()
  }
}

Use a domain hosted on Vercel, needs the Vercel provider.

{
  domain: {
    name: "example.com",
    dns: sst.vercel.dns()
  }
}

domain.name

Type Input<string>

The custom domain you want to use.

{
  domain: {
    name: "example.com"
  }
}

Can also include subdomains based on the current stage.

{
  domain: {
    name: `${$app.stage}.example.com`
  }
}

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.

{
  domain: {
    name: "api.example.com",
    path: "v1"
  }
}

The full URL of the API will be https://api.example.com/v1/.

By default there is no base path, so if the name is api.example.com, the full URL will be https://api.example.com.

transform?

Type Object

api?
domainName?
logGroup?
route? Object
- args?
- handler?

route

route(rawRoute, handler, args?)

Parameters

rawRoute string
The path for the route.
handler Input<string | FunctionArgs | “arn:aws:lambda:${string}”>
The function that’ll be invoked.
args? ApiGatewayV2RouteArgs
Configure the route.

Returns ApiGatewayV2LambdaRoute

Add a route to the API Gateway HTTP API. The route is a combination of

An HTTP method and a path, {METHOD} /{path}.
Or a $default route.

A method could be one of GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS, or ANY. Here ANY matches any HTTP method.

The path can be a combination of

Literal segments, /notes, /notes/new, etc.
Parameter segments, /notes/{noteId}, /notes/{noteId}/attachments/{attachmentId}, etc.
Greedy segments, /{proxy+}, /notes/{proxy+}, etc. The {proxy+} segment is a greedy segment that matches all child paths. It needs to be at the end of the path.

The $default is a reserved keyword for the default route. It’ll be matched if no other route matches.

When a request comes in, the API Gateway will look for the most specific match. If no route matches, the $default route will be invoked.

Add a simple route.

api.route("GET /", "src/get.handler");

Match any HTTP method.

api.route("ANY /", "src/route.handler");

Add a default route.

api.route("GET /", "src/get.handler")
api.route($default, "src/default.handler");

Add a parameterized route.

api.route("GET /notes/{id}", "src/get.handler");

Add a greedy route.

api.route("GET /notes/{proxy+}", "src/greedy.handler");

Enable auth for a route.

api.route("GET /", "src/get.handler")
api.route("POST /", "src/post.handler", {
  auth: {
    iam: true
  }
});

Customize the route handler.

api.route("GET /", {
  handler: "src/get.handler",
  memory: "2048 MB"
});

Or pass in the ARN of an existing Lambda function.
