@flit/sveltekit-adapter-cdk v1.2.1

This SvelteKit adapter exports your SvelteKit project as a fully self contained AWS CDK construct, this allows you to import your SvelteKit server just like you would any other CDK construct package.

Usage

Installation

The package is available on NPM and can be installed using your package manager of choice:

npm i @flit/sveltekit-adapter-cdk

pnpm add @flit/sveltekit-adapter-cdk

yarn add @flit/sveltekit-adapter-cdk

Setup

To get started you have to configure your SvelteKit project to use this adapter:

svelte.config.js

import adapter from "@flit/sveltekit-adapter-cdk";
import { vitePreprocess } from "@sveltejs/vite-plugin-svelte";

export default {
  preprocess: vitePreprocess(),
  kit: {
    adapter: adapter({}),
  },
};

Once you have built your SvelteKit project using the new adapter you can now import it from you AWS CDK project as a CDK construct:

import { Construct } from "constructs";
import { Stack } from "aws-cdk-lib";
import { RuntimeFamily } from "aws-cdk-lib/aws-lambda";
import {
  ARecord,
  PublicHostedZone,
  RecordTarget,
} from "aws-cdk-lib/aws-route53";
import { CloudFrontTarget } from "aws-cdk-lib/aws-route53-targets";
import { LambdaPowertoolsLayer } from "cdk-aws-lambda-powertools-layer";

import { SvelteKit } from "your-sveltekit-project";

export class ExampleStack extends Stack {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    const hostedZone = PublicHostedZone.fromPublicHostedZoneAttributes(
      this,
      "HostedZone",
      {
        zoneName: "...",
        hostedZoneId: "...",
      },
    );

    const powertools = new LambdaPowertoolsLayer(this, "Powertools", {
      runtimeFamily: RuntimeFamily.NODEJS,
      includeExtras: false,
    });

    const svelteKit = new SvelteKit(this, "SvelteKit", {
      layers: [powertools],
      bundling: {
        minify: true,
        sourcesContent: false,
        externalModules: ["@aws-sdk", "@aws-lambda-powertools"],
      },
      environment: {
        POWERTOOLS_SERVICE_NAME: "example-service",
      },
    });

    new ARecord(this, "ARecord", {
      recordName: "example.com",
      zone: hostedZone,
      target: RecordTarget.fromAlias(
        new CloudFrontTarget(svelteKit.cloudFront),
      ),
    });
  }
}

This adapter currently only supports one architecture configuration, uses a cloud front instance to server pre-rendered pages from a S3 bucket and and dynamic content from a NodeJS lambda function which you can configure trough the construct parameters.

If you would like to see any other infrastructure configurations please open a issue and feel free to contribute!
