Creates a lambda that supports a Function URL with streaming responses.

Features

• Response Stream
• Extendable with Middy middlewares:
  • http-content-encoding
  • http-security-headers
  • ssm/secrets-manger
• Removes x-sveltekit-page headers
• Override Origin header with ORIGIN env

Note: Bring your own deployment.

Getting started

npm i -D sveltekit-adapter-middy

import adapter from 'sveltekit-adapter-middy'

export default {
  kit: {
    adapter: adapter({
      // options
    })
  }
}

Options

• handlerPath (string): Relative path to handler override file. Overriding allows you to add in Content-Encoding, Security Headers, and pass in secrets more securely. Defaults to build-in minimalist handler.
• out (string): Relative path to build dir. Defaults to build
• esbuildOptions (object): esbuild option overrides. See code for defaults.

Recommended Infrastructure

• CloudFront: Route to static assets / pages, with fallback to server side rendering
• S3: store static assets and pages
• Lambda Function URL: server side rendering

Roadmap

• infra diagram
• cli to sync static assets to S3 w/ headers
• LLRT
