Deploy Razzle on AWS

Add razzle config.

// razzle.config.js
'use strict';
module.exports = {
  options: {
    buildType: 'serverless'
  },
  modifyPaths({
    paths,
  }) {
    paths.prodAppServerIndexJs = path.join(paths.appSrc, 'index.prod');
    return paths;
  },
  modifyWebpackConfig({
    env: {
      target,
      dev,
    },
    webpackConfig,
    paths,
  }) {
    if (target === 'node') {
      if (!dev) {
        webpackConfig.entry.server = [paths.prodAppServerIndexJs];
      }
    }
    return webpackConfig;
  },
};

Modify src/server.js like so:

const public_bucket_domain = process.env.PUBLIC_BUCKET_DOMAIN || '';
const public_bucket_url = public_bucket_domain ? `https://${public_bucket_domain}` : '';
const cssLinksFromAssets = (assets, entrypoint) => {
  return assets[entrypoint] ? assets[entrypoint].css ?
  assets[entrypoint].css.map(asset=>
    `<link rel="stylesheet" href="${public_bucket_url}${asset}">`
  ).join('') : '' : '';
};
const jsScriptTagsFromAssets = (assets, entrypoint, extra = '') => {
  return assets[entrypoint] ? assets[entrypoint].js ?
  assets[entrypoint].js.map(asset=>
    `<script src="${public_bucket_url}${asset}"${extra}></script>`
  ).join('') : '' : '';
};

Add this to src/index.prod.js

const serverless = require('serverless-http');
module.exports = {
  handler: serverless(require('./server').default)
};

Add serverless-http dependency

yarn add serverless-http

Build the Razzle project

yarn build

Init cdk app

mkdir razzle-cdk
cd razzle-cdk
cdk init app --language typescript

Add razzle-cdk dependencies in razzle-cdk directory

yarn add @aws-cdk/aws-s3 @aws-cdk/aws-s3-deployment @aws-cdk/aws-lambda @aws-cdk/aws-apigateway @aws-cdk/aws-ssm @aws-cdk/aws-secretsmanager --dev

Add razzle-cdk/bin/razzle-cdk.ts

// bin/cdk.ts
#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from '@aws-cdk/core';
import { RazzleCdkStack } from '../lib/razzle-cdk-stack';
const app = new cdk.App();
new RazzleCdkStack(app, 'RazzleCdkStack', {name:'basic'});

Add razzle-cdk/lib/helpers.ts

// razzle-cdk/lib/helpers.ts
import * as SSM from '@aws-cdk/aws-ssm';
import * as CDK from '@aws-cdk/core';
export const getParam = (scope: CDK.Construct, name: string) => {
