Reusable CDK constructs

Available Constructs

• ReactRouter7App
• VpcImports

Available Utilities

• requireEnvVar

ReactRouter7App

A construct that creates a React Router 7 app using:

• AWS Lambda: to serve the serverside requests
• AWS API Gateway: to connect the Lambda function to CloudFront
• AWS CloudFront: to serve the entire application
• AWS S3: to store static assets

Should be used in combination with @ballatech/react-router7-preset-aws package to create the serverside build output.

VpcImports

Utility construct for importing an existing VPC, subnets, and security groups by ID, and providing the necessary properties to attach AWS Lambda functions to the VPC.

Usage:

import { VpcImports } from '@ballatech/cdk-constructs'
import { NodejsFunction } from 'aws-cdk-lib/aws-lambda-nodejs'

const vpcImports = new VpcImports(this, 'VpcImports', {
  vpcId: 'vpc-123',
  securityGroupIds: ['sg-abc'],
  subnetIds: ['subnet-1', 'subnet-2'],
})

new NodejsFunction(this, 'Fn', {
  ...vpcImports.lambdaProps,
  // other lambda props
})

requireEnvVar

Reads an environment variable and throws an error if it is missing or empty.

import { requireEnvVar } from '@ballatech/cdk-constructs'

const DATABASE_URL = requireEnvVar('DATABASE_URL')
