AWS CDK Multi Tenant API Example

This project is an example implementation of multi-tenant API build with AWS CDK and Typescript created for blog post Building multi-tenant internal services in AWS and CDK: Part 1 — API Gateway and App Sync.

Deployment

Prerequisites:

1. Typescript
2. AWS CLI
3. AWS CDK CLI

If not configured add your AWS Account to environment variable CDK_DEFAULT_ACCOUNT and region to CDK_DEFAULT_REGION.

Build and deploy app with:

npm run build && npm run deploy

Test API and Update API clients

Run script that signs requests with your local AWS credentials and sends test API request.

npx ts-node scripts/invoke-api.ts

Right now the app deploys API Gateway with two clients that also use your AWS accounts. You can update list of API clients and use different AWS accounts in multi-tenant-api-example-stack.ts.

Useful commands

The cdk.json file tells the CDK Toolkit how to execute your app.

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• npm run deploy to deploy this stack to your default AWS account/region with hotswap option
• cdk deploy deploy this stack to your default AWS account/region
