Overview

This is a companion repo for a series of blog posts on implementing a case study from Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions.

An overview of the application is shown below:

To build and deploy the application:

npm i
npm run cdk-deploy

To run the application, you need to post requests to to the requests endpoint outputted from the deployment, e.g.:

POST https://fdri4bzhll.execute-api.eu-west-2.amazonaws.com/prod/requests

{
  "personalDetails": {
    "firstName": "Alex",
    "lastName": "Pritchard",
    "niNumber": "RD843356B",
    "address": {
      "lines": ["999 Letsby Avenue"],
      "postcode": "RE4 8SD"
    }
  },
  "loanDetails": {
    "amount": 10000,
    "termMonths": 12
  }
}

To receive responses, you will need to create a .env file in the root directory that specifies the webhook that you want to receive them. For example:

WEBHOOK_URL=https://webhook.site/ec9ccd16-aa8e-4c6d-80b1-2a2beae805d8

To run the unit tests, you will need to amend the .env file to specify the region you have deployed to. For example:

AWS_REGION=eu-west-2

With this in place, you can deploy the test stacks and run the tests for the individual constructs using scripts from package.json. For example, the LoanBroker construct can be tested via the following two commands:

npm run test-loan-broker-deploy
npm run test-loan-broker
