How to run

This is a Next.js responsive project bootstrapped with create-next-app and uses MongoDB Atlas for the datastore.

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

Run the Jest test:

npm run test

Run the Cypress test:

npm run test:cypress

Run the Cypress test with the LaunchPad:

npm run test:cypress:open

Troubleshoot

1. MongoDB connection timeout issue.

• It should be related to IP whitelisting. I have given access to all IPs and tested on a different machine with Mobile hotspot. If problem persists, maybe have a look local etc/hosts or other local config files.

TypeScript Challenge Instructions

Instructions

Write a Node project that:

1. reads in the file data.json transforms it into a format that matches example-output.json
2. load transformed data into a datastore - store can be of your choice, in memory or a local database
3. Create an API that has 2 get API calls. One for customers and one for orders that pull data from the datastore
4. Create a simple UI that calls the API and displays the customer and the customers orders

General Approach and Assumptions

• Solution should be implemetned in TypeScript.
• Read JSON data.json async from it's directory, convert data async, write into datastore async
• Solution should be run from the command line using npm run.
• Solution should be non-blocking.
• Solution should use React or modern equivilent for UI
• Solution APIs should be REST compliant

Criteria

Your work will be evaluated primarily on:

• Consistency of coding style.
• Correct use of promises, including proper error handling.
• Correct use of TypeScript, including interface/object definitions.
• Absence of "callback hell".
• Correct and complete unit test coverage.
• General quality of code and technical communication.
