Telstra Neurodiversity Program 2021

Introduction

This is my submission for a coding exercise that I have completed as part of the 'Telstra Neurodiversity Program'. The basic objective is to create a REST API using Spring Boot (Java) or Node JS, with a MongoDB database.

I have decided to brand this as a demo project for Node JS APIs and release it publicly for my coding portfolio.

Specifications

Create a simple REST API service in Spring Boot (or Node JS), store the data in JSON format in MongoDB and perform some simple data validations:

Store the JSON request in MongoDB (refer to below incoming request sample using "id":"{{$randomInt}}") into an “incoming” collection.
Validate the data types of the incoming JSON request. (string, boolean, integer)
Build the following methods to manage the data and store the results in a MongoDB “outgoing” collection:
- Select the largest number from the array “numbersMeetNumbers”
- Find any duplicates in the string “findDuplicates”
- Remove whitespaces from “whiteSpacesGalore” without using replace()
Store the results of the above methods in a MongoDB “outgoing” collection for a GET request
Write a unit test for one of the above methods (positive and negative)

{
    "id":"652",
    "findDuplicates": "HereWeHaveSomeDuplicatedCharacters",
    "whiteSpacesGalore": "Can we replace all this white spaces without using replace please",
    "validateMeOnlyIActuallyShouldBeABoolean": false,
    "numbersMeetNumbers": [35,2,100,15,75,25,99]
}

Technologies Used

Node JS (Backend)
Express (REST API library)
MongoDB (Database)
Mocha/Chai (Unit testing)

Installing

To run the API:

Navigate to the 'api-service' folder.
Run npm install
Then, run node server
- View this file for endpoints.

To run the unit tests:

Navigate to the 'unit-tests' folder.
Run npm install
Then, run npm test
- This command executes '/test/index.js'
