Packages

Express: A lightweight Node.js web framework for spinning up RESTful APIs. We will use this to handle routing in our backend API
body-parser: A middleware to parse incoming request inputs into our req.body object
nodemon: is a tool that helps develop node.js based applications by automatically restarting the node application when file changes in the directory are detected,
Mocha: is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun
Chai: Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework.
SuperTest: HTTP assertions made easy.

Insfrastructure Requirements

1. Node >=14.16.1

Development server

Run nodemon server.js --inspect for a dev server. Navigate to http://localhost:4444/. The app will automatically reload if you change any of the source files.

Automated API test

An Automatic REST JSON API Testing system has been implemented using Mocha & Chai. By simply running mocha should test the api endpoints.

Manually Testing the Endpoints

To test the Api, please use Postman (https://www.postman.com/) to make a call to the api POST https://exc-rates.herokuapp.com/rates passing these as the payload;

formData: {
    'from': 'eur',
    'amount': ' 13.12',
    'to': 'gbp',
    'amount2': '99',
    'action': 'add',
    'currency': 'cad'
}

The Api Endpoint GET https://exc-rates.herokuapp.com/rates returns all the Exchange rates from USD

Demo Project

The project has been deployed on firebase and a demo can be seen here https://exc-rates.herokuapp.com/rates
