Demo

Steps to replicate

• run the project
• navigate to http://localhost:4200
• Since this demo application has no validation, Please select the currencies first by selecting the 2 dropdown (AOA and USD in the above slide)
• The conversion happens everytime you lost focus on the input field. In the above slide, I entered a value from the AOA field then when I lost focus the conversion happened.
• Same goes in reverse; If you lost focus on the Selling field or the 2nd field (USD in this example). If you want to check the buying amount.

NOTE : The conversion is not comming from the endpoint provided as I'm not allowed to invoke it due to my subscription As a workaround, In the backend I randomly generate an equivalent convertion rate regardless of the currency being requested.

prerequisite

In order to run docker-compose must have Docker installed

for Windows : https://docs.docker.com/docker-for-windows/install/

How to run

1. clone the project
2. run docker-compose up --build -d
3. navigate to the UI : http://localhost:4200/

swagger ui

url : http://localhost:8080/swagger-ui.html

Technology Stack

Backend

• java-11,spring-boot and spring-webflux

Front-end

• angular 10 and ngrx for state management

Other

• Docker and docker-compose

Limitation

• No field and API validation
• Cannot use the actual conversion endpoint
• No Junit

Last Note:

• When the page loads, It calls an api from the backend which then pulls all the symbols(currency code) from api.exchange
• Everytime the user lost focus from the input field and invocation of an API happened.
• If possible, Please test accordingly as I'm not able to add validation due to time constraint.
