Pounds-Conversion-RestAPI

This is a personal project, where I have explored the fundamentals of a REST API. This was done by researching API & REST API architectural style.

The project is about converting different currencies into pounds.

Technologies Used:

I have used Postgresql to store, update, delete and show the data.

I used Node.js + Express framework.

I used POSTMAN throughout the project for regular testing, using PUT, DELETE, GET & POST.

I used visual code IDE, programming in JavaScript.

How my API works:

There are 6 aspects to the API:

- Add currency
- Delete currency by ID
- Update amount by ID
- Update result
- View all currencies
- View a specific currency by ID

To add a currency you use the following route:

POST localhost:5500/api/conversion_rates/

To DELETE a currency you use the following route (1 is ID at the end of the route):

DELETE localhost:5500/api/conversion_rates/1 

To update the amount of a currency you use the following route (1 is ID at the end of the route):

PUT localhost:5500/api/conversion_rates/1

To update the result (calculate Rate * Amount) you use the following route:

GET localhost:5500/api/conversion_rates/result

To show the currency by ID use the following route (1 is ID at the end of the route):

GET localhost:5500/api/conversion_rates/1

To show all the currencies with the respective result you use the following route:

GET localhost:5500/api/conversion_rates/
