Instructions to Run

1. After downloading, run go run main.go.
   note: you may need to install google/uuid by running: go get github.com/google/uuid
             you may also need to install gorilla/mux by running: go get github.com/gorilla/mux

2. This will start running the server in localhost port :8080

3. Below I've provided two different ways to test below:

   • using Postman
   • using Rest Client plugin in VSCode

1. Using Postman

This method is to use Postman to help test the API.

POST

1. Create a POST request with the path: localhost:8080/receipts/process
2. In the request body, choose JSON and add details of the receipt you would like to process.
   EXAMPLE
   
3. This should return a body containing an id (a uuid to be specific). Make sure you copy this value.

GET

1. Create a GET request with the path: localhost:8080/receipts/{id}/points
   note: replace {id} with the id value copied in step 3 above.
2. This should return a body containing the number of points corresponding to the receipt with the id you wrote in the request.
   EXAMPLE
   

2. Using Rest Client plugin in VSCode

This VSCode plugin will make it so you can test in VSCode with the file examples.rest provided.

POST

1. Above the POST request, there is a small, clickable text with the words send request. Clicking it will generate another window with the results of running the request.
2. This should return a body containing an id value. Make sure to copy this.
   EXAMPLE
   

GET

1. On line 58 of the examples.rest file, there should be a GET request that looks like GET http://localhost:8080/receipts/{id}/points.
2. Replace {id} value with the id value copied in step 2 above.
3. Above the GET request, there is a small, clickable text with the words send request. Clicking it will generate another window with the results of running the request.
4. This should return a body containing the number of points corresponding to the receipt with the id you wrote in the request.
   EXAMPLE

Additional Notes:

• I've also printed the values to the console to show the point breakdowns.

Unrelated Notes:

In case you make it this far:

• This is my first time coding in Go, but wanted to show you that I am open to learning new tools and languages!
• Of course, this is not something I could've done without any help. I followed a few tutorials on youtube to understand the concept of setting up webservers in Go (have uploaded that work to git as well in case you're curious!).
