WALO backend coding assessment

Hi There!

Since I have no experience in javascript and have not used nodejs or nestjs this coding challenge was challenging to do in 48 hours. Regardless, I have done the coding challenge you can find out below what I have done. I utilized conda and notepad++ for this coding challenge. I have done testing using Resty and Postman on localhost:3000/products where products is my api route. To get started please type npm run start:dev to run in production more or npm run start.

For the objectives, I was not able to complete I have the basic idea to do them but due to the time constraint I could not implement the required function. I can explain in more in detail once we talk.

You can find the relevant files in nestjs-test/src/products . I hope you are doing well and have a wonderful day!

Objectives

• Create a new bank account for a customer, with an initial deposit amount. A single customer may have multiple bank accounts. (Done)
• Transfer amounts between any two accounts, including those owned by different customers. (not done)
• Retrieve balances for a given account. (Done)
• Retrieve transfer history for a given account. (not done)
• Write tests for your business logic (Done)

Function calls(To do on postman):

• To get all the products aka accounts, this returns all the accounts currently in memory (localhost:3000/products). Please refer to get_all_accounts.png
• To insert a new account, this is done during a post call which returns the product id generated randomly using the math library and adds a default if the amount is not passed(localhost:3000/products). Please refer to insert_an_account.png (and in the body choose raw then json pass), { "name":"Branden Gibson", "bank": "RBC", "amount": 9000}
• To get a specific account this is done by passing the id of the account after route products for example (localhost:3000/products/1). This returns the details of the account along with id. Please refer to get_a_single_account.png
• To delete a specific id, the id needs to be passed after route products (localhost:3000/products/1). This returns a null value and you can see its affect by calling the get for all accounts. Please refer to delete_account.png
• To update any of the account values(name,bank or amount) you can pass these values through patch along with the id number of the account(localhost:3000/products/2). This returns a null value response and you can see its effect by calling the get for all accounts. Please refer to update_for_account.png
