You should have basic exposure with MongoDB and understanding of simple database commands. You will make use of those skills to build a simple web app that can perform operations against your database.
In this week's files, you are given "bank_index.ejs" and "accounts_summary.ejs" for you to use. "accounts_summary.ejs" is similar to the example used within the class video. It should receive an object "accounts" which is an array of objects, each having an accountId, name, and balance. (This should match the fields from your BankDB database). Thus, this should be the page that is used to render the current balance of all known accounts. The "bank_index.ejs" file should be rendered as the "home/landing" page when you first connect to your web app via the browser. It has two parts. The first is a form with a button to display all balances. It does a POST to the /accounts_summary endpoint which should be connected to the "accounts_summary.ejs" page we just described. It then has a second form with a few fields {accountIdA, accountIdB, amount} its purpose is to allow the user to 'transfer' money from one account to another. This will POST to the /transfer endpoint.
Points for this assignment are awarded by completing the following criteria:
1) Create a bank.js application that starts a webserver and waits for requests.
2) Your webserver should display/render "bank_index.ejs" at the "/" endpoint.
3) When the user clicks 'Show Balances' it should properly POST to /accounts_summary and render "accounts_summary.ejs"
4) The /accounts_summary request should properly connect to your database such that the page from the last step accurately displays the data from the BankDB database.
5) When the user clicks 'Transfer' it should properly POST to /transfer and render some result page that tells the user the request is complete. (A static page/text is sufficient and no additional database logic is necessary for this part).
For Part 6, be sure to have gone over "Parsing Parameters" and "Callbacks".
6) Add the appropriate logic to perform the transfer of funds within the BankDB records.
6a) The funds should be correctly removed from accountIdA.
6b) The funds should be correctly added to accountIdB.
6c) Verify that both accounts do indeed exist before performing the transfer.
6d) Verify that accountIDA has sufficient funds before performing the transfer.
