Static Websites and Custom Domains Using S3 and Route 53

You have a website that needs to display a few images, as well as your content. It doesn't need to collect user data like their names, email, and password, nor does it need to upload profile images. It's simple, which is why this lab will show you how to use Amazon Simple Storage Service (S3) to host your site.

You also have a custom domain that you want to use for this website. Once we've hosted your site on S3, we'll use Amazon Route 53 to ensure that users can find it using your chosen domain.

In order to acquire these skills, we're going to build a pet adoption site that displays some text and a few images. Then we're going to route a custom domain to this website in order to make it easier for users to discover your site.

OAuth: Understanding the Logical Order

There are a few different processes that we need to understand when it comes to OAuth: 1) What happens when the server starts, 2) What happens when an authentication request is handled, and 3) What happens when a normal route with authorization is handled. We won't be writing code in this order, but these lists will help you understand their part in the processes.

When the Server Starts

1. Load express-session and passport libraries in server.js:

Alternative Tic-Tac-Toe Pseudocode/Instructions

1. In HTML, create 9 divs that each share a class and that each have a unique id.
2. In JS, create a variable called "marker" with the initial value of 'X'.
3. Cache each div in a separate variable.
4. Using those variables, add click event listeners to each.
5. Above the event listeners, create a function called renderMarker that takes in a cell that will be passed from the event listener.
6. Inside each event listener, call renderMarker and pass the current cell to it.
7. Inside renderMarker, if the marker is 'X', set the cell content to 'O' and reassign marker to 'O'. Do the opposite if the marker is 'O'.
