This video deals with the problem of authentication in REST APIs on behalf of users. It presents an overview of OAuth, which is an open standard for authentication that is common in REST APIs.

This video deals with the data sources, directory structure, and code architecture

We want to create the OAuth authentication flow in our application. This video shows how to generate a request token, send users to Twitter to sign in, and get authenticated users back to our application.

After user signed in to Twitter and authorized our application, the application now needs to get an access token to access the user’s Twitter profile and log the user in.

Now that we have access to a user’s Twitter data, we need to use the data in our application. In this video, you will learn about Twitter’s API concepts, such as cursored collections and bulk APIs.

This video deals with viewing Twitter’s ids, designing asynchronous request handlers and implementing them

In this vide, we will choose a database for our sample application. We will look at two different types of databases: relational databases and document-oriented databases. Then we’ll talk about how we would scale each type of database with our application. We will see how each of these types of databases integrates with node.js. And finally we will pick a winner.

Hitting Twitter’s API every time the app needs Twitter data is slow and can result in Twitter blocking our application. In this video, we will learn how to store Twitter’s data in our database to minimize the use of Twitter’s API.

The first step while building an API is to write the specifications. In this video, we will learn how to design the specifications from the data we have and the requirements that we want.

We know what the API should look like. Now we need to build it. In this video, we will define the API’s route handlers and call the API from the client to have a functional application.

Changing an API can break an application. For this reason, every API should have acceptance tests, which help prevent breaking apps. In this video, we will use Postman to write acceptance tests for our API.

An API that serves one request per second cannot have the same infrastructure as one that serves thousands of requests per second. In this video, we will learn how to measure the capacity of our API and how to increase that capacity by utilizing multiple CPU cores.

In this video, we will look at the other end of the application, the front end. We will start by looking at the key user moments in web applications. Then, we will look at how to test the user perceived performance using chrome dev tools and lighthouse.

A single API structure cannot fit all applications. We will look at how Facebook structured its API as a social graph. By the end of this video, you will understand what the Facebook Graph API is and how to use it.

Some data needs time to be computed on the server. This makes the server slow under heavy load. In this video, we will see the approach that GitHub uses to keep its responses fast.

The primary use of APIs is to connect applications. We will look at IFTTT, the perfect example of doing just that.

In this course, we’ve taken a pedagogical approach to explaining how APIs and authentication is done. In this video, we will look at the security issues with our API and what needs to be done to handle them.

APIs are designed to be used by other people. These users need an easy way to know the capabilities of an API without reading source code. In this video, we will take a look at the tools for generating API documentation.

Software requirements always change, and these changes should not break the apps or destroy the businesses of those using our APIs. API versioning helps us keep old clients compatible while providing new clients with all the new features.

Performance and bandwidth are limited, so we should use them as efficiently as possible. This video shows three ways of caching responses to help conserve bandwidth and maximize performance.

In this video, we will learn about the measures we can take to keep our website fast and reliable. We will start by looking at the API status pages of Twitter, Facebook, and Github.
