JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.

This playlist will be a smorgasbord of Auth0 authentication and authorization topics. Everything from adding Auth0 to various apps, customizing your Auth0 settings, adding specific rules / audiences / features, and debugging errors. 

Within five minutes, this lesson will show you how you can go from a blank template to a completely integrated Gatsby + Auth0 website. We'll use a Gatsby recipe to install our auth0-spa-js npm package, create new pages, and add all the Auth0 boilerplate needed to initialize the Auth0 client within the website. 

We'll then review all of the code added by the gatsby recipe and finish up by configuring the app with our Auth0 account.

Authenticating Gatsby Sites with Auth0

Within this 7 minute video we will add authentication to the default next.js template with Auth0. This includes installing the nextjs-auth0 npm package, configuring your Auth0 account, creating API endpoints, adding login / logout buttons, and pulling user data from an authenticated user session (by using the native getServerSideProps function)! 

Authenticating a Next.js site with Auth0

Authentication and authorization doesn't need to be hard. In this lesson, we're going to use the Auth0 React SDK to add authentication to protect a route. Which means that a user has to be logged in in order to access any content on that page. We'll finish the lesson by sending an access token to an Express API in order to retrieve some data. 

Protecting Routes and Calling Secure APIs in React with Auth0

With Auth0's React SDK, integreting an identity provider has never been easier. With a couple changes to your React app, creating an account within Auth0, we can have a login experience ready to go! This lesson will walk through all the steps nesscary such as adding the SDK through npm, setting up your Auth0 account, adding a login/logout button, and using the Auth0 provided hook to access values. 

Adding Login to React with Auth0

In simple terms, authorization is the process of verifying what users have access to (after authenticating). This video assumes that you already have authentication set up and are ready to add authorization. 

Authentication is the process of verifying if a user is who they say they are. After a user successfully authenticates, access JWTs are issued back to the application. 

In our case of authorization, we are using the JWT (JSON web token) in our NodeJS / ExpressJS API calls, to verify the user has the correct access to the desired resource.

Role-Based Access Control (RBAC) is the idea of grouping permissions together by a role. Users are assigned a role through the Auth0 dashboard the corresponding permissions are placed on the user's access token (JWT) after authenticating. That access token can be extracted by an Auth0 SDK (this video uses JavaScipt/ ReactJS) and sent to a custom server. 

Server Side logic (this video is based on NodeJS and ExpressJS), can then check for specific permissions and then allow or reject certain resources.

Role Based Auth in NodeJS with ExpressJS and Auth0

Universal Login is Auth0's implementation of the login flow, which is the key feature of an Authorization Server. Each time a user needs to prove their identity, your applications redirect to Universal Login and Auth0 will do what is needed to guarantee the user's identity.

This video will walk you through how to customize and brand the Universal Login experience. This includes setting a custom domain, styling the user emails, and add your company logo to the form.
