Learn Auth0, Jwt and Ruby

An easy to implement, adaptable authentication and authorization platform which basically makes your login box awesome.



auth0

After a user successfully logs in, Auth0 sends an ID token to your React application. Auth0, uses ID Tokens to cache user profile information and give it to a client application. The caching of ID tokens can improve the performance and responsiveness of your React application.

You can use the data from the ID token to personalize the user interface of your application. The Auth0 React SDK decodes the ID token and stores its data in the user object from the `useAuth0()` React hook. 

Customize UI With ID Token Data From The useAuth0 Hook's User Object

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.

You can log out users from your React application by logging them out of their Auth0 sessions using the `logout()` method from the Auth0 React SDK.

Create a `logout-button.js` file in the src/components/buttons folder

Create a logout button component with the following code

```js
import { useAuth0 } from "@auth0/auth0-react";
import React from "react";

export const LogoutButton = () => {
  const { logout } = useAuth0();

  const handleLogout = () => {
    logout({
      logoutParams: {
        returnTo: window.location.origin,
      },
    });
  };

  return (
    <button className="button__logout" onClick={handleLogout}>
      Log Out
    </button>
  );
};
```

The `logout() method from Auth0 React SDK clears the application session and redirects to the Auth0 /v2/logout endpoint to clear the Auth0 session.

You can pass an object argument to `logout()` to customize the logout behavior of the React application. You can define a `logoutParams` property on that object to define parameters for the /v2/logout call. This process is invisible to the user. 

Pass the `logoutParams.returnTo` option to specify the URL where Auth0 should redirect your users after they log out. 

Setting `logoutParams.returnTo` to `window.location.origin` will ensure that Auth0 redirects your users to your production URL that you add to the "Allowed Logout URLs" list.




End Auth0 User Session with the logout Method from useAuth0 Hook

In this lesson, we create an AuthenticationGuard file that uses the Auth0React SDK to protect React routes by requiring login. 

You need to create the AuthenticationGuard component, pass in a component prop, and use it to protect any React route. 

```js
import { withAuthenticationRequired } from "@auth0/auth0-react";
import React from "react";
import { PageLoader } from "./page-loader";

export const AuthenticationGuard = ({ component }) => {
  const Component = withAuthenticationRequired(component);

  return <Component />;
};
```

Will also demonstrates how to use the AuthenticationGuard component to protect the profile, and admin routes in the application. 

```js
import { useAuth0 } from "@auth0/auth0-react";
import React from "react";
import { Route, Routes } from "react-router-dom";
import { PageLoader } from "./components/page-loader";
import { AuthenticationGuard } from "./components/authentication-guard";
import { AdminPage } from "./pages/admin-page";
import { CallbackPage } from "./pages/callback-page";
import { HomePage } from "./pages/home-page";
import { NotFoundPage } from "./pages/not-found-page";
import { ProfilePage } from "./pages/profile-page";
import { ProtectedPage } from "./pages/protected-page";
import { PublicPage } from "./pages/public-page";

export const App = () => {

  return (
    <Routes>
      <Route path="/" element={<HomePage />} />
      <Route
        path="/profile"
        element={<AuthenticationGuard component={ProfilePage} />}
      />
      <Route path="/public" element={<PublicPage />} />
      <Route
        path="/protected"
        element={<AuthenticationGuard component={ProtectedPage} />}
      />
      <Route
        path="/admin"
        element={<AuthenticationGuard component={AdminPage} />}
      />
      <Route path="/callback" element={<CallbackPage />} />
      <Route path="*" element={<NotFoundPage />} />
    </Routes>
  );
};

```

Use Auth0 component withAuthenticationRequired To Protect React Router 6 Routes

The `isAuthenticated` value represents the authentication state of your users it's tracked by the Auth0 React SDK. This value returns `true` when the user has been authenticated and `false` they're when not. Use `isAuthenticated` to render UI elements conditionally depending on the authentication state of your users.

```js
import { useAuth0 } from "@auth0/auth0-react";
import React from "react";
import { LoginButton } from "../../buttons/login-button";
import { LogoutButton } from "../../buttons/logout-button";
import { SignupButton } from "../../buttons/signup-button";

export const NavBarButtons = () => {
  const { isAuthenticated } = useAuth0();

  return (
    <div className="nav-bar__buttons">
      {!isAuthenticated && (
        <>
          <SignupButton />
          <LoginButton />
        </>
      )}
      {isAuthenticated && (
        <>
          <LogoutButton />
        </>
      )}
    </div>
  );
};
```
Authentication process doesn’t happen in your React application when using Auth0. Your React application will redirect your users to the Auth0 Universal Login page. Auth0 asks for credentials and redirects the user back to your application with the result of the authentication.


Use the Value of isAuthenticated to Render Components Conditionality

Create a `signup-button.js` file under the src/components/buttons folder

Add the following code:

```js
import { useAuth0 } from "@auth0/auth0-react";
import React from "react";

export const SignupButton = () => {
  const { loginWithRedirect } = useAuth0();

  const handleSignUp = async () => {
    await loginWithRedirect({
      appState: {
        returnTo: "/profile",
      },
      authorizationParams: {
        screen_hint: "signup",
      },
    });
  };

  return (
    <button className="button__sign-up" onClick={handleSignUp}>
      Sign Up
    </button>
  );
};
```
Adding `authorizationParams` to the `loginWithRedirect()` configuration object with the `screen_hint ` property and a value of `signup` will take users from your React application to the sign-up page.

Pass authorizationParams to loginWithRedirect to Direct Users to Auth0 Sign Up

Create a buttons folder the src/components folder

Create a `login-button.js` file and add the following code:

```js
import { useAuth0 } from "@auth0/auth0-react";
import React from "react";

export const LoginButton = () => {
  const { loginWithRedirect } = useAuth0();

  const handleLogin = async () => {
    await loginWithRedirect({
      appState: {
        returnTo: "/profile",
      },
    });
  };

  return (
    <button className="button__login" onClick={handleLogin}>
      Log In
    </button>
  );
};
```

`loginWithRedirect()` redirects to the Auth0 /authorize endpoint to start the authentication process. You can pass a configuration object to this method to customize the login experience.

Setting up the value of `appState.returnTo` to "/profile", you are telling the Auth0 React SDK to: When my users log in with Auth0 and return to my React application, take them to the "Profile" page.

If you don't set up this `appState.returnTo` option, your users will be redirected by default to the / path after they log in.

Apply useAuth0 hook and loginWithReditect to Add User Login to React Application

Install the Auth React SDK on the terminal 

```bash
npm install @auth0/auth0-react
```

Create an `auth0-provider-with-navigate.js` file in the src folder.

Add the following code.

```js
import { Auth0Provider } from "@auth0/auth0-react";
import React from "react";
import { useNavigate } from "react-router-dom";

export const Auth0ProviderWithNavigate = ({ children }) => {
  const navigate = useNavigate();

  const domain = process.env.REACT_APP_AUTH0_DOMAIN;
  const clientId = process.env.REACT_APP_AUTH0_CLIENT_ID;
  const redirectUri = process.env.REACT_APP_AUTH0_CALLBACK_URL;

  const onRedirectCallback = (appState) => {
    navigate(appState?.returnTo || window.location.pathname);
  };

  if (!(domain && clientId && redirectUri)) {
    return null;
  }

  return (
    <Auth0Provider
      domain={domain}
      clientId={clientId}
      authorizationParams={{
        redirect_uri: redirectUri,
      }}
      onRedirectCallback={onRedirectCallback}
    >
      {children}
    </Auth0Provider>
  );
};
```

Wrap the `Auth0ProviderWithNavigate` component around the `App` component inside of `index.js` to give it access to the `Auth0Context`.

`Auth0ProviderWithNavigate` needs the `BrowserRouter` component from React Router to be its parent, grandparent, or great-great-great-grandparent.


Install Auth0 React SDK and Create Auth0Provider with Access to Session History

You can use the post-login Action to redirect users before an authentication transaction is complete. This lets you implement custom authentication flows that require additional user interaction beyond the standard login form.

Call `api.redirect.sendUserTo()` with the URL you want to redirect to as a string

After the redirect, in your app resume authentication by redirecting the user to the `/continue` endpoint and include the `state` parameter from the URL. 

If you don't send the original state back to the `/continue` endpoint, Auth0 will lose the context of the login transaction and the user will not be able to log in.


In your application redirect to: `https://{yourAuth0Domain}/continue?state=abc123`

After the user has been redirected to the `/continue` endpoint, the Action will resume by calling the `onContinuePostLogin` function. 

For redirects to work properly, you must have a uncomment the `onContinuePostLogin` function even if the function is empty.

Check if the user has seen the announcement 

```js
  if (!event.user.app_metadata[''announcement_seen'']) {
    api.redirect.sendUserTo("http:://localhost:3000/announcement");
  }
};
```

If the user hasn't seen the announcement set the `app_metadata`

```js
exports.onContinuePostLogin = async (event, api) => {
  api.user.setAppMetadata('announcement_seen', true);
};
``` 


Redirect User After Login with Auth0 Actions

Add the `slack-notify` npm package from the Actions editor to send a Slack message when a new user registers for your application. 

Create a Post User Registration action.

Go to `api.slack.com` create a new app, active **Incoming Webhooks**, and get your Slack Webhook URL.

> Your webhook URL contains a secret. Don't share it online, including public Git repositories.

In the Action editor store the Slack Webhook URL as a secret and add the `slack-notify` npm package.

In the Actions editor enter the follow code:

```js
const initSlackNotify = require('slack-notify')

exports.onExecutePostUserRegistration = async (event) => {
  const slack = initSlackNotify(event.secrets.SLACK_WEBHOOK_URL);
  const message = `New User: ${event.user.email}`

  slack.success({
    text: message
  })
};
```
Before deploying test out the Action by click the Test icon. Once test is successful click deploy.

Then click **Add to flow** and drag the Action into the Post User Registration flow.

Add NPM Packages and Store Secrets with Auth0 Actions

After a user successfully logs in, Auth0 sends an ID token to your React application. You can use the data from the ID token to personalize the user interface of your React application. ID tokens issued by Auth0 are [JWTs](https://jwt.io) and you can add custom claims to the JWTs using Actions.

Create a Login Action to add the user metadata as a customer claim. 


```js
exports.onExecutePostLogin = async (event, api) => {
  const namespace = `https://myapp.example.com`
  const { favorite_ninja_turtle } = event.user.user_metadata

  if (event.authorization) {
    api.idToken.setCustomClaim(`${namespace}/favorite_ninja_turtle`, favorite_ninja_turtle)
  }
};
```
Auth0 allows namespaced and non-namespaced claims.To avoid name collisions, we recommend using namespaced claims. 

You can use any non-Auth0 HTTP or HTTPS URL as a namespace identifier.

Use a URL that you control as a namespace identifier; this allows you to avoid the risk that someone else is using the same namespace. The namespace URL does not have to point to an actual resource. It is only used as an identifier; it will not be called.

The JWT returned to the requesting application is built and signed at the end of the trigger running. The final, signed JWT is not accessible in an Action.

Check out the docs to learn more about [creating custom claims](https://auth0.com/docs/secure/tokens/json-web-tokens/create-custom-claims)

Add a Custom Claim To Auth0 JWT Id Token

Add a custom field to the users metadata with the [Pre User Registration trigger](https://auth0.com/docs/customize/actions/flows-and-triggers/pre-user-registration-flow).

In the Actions editor enter the following code
```js
exports.onExecutePreUserRegistration = async (event, api) => {
  api.user.setUserMetadata("favorite_ninja_turtle","raphael" )
};
```
This action uses the [API object](https://auth0.com/docs/customize/actions/flows-and-triggers/pre-user-registration-flow/api-object) to add the new metadata before the user is saved to the database

To learn more about Auth0 user metadata [read the docs here](https://auth0.com/docs/manage-users/user-accounts/metadata)



Write Action To Add Metadata To A New User Profile

With Actions you have the option to use pre-configured Actions from the [Auth0 Marketplace](https://marketplace.auth0.com/features/actions).

Add the [Country-based Access](https://marketplace.auth0.com/integrations/country-based-access) Action to your Action library to restrict users access based on their country. 

Once the Action is added to your library, choose the Login flow trigger. Use the drag and drop flow editor to add the Country-based Access Action to the Auth0 login flow.

Add Action from Auth0 Marketplace To Restrict Access By Country

Create a new application with the Auth0 CLI with the `auth0 apps create` command.

Name the application, create a description, and select the application type.

If you don't have an application set up with Auth0 you can run `auth0 quickstarts download` to download a sample application that's already configured with Auth0. 

Once the quickstart is downloaded open your code editor and open `src/auth_config.json` file and copy the domain and clientId from the settings inside the Auth0 dashboard, if they aren't population already.

Run `npm run start` to load the application on `localhost:3000` and test out the login flow.

Create New Auth0 Application and Download Quickstart

Download the Auth0 CLI on a Mac with homebrww with the command `brew tap auth0/auth0-cli && brew install auth0` 

For download instructions for Windows or Linux check out the [Auth0 CLI's README](https://github.com/auth0/auth0-cli)

When the CLI is installed use the command `auth0 login` to connect the Auth CLI to your Auth0 tenant.

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

Now that we have both the user and the token we can encode a JWT. This is made easy by the `jsonwebtoken` library that we will be using. 

To create a function that encodes a jwt, the function will need the user and token. Inside the function, definition create a `jwtPayload` object that just contains the essential data for encoding. Then, pass the payload to the `jsonwebtoken` library `sign` method and return the signed token.

Finally we store the jwt in the user's localStorage.

Encode User Data with JSON Web Token (JWT)

Now that we have our encoded JWT we need to be able to decode it!

The `jsonwebtoken` library makes this very easy. All we have to do is pass the `jwt` and our `token` to a decoder function. In that function definition we pass the arguments into the `verify` method and return the result.

Identify Users with JWT

We are going to use our JWT to make a protected request. 

All we have to do is create a button with a click event that calls our `fetchRepos` function. In the fetchRepos function make a fetch request to the `/repos` endpoint. In the fetch, pass an Authorization header with your JWT as a Bearer token. Then just await the response!

Use JWT to Make a Protected Request

When we import assets in React components outside of the `public` folder that Nitro reads for assets by default when running the development server we need to tell Nitro how to find them with the `devProxy` configuration option.

```typescript
export default defineNitroConfig({
  renderer: './renderer.ts',
  devProxy: {
    '/app/assets': 'http://localhost:5173/app/assets'
  }
})
```

This is ultimately inadequate in scenarios where you want to import assets arbitrarily and have them "just work" but works in a pinch.



Use devProxy in Nitro Config to Serve Static Imported Assets in Dev Mode via Vite

Learn how to use devProxy in Nitro Config with Vite to serve static assets in React components in dev mode.

Start with a basic Vite React TypeScript app and enhance it for production use by integrating Nitro as the server. 

This requires a custom Vite plugin for nitro as well as a custom renderer and manually creating Nitro config.

The other way to approach this would be to add Vite to a Nitro app instead. Same basic result.

Over the years, your application have grown huge. Sometimes, really HUGE.

Many developers have contributed to the codebase. One day they pushed one coding style, a different one another day. Sometimes even different patterns and solutions for similar problems.

You want to keep your codebase consistent. In the Angular ecosystem, there were well established patterns for doing things the right way ™️. But the old solutions are being challenged by signal-based approach.

Eventually, you ask yourself the key question: **Should you integrate with the NEW solutions or stick to the battle-tested ones, but already considered LEGACY**?

That's a very good question indeed. Don't rush with architectural decisions 🤓.

## 👉 First, think of what problems you want to solve by introducing the change.

Do you have 1k LoC Angular components? Maybe even 2k? Do you and your team enjoy working with these? 😏

Where does the **domain logic and state management code** belong to - do you have a clear guidance on which code should be put where? Have you spot that different devs implement similar features in totally different ways?

Do you keep on asking the same questions over and over again: **whether this certain piece of code** should be **imperative** (plain old object properties and variables) or **reactive** (streams)? It'd be nice to keep all thinga reactive, but more often than not, it introduces complexity.

## 👉 Second, think of long-term consequences.

You are going to have more than one way to **manage the state**. But is that really an issue? If your codebase is modular, separate modules should not depend on each other in any way. Inner abstractions of one should be invisible to the other, etc.

You are going to introduce a **new tool**. On one hand, you need to learn it, and so does your team. But on the other hand, it's a breathe of fresh air. And it's useful to question the way you've been doing things so far. Maybe there's a more effective way?

You are going to embrace signal-based APIs. And that means taking taking advantage of Zoneless Angular. This means using all modern Angular APIs. And you know that signals are the future. Why would you want to stick to the **less performant, less type-safe, less flexible and, objectively, less effective solutions**?

## 👉 Finally, plan your INCREMENTAL integration.

INCREMENTAL is the absolute keyword here. You don't want to tell your PM you need to stop delivering features because of a refactor.

Actually, there's no need for a "refactor". Just pick the first new feature to be implemented. Or pick the one that needs to be extended.

NGRX Signal Store allows you to create both very simple & small stores, as well as bigger ones. **Composition** is the key here.

**Start simple**.

Create a `withState` section with the signals that hold the state. That's already reactive. And relatively simple.

```ts
const initialState: CartState = {
  items: ...,
  rebate: ...,
}

export const CartStore = signalStore(
  withState(initialState)
);
```

Create a `withMethods` section to provide ways to change the state:

```ts
export const CartStore = signalStore(
  ...
  withMethods((store) => ({
    addItem(item: ShoppingItem): void {
      patchState(store, (state) => ({ items: [ ...state.items, item ] }));
    },
    ...
);
```

Create a `withComputed` section to provide all derived computations:

```ts
export const CartStore = signalStore(
  ...
  withComputed(({ items }) => ({
    totalPrice: computed(() => items().reduce(...))
    ...
);
```

**Start simple**.

Now you can (literally) **`inject` this code into your existing solution**. All you need is to inject your brand new NGRX Signal Store implementation into a component, or a service:

```ts
@Injectable()
class ExistingBigService {
  cartStore = inject(CartStore)
  //...  
}
```

and that's it! What's beatiful is that NGRX Signal Store should remain an implementation details (of a component, service, etc). It **shouldn't leak outside to the entire application unintentionally**. Small NGRX Signal Stores help us to **keep logic more modular**.

Don't hesitate - give NGRX Signal Store a try! Start with the [_**Scalable Signals Angular Architecture with NGRX Signal Store**_](https://egghead.io/courses/scalable-signals-angular-architecture-with-ngrx-signal-store-a33abd39) course now!

In React 19, managing script tags efficiently within components can lead to performance enhancements and simpler code structures.

Originally, using script tags directly in a React component involved complex setups, like using `useEffect` to dynamically add JavaScript code. For instance, a component might dynamically inject script tags to load external widgets. This approach, while functional, resulted in multiple script tags and duplicate iframe elements. This duplication not only cluttered the output but also negatively impacted performance by loading scripts multiple times.

The workaround for this would be to manually hoist any common scripts and maybe load them when they weren't needed by any components.

With React 19 we now have a more effective method. This involves directly placing the script tag within the React component's return statement. This approach ensures that React handles the script loading, avoiding the duplication of script tags.

By implementing the script tags this way, the loading initiator becomes React DOM, which efficiently manages script loading and deduplication. This setup prevents multiple requests for the same script when the component is rendered multiple times, enhancing the overall application performance.

Furthermore, directly embedding the script tag simplifies the code, making the component cleaner and more maintainable.

Efficiently Render Script Tags in React 19 Components

Learn how to efficiently render script tags in React 19 components to improve performance by avoiding duplicate script loads and simplifying your code.

Let's learn how to dynamically manage title tags in React 19 applications. Rendering `<title>` dynamically is simple enough, however, a challenge arises when multiple title tags are present in the document, which can lead to issues with screen readers and search engine optimization (SEO). The solution presented involves ensuring that only one title tag is rendered at a time by using conditional rendering.

Also we need to make sure to have a single string within the title tag using a template literal, ensuring our HTML remains valid and optimized.


Deduplicate Title tags with React 19

Learn to manage multiple title tags in React 19 dynamically. Ensure accessibility and SEO by preventing duplicate title tags with clear examples.

In React 19, we can easily add a title tag like "Starship Deets" which then appears in the head section of the HTML even when we render it inside our components. This method also applies to meta tags such as character set and viewport settings, which are also lifted to the head section automatically.

This is an awesome feature because it maintains the same composition style we are familiar with in React components. It simplifies the handling of HTML head elements without needing extra setups like `useEffect` for accessing the head section. Even in situations where our components are rendering within a body element, like within a div, we can manage our head content directly within our components. React takes care of hoisting these elements where they need to go.


Hoist Title and Meta tags in React 19

Hoisting title and meta tags directly in React 19 components allows for simpler composition, similar to other React elements. Manage meta and title tags.

Dax Raad, known for his strong opinions on Twitter, sat down for a chat about web dev, career moves, and building cool stuff. He's not afraid to throw some heat at popular tools like [Next.js](https://nextjs.org/), though he still helps people use it. Dax is particularly excited about local-first development, which he thinks isn't getting enough attention. He argues that sometimes the best web dev move is to step away from web dev entirely and explore other areas of programming.

When it comes to career growth, Dax encourages developers to think beyond the "web dev" label and see themselves as programmers capable of tackling any challenge. He advocates for trying out weird stuff and learning unusual languages, as these experiences can lead to unexpected opportunities. Taking smart risks in your career can open doors to awesome possibilities.

In the business world, Dax is a fan of making "asymmetric bets" - moves with low downside but huge potential upside. He applies this philosophy to his work on [SST](https://sst.dev/), reasoning that even if it fails, he'll walk away with valuable experience. He also emphasizes the importance of resisting quick payouts in favor of potentially bigger wins down the road.

Looking to the future of tech, Dax is betting on local-first development. He sees potential in getting in early on emerging technologies like [Solid.js](https://www.solidjs.com/). Building in public and making connections in new tech communities can pay off in unexpected ways.

Dax also challenges the notion of constant hyper-productivity in tech. He suggests balancing focused work with time for exploration and learning. Sometimes, he points out, what seems like a "dumb" choice (like learning a niche language) can turn out to be a smart career move in the long run.

**Note:** This course is being actively developed and more lessons will be added in the future.

Cursor is an AI-enhnaced code editor that allows you to call upon the robots to refactor or stub out functions for you with natural language. 

In this course, John will show you workflows that will save you time and effort by utilizing the features such as its mult-line editing and context.

In particular, by giving Cursor's AI the proper context, whether that's lines of code or multiple files, you'll get better output when trying to extend or refactor logic that's present.
