Next.js is a minimalistic framework for server-rendered React applications.

Build a Real-time Next.js 14 Chat App with Fauna 

FaunaDB is a global serverless database that gives you ubiquitous, low latency access to app data, without sacrificing data correctness. It eliminates layers of app code for manually handling data anomalies, security, and scale, creating a friendlier dev experience for you and better app experience for your users.

Now that we have user information available to us, we want to connect messages created to the users that are sending them. When we add `read` privileges to the `User` model, we can call `User.identity()` to get the user data we need to set for messages. 

Update Fauna Messages Collection with Authors

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.

For user signin, we'll implement a proper server action by creating a `actions.js` file where our server actions can live. In our login page, we'll set the component to be a client component to hold some state. This way we can use the new `useFormState` hook from `react-dom` and pass in our login server action.

Within the action we'll call our `UserLogin` function from Fauna and set a cookie with the secret we get back that we can use throughout our application.

Implement Fauna Signin with Next.js Server Actions and useFormState React Hook

Now it's time to actually sign users up for our appliaction.

We'll implement the `doSignup` function that we created earlier. This function will run on the server with the `'use server'` directive so we can instantiate a fauna client and call `UserRegistration` within this function.

From there we'll redirect the user to the `/signin` page which will error out because it's not implemented yet.

Implement Signup Functionality through Fauna with Next.js 14 Server Actions

To have actual users in our application we need to represent those users in our database. Fauna has quite a few ways you can do user authentication but we'll be creating our own using a few built-in Fauna helpers.

We'll start by setting up the necessary Fauna logic for users. We'll add a `User` collection as well as a `functions.fsl` file that we'll expose user sign up and log in. Here we'll see how Fauna gives us a built in `Credentials` document to handle email and password for a user. It also has a login function that it exposes to make that easy for us which will generate a token for a user on login.

After setting up our functions, we'll add an `UnAuthRole` as well as an `AuthRole` and give proper actions for each role.

Add Fauna User Authentication to a Next.js App

To stream messages, we'll implement logic very similar to how we stream the creation of rooms from earlier.

First, we need to convert `MessageList` into a client component. We'll get an interesting error saying that only plain objects can be passed to client components from server components. This happens because the response we get back from Fauna is pretty complex. To fix this error we'll create a simple messages array and pass that down to the `MessageList` component.

In the `MessageList` component we'll create a `useEffect` that will initiate a Fauna stream within a ref and push new messages into state that we are holding in the component.

Stream Chat Messages in Real-time in Next.js from Fauna

Now it's time to actually create messages and display them in rooms within our application.

We'll start by creating a `MessageForm` component that will send a `Message.create` query to Fauna on form submission.

Next, we'll display these messages by updating our room query to also get all the messages for that room. You'll see that we can still just perform one query because we pass in the room id and call `Message.where(.room == room)` to the query.

One note here is if you console log your messages in your page component, you'll notice that the logs show up in the terminal and not the browser. This is because we are using a server component.

Create and Display Messages using Fauna within a Room in Next.js

We'll take a moment to explore how Fauna handles one-to-many relationships inside the fauna shell. 

First we'll create a `Message` collection.

Then we'll connect to the cloud database by running `fauna shell`, because I'm logged and configured this connects to the database I'm working with.

In the terminal we'll see how to create multiple messages that are associated with a room and query for those messages by room.

Explore Faunas one-to-many Relationships between Collections in the Terminal

With rooms being created and displayed on the index page, it's now time to create dynamic routes for each room so that when you click on a room name, you are actually navigated to that room.

We'll do this by using Next.js dynamic route syntax `/rooms/[...id]/page.js`. This will render a page on any `/rooms/:id` passing the component we define the `:id` as params.

Here we'll take that id and fetch the room data from fauna with a `Room.byId` query.

Create Dynamic Routes in Next.js for Chat Rooms

We can add rooms but our application does not update and display rooms when a room is added. This should happen in real-time.

To fix this we'll add a useEffect that will query for all our rooms and use fauna's `client.stream` API to ensure that this happens in real-time.

List Available Chat Rooms in Real-time in Next.js from Fauna

The first step to building a chat app is to have rooms to chat in. We'll need to create a Room collection (or table) in Fauna that we'll be adding to.

In our Next Application we'll create a simple form that has a submit handler that will create those rooms in Fauna. We need to hold some state in our component so we'll turn the page into a client component with `'use client'`.

There will be a little bit more Fauna set up to get things working. We need to create a key for our application to interact with our database so we'll create a key by running `Key.create` in our `fauna shell`. Then we'll install the `fauna` client and make a `client.query` to create the room.

Create a Fauna Room Collection in Next.js with the fauna Client

The first step is to install and configure our database that will be backing our Next.js application. We'll be using Fauna so we head over to the Fauna website and create a database.

Back in our terminal we will install `fauna-shell` so we can interact and manage our database from within our project. After some initializing steps from the CLI we'll be set up to build the app out.

Initialize and Configure a Fauna Database inside a Next.js project with fauna-shell

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

There are several components from the `@tresjs/cientos` that you can use to enhance your **TresJS 3D scenes**.

- `ContactShadows` for performant fake shadows
- Wrap models with `Levioso` for subtle floating animations
- Add real HTML markup to your animations with `HTML`

Using these abstractions from `@tresjs/cientos`, you can create polished **3D experiences**.

Enhance Your TresJS Scenes with the @tresjs/cientos Package

In this **TresJS** lesson you will see how to connect a 3D model to your application state. You'll learn to:

- Access your model's material colors using the `materials` property from `useGLTF`
- Use Vue's `watch` function to update the model's colors when the user changes the selection in the UI

This allows you to create an interactive 3D experience that responds to user input.

Connect a TresJS Model with Vue State

In this lesson, you'll learn how to create a reactive color selector in Vue using the `useState` composable function. We'll cover:

- Creating a shared state that contains base colors and a selected base color
- Using the `toRefs` utility to convert reactive properties to refs
- Importing and using the `useState` composable in components
- Iterating through colors to create buttons
- Assigning click event handlers to update the selected color reactively

Create a Reactive Color Selector in Vue with useState

In this **TresJS** tutorial, we'll explore how to find and use free 3D models in GLTF format from sites like:

- [poly.pizza](https://poly.pizza/)
- [Sketchfab](https://sketchfab.com/)
- [pmndrs Market](https://market.pmnd.rs/)

We'll then cover using the `useGLTF` composable from `drei-sfc` to load models asynchronously, handling it gracefully with Vue's `<Suspense>` component. 

Once loaded, you will see how to explore the object and get the model node you're looking for. Then, you'll pass that node to the Vue `primitive` component's `:object` prop to render the model. 

By the end of the lesson, you'll be ready to start adding awesome 3D models to your own TresJS projects!

Load Models with useGLTF and the TresJS primitive Component

This is an overview of the [TresJS project template](https://github.com/alvarosabu/egghead-tres-3D-product-configurator/tree/main/lessons/starter).

The template is styled with the atomic CSS framework, [UnoCSS](https://unocss.dev), and comes with a default TresJS scene setup, including:

- a perspective camera
- ambient light
- directional light

There is also a color selector initially implemented using an array of colors and a `ref` variable for the selected color. Each color is rendered as a circle. 

Project Overview of the TresJS Product Template

In this **TresJS** lesson you will learn how to use `OrbitControls` from the [@tresjs/cientos](https://cientos.tresjs.org/) package to add interactivity to your scenes by:

- Importing `OrbitControls`
- Adding it below your `TresPerspectiveCamera` component

The `@tresjs/cientos` package is part of the TresJS ecosystem and provides useful abstractions and composables to extend the core framework. 


Use OrbitControls to Interact with your TresJS Scene

In this **TresJS** lesson, we explore how to animate 3D objects in a scene using the render loop. 

We'll cover:

- Using the `useRenderLoop` composable and `onLoop` callback to run code every frame
- Creating refs with `useRef` to reference and modify 3D object properties like position and rotation
- Handling varying device frame rates with `delta` or `elapsed` time for consistent animation speed

By the end of the video, you'll be ready to create smooth animations in your own TresJS scenes.

Animate TresJS Objects with the useRenderLoop Composable

In this **TresJS** lesson, you'll learn how to **enable shadows** in your 3D scenes. 

We'll cover: 
- the `shadows` prop to turn on shadows
- the `cast-shadow` property for lights
- and the `cast-shadow` and `receive-shadow` properties for meshes. 

You will see how to adjust light intensity, position, and object placement to **control the appearance of shadows**. By the end, you'll understand the key aspects of configuring shadows in TresJS scenes.

Enable Shadows in Your TresJS Scene

This TresJS lesson teaches you the basics of lighting 3D scenes. 

You'll learn how to:

- add ambient lights for overall lighting `<TresAmbientLight />`
- add directional lights for light from a specific direction `<TresDirectionalLight />`
- change light color and intensity using theprops. 

You will also see how materials, such as the `<TresMeshStandardMaterial>`, work with the lights in your scene.

Up and Running with Tanstack Router and React

Learn TanStack Router for React: set up apps, use file-based routing, manage routes, and boost app performance.


In this lesson, we explore how TanStack Router integrates with the [native browser history API](https://developer.mozilla.org/en-US/docs/Web/API/History) to manage navigation.

As we navigate through different routes, the URL changes are stored in the browser's history, allowing users to use the forward and backward buttons to traverse their navigation history.

This functionality also **enables permalinks**, meaning users can copy and paste URLs to access specific routes directly.

Additionally, we learn how to programmatically interact with the history object to move forward or backward through the navigation stack, enhancing the user experience by providing full control over navigation actions.

This compatibility with the native history API ensures that TanStack Router applications behave similarly to traditional websites, offering a seamless and intuitive user experience.

In this lesson, we explore how to hook into TanStack Router's lifecycle hooks to execute custom logic during route changes.

The hooks we'll look into are: `onEnter`, `onStay`, and `onLeave`, which are triggered when entering, staying within, or leaving a route, respectively.

All hooks receive a detailed match parameter, providing information about the route's path, ID, and tons of other details.

This allows for the implementation of features like animations or logging when navigating between routes.

We also learn how to use these hooks to track and manage state changes as users interact with the application, making it easier to implement complex behaviors based on route transitions.

Hook into Route Lifecycle Hooks in Tanstack Router

Hook into TanStack React Router's lifecycle hooks for custom route logic and animations.

In this lesson, we learn how to handle not found errors in TanStack Router by using the `notFoundComponent` at both nested and global levels.

To trigger the display of a `notFoundComponent`, we must throw a specific error using the `notFound` function within a loader or other lifecycle method of a route. This approach allows us to provide custom error messages for specific routes or globally across the application.

We explore how to define a notFoundComponent within a specific route's configuration and how to set a `defaultNotFoundComponent` at the router global level, which applies to all routes unless overridden locally. This flexibility ensures that users receive meaningful feedback when encountering non-existent routes.

Provide NotFoundComponent at Nested Route or Global Level in Tanstack Router

Handle notFound errors in TanStack Router with notFoundComponent at nested or global levels.



In this lesson, we learn how to access dynamic route parameters using the `useParams` hook in TanStack Router.

When used with a specific `Route` object, `useParams` provides type-safe access to route parameters, ensuring that TypeScript knows the exact types of these parameters.

This approach eliminates the possibility of undefined/optional values, making it safer for accessing parameters like `employeeId`.

However, when using `useParams` globally without specifying a route, it requires an options object with `{ strict: false }`, which reduces type safety.

In this case, the hook can access parameters from any route in the application, but it does not guarantee their existence or type. This flexibility allows components to be reused across different routes, but it requires careful handling of potential errors.

In this lesson, we learn how to reorganize file-based routes in TanStack Router to accommodate nested routing structures.

We explore how to create additional nested routes by converting files into directories, allowing for further nesting.

For example, to create a nested route like `/employees/$employeeId/edit`, we can create a **directory** (!) named `$employeeId` and place an `index.tsx` file inside it to define the route component for this nested route.

This approach provides flexibility in organizing files while maintaining the convention that file names and locations align with route paths. We also see how to adapt existing components and loaders to work with these reorganized routes, enabling features like edit forms or delete actions (or whatever) within nested routes.


Reorganize File-Based Routes in Tanstack Router

Reorganize file-based routes in TanStack Router for flexible nested routing.



In this lesson, we learn how to parametrize the loader for a nested route in TanStack Router.

We focus on a nested route like `/employees/$employeeId`, where the `$employeeId` is a **dynamic parameter**.

To fetch data for this route, we use a `loader` function that accesses the `$employeeId` parameter. This is achieved by using the params object available in the `loader` function, which contains the dynamic segments of the URL. We then use this parameter to call a function like `getEmployeeById`, which fetches specific employee details from an API.

We highlights that TanStack Router **automatically infers types** for these parameters, ensuring type safety for nested routes.

Parametrize Route Loader for Nested Route in Tanstack Router

In this lesson, we learn how to create nested routes and outlets in TanStack Router using file-based routing.

We start by creating a new `employees` directory and files to represent nested routes, such as `/employees/$employeeId`. The `$` symbol is used to denote dynamic parameters.

We then use the `<Link>` component from TanStack Router to create links to these nested routes, passing necessary parameters.

To render the nested content, we use the `<Outlet>` component (nested), which automatically renders child routes. This approach allows us to dynamically display stuff under a nested route.

All the time, the TanStack Router generator automatically updates the route tree based on file changes - our routing configuration remains consistent 🔥
