To add a component from Shadcn, you'll need to follow these steps. Go to the Shadcn docs and click on the component you want to use.

For another approach, see: Nextjs Shadcn Template

The command to add a component to your project can be found on the component page. For example, to add the Button component, you'll run the command `npx shadcn-ui@latest add button` in your terminal.

You'll need to modify the command slightly if you use a different package manager. After running the command, you can import the component in the file where you want to use it.

To install Next.js, you need to choose the framework you're currently using. Next.js is the framework used in this article, so select that option.

You'll need to initialize a new Next.js project to get started. This will create a new project directory with two new directories: components and lib.

Next.js projects typically have these directories, which will be added to your project when you initialize it. The components directory is where you'll store reusable UI components.

To set up Next.js, you'll need to install it and configure your project. You can do this by initializing a new Next.js project, which will create the necessary directories and files.

With Next.js installed, you'll be able to create and manage your UI components in the components directory. This is where the magic happens, so make sure you understand how to use it.

If you're upgrading to Next.js 15, you'll want to know about the status of React 19 support for your dependencies.

The upgrade process can be tracked using a table created by the developer, which lists the shadcn/ui dependencies and their React 19 support status.

Here are the packages that already work with React 19: radix-ui, lucide-react, class-variance-authority, tailwindcss-animate, embla-carousel-react, recharts, react-hook-form, react-resizable-panels, sonner, input-otp, and vaul.

The react-day-picker package works with React 19, but requires a flag for npm.

The @radix-ui/react-icons package is still in progress, with a PR in place to upgrade its React 19 support.

Adding a component to your project can be a straightforward process. To start, you'll want to go to the Shadcn docs, where you can find the component you're interested in using.

Click on the component you want to use, and you'll see the command you should run to add it to your project. This command is usually specific to the component, so make sure to follow the instructions carefully.

For example, to add the Button component from Shadcn, you can follow these steps:

Remember to modify the command if you use a different package manager.

Shadcn components come with default styling that looks good and has hover effects, so you don't need to add any extra styling to use them.

You can customize the styling of Shadcn components, including the Button component, by adding or removing variants that you won't use. This is done by opening the component's source code in the components/ui directory.

The Button component has multiple variants, including default, destructive, outline, secondary, ghost, and link, as well as different sizes to choose from. You can add your own custom variants to the component by pasting in the styling for the custom button.

One of the variants I added was called myButton, which is the custom variant I created by pasting in the styling from our earlier example. This custom variant can be used in your project just like any other variant.

You can use the custom myButton variant in your project by importing the Button component and then selecting the myButton variant when using it.

The Feed Item Card is a crucial component in our example app, responsible for rendering feed items in a visually appealing way. It takes two props: item (the feed item) and knockFeed.

This component does a lot of heavy lifting, extracting different blocks attached to the feed item, like the body, which is the message template we created as part of our workflow. It also loops through the item's actors and creates the heading.

To render the date, the Feed Item Card uses the toLocaleDateString function and the item.insertedAt property. This function helps format the date in a user-friendly way.

The Feed Item Card also handles message engagement statuses by conditionally rendering different buttons based on whether the item has been read or not. This is achieved by passing the knockFeed client into the component, allowing us to attach onClick handlers to specific methods on knockFeed.

Here's a breakdown of the actions the Feed Item Card performs:

You can use pnpm, bun, or yarn to install shadcn/ui. No flags are needed.

Follow the instructions in the installation guide for the chosen package manager.

To resolve peer dependency issues, you can run the command with a flag.

The process for adding components is the same regardless of the package manager used.

In Next.js, you can use the @ symbol to import components and libraries from specific directories. For example, @/components/whatever will look for the component at ROOT => src/components/whatever. This is useful for organizing your code and avoiding conflicts with other imports.

If you're using a config that's not set up correctly, you might end up looking for imports in the wrong place. For instance, if you write import { cn } from "@/lib/utils, it will look for it at ./@/components/ui/button/@/lib/utils, which is not found.

This can be frustrating, especially if you're not sure where to look. But with the right config and understanding of how imports work in Next.js, you can avoid these issues and keep your code organized and efficient.

Here's a quick rundown of how to set up your imports correctly:

You can use the useState hook to create local state variables for your component. This is exactly what we did in the ActivityFeed component.

To fetch data, you need to make network calls using the knockFeed client. We used the knockFeed client to load the initial state of our feed and listen for updates.

The useEffect hook is used to ask the knockFeed client to listen for real-time updates. Inside the useEffect hook, we're asking the knockFeed client to listen for real-time updates.

You need to create a function to fetch the feed initially. We created a function to fetch the feed initially.

To reconcile updates with our local state, we need to add event listeners to the knockFeed. The Knock feed does a good job of keeping track of its own internal state.
