Introduction
Mantine is a lightweight and easy-to-use library that provides a wide range of components and hooks for building high-performance web applications. It is built on top of React and TypeScript, making it a great choice for building modern web applications.
Setting Up Mantine UI
Mantine can be used with React,Refine, Next, Vite, Remix, and Gatsby.
In this article, we will be using Next. To install Mantine in a Next application follow the detailed steps below:
npx create-next-app@latest --typescript
Mantine has a list of packages that can be used in your project this is what they look like:
By selecting anyone you could add them to the installation process:
npm install @mantine/core @mantine/hooks
Now let's setup MantineProvider in our application:
Set up MantineProvider
In your Next.js application, you'll want to wrap your entire app with the MantineProvider component. You can do this by creating a _app.js file in your pages directory if it doesn't already exist, and then import MantineProvider and wrap your Component with it. Here's an example of what your _app.js file might look like:
import React from "react";
import { MantineProvider } from "@mantine/core";
import "../styles/globals.css"; // Import your global styles here
function MyApp({ Component, pageProps }) {
return (
<MantineProvider>
<Component {...pageProps} />
</MantineProvider>
);
}
export default MyApp;
Start Using Mantine Components
You can now start using Mantine components in your Next.js application. For example, create a new component in the components directory and use Mantine components inside it:
import React from "react";
import { Button } from "@mantine/core";
function MyComponent() {
return <Button>Hello, Mantine!</Button>;
}
export default MyComponent;
Then, import and use MyComponent in your pages:
import React from "react";
import MyComponent from "../components/MyComponent";
function Home() {
return (
<div>
<h1>Welcome to My Next.js App with Mantine!</h1>
<MyComponent />
</div>
);
}
export default Home;
Run Your Next.js Application
Finally, run your Next.js application to see the Mantine components in action:
npm run dev
Your Next.js application with Mantine is now set up and ready to go! You can continue to explore Mantine's Hooks and components and integrate them into your project as needed
Mantine UI Hooks
Hooks were introduced to change the way React components are built as they are meant to simplify component logic. They allow you to use state and other React features in functional components without writing a class. This makes the code cleaner and easier to understand.
With hooks, the logic can be reused (like fetching data or subscribing to external events) can be encapsulated in custom hooks. These custom hooks can be reused across different components and even different projects, promoting reusability.
Mantine as a React component Library utilizes custom hooks to manage state, manipulate the DOM, and handle design-related functionalities. These custom hooks are designed to simplify complex tasks, such as managing form state, handling user interactions, managing modals, and more.
Let’s explore a few of these hooks;
The useClipboard()
The useClipboard hook is a custom hook worth of mention. This hook simplifies working with the clipboard by providing an easy-to-use interface. It accepts an options argument, which defines the timeout duration (in milliseconds) for the copied status. If the copy function is called within the specified timeout, the copied value will be true, indicating that the copy operation was successful within that timeframe.
Here's the TypeScript definition of the useClipboard hook for reference:
function useClipboard(options: { timeout: number } = { timeout: 2000 }): {
copy: (valueToCopy: any) => void;
reset: () => void;
error: Error;
copied: boolean;
};
Here's a breakdown of the properties returned by the useClipboard() hook: copy: (valueToCopy: any) => void: This is a function that you can call with the value you want to copy to the clipboard. For example, if you want to copy a string, you would call copy('text to copy').
reset: () => void: This function clears the timeout and resets the copied value. You can use this function if you want to reset the copied status manually.
error: Error: This property contains an Error object if something goes wrong during the copying process. For example, if the browser does not support the clipboard API or if there are other issues, the error property will be populated with an error object.
copied: boolean: This property is a boolean value that indicates whether the copy function was called less than options.timeout milliseconds ago. If it was, copied is true; otherwise, it is false. This property is useful for showing feedback to the user, such as displaying a message like "Copied!" after a successful copy operation.
Let’s use this hook to simplify clipboard interactions in our React application:
import React from "react";
import { useClipboard } from "@mantine/hooks";
import FileCopyIcon from "@mui/icons-material/FileCopy";
const App: React.FC = () => {
const items = ["https://refine.dev/blog/"];
const clipboard = useClipboard({ timeout: 1500 });
return (
<div>
<ul>
{items.map((description, index) => (
<li key={index}>
<button onClick={() => clipboard.copy(description)}>
{clipboard.copied ? <span>Copied! </span> : <span>Copy Link </span>}
<FileCopyIcon />
</button>
</li>
))}
</ul>
</div>
);
};
export default App;
let's take a look at what it looks like:
UseWindowScroll()
Building a web page involves making it as interactive as possible and making ease of use a top priority. If you are conversant with blogs, especially those bulky ones, where you must have scrolled a lot and you just want to go back to the top of the web page, scrolling backup becomes stressful.
As developers, we prioritize enhancing user experience, and this is where the useWindowScroll() hook comes into play. This hook seamlessly interacts with the DOM, providing access to the current scroll position and enabling smooth scrolling to a specific location on the page.
This is what the actual implementation looks like:
import { useWindowScroll } from "@mantine/hooks";
import { Button, Text, Group } from "@mantine/core";
export default function App() {
const [scroll, scrollTo] = useWindowScroll();
return (
<Group className="center">
<Button onClick={() => scrollTo({ y: document.body.scrollHeight })}>Scroll to Bottom</Button>
<Text>//Long Text</Text>
<Button onClick={() => scrollTo({ y: 0 })}>Scroll to top</Button>
</Group>
);
}
Use-Disclosure
The useDisclosure() hook is our last tool on the list and it deserves recognition. useDisclosure() simplifies managing boolean state in React applications. It's particularly useful for handling components like modals, popovers, and other UI elements that need to be conditionally displayed or hidden based on user interactions.
Open, Close, and Toggle Handlers hooks provide intuitive open(), close(), and toggle() handlers. These functions abstract away the complexities of managing state transitions, making it easier to control when a component should be displayed or hidden.
The hook accepts optional onOpen and onClose callbacks. These callbacks enable you to execute specific actions or logic when the component is opened or closed. For instance, you could perform additional tasks or trigger animations when a modal opens or closes.
Let’s look at how this is implemented:
import React from "react";
import { useDisclosure } from "@mantine/hooks";
import { Modal, Button, Group, Col, Container } from "@mantine/core";
export default function App() {
const [opened, { open, close }] = useDisclosure(false);
return (
<div>
<Modal opened={opened} onClose={close} title="We use cookies" centered size="sm">
<p>This website uses cookies to ensure you get the best experience on our website.</p>
<Container mt={4}>
<Group position="right">
<Button color="gray" onClick={close}>
Decline
</Button>
<Button variant="filled" color="blue" onClick={close}>
Accept
</Button>
</Group>
</Container>
</Modal>
<Button onClick={open}>Click here to advance</Button>
</div>
);
}
let's take a look at what it looks like:

Mantine's form components are designed for ease of use and customization. For instance, the TextInput component allows developers to create input fields with various styles, validations, and placeholder texts. The Form component simplifies form management, elegantly handling form submissions, validations, and error messages.
import { TextInput, Checkbox, Button, Group, Box } from "@mantine/core";
import { useForm } from "@mantine/form";
function App() {
const form = useForm({
initialValues: {
email: "",
termsOfService: false,
},
validate: {
email: (value) => (/^\S+@\S+$/.test(value) ? null : "Invalid email"),
},
});
return (
<Box maw={340} mx="auto">
<form onSubmit={form.onSubmit((values) => console.log(values))}>
<TextInput
withAsterisk
label="Email"
placeholder="please provide your valid @email.com"
{...form.getInputProps("email")}
/>
<Checkbox
mt="md"
label="I agree to read Refine's Blog always"
{...form.getInputProps("termsOfService", { type: "checkbox" })}
/>
<Group justify="flex-end" mt="md">
<Button type="submit">Submit</Button>
</Group>
</form>
</Box>
);
}
export default App;
Navigation: Mantine offers various navigation components, such as Menu, Tab, and Pagination, enhancing the user experience. Tabs enable organized content switching, while Paginations Display active pages and navigate between multiple pages. Menus and Dropdowns simplify complex navigational hierarchies.
import { Tabs } from "@mantine/core";
function App() {
return (
<Tabs defaultValue="first">

</Tabs.List>
</Tabs>
);
}
export default App;
import { Pagination } from "@mantine/core";
export default function App() {
return <Pagination total={36} />;
}
import { Menu, Button, Text, rem } from "@mantine/core";
import {
IconSettings,
IconSearch,
IconPhoto,
IconMessageCircle,
IconTrash,
IconArrowsLeftRight,
} from "@tabler/icons-react";
export default function App() {
return (
<Menu shadow="md" width={200}>
<Menu.Target>
<Button>Main menu</Button>
</Menu.Target>
<Menu.Dropdown>
<Menu.Label>Application</Menu.Label>
<Menu.Item leftSection={<IconSettings style={{ width: rem(14), height: rem(14) }} />}>blog</Menu.Item>

<Menu.Item leftSection={<IconSearch style={{ width: rem(14), height: rem(14) }} />}>Search</Menu.Item>
<Menu.Divider />
</Menu.Dropdown>
</Menu>
);
}
Notifications Mantine's notifications and modals provide user feedback and interactive dialogues. Notifications offer informative or alerting messages to users, while modals and popovers facilitate interactive tasks, ensuring a seamless user experience. Let’s look at how this is implemented below:
import { IconX, IconCheck } from "@tabler/icons-react";
import { Notification, rem } from "@mantine/core";
function App() {
const xIcon = <IconX style={{ width: rem(20), height: rem(20) }} />;
const checkIcon = <IconCheck style={{ width: rem(20), height: rem(20) }} />;
return (
<>
<Notification icon={xIcon} color="blue" title="Hey!">
Got to Refine immediately
</Notification>
<Notification icon={checkIcon} color="teal" title="All good!" mt="md">
Everything should be fine!!
</Notification>
</>
);
}
export default App;
import { useDisclosure } from "@mantine/hooks";
import { Modal, Button } from "@mantine/core";
import { TextInput, Checkbox, Group, Box } from "@mantine/core";
import { useForm } from "@mantine/form";
export default function App() {
const [opened, { open, close }] = useDisclosure(false);
const form = useForm({
initialValues: {
email: "",
termsOfService: false,
},
validate: {
email: (value) => (/^\S+@\S+$/.test(value) ? null : "Invalid email"),
},
});
return (
<>
<Modal opened={opened} onClose={close} title="Refine form" centered>
<Box maw={340} mx="auto">
<form onSubmit={form.onSubmit((values) => console.log(values))}>
<TextInput
withAsterisk
label="Email"
placeholder="please provide your valid @email.com"
{...form.getInputProps("email")}
/>
<Checkbox
mt="md"
label="I agree to read Refine's Blog always"
{...form.getInputProps("termsOfService", { type: "checkbox" })}
/>
<Group>
<Button className="BTN" onClick={close} type="submit">
Submit
</Button>
</Group>
</form>
</Box>
</Modal>
<Button onClick={open}>Open centered Modal</Button>
</>
);
}
Theming and Customization Mantine allows extensive theming and customization, allowing developers to align the UI with the brand identity. The MantineProvider component wraps the entire application, providing a context for theme customization. Themes include color schemes, typography, spacing, and other design elements, enabling a consistent look and feel across components.
import { MantineProvider, Container, TextInput } from "@mantine/core";
function App() {
return (
<MantineProvider theme={{ colorScheme: "dark" }}>
<Container>
<TextInput label="Dark Mode Input" placeholder="Enter text" />
</Container>
</MantineProvider>
);
}
Conclusion
In the fast-paced world of web development, as web developers, we only have a limited time to deliver tasks unless it’s a personal project for which a deadline is a good practice. having tools that will help meet deadlines and also help in producing visually appealing interfaces is detrimental. Mantine has proven to be one of the go-to UI libraries for this.
