Use Material UI V5 With Typescript

Introduction

Hello everyone! In this article, we are going to talk about Material UI V5 with Typescript. If you are a React developer, you must have heard of Material UI. It is one of the most popular React UI component libraries out there. On the other hand, Typescript is a superset of JavaScript that provides static typing and improves the developer experience.

Material UI V5 is the latest version of Material UI, where the whole library is rewritten from scratch to support new features and improvements. It is faster, more customizable, and provides a more natural way of writing CSS styles.

So, what happens if we integrate Typescript with Material UI V5? In this article, we are going to explore the benefits, how to integrate Typescript, and how to use Material UI V5 with Typescript.

What’s new in Material UI V5?

Before diving into using Material UI with Typescript, let’s talk about some of the new features of Material UI V5. Material UI V5 is a major release, and it comes with many new features and improvements. Let’s have a look at some of them.

1. Faster and Lightweight

In Material UI V5, the library is rewritten from scratch, which means it has better performance and is lighter than its previous versions. Also, the new version comes with a better packaging system, which means you can import only the components that you need and use.

2. Improved Customization

Customization is one of the essential parts of any UI library, and Material UI is known for providing extreme customization capabilities. Material UI V5 takes it one step further by introducing a new CSS engine called “Emotion.” It gives you better control over CSS styles and improves the customization experience.

3. New Components

Material UI V5 comes with many new components, such as Autocomplete, Rating, and ToggleButton. These components are highly customizable and provide a great user experience.

4. Improved Accessibility

Accessibility is critical for any UI library, and Material UI V5 makes it easier to make your application accessible. It provides an accessibility module that helps you make your components more accessible.

Integrating Typescript with Material UI V5

Now that we have explored the new features of Material UI V5 let’s discuss the benefits of integrating Typescript with Material UI V5.

Benefits of using Typescript in Material UI

Typescript brings many benefits to any JavaScript project, and Material UI is no exception. Here are some benefits of using Typescript in Material UI.

1. Static Typing

One of the major benefits of using Typescript with Material UI is static typing. Typescript provides type checking, which helps you catch bugs and improve your code quality. When you use Material UI components in your project, you can pass props and state to these components. In the absence of proper type checking, it is easy to misspell, mistype, or misuse these props and state. Typescript ensures that you use these components correctly and improves the robustness of your code.

2. Better IDE Support

Typescript provides better IDE support than JavaScript. Modern IDEs such as VS Code, Webstorm, or Atom have built-in support for Typescript. They provide better code completion, type checking, and debugging capabilities. When you use Material UI with Typescript, you get better IDE support, which improves your productivity and reduces development time.

3. Improved Code Readability

Typescript provides better code readability than JavaScript. When you use types and interfaces in Typescript, your code becomes easier to read and understand. Also, when you work with Material UI components, the types and interfaces act as documentation for these components and improve your code’s readability.

Steps to integrate Typescript with Material UI V5

Now that we have discussed the benefits let’s dive into the steps to integrate Typescript with Material UI V5.

Step 1: Create a new React project with Typescript

The first step is to create a new React project with Typescript. You can use create-react-app to create a new project.

npx create-react-app my-app --template typescript

Step 2: Install Material UI

The second step is to install Material UI. You can install Material UI using npm or yarn.

npm install @material-ui/core

or

yarn add @material-ui/core

Step 3: Install Typings

The third step is to install typings for Material UI to get type definitions. You can install typings using npm or yarn.

npm install @types/material-ui

or

yarn add @types/material-ui

Step 4: Import Material UI Components

The last step is to import Material UI components and use them in your project.

import { Button } from '@material-ui/core';

function MyButton() {
  return (
    <Button variant="contained" color="primary">
      Click Me
    </Button>
  );
}

Best practices for using Typescript in Material UI

Let’s discuss some best practices for using Typescript with Material UI.

1. Define Interfaces and Types

When you use Material UI components in your project, it is recommended to define interfaces and types for props and state. It improves the code’s readability and ensures correct usage of these components.

interface MyButtonProps {
  text: string;
  onClick: () => void;
}

function MyButton(props: MyButtonProps) {
  return (
    <Button variant="contained" color="primary" onClick={props.onClick}>
      {props.text}
    </Button>
  );
}

2. Use Theme Provider

Material UI provides Theme Provider, which allows you to customize the look and feel of Material UI components. When you use Theme Provider with Typescript, it is recommended to define the theme interface to get better type checking.

declare module '@material-ui/core/styles/createMuiTheme' {
  interface Theme {
    myCustomThemeValue: string;
  }
  interface ThemeOptions {
    myCustomThemeValue?: string;
  }
}

const theme = createMuiTheme({
  myCustomThemeValue: '#000',
});

function MyApp() {
  return (
    <ThemeProvider theme={theme}>
      <MyButton text="Click Me" onClick={() => alert('Button Clicked!')} />
    </ThemeProvider>
  );
}

3. Use JSS for Styling

Material UI provides JSS (JavaScript Style Sheets) for styling. JSS is a CSS in JS solution that allows you to write CSS styles in JavaScript. When you use JSS with Typescript, it is recommended to define the styles interface to get better type checking.

```
const useStyles =
makeStyles((theme: Theme) => createStyles({
  myButton: {
    color: theme.palette.primary.contrastText,
    backgroundColor: theme.palette.primary.main,
    '&:hover': {
      backgroundColor: theme.palette.primary.dark,
    },
  },
}));

interface MyButtonProps {
  text: string;
  onClick: () => void;
}

function MyButton(props: MyButtonProps) {
  const classes = useStyles();

  return (
    <Button className={classes.myButton} onClick={props.onClick}>
      {props.text}
    </Button>
  );
}
```

Examples of using Material UI V5 with Typescript

Now that we have seen how to integrate Typescript with Material UI V5 and some best practices, let’s dive into some examples of using Material UI V5 with Typescript.

1. Using Autocomplete Component

The Autocomplete component is one of the new components in Material UI V5. It provides a great user experience and is highly customizable. Let’s see how we can use the Autocomplete component with Typescript.

interface Option {
  value: string;
  label: string;
}

const options: Option[] = [
  { value: 'apple', label: 'Apple' },
  { value: 'banana', label: 'Banana' },
  { value: 'cherry', label: 'Cherry' },
  { value: 'orange', label: 'Orange' },
];

interface AutocompleteProps {
  label: string;
  options: Option[];
}

function MyAutocomplete(props: AutocompleteProps) {
  const { label, options } = props;

  return (
    <Autocomplete
      options={options}
      getOptionLabel={(option: Option) => option.label}
      renderInput={(params) => <TextField {...params} label={label} />}
    />
  );
}

2. Using Rating Component

The Rating component is another new component in Material UI V5. It provides a star rating feature and is highly customizable. Let’s see how we can use the Rating component with Typescript.

interface RatingProps {
  name: string;
}

function MyRating(props: RatingProps) {
  const { name } = props;
  const [value, setValue] = useState<number | null>(2);

  return (
    <Rating
      name={name}
      value={value}
      onChange={(event: React.ChangeEvent<{}>, newValue: number | null) => {
        setValue(newValue);
      }}
    />
  );
}
