Getting Started with Mitosis: Creating a Cross-Framework Design System

In the ever-evolving landscape of web development, maintaining consistency across various frameworks and platforms can be a daunting task. This is where design systems come into play, providing a centralized set of guidelines and components that ensure a cohesive user experience.

Enter Mitosis, a revolutionary tool that empowers developers to build cross-framework design systems with ease. By leveraging a single source of truth, Mitosis enables you to create components that seamlessly adapt to different frameworks like React, Vue, Svelte, and even vanilla JavaScript.

Why Choose Mitosis?

Mitosis offers several compelling reasons for choosing it as your design system foundation:

Cross-Framework Compatibility:
Write once, use everywhere. Mitosis allows you to create components that work across multiple frameworks, reducing redundancy and development time.
Simplified Development:
Focus on building the design system itself, not on adapting it to different frameworks. Mitosis handles the framework-specific implementation details.
Enhanced Maintainability:
Changes made to the source code automatically propagate to all target frameworks, ensuring consistency and reducing the risk of errors.
Seamless Integration:
Mitosis integrates seamlessly with popular tools and libraries, making it easy to incorporate into existing projects.

Setting Up Your Mitosis Environment

Let's dive into the practical aspects of using Mitosis. Here's how you can get started:

Installation

Start by installing Mitosis globally using npm or yarn:

npm install -g mitosis

Creating a Project

Mitosis provides a convenient command-line tool for project creation:

mitosis create my-design-system

This command generates a basic project structure with essential files and configurations.

Building Your First Component

Let's create a simple button component within your Mitosis project:

// src/components/Button.tsx
import { html, css, state } from '@mitosis-design/core';

export const Button = (props: {
text: string;
onClick: () => void;
}) => {
const [isPressed, setIsPressed] = state(false);

return html`
    <button =="" class="${css` background-color: ${isPressed ? 'blue' : 'lightblue'}; color: white; border: none; padding: 10px 20px; border-radius: 5px; cursor: pointer; `}" onclick="${()"> {
            setIsPressed(true);
            props.onClick();
        }}
        onmouseleave=${() =&gt; setIsPressed(false)}
    &gt;
        ${props.text}
    </button>
`;

};

This code defines a button component using Mitosis's template language, which combines JSX-like syntax with a powerful state management system. You can create components with different frameworks in mind using a single source of truth.

Generating Framework-Specific Implementations

Mitosis allows you to generate framework-specific code for your components with ease. Let's generate React and Vue versions of our Button component:

mitosis generate react src/components/Button.tsx 
mitosis generate vue src/components/Button.tsx

These commands will generate React and Vue components in the corresponding folders, making them ready for use within your respective projects.

Example: Building a Reusable Button

Let's illustrate how Mitosis simplifies the process of building reusable components across frameworks. We'll create a simple "Primary Button" component that can be customized with different text and sizes.

// src/components/PrimaryButton.tsx
import { html, css, state } from '@mitosis-design/core';


export const PrimaryButton = (props: {

    text: string;

    size: 'small' | 'medium' | 'large';

}) => {

    const [isPressed, setIsPressed] = state(false);
return html`
    <button =="" class="${css` background-color: blue; color: white; border: none; padding: ${props.size === 'small' ? '8px 16px' : props.size === 'medium' ? '12px 24px' : '16px 32px'}; border-radius: 5px; cursor: pointer; font-size: ${props.size === 'small' ? '14px' : props.size === 'medium' ? '16px' : '18px'}; `}" onclick="${()"> {
            setIsPressed(true);
            props.onClick &amp;&amp; props.onClick();
        }}
        onmouseleave=${() =&gt; setIsPressed(false)}
    &gt;
        ${props.text}
    </button>
`;


};

This component allows you to customize the button's size and text. You can generate React and Vue versions of this component as well, ensuring consistent usage across your projects.

Integration with Your Projects

Once you've generated framework-specific code for your components, you can easily integrate them into your projects:

React

Import the React component and use it as you would any other React component:



import React from 'react';

import { PrimaryButton } from './components/PrimaryButton.react.js';

function App() {

  return (

    


      

    

  );

}

export default App;

Vue

Import the Vue component and register it globally or locally:



import { createApp } from 'vue';

import App from './App.vue';

import PrimaryButton from './components/PrimaryButton.vue';

const app = createApp(App);


app.component('PrimaryButton', PrimaryButton);


app.mount('#app');

Beyond Basic Components

Mitosis goes beyond basic components. You can also build complex UI elements like modals, dropdowns, and more, ensuring consistency and a seamless user experience across your applications.
