Integrating Million.js with Vite: Supercharging Your React Projects

TLDR; React has never been this optimized before well, still not at 100%.


3 min read

In this blog, we will explore how to integrate Million.js, the latest performance-focused JavaScript library, into an existing Vite project. Million.js has made a significant impact by providing a blazing-fast, lightweight alternative to React, making it a compelling choice for modern web developers.

1. Introduction to Million.js

Million.js is a high-performance, lightweight virtual DOM library designed for building fast, efficient web applications. It offers an excellent alternative to other popular web libraries like React, especially when it comes to performance.

Some key features of Million.js include:

  • A small bundle size, weighing in at just a few kilobytes

  • An optimized virtual DOM implementation for high-speed rendering

  • A simple, intuitive API for building user interfaces

  • Support for both functional and class components

2. Why Vite?

Vite is a next-generation frontend build tool and development server designed to be faster and more efficient than traditional bundlers like Webpack. It offers a number of benefits, such as:

  • Lightning-fast development server startup times

  • Efficient, on-demand transpilation and bundling

  • Out-of-the-box support for modern web technologies, including ES modules and dynamic imports

  • Simple, easy-to-use configuration and plugin system

Combining the performance advantages of Million.js with the power and flexibility of Vite makes for a winning combination, enabling developers to create high-performance web applications with ease.

3. Setting Up the Vite Project

Before integrating Million.js, ensure that your Vite project is properly set up and configured. To do this, follow these steps:

  1. Install Vite globally on your system using npm or Yarn:

    npm install -g create-vite

  2. Create a new Vite project:

    create-vite my-vite-project

  3. Install the necessary dependencies:

    cd my-vite-project && npm install

4. Integrating Million.js

Now that your Vite project is set up, it's time to integrate Million.js. Follow these steps:

  1. Install Million.js as a dependency:

    npm install million

  2. Create a new file named million.config.js In the root of your project and add the following content:

     import { m } from 'million';
     export function render(element, container) {
       m.render(container, element);
  3. Update your index.js file to import the render function and use it to render your app's root component:

     import { render } from './million.config.js';
     import App from './App.js';
     render(App, document.getElementById('app'));

    5. Harnessing Million.js Performance

    Now that you've migrated your components to Million.js, you can take full advantage of its performance optimizations. Here are some tips to help you get the most out of Million.js:

    • Use keys for lists: Like React, Million.js uses keys to optimize the rendering of lists. Always include a unique key for each item in a list to ensure optimal rendering performance.

    • Minimize component state updates: Updating a component's state triggers a re-render, which can impact performance. To minimize unnecessary re-renders, only update the state when necessary, and consider using the shouldComponentUpdate lifecycle method for class components to prevent unwanted updates.

    • Optimize render functions: Keep your components' render functions simple and efficient, avoiding unnecessary computations or complex logic. This will help ensure that your components render quickly and smoothly.

    • Use functional components where possible: Functional components tend to be faster and more memory-efficient than class components, so use them whenever possible.

      6. Conclusion

      In this blog, we've explored the steps required to integrate Million.js into an existing Vite project and migrate from React to Million.js. By combining the performance benefits of Million.js with the power and flexibility of Vite, you can create high-performance web applications that load quickly and run smoothly.

      As you migrate your existing projects to Million.js, keep in mind that while the syntax and API are slightly different from React, the concepts remain similar. With some practice and attention to performance optimizations, you'll be able to harness the full potential of Million.js and create blazing-fast web applications your users will love!
