Adding Components to React Without a Rebuild

Ah, the vast ocean of web development! It's where the waves of innovation never cease to roll. Among its many ships, React has carved a niche for being both sturdy and flexible. However, a common quill in the sails is the need to rebuild the entire ship whenever a new cannon (component) is added.

But what if there was a way to add firepower without returning to the dry dock?

This post researches a crafty method to add a component to a React application without invoking a rebuild or updating any library.

Imagine a bustling port representing your React application. Each dock is a component, contributing to the port's functionality. Now, you have a new vessel, an external component, ready to dock, but the idea of disturbing the existing setup for its accommodation seems tedious. The solution? A smooth integration without a rebuild!

The Independent Vessel: Server-Side Component

Start by hosting the new component on a separate server. Build and bundle it independently, ensuring it's ready for the high seas on its own. This independent vessel can then be called upon when needed.

// Hosted at https://external-component-server.com/component.js
const MyComponent = () => {
  return <div>Hello from the external component</div>;
};
window.MyExternalComponent = MyComponent;

Navigating the Waters: Dynamic Script Loading

With the external component ready, it's time to navigate the waters. Utilize a dynamic script loading strategy to fetch and render the new component at runtime. This way, the new vessel sails and docks smoothly without disturbing the existing setup.

function loadComponent(src) {
  return new Promise((resolve, reject) => {
    const script = document.createElement('script');
    script.src = src;
    script.async = true;
    script.onload = () => { resolve(window.myExternalComponent); };
    script.onerror = () => { reject('Failed to load the component'); };
    document.body.appendChild(script);
  });
}

async function renderComponent() {
  try {
    const Component = await loadComponent('https://external-component-server.com/component.js');
    ReactDOM.render(<Component />, document.getElementById('component-container'));
  } catch (error) {
    console.error(error);
  }
}

renderComponent();

The Grand Reception: Style Injection

A vessel arriving at a port is a spectacle. Ensure the new component matches the grandeur by dynamically injecting the necessary styles hosted on a CDN.

const link = document.createElement('link');
link.rel = 'stylesheet';
link.href = 'https://cdn.example.com/component-styles.css';
document.head.appendChild(link);

Engaging in Trade: Component Communication

Establishing a communication channel between your port and the new vessel is crucial for seamless interaction. Utilize Custom Events or postMessage for a dialogue between the existing application and the new component.

The journey of dynamically introducing a new component without a rebuild is like adding a fresh narrative to an already intriguing novel. It enriches the existing story while keeping the readers (users) engaged.
