Installing the Golden Layout Symphony
To begin orchestrating your React layouts with Golden Layout, you’ll need to install the library. You can do this using either npm or yarn:
# Using npm
npm install golden-layout
# Using yarn
yarn add golden-layout
Once installed, you’re ready to start composing your layout masterpiece.
Composing Your First Golden Layout
Let’s start by creating a basic layout with Golden Layout in a React application. First, we’ll set up the necessary imports and create a simple component structure.
Setting the Stage
import React, { useRef, useEffect } from 'react';
import { GoldenLayout, LayoutConfig } from 'golden-layout';
import 'golden-layout/dist/css/goldenlayout-base.css';
import 'golden-layout/dist/css/themes/goldenlayout-dark-theme.css';
const MyLayout: React.FC = () => {
const layoutRef = useRef<GoldenLayout | null>(null);
const containerRef = useRef<HTMLDivElement>(null);
useEffect(() => {
if (containerRef.current) {
const layout = new GoldenLayout(containerRef.current);
layoutRef.current = layout;
// We'll add our configuration here
layout.init();
}
}, []);
return <div ref={containerRef} style={{ width: '100%', height: '600px' }} />;
};
export default MyLayout;
In this setup, we’re creating a container for our layout and initializing Golden Layout within a useEffect hook. The containerRef is used to provide Golden Layout with the DOM element it should render into.
Arranging the Components
Now, let’s add some components to our layout. We’ll create a configuration that splits the screen into two columns, with the right column further divided into two rows.
const config: LayoutConfig = {
root: {
type: 'row',
content: [
{
type: 'component',
componentName: 'example',
componentState: { label: 'A' },
title: 'Component A',
width: 30
},
{
type: 'column',
content: [
{
type: 'component',
componentName: 'example',
componentState: { label: 'B' },
title: 'Component B'
},
{
type: 'component',
componentName: 'example',
componentState: { label: 'C' },
title: 'Component C'
}
]
}
]
}
};
layout.loadLayout(config);
This configuration creates a layout with three components: A, B, and C. Component A takes up 30% of the width on the left, while B and C are stacked vertically on the right.
Bringing Components to Life
To make our layout functional, we need to register the components we’ve defined. Let’s create a simple example component and register it with Golden Layout.
const ExampleComponent: React.FC<{ label: string }> = ({ label }) => {
return <div>{`I am component ${label}`}</div>;
};
layout.registerComponent('example', ExampleComponent);
By registering the component, we’re telling Golden Layout how to render our example components when they’re referenced in the configuration.
Advanced Compositions with Golden Layout
Now that we’ve got the basics down, let’s explore some more advanced features of Golden Layout that can add depth and interactivity to your React applications.
Conducting Responsive Layouts
Golden Layout can adapt to different screen sizes, making it perfect for responsive designs. Let’s modify our layout to be responsive:
const responsiveConfig: LayoutConfig = {
settings: {
responsiveMode: 'always'
},
dimensions: {
minItemWidth: 200,
minItemHeight: 200
},
content: [
{
type: 'row',
content: [
{
type: 'component',
componentName: 'example',
componentState: { label: 'Responsive A' },
title: 'Responsive Component A'
},
{
type: 'component',
componentName: 'example',
componentState: { label: 'Responsive B' },
title: 'Responsive Component B'
}
]
}
]
};
layout.loadLayout(responsiveConfig);
This configuration enables responsive mode and sets minimum dimensions for items. The layout will automatically adjust as the screen size changes.
Orchestrating Popout Windows
One of Golden Layout’s standout features is the ability to create popout windows. Let’s add this functionality to a component:
const PopoutComponent: React.FC<{ glContainer: any }> = ({ glContainer }) => {
const handlePopout = () => {
glContainer.parent.popout();
};
return (
<div>
<button onClick={handlePopout}>Popout</button>
<p>Click to open in a new window!</p>
</div>
);
};
layout.registerComponent('popout', PopoutComponent);
Now you can add this component to your layout configuration, and users will be able to pop it out into a separate window.
Composing with Virtual Components
Virtual components are particularly useful when working with frameworks like React. They allow you to create components that Golden Layout manages without directly manipulating the DOM.
const VirtualComponent: React.FC = () => {
return <div>I'm a virtual component!</div>;
};
layout.createComponentCreator(VirtualComponent, 'virtual');
const virtualConfig: LayoutConfig = {
root: {
type: 'component',
componentName: 'virtual',
title: 'Virtual Component'
}
};
layout.loadLayout(virtualConfig);
This approach gives you more control over how your React components are rendered within the Golden Layout structure.
