Adding Stunning Gradients to Your React Application with Visx
Written on
Chapter 1: Introduction to Visx
Visx is a powerful library that simplifies the process of incorporating graphics into your React applications. In this guide, we will explore how to utilize it to seamlessly integrate gradients into your React project.
Section 1.1: Installing Necessary Packages
To begin, we need to install a few essential modules. You can initiate the process by running the following command in your terminal:
npm i @visx/gradient @visx/responsive @visx/shape
Section 1.2: Creating Gradients
Next, we will create our gradients using the following code snippet:
import React from "react";
import { Bar } from "@visx/shape";
import {
GradientDarkgreenGreen,
GradientLightgreenGreen,
GradientOrangeRed,
GradientPinkBlue,
GradientPinkRed,
GradientPurpleOrange,
GradientPurpleRed,
GradientTealBlue,
RadialGradient,
LinearGradient
} from "@visx/gradient";
const defaultMargin = {
top: 0,
left: 0,
right: 0,
bottom: 0
};
const Gradients = [
GradientPinkRed,
({ id }) => <RadialGradient id={id} from="#55bdd5" to="#4f3681" r="80%" />,
GradientOrangeRed,
GradientPinkBlue,
({ id }) => (
<LinearGradient id={id} from="#351CAB" to="#621A61" rotate="-45" />),
GradientLightgreenGreen,
GradientPurpleOrange,
GradientTealBlue,
GradientPurpleRed,
GradientDarkgreenGreen
];
In this snippet, we import the gradient components from the @visx/gradient module and organize them in the Gradients array. You can directly use these components or create a function that returns a RadialGradient for a radiant effect.
Subsection 1.2.1: Rendering the Gradients
The next step is to render the gradients. The Example component is designed to handle this:
function Example({ width, height, margin = defaultMargin }) {
const numColumns = width > 600 ? 5 : 2;
const numRows = Gradients.length / numColumns;
const columnWidth = Math.max(width / numColumns, 0);
const rowHeight = Math.max((height - margin.bottom) / numRows, 0);
return (
<svg width={width} height={height}>
{Gradients.map((Gradient, index) => {
const columnIndex = index % numColumns;
const rowIndex = Math.floor(index / numColumns);
const id = visx-gradient-demo-${index}-${rowIndex}${columnIndex};
return (
<React.Fragment key={id}>
<Gradient id={id} />
<Bar
fill={url(#${id})}
x={columnIndex * columnWidth}
y={rowIndex * rowHeight}
width={columnWidth}
height={rowHeight}
stroke="#ffffff"
strokeWidth={8}
rx={14}
/>
</React.Fragment>
);
})}
</svg>
);
}
In this component, we utilize Gradients.map to render each gradient, separated by a white bar using the Bar component.
