The Elastic UI (EUI) framework is a design library that has become an essential tool for developers and designers alike. It's a comprehensive suite of UI components tailored for quickly building functional user interfaces that adhere to modern design standards.
The EUI framework began as a solution to provide reusable UI components for Elastic's internal products. Still, it has since grown into a widely adopted framework powering a wide array of applications beyond Elastic itself.
The journey of the Elastic UI framework began with the goal of maintaining brand consistency across the Elastic Stack. The framework was designed to integrate EUI into a React app, ensuring developers could efficiently leverage tested code to build web layouts. With the EUI framework, EUI became synonymous with low-level consistency and high-quality unit test coverage.
To kickstart your project with Elastic UI, you must add it as a dependency using a package manager like Yarn. The EUI framework distributes UI React components ready to be integrated into your project. Here's a basic example of how to install Elastic UI:
1yarn add @elastic/eui 2
Remember, Elastic UI has peer dependencies that must be installed, especially when starting a new project. These include libraries like @elastic/datemath, @emotion/react, and moment, among others.
Once installed, setting up your application to use Elastic UI is straightforward. During the transition to CSS-in-JS usage, Elastic UI requires the EuiProvider and the compiled CSS to be imported. This ensures you can use the EUI framework's aesthetic while accessing the dynamic theming capabilities.
Here's a snippet to set up a dark-themed application:
1import React from 'react'; 2import { EuiProvider, EuiText } from '@elastic/eui'; 3import '@elastic/eui/dist/eui_theme_dark.css'; 4 5const MyApp = () => ( 6 <EuiProvider colorMode="dark"> 7 <EuiText> 8 <p>Hello World!</p> 9 </EuiText> 10 </EuiProvider> 11); 12 13export default MyApp; 14
The EUI framework distributes UI React components that are versatile and typed for TypeScript users. These typed UI React components ensure that developers can confidently build interfaces with the assurance of type safety.
For instance, when you're building web layouts, you can use the EuiFlexGroup and EuiFlexItem components to create responsive and composable configurations:
1import React from 'react'; 2import { EuiFlexGroup, EuiFlexItem, EuiCard } from '@elastic/eui'; 3 4const Layout = () => ( 5 <EuiFlexGroup gutterSize="l"> 6 <EuiFlexItem> 7 <EuiCard 8 icon={<EuiIcon size="xxl" type="logoElasticStack" />} 9 title="Elastic Stack" 10 description="Start your journey with Elastic UI" 11 /> 12 </EuiFlexItem> 13 {/* Add more EuiFlexItems as needed */} 14 </EuiFlexGroup> 15); 16 17export default Layout; 18
One of the core strengths of the EUI framework is its comprehensive collection of UI React components. These components are meticulously documented and tested, ensuring that developers have access to reliable and scalable components for building web layouts. The framework's React components and static assets are designed to work harmoniously, providing a seamless development experience.
For example, when you need to create a table with child components.
1import React from 'react'; 2import { EuiBasicTable } from '@elastic/eui'; 3 4const MyTable = ({ items }) => { 5 const columns = [ 6 { 7 field: 'firstName', 8 name: 'First Name', 9 }, 10 // Add more column definitions here 11 ]; 12 13 return <EuiBasicTable items={items} columns={columns} />; 14}; 15 16export default MyTable;
The Elastic UI framework offers a robust set of static assets and theming options. Using the useEuiTheme hook allows you to access theme tokens to style your UI components. This allows for a design library that is both flexible and consistent with the EUI framework aesthetic.
Elastic UI is committed to accessibility, ensuring that most assistive technology can navigate and interact with the UI components seamlessly. The framework includes an SVG icon library that is accessible and easy to use within your React components.
The Elastic UI framework EUI is a treasure trove for developers looking to create user interfaces that are not only visually appealing but also highly functional. With a design library that includes reusable UI components, static assets, and a comprehensive SVG icon library, Elastic UI empowers developers to build internal products quickly.
Elastic UI allows for extensive customization of existing component functionality. You can use the EuiThemeProvider to override global style tokens, ensuring that your application aligns with your brand's visual identity while still leveraging the power of Elastic UI.
The Elastic UI framework is a testament to Elastic's commitment to providing developers with tools that assist in quickly building user interfaces that are both beautiful and accessible. With its composable and configurable components, Elastic UI enables developers to create repeatable content that adheres to the design principles of the Elastic UI framework. Whether you are working on internal products or aiming to maintain a consistent user experience across various projects, Elastic UI is ready to lend a hand.
