Atomic Layout is a spatial distribution library for React. It usesCSS Grid to define layout areas and render them as React components. This pattern encourages separation of elements and spacing, preventing contextual implementations and boosting maintenance of layouts.

importReactfrom'react'import{Composition}from'atomic-layout'// Define layout areas: visual representation// of what composes a layout, detached from// what components are actually rendered.constareasMobile=`  thumbnail  header  footer`// Declare responsive changes of your areas.// Operate in two dimensions, remove areas// or introduce new ones.constareasTablet=`  thumbnail header  thumbnail footer`constCard=({ title, imageUrl, actions})=>(<Compositionareas={areasMobile}areasMd={areasTablet}gap={20}>{/* Get React components based on provided areas */}{({ Thumbnail, Header, Footer})=>(<React.Fragment><Thumbnail>{/* Render anything, including another Composition */}<imgsrc={imageUrl}alt={title}/></Thumbnail>{/* Preserve semantics with polymorphic prop */}<Headeras="h3">{title}</Header>{/* Responsive props: just suffix with a breakpoint name */}<Footerpadding={10}paddingMd={20}>{actions}</Footer></React.Fragment>)}</Composition>)exportdefaultCard

Atomic Layout is responsive-first. It usesBootstrap 4 breakpoints by default, which you can alwayscustomize for your needs.

Modern layout development is about modularity and composition. Following the best practices ofAtomic design, we strive toward independent UI units that gradually compose into more meaningful pieces. While the attention paid to units implementation is thorough, we often overlook how to achieve layout composition that scales. It's as if we forget thatspacing defines composition.

When it comes to distributing the spacing things get more difficult. First of all, true contextless spacing is hard. To make things worse, all present solutions couple spacing with UI elements, inevitably making small reusable piecescontextful and, thus, hard to maintain.

Atomic Layout helps you to compose your elements by introducing a dedicated spacing layer calledComposition. It encourages you to separate concerns between UI elements' visual appearance and spacing between them. With the first-class responsive support at your disposal you can build gorgeous responsive permutations of your elements without leaving the dedicated spacing layer, keeping UI elements contextless and predictable. Embrace the era of a true layout composition!

Atomic Layout has multiple implementations depending on the styling solution:

Package name	Latest version	Styling library
atomic-layout		styled-components
@atomic-layout/emotion		@emotion/styled

See theOfficial documentation.

Here are some shortcuts for quick access:

• Motivation
• Getting started
• Responsive props
• Recipes

Although the examples below useatomic-layout package, they are fully compatible with other styling implementations of the library (i.e.@atomic-layout/emotion).

Basic composition Combine two UI elements into a single one using Composition.

Responsive props Change a prop's value depending on a breakpoint.

Nested composition Any element can be a compositionand a composite at the same time.

Conditional rendering Render or display elements conditionally based on breakpoints.

Custom configuration Configure a default measurement unit, custom breakpoints, and responsive behaviors.

Shorthand media query Use a shorthandquery function to declare inline media queries in CSS.

Atomic Layout's browser support is made by the browser support of underlying technologies the library uses. Pay attention if your project can support CSS Grid to be sure you can use Atomic Layout.

See theSupport table for CSS Grid. For Internet Explorer support please readthis issue.
