logo Nice React Layout

A set of React components to create complex flexbox-based layouts without knowing what flexbox is. https://ekros.github.io/nice-react-layout/

Installation

yarn add nice-react-layout

Motivation

The aim of this project is to have a reduced set of components to create flexbox-based layouts abstracting the knowledge needed to understand how flexbox works. This library is very useful for web apps with lots of panels.

Features

  • Easy to learn: Just combine layouts and panels.
  • Create collapsible sidebars with ease.
  • Automagically colorize panels with random colors to speed-up prototyping.
  • Resizable panels. Just add separators to your layouts.

Simple example

Basic Usage

Components can be imported using ES6 modules syntax:

  import { HorizontalLayout,
           VerticalLayout,
           Panel,
           Separator,
           Spacer,
           View } from "nice-react-layout";

Creating a simple layout is as easy as this:

  <HorizontalLayout mockup>
    <Panel />
    <Panel />
  </HorizontalLayout>

It renders an horizontal layout with two panels of the same size (they have proportion=1 by default). Thanks to the 'mockup' prop it paints every panel with a random color, easing the layout prototyping process. Layouts get all the available space by default (in the parent element). If you want your layout to fill the viewport you can use the component. Like this:

  <View>
    <HorizontalLayout mockup>
      <Panel />
      <Panel />
    </HorizontalLayout>
  </View>

In both horizontal and vertical layouts add the prop 'proportion' with the proportional part it takes from the available space. This example creates a typical sidebar + content layout:
  <HorizontalLayout mockup>
    <Panel proportion={1} />
    <Panel proportion={4} />
  </HorizontalLayout>

Do you want to add a separator between both panels? Use the Separator component:
  <HorizontalLayout mockup>
    <Panel proportion={1} />
    <Separator />
    <Panel proportion={4} />
  </HorizontalLayout>

You can nest layouts. Let's add a vertical layout, with its own Separator, inside the right panel:
  <HorizontalLayout mockup>
    <Panel proportion={1} />
    <Separator />
    <Panel proportion={4}>
      <VerticalLayout mockup>
        <Panel />
        <Separator />
        <Panel />
      </VerticalLayout>
    </Panel>
  </HorizontalLayout>

For a complete example with every feature, see the src/demo/App.js file. Or just run yarn start.

Components

View

The top-level component. It gets all the available viewport space. Use it if you want your layout to fill the viewport or pass width / height props.

Props
Prop Description
width view width (100vw by default)
height view height (100vh by default)

HorizontalLayout

It creates an horizontal layout. This is shorthand component for:

  <Layout orientation="horizontal" />

VerticalLayout

It creates vertical layout layout. This is a shorthand component for:

  <Layout orientation="vertical" />

Layout

Creates a layout.

Props
Prop Description
className Top-level element class name
collapseSize Collapsible panels size when collapsed
customCss Custom layout CSS object
mockup Render in mockup mode
onResize Returns (layout, collapsedPanels) on resize
orientation 'vertical' or 'horizontal'
reverse Render layout in reverse order

Panel

Here is where your content goes. If you are familiar with flexbox, this is like a "flex item" with a flex value of 1 by default. If not, don't worry, you don't need to know that :)

Props
Prop Description
centered Center panel content
className Top-level element class name
collapsible The panel can be collapsed
collapsed Is the panel collapsed?
collapseButtonClass Adds a class to the collapse button
collapseButtonContent A String or element
collapseButtonCollapsedContent A String or element
collapseButtonStyle Inject inline CSS to the collapse button
collapsePanel Called when collapse button is clicked
collapseSwitch Custom collapse element (renders button if not provided)
columns Number of columns (uses CSS multiple columns)
customCss Custom panel CSS object (injects it as an inline style)
minHeight Minimum panel height
minWidth Minimum panel width
mockup Render in mockup mode
orientation 'vertical' or 'horizontal'
proportion Proportion it uses from the available space (default = 1)
reverse Render layout in reverse order
showSize Show panel size while dragging adjacent separators
sidebar Don't do much by it self. It is a requirement for sidebar props like 'collapsible'

Separator

It separates panels and allows them to be resized. This is optional.

Props
Prop Description
customCss Custom separator CSS object (injects it as an inline style)
defaultDblClickPos Position where the separator goes when double-clicked
disabled Is disabled?
onSeparatorDoubleClick Action called when the separator is double-clicked
onSeparatorMouseDown Action called when the mouse is over the separator

Spacer

It renders a blank space. Useful when you need to leave spaces between panels.

Props
Prop Description
size Separator size in pixels
