Install

You can install the react-stack-grid from npm.

$ npm install react-stack-grid

Quick Example

Following code is simplest usage.

import React, { Component } from "react"; import StackGrid from "react-stack-grid";  class MyComponent extends Component {   render() {     return (       <StackGrid         columnWidth={150}       >         <div key="key1">Item 1</div>         <div key="key2">Item 2</div>         <div key="key3">Item 3</div>       </StackGrid>     );   } }

width of parent is managed by react-sizeme.

Props

You can set the following properties.

Property	Type	Default	Description
`className`	`PropTypes.string`	`undefined`	Specify `className` of component.
`style`	`PropTypes.object`	`{}`	Original style of component. Following styles are ignored. (`position`, `height`, `transition`)
`gridRef`	`PropTypes.func`	`null`	Reference the instance of StackGrid. Unlike ordinary `ref`, it accepts only functions.
`component`	`PropTypes.string`	`"div"`	See ReactTransitionGroup
`itemComponent`	`PropTypes.string`	`"span"`	Specify the component of the grid item.
`columnWidth`	`PropTypes.oneOfType([PropTypes.number, PropTypes.string])`	`150`	Specify column width as an number(`px`), or percentage string. (Example `"33.33%"`)
`gutterWidth`	`PropTypes.number`	`5`	Specify gutter width as an number.
`gutterHeight`	`PropTypes.number`	`5`	Specify gutter height as an number.
`duration`	`PropTypes.number`	`480`	Specify duration of animation in ms.
`easing`	`PropTypes.string`	`easings.quartOut`	Specify a css valid transition-timing-function string. It can be easily specification by using `easings`.
`appearDelay`	`PropTypes.number`	`30`	Specify delay of the initial animation in ms.
`appear`	`PropTypes.func`	`fadeUp.appear`	See Animations section.
`appeared`	`PropTypes.func`	`fadeUp.appear`	...
`enter`	`PropTypes.func`	`fadeUp.appear`	...
`entered`	`PropTypes.func`	`fadeUp.appear`	...
`leaved`	`PropTypes.func`	`fadeUp.appear`	...
`units`	`PropTypes.func`	`{ length: "px", angle: "deg" }`	...
`monitorImagesLoaded`	`PropTypes.bool`	`false`	If set to `true`, images reading is monitored. use imagesloaded.
`vendorPrefix`	`PropTypes.bool`	`false`	If set to `true`, add a vendor prefix to styles add dynamically.
`userAgent`	`PropTypes.string`	`undefined`	Specify userAgent for determinig the vendor prefix. See inline-style-prefixer.
`enableSSR`	`PropTypes.bool`	`false`	Render component on the server side. More info.
`onLayout`	`PropTypes.func`	`null`	It is called at the timing when the layout is confirmed, or at the updated timing. (Called only by client.)
`horizontal`	`PropTypes.bool`	`false`	The transposed (horizontal) order of drawing elements. Retains the original order of the items.
`rtl`	`PropTypes.bool`	`false`	When true, items are placed right-to-left instead of the default left-to-right. Useful for RTL languages such as Arabic and Hebrew.

Instance API

updateLayout(): void

Update the current layout.

Animations

The following function must return styles related to animation.
See ReactTransitionGroup for details.

appear
appeared
enter
entered
leaved

You can use extended syntax for transform's style. For example properties like translateX and scale.
See easy-css-transform-builder.

Each function is given the following arguments.

rect: { top: number; left: number; width: number; height: number; }
containerSize: { width: number; height: number; }
index: number

It is easiest to use them because you have several presets.

fade
fadeDown
fadeUp
scaleDown
scaleUp
flip
helix

It's an actual use example.

import StackGrid, { transitions } from "react-stack-grid";  const { scaleDown } = transitions;  class MyComponent extends Component {   render() {     return (       <StackGrid         ...         appear={scaleDown.appear}         appeared={scaleDown.appeared}         enter={scaleDown.enter}         entered={scaleDown.entered}         leaved={scaleDown.leaved}       >         ...       </StackGrid>     );   } }

Please try actual demonstration in live demo.

Tips

Performance when using images

When true is specified for monitorImagesLoaded, reloading occurs when the image loading is completed.
If you know the size in advance, specify monitorImagesLoaded as false.

When animation is unnecessary

By default animation is enabled.
If it's not necessary, specify 0 for duration property.

<StackGrid   ...   duration={0} >   ... </StackGrid/>

How to manually update layout ?

If the size of an item is changed by an action such as a click event, there are cases where you want to update the layout manually.
You can manually update the layout by referring to the StackGrid instance with gridRef and executing theupdateLayout() method.

class MyComponent extends React.Component {    // When the size of the item is changed...   something = () => {     this.grid.updateLayout();   };    render() {     return (       <StackGrid         gridRef={grid => this.grid = grid}       >         {/* items ... */}       </StackGrid>     );   } }

Responsive layout

You can get width using react-sizeme and change columnWidth according to width.
This is a solution, but we can respond in other ways!

import React, { Component } from 'react'; import sizeMe from 'react-sizeme'; import StackGrid from 'react-stack-grid';  class YourComponent extends Component {   render() {     const {        size: {          width       }      } = this.props;      return (       <StackGrid         // more...         columnWidth={width <= 768 ? '100%' : '33.33%'}       >         // Grid items...       </StackGrid>     );   } }  export default sizeMe()(YourComponent);
