A component that can arrange items according to the type of grids.

Demo /  API

MasonryGrid	JustifiedGrid	FrameGrid	PackingGrid

• MasonryGrid: The MasonryGrid is a grid that stacks items with the same width as a stack of bricks. Adjust the width of all images to the same size, find the lowest height column, and insert a new item.
• JustifiedGrid: 'justified' is a printing term with the meaning that 'it fits in one row wide'. The JustifiedGrid is a grid that the item is filled up on the basis of a line given a size.
• FrameGrid: 'Frame' is a printing term with the meaning that 'it fits in one row wide'. The FrameGrid is a grid that the item is filled up on the basis of a line given a size.
• PackingGrid: The PackingGrid is a grid that shows the important items bigger without sacrificing the weight of the items. Rows and columns are separated so that items are dynamically placed within the horizontal and vertical space rather than arranged in an orderly fashion.

Download dist files from repo directly or install it via npm.

$ npm install @egjs/grid

<script src="//naver.github.io/egjs-grid/release/latest/dist/grid.min.js"></script>

import { MasonryGrid, JustifiedGrid, FrameGrid, PackingGrid } from "@egjs/grid";


// Grid.MasonryGrid
const grid = new MasonryGrid(container, {
  gap: 5,
});

grid.renderItems();

• When the loading="lazy" or data-grid-lazy="true"(external lazy loading) attribute is used, Rendering of the items occurs immediately. When items are loaded, they are rendered sequentially.

<img src="..." />
<img src="..." />
<img src="..." loading="lazy" />
<img data-grid-lazy="true" />

• If you use data-grid-width and data-grid-height attributes, the size of self, child image, and video elements is automatically adjusted until loading is complete.

<div data-grid-width="100" data-grid-height="100">
   <img src="..." />
   <img src="..." />
   <img src="..." />
</div>

• If you use data-grid-skip="true" attribute, you can omit it even if there are images in itself and child image, and video elements.

<div data-grid-skip="true">
   <img src="..." />
   <img src="..." />
   <img src="..." />
</div>

Grid calculates the size of container and children by window resizing event. However, even if the size of the window does not change, the size of the event container and children can change. Most of the first rendering issues are also like this.

In this case, I recommend ResizeObserver for you.

Provides useResizeObserver option to detect size change of container and observeChildren option to detect size change of children.

import { MasonryGrid, JustifiedGrid, FrameGrid, PackingGrid } from "@egjs/grid";


// Grid.MasonryGrid
const grid = new MasonryGrid(container, {
  gap: 5,
  useResizeObserver: true,
  observeChildren: true,
});

grid.renderItems();

If you use the isEqualSize option, all items are considered to be the same size. Each resize only calculates the size of one item. Add data-grid-not-equal-size="true" attribute if there is an exceptional item whose size needs to be calculated while using isEqualSize.

<div class="item item1"></div>
<div class="item item1"></div>
<div class="item item1"></div>
<!--item2 is a different size than item1.-->
<div class="item item2" data-grid-not-equal-size="true"></div>

isEqualSize assumes all items are equal. But if there are more than two size-groups, use data-grid-size-group.

<!--item1 has the same size.-->
<div class="item item1" data-grid-size-group="1"></div>
<div class="item item1" data-grid-size-group="1"></div>
<!--item2 has the same size.-->
<div class="item item2" data-grid-size-group="2"></div>
<div class="item item2" data-grid-size-group="2"></div>

If all items do not have a constant size, use the isConstantSize option. Resizing doesn't calculate the item's size. If you want to recalculate, use .updateItems(items, { useOrgResize: true }) method or .renderItems({ useOrgResize: true }) method.

For anyone interested to develop egjs-grid, follow the instructions below.

Clone the egjs-grid repository and install the dependency modules.

# Clone the repository.
$ git clone https://github.com/naver/egjs-grid.git

# Install the dependency modules.
$ npm install

Run storybook for development.

Open http://localhost:6006 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

Use npm script to build Grid

$ npm run build

Two folders will be created after complete build is completed.

• dist folder: Includes the grid.js and grid.min.js files.
• doc folder: Includes API documentation. The home page for the documentation is doc/index.html.

To keep the same code style, we adopted ESLint to maintain our code quality. The rules are modified version based on Airbnb JavaScript Style Guide. Setup your editor for check or run below command for linting.

$ npm run lint

Once you created a branch and done with development, you must perform a test running with npm test command before your push the code to a remote repository.

$ npm run test

Running npm test command will start Mocha tests via Karma-runner.

If you find a bug, please report to us opening a new Issues on GitHub.
