A module used to arrange elements including content infinitely according to grid type. With this module, you can implement various grids composed of different card elements whose sizes vary. It guarantees performance by maintaining the number of DOMs the module is handling under any circumstance

* [InfiniteGrid 4 Release!!](https://medium.com/naver-fe-platform/infinitegrid-4-release-f4e2d05b0292)
## ⚙️ Installation
#### npm
```bash
$ npm install --save @egjs/infinitegrid
```
#### CDN
- jsDelivr: https://cdn.jsdelivr.net/npm/@egjs/infinitegrid/dist/
- unpkg: https://unpkg.com/@egjs/infinitegrid/dist/
- cdnjs: https://cdnjs.com/libraries/egjs-infinitegrid
## 🏃 Quick Start
#### HTML
```html
```
#### ES Modules
```ts
import { MasonryInfiniteGrid } from "@egjs/infinitegrid";
const ig = new MasonryInfiniteGrid(".container", { gap: 5 });
```
#### With CDN
```html
```
```js
var ig = new InfiniteGrid.MasonryInfiniteGrid(".container", { gap: 5 });
```
```js
import { MasonryInfiniteGrid } from "@egjs/infinitegrid";
function getItems(nextGroupKey, count) {
const nextItems = [];
for (let i = 0; i < count; ++i) {
const num = nextGroupKey * count + i;
nextItems.push(``);
}
return nextItems;
}
const ig = new MasonryInfiniteGrid(".container", {
gap: 5,
});
ig.on("requestAppend", (e) => {
const nextGroupKey = (+e.groupKey || 0) + 1;
ig.append(getItems(nextGroupKey, 10), nextGroupKey);
});
ig.renderItems();
```
### Use Faster & Lazy Rendering
* 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.
```html
![]()
```
* 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.
```html
```
* 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.
```html
```
### Detect resize of Container & Children
InfiniteGrid 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](https://developer.mozilla.org/en-US/docs/Web/API/ResizeObserver) for you.
Provides `useResizeObserver` option to detect size change of container and `observeChildren` option to detect size change of children.
```js
import { MasonryInfiniteGrid, JustifiedInfiniteGrid, FrameInfiniteGrid, PackingInfiniteGrid } from "@egjs/infinitegrid";
// InfiniteGrid.MasonryInfiniteGrid
const grid = new MasonryInfiniteGrid(container, {
gap: 5,
useResizeObserver: true,
observeChildren: true,
});
grid.renderItems();
```
## Pre-guess size for performance or invisible items.
### What if all items were the same size?
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.
```html
```
### What if a size group exists?
`isEqualSize` assumes all items are equal. But if there are more than two size-groups, use `data-grid-size-group`.
```html
```
### What if all items don't change size?
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.
