# react-window
> 高效渲染大数据列表和表格的react组件
React window基于仅渲染大数据中的部分数据(刚好填充满视窗)的方法,来帮助我们解决一些常见的的性能瓶颈问题:
1. 它减少了初始渲染和处理更新时的耗时
2. 减少内存占用,从而避免大量DOM节点引起的内存泄漏.[![NPM registry](https://img.shields.io/npm/v/react-window.svg?style=for-the-badge)](https://yarnpkg.com/en/package/react-window) [![Travis](https://img.shields.io/badge/ci-travis-green.svg?style=for-the-badge)](https://travis-ci.org/bvaughn/react-window) [![NPM license](https://img.shields.io/badge/license-mit-red.svg?style=for-the-badge)](LICENSE.md)
## 安装

## 相关库信息
* [`react-virtualized-auto-sizer`](https://npmjs.com/package/react-virtualized-auto-sizer): 高阶组件:动态适配可用的空间,并且支持传入width和height值到子组件
* [`react-window-infinite-loader`](https://npmjs.com/package/react-window-infinite-loader): 帮助大数据分组和根据视图滚动实时加载。也可以被用于无限加载的列表中(e.g. Facebook or Twitter).
* [`react-vtree`](https://www.npmjs.com/package/react-vtree):
一个轻量灵活的解决大数据目录结构渲染的库(比如文件系统目录结构)## 常见问题
### `react-window`和`react-virtualized`有何不同?
我几年前写了`react-virtualized`。当时,我对React和window的概念了解很浅。因此,我封装了一些API,但是后来我后悔了。原因之一是其中添加了太多没必要的特性和组件 。一旦你向开源项目添加些东西,删除它对用户是件很痛苦的事情`react-window` 基于 `react-virtualized`完全重写. 我不用尝试解决那么多遗留问题或者支持那么多用例. 相反我聚焦在让包体积更小,运行效率更高的问题上来。我也花了很多心思在设计API和文档上来,让其对初学者更友好(当然window仍然是种高级用例)。
如果你的项目需要`react-window`提供的功能,我强烈建议用它替代`react-virtualized`. 然后如果需要一些仅`react-virtualized`提供的特性, 你有两个选择:
1. 继续使用 `react-virtualized`. (它仍广泛的应用于各种成功案例)
2. 创建一个封装了`react-window`基类的组件并且添加你需要的功能。你也可以发布这个组件到npm上 🙂PS: 添加一个`react-virtualized`列表到一个CRA(create-react-app)项目中, gzip构建包增加了33.5kb. 同样的的添加一个`react-window`列表到CRA项目中,gzip构建包仅增加了2kb
### 一个列表或者网格结构可以100%填充页面的宽高么?
可以. 我推荐使用 [`react-virtualized-auto-sizer` 库](https://npmjs.com/package/react-virtualized-auto-sizer):
这是一个 [Sandbox上的例子](https://codesandbox.io/s/3vnx878jk5).
### 页面滚动的时候为什么会出现空白?
如果你的页面看起来像这样...
...那么你有可能是忘记`style`参数了! react-window这样的库基于绝对定位来展示 (通过一个内联样式), 所以不要忘记绑定到你渲染的DOM元素上!
### 列表支持懒加载数据么?
支持,推荐使用 [`react-window-infinite-loader` package](https://npmjs.com/package/react-window-infinite-loader):
这是一个 [Sandbox上的例子](https://codesandbox.io/s/5wqo7z2np4).
### 可以绑定自定义属性和事件处理么?
可以, 使用 `outerElementType` 属性.
这是一个 [Sandbox上的例子](https://codesandbox.io/s/4zqx79nww0).
### 列表收尾可以添加padding么?
可以, 虽然需要一点点内联样式.
这是一个 [Sandbox上的例子](https://codesandbox.io/s/react-window-list-padding-dg0pq).
### 列表的元素间可以添加gutter或者padding么?
可以, 虽然需要一点点内联样式.
这是一个 [Sandbox上的例子](https://codesandbox.io/s/2w8wmlm89p).
### 支持内部元素sticky处理么?
支持,不过需要一点代码修改. 这是一个 [Sandbox上的例子](https://codesandbox.io/s/0mk3qwpl4l).
