Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

安装

# npm
npm install react-flex-kit

# yarn
yarn add react-flex-kit

# pnpm
pnpm add react-flex-kit

# bun
bun add react-flex-kit

基本使用

Web

import { Row, Col, Flex } from 'react-flex-kit';

function App() {
  return (
    <Col space={4} fullWidth>
      <Row space={2} justify="between">
        <span>Left</span>
        <span>Right</span>
      </Row>
      <Row space={2}>
        <button>Button 1</button>
        <button>Button 2</button>
        <button>Button 3</button>
      </Row>
    </Col>
  );
}

React Native

import { Row, Col, Flex } from 'react-flex-kit/native';

function App() {
  return (
    <Col space={4} fullWidth>
      <Row space={2} justify="between">
        <Text>Left</Text>
        <Text>Right</Text>
      </Row>
      <Row space={2}>
        <Button title="Button 1" />
        <Button title="Button 2" />
      </Row>
    </Col>
  );
}

组件

Row

水平方向的 Flex 容器。

<Row space={4} align="center" justify="between">
  {children}
</Row>

Col

垂直方向的 Flex 容器。

<Col space={4} align="center" justify="start">
  {children}
</Col>

Flex

通用 Flex 容器,可指定方向。

<Flex direction="row" space={4}>
  {children}
</Flex>

Props

| 属性 | 类型 | 默认值 | 说明 | | ------------ | ---------------------------- | ---------- | ------------------- | | children | ReactNode | - | 子元素 | | reverse | boolean | false | 反转子元素顺序 | | fullWidth | boolean | false | 宽度 100% | | fullHeight | boolean | false | 高度 100% | | align | FlexAlign | "center" | 交叉轴对齐 | | justify | FlexJustify | "start" | 主轴对齐 | | space | number \| string | 2 | 子元素间距 | | className | string | - | CSS 类名 (仅 Web) | | style | CSSProperties \| ViewStyle | - | 内联样式 | | direction | FlexDirection | "row" | 方向 (仅 Flex 组件) | | ref | Ref | - | 元素引用 |

FlexAlign

type FlexAlign = "start" | "center" | "end" | "stretch" | "baseline";

FlexJustify

type FlexJustify = "start" | "center" | "end" | "between" | "around" | "evenly";

FlexDirection

type FlexDirection = "row" | "row-reverse" | "column" | "column-reverse";

间距系统

space 属性遵循 Tailwind CSS 的间距系统:

| space | Web | React Native | | -------- | ------- | ------------ | | 1 | 0.25rem | 4px | | 2 | 0.5rem | 8px | | 4 | 1rem | 16px | | 8 | 2rem | 32px | | "20px" | 20px | - |

自定义配置

使用 createFlexComponents 创建自定义配置的组件:

Web

import { createFlexComponents } from 'react-flex-kit';

export const { Row, Col, Flex } = createFlexComponents({
  // 自定义 gap 计算函数
  gapCalculator: (space) => `${space * 4}px`,
  // 默认间距
  defaultSpace: 4,
  // 默认对齐
  defaultAlign: "start",
  // 默认主轴对齐
  defaultJustify: "start",
});

React Native (使用 nativewind-scale)

import { scale } from '@flickering/nativewind-scale';
import { createFlexComponents } from 'react-flex-kit/native';

export const { Row, Col, Flex } = createFlexComponents({
  // 使用响应式缩放
  gapCalculator: (space) => scale(space),
  defaultSpace: 8,
});

样式优先级

组件 props > 内联 style > className (Tailwind)

// fullWidth 会覆盖 style 的 width
<Row fullWidth style={{ width: "50%" }}>
  {/* width: 100% (fullWidth 优先) */}
</Row>

// style 中不冲突的属性会保留
<Row fullWidth style={{ padding: "10px" }}>
  {/* width: 100%, padding: 10px */}
</Row>

// 组件 props 生成的内联样式会覆盖 Tailwind 类
<Row className="gap-2" space={4}>
  {/* gap: 1rem (space={4}) 覆盖 gap-2 */}
</Row>

HTML 属性透传

组件支持所有原生 HTML/View 属性:

// Web
<Row
  data-testid="my-row"
  aria-label="Row container"
  onClick={() => console.log('clicked')}
>
  {children}
</Row>

// React Native
<Row
  testID="my-row"
  accessibilityLabel="Row container"
  onLayout={(e) => console.log(e)}
>
  {children}
</Row>

TypeScript

完整的类型支持:

import type {
  FlexLayoutProps,
  FlexProps,
  FlexAlign,
  FlexJustify,
  FlexDirection,
  FlexConfig,
} from 'react-flex-kit';

// React Native
import type {
  NativeFlexLayoutProps,
  NativeFlexProps,
} from 'react-flex-kit/native';

兼容性

  • React 17+
  • React Native 0.60+
  • TypeScript 4.7+
