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 🙏

Vue 3 integration for layout-adaptor — composable hooks and components

Readme

@tinyforged/layout-adaptor-vue

@tinyforged/layout-adaptor 的 Vue 3 集成包,提供 Composable Hook 和 Provider 组件。

内置 @tinyforged/layout-adaptor 作为依赖,无需单独安装。

安装

pnpm add @tinyforged/layout-adaptor-vue

useLayoutAdaptor

Composable Hook,自动管理适配器的挂载与卸载生命周期。支持传入 Vue ref 作为目标元素。

基本用法

<template>
  <div ref="containerRef">
    <h1>数据大屏</h1>
  </div>
</template>

<script setup lang="ts">
import { ref } from "vue";
import { useLayoutAdaptor } from "@tinyforged/layout-adaptor-vue";

const containerRef = ref<HTMLElement>();

const { scale, started } = useLayoutAdaptor({
  target: containerRef,
  designWidth: 1920,
  designHeight: 1080,
  fitMode: "contain",
  resize: true,
});
</script>

也支持 CSS 选择器字符串:

<script setup lang="ts">
import { useLayoutAdaptor } from "@tinyforged/layout-adaptor-vue";

const { scale } = useLayoutAdaptor({
  target: "#app",
  designWidth: 1920,
  designHeight: 1080,
});
</script>

动态更新配置

<script setup lang="ts">
const { update, disable, enable, setAdaptMode } = useLayoutAdaptor({
  target: "#app",
  designWidth: 1920,
  designHeight: 1080,
});

// 运行时更新设计稿尺寸
function switchTo720p() {
  update({ designWidth: 1280, designHeight: 720 });
}

// 切换适配策略
setAdaptMode("rem");

// 临时禁用/启用
disable();
enable();
</script>

监听事件

<script setup lang="ts">
const { on, off, scale } = useLayoutAdaptor({
  target: "#app",
  designWidth: 1920,
  designHeight: 1080,
});

function handleScale(s: number) {
  console.log("当前缩放:", s);
}

on("scaleChange", handleScale);
// off("scaleChange", handleScale);
</script>

响应式配置

支持传入 ref 包裹的配置对象,实现响应式更新:

<script setup lang="ts">
import { ref } from "vue";
import { useLayoutAdaptor } from "@tinyforged/layout-adaptor-vue";

const options = ref({
  target: "#app",
  designWidth: 1920,
  designHeight: 1080,
  fitMode: "contain" as const,
});

const { scale } = useLayoutAdaptor(options);
</script>

返回值

| 属性 | 类型 | 说明 | | ---------------------- | ------------------------------- | -------------- | | scale | Ref<number> | 当前缩放比例 | | started | Ref<boolean> | 是否已启动 | | adaptor | Ref<LayoutAdaptor \| null> | 适配器实例 | | adaptMode | Ref<AdaptMode> | 当前适配策略 | | direction | Ref<Direction> | 当前缩放方向 | | activeBreakpoint | Ref<BreakpointConfig \| null> | 当前激活的断点 | | disabled | Ref<boolean> | 是否禁用 | | update(options) | Function | 更新配置 | | setAdaptMode(mode) | Function | 切换适配策略 | | setDirection(dir) | Function | 切换缩放方向 | | enable() | Function | 启用 | | disable() | Function | 禁用 | | on(event, listener) | Function | 监听事件 | | off(event, listener) | Function | 取消监听 |

LayoutAdaptorProvider

Provider 组件,通过 Props 声明式配置,子组件通过 useLayoutAdaptorInject 共享适配器状态。

Provider 基本用法

<script setup>
import { LayoutAdaptorProvider } from "@tinyforged/layout-adaptor-vue";
</script>

<template>
  <LayoutAdaptorProvider
    design-width="1920"
    design-height="1080"
    target="#app"
    fit-mode="contain"
    :resize="true"
  >
    <YourContent />
  </LayoutAdaptorProvider>
</template>

也支持通过 options prop 传入完整配置对象:

<script setup>
const adaptorOptions = {
  target: "#app",
  designWidth: 1920,
  designHeight: 1080,
  fitMode: "contain",
  resize: true,
};
</script>

<template>
  <LayoutAdaptorProvider :options="adaptorOptions">
    <YourContent />
  </LayoutAdaptorProvider>
</template>

Provider 事件监听

<script setup>
import { LayoutAdaptorProvider } from "@tinyforged/layout-adaptor-vue";

function onScale(scale) {
  console.log("缩放变化:", scale);
}
</script>

<template>
  <LayoutAdaptorProvider
    design-width="1920"
    design-height="1080"
    target="#app"
    @scale-change="onScale"
    @ready="() => console.log('就绪')"
    @error="(e) => console.error(e)"
  >
    <YourContent />
  </LayoutAdaptorProvider>
</template>

Props

所有 core 包的 LayoutAdaptorOptions 均可作为 Props 传入(使用 kebab-case):

| Prop | 类型 | 默认值 | 说明 | | ---------------- | -------------------------------- | --------- | ------------------------------------ | | options | LayoutAdaptorOptions | {} | 完整配置对象(优先级低于单独 Props) | | target | string | #app | 目标元素选择器 | | design-width | number | 1920 | 设计稿宽度 | | design-height | number | 1080 | 设计稿高度 | | fit-mode | FitMode | contain | 适配方式 | | adapt-mode | AdaptMode | scale | 适配策略 | | align-x | AlignX | left | 水平对齐 | | align-y | AlignY | top | 垂直对齐 | | resize | boolean | true | 监听窗口 resize | | resize-delay | number | 0 | resize 防抖(ms) | | transition | number | 0 | 过渡动画(ms) | | overflow | OverflowMode | hidden | 溢出处理 | | min-scale | number | - | 最小缩放比例 | | max-scale | number | - | 最大缩放比例 | | direction | Direction | both | 缩放方向 | | keep-dpr | boolean | false | 保持设备像素比 | | root-font-size | number | 16 | rem 基准字号 | | breakpoints | BreakpointConfig[] | - | 响应式断点 | | custom-fit | CustomFitFn | - | 自定义适配函数 | | debug | boolean \| DebugOverlayOptions | false | 调试模式 | | disabled | boolean | false | 是否禁用 | | class-name | string | - | 附加 CSS 类名 |

Events

scale-change / resize / render / start / stop / ready / error / adapt-mode-change / breakpoint-change / direction-change / before-render

useLayoutAdaptorInject

LayoutAdaptorProvider 内部的子组件中使用,获取共享的适配器状态。

<script setup lang="ts">
import { useLayoutAdaptorInject } from "@tinyforged/layout-adaptor-vue";

const { scale, adaptMode, setAdaptMode, disable, on } =
  useLayoutAdaptorInject();

on("breakpointChange", (bp) => {
  console.log("断点切换:", bp);
});
</script>

Inject 返回值

| 属性 | 类型 | 说明 | | ---------------------- | ------------------------------- | ------------ | | adaptor | Ref<LayoutAdaptor \| null> | 适配器实例 | | scale | Ref<number> | 当前缩放比例 | | adaptMode | Ref<AdaptMode> | 当前适配策略 | | direction | Ref<Direction> | 当前缩放方向 | | activeBreakpoint | Ref<BreakpointConfig \| null> | 当前断点 | | disabled | Ref<boolean> | 是否禁用 | | setAdaptMode(mode) | Function | 切换适配策略 | | setDirection(dir) | Function | 切换缩放方向 | | enable() | Function | 启用 | | disable() | Function | 禁用 | | on(event, listener) | Function | 监听事件 | | off(event, listener) | Function | 取消监听 |
