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 🙏

cover

1.X版本文档请查看:V1.x文档

如何从1.x升级到2.x

  1. 只需将1.x中自定义的config和options配置项合并即可,如无自定义配置项 那么可直接升级,参考下方配置
  2. 2.x版本调整了themes初始化配置项,将Map对象改为普通对象,初始化速度更快,自定义主题更便捷

// -- 1.x版本 --
const config={
  enabled: true,
}
const options={
  ruleSize: 20,
}
const ruler = new Ruler(app,config,options)

// -- 2.x版本,只需将config和options合并即可 --
const config={
  enabled: true,
  ruleSize: 20,
}
const ruler = new Ruler(app,config)

use

基本使用

import { App } from 'leafer-ui'
import { Ruler } from 'leafer-x-ruler'

const app = new App({
  view: window,
  tree: {},
  editor: {},
})

// 实例化标尺插件
const ruler = new Ruler(app)

// 启用、禁用  
ruler.enabled = false

自定义配置示例

import { App } from 'leafer-ui'
import { Ruler } from 'leafer-x-ruler'

const app = new App({
  view: window,
  tree: {},
  editor: {},
})

// 实例化标尺插件,传入自定义配置
const ruler = new Ruler(app,{
  // 使用自定义的单位
  unit:'cs',
  // 添加自定义单位
  conversionFactors: {
    // 自定义单位cs
    cs: {
      px: 2,
      gaps: [5000, 2500, 1000, 500, 200, 100, 50, 20, 10],
      defaultGap: 1000
    }
  }
})

// 添加自定义主题  
ruler.addTheme('custom1', {
  backgroundColor: '#6cb0ab',
  textColor: '#a45454',
  borderColor: '#6f4593',
  highlightColor: 'rgba(22,93,255,0.75)'
})

// 切换主题  
ruler.changeTheme('custom1')

// 切换字体
ruler.changeUnit('px')

// 启用、禁用  
ruler.enabled = false

QA

// 如果使用侧边栏的伸缩时标尺宽高并未同步更新,或许是因为画布的大小并未改变无法触发resize事件;如果想改变画布的大小并使标尺同步,需要自行监听窗口大小变化,并触发leafer-ui的resize事件,以下是在vue3中使用的示例: 
<template>
  <div ref="divRef"></div>
</template>
<script lang="ts" setup>
  import {useResizeObserver} from "@vueuse/core";

  const divRef = ref()

  onMounted(() => {
      useResizeObserver(divRef, (entries) => {
        const [entry] = entries
        const { width, height } = entry.contentRect
        // 这步是为了触发leafer-ui的resize事件,标尺在监听到resize事件后会重新渲染
        leafer.app.resize({ width, height })
      })
  })
</script>

内置方法

RulerConfig

type RulerConfig = {
  /**
   * 是否启用标尺线
   */
  enabled?: boolean
  /**
   * 标尺线主题,默认light,可选(light:明亮,dark:暗黑)
   */
  theme?: string,
  /**
   * 单位 默认px,内置了px、cm、in、pt、pc、mm
   */
  unit?: string,
  /**
   * 标尺宽高
   */
  ruleSize?: number; 
  /**
   * 字体大小
   */
  fontSize?: number;
  /**
   * 主题,默认存在明亮、暗黑主图
   */
  themes?: {[key: string]: ThemeOption}
  /**
   * 定义单位转换因子 (每单位对应的像素数),(可从源码内查看预设定义)
   */
  conversionFactors?: {[key: string]: ConversionFactor}; 
}

ThemeOption

type ThemeOption = {
  /**
   * 背景色
   */
  backgroundColor: string,
  /**
   * 文字颜色
   */
  textColor: string,
  /**
   * 边框颜色

ConversionFactor

export interface ConversionFactor {
  /**

   */
  px: number

  /**
   * 缩放倍率,对应缩放比例:[0.02, 0.03, 0.05, 0.1, 0.2, 0.5, 1, 2, 5]
   */
  gaps: number[]

  /**
   * 默认缩放倍率(如果没有匹配到缩放比例对应的倍率,则使用默认值defaultGap)
   */
  defaultGap: number
}
