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 🙏

Readme

uni-perms-loader

简介

一个 webpack 自定义 loader,用于 uni-app 自定义指令 v-perms:xxx 转 v-if="$perms('xxx')",让 uni-app 具有自定义指令开发体验实现按钮权限。

安装依赖

npm 方式

npm i -D @lbingxin/uni-perms-loader

yarn 方式

yarn add @lbingxin/uni-perms-loader -D

使用方式

vue.config.js 配置

// vue.config.js
module.exports = {
  // 为.vue文件新增一个uni-perms-loader的loader
  chainWebpack: (config) => {
    config.module
      .rule("vue")
      .test(/\.vue$/)
      .use("@lbingxin/uni-perms-loader")
      .loader("@lbingxin/uni-perms-loader")
      .end();
  },
};

按钮权限判断方式实现

// src/utils/index.js

// 这边是假数据,不同团队对于权限的数据定义都不大一样,我列举的算是最简单的一种,不大需要
// 去考虑不同页面按钮名称重复,用当前页面路由进行区分
const data = {
  "/pages/index/index": {
    add: "新增",
    edit: "编辑",
  },
  "/pages/me/index": {
    add: "新增",
    auth: "授权",
  },
};
const checkPermission = (key) => {
  // 获取所有路由栈
  const pages = getCurrentPages();
  const len = pages.length;
  // 获取当前页面路由 route的值例如 pages/index/index
  const { route } = pages[len - 1];
  // 判断当前页面是否包含对应按钮的权限
  return !!data[`/${route}`][key];
};
export default checkPermission;

$perms 方法挂载

// main.js

// 将实现按钮权限判断的函数挂载到全局的$perms上

import checkPermission from "./utils/index";
Vue.prototype.$perms = checkPermission;
