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 🙏

权限判断

hasPermission 指令

这是一个基于 Vue3 进行封装的自定义指令,在这个插件中,你可以检查传入的系统权限列表和用户拥有的权限列表,来确定用户是否具有某个组件/按钮级别的权限,实现更细粒度的权限控制。

使用方法

  1. 在你的项目根目录中新建一个permission文件夹,并在文件夹下新建一个index.ts文件和一个modules文件夹。

modules文件夹用来放置不同模块的权限控制文件(一般各个模块各自建一个.ts文件),而index.ts用来遍历读取modules下的所有文件,并将所有文件转换为键值对的形式,整合成一个包含系统所有权限信息的对象,即:{ 模块名:{ 该模块的权限列表 }, ... }。

  • 在index.ts文件中键入以下代码:
/**
 * 权限配置模块文件,统一引入所有权限配置文件
 */
const files = import.meta.glob('./modules/*.ts');
const modules = {};
for (const path in files) {
  files[path]().then((mod) => {
    let fileNameMatch = path.match(/([^\/\\]+?)\.\w+$/);
    let fileName = fileNameMatch ? fileNameMatch[1] : null;
    modules[fileName as string] = mod?.default
  });
}

export default modules
  • 在modules下新建所需要的模块文件,文件中的内容格式形如以下例子(权限key值: 权限标识):
export default {
    add: '/add-add',
    delete: '/delete-delete', 
    edit: '/edit-edit', 
}
  1. 引入index.ts中整理好的系统预先配置的权限列表,作为我们所需要的参数permissionList,。
import permissionList from './permission'
  1. 通过接口获取当前用户的权限列表,作为我们所需要的参数permissions。
import permissions from '存放服务端返回接口权限列表数据的地方'

permissionList形如:

{
    "admin": {
        "add": "/admin-add",
        "delete": "/admin-delete",
        "edit": "/admin-edit"
    },
    "user": {
        "add": "/user-add",
        "delete": "/user-delete"
    }
}

permissions形如:

[
    "/user-add",
    "/user-delete"
]
  1. 在项目中的入口文件中引入 v-permission,将前面提到的两个参数作为选项,然后使用插件并传入选项:
import { createApp } from 'vue'
import App from './views/App.vue'
import permission from "v-permission" 
import permissionList from './permission'
import permissions from '存放服务端返回接口权限列表数据的地方'

const app = createApp(App);

const options = {
    permissionList,
    permissions
}

app.use(permission, options)

app.mount('#app')
  1. 在文件中使用。
  • 以指令的方式使用:

    • v-permission指令形式:

      <el-button v-permission="{ module: '模块名', auth: '权限key值' }"> 有权限则显示 </el-button>
    • v-if指令形式:

      <el-button v-if="hasPermissions({ module: '模块名', auth: '权限key值' })"> 有权限则显示 </el-button>
  • 以方法的方式使用:

    import { inject } from "vue";
      
    // 注入权限判断方法 hasPermissions
    const hasPermissions = inject("hasPermissions");
    if (hasPermissions({ module: '模块名', auth: '权限key值' })) {
      console.log("用户有权限");
    } else {
      console.log("用户没有权限");
    }
