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

首先,您需要在您的项目中安装该npm包。您可以使用npm或yarn进行安装。

bash
Copy
npm install vue2-event-source
bash
Copy
yarn add vue2-event-source

使用

安装完成后,您可以在Vue应用中使用该npm包提供的组件、函数和插件。下面是一个简单的示例代码:

<template>
  <div class="app">
    <Chat :username="username" :url="url" />
  </div>
</template>

<script>
import { Chat, createEventSource, EventSourcePlugin } from 'vue2-event-source';

export default {
  name: 'App',
  components: {
    Chat
  },
  plugins: [
    EventSourcePlugin
  ],
  data() {
    return {
      username: '',
      url: ''
    };
  },
  created() {
    // 在created钩子中使用createEventSource创建EventSource对象
    createEventSource('/api/events').then((eventSource) => {
      this.url = '/api/events';
      this.username = 'user_' + Math.floor(Math.random() * 100);
    }).catch((error) => {
      console.error('EventSource error:', error);
    });
  }
};
</script>

在上面的代码中,我们首先导入了Chat组件、createEventSource函数和EventSourcePlugin插件。然后,在Vue组件的created钩子中,我们使用createEventSource函数创建了一个EventSource对象,并将其URL地址设置为/api/events。接着,我们将EventSourcePlugin插件添加到Vue应用中,并将Chat组件添加到Vue组件中。最后,我们将创建的EventSource对象的URL地址和随机生成的用户名传递给Chat组件作为props,以创建一个聊天室。

在Chat组件中,我们使用inject API来访问eventSource对象,并在created钩子中注册了一个名为message的事件监听器,用于接收其他用户发送的聊天消息。在beforeUnmount钩子中,我们清空了聊天记录。

在实际使用中,您可以根据自己的需求进行调整和修改。例如,您可以将Chat组件的样式进行修改,使其更符合您的设计要求;您也可以将createEventSource函数的URL地址进行修改,以连接到您自己的后端API。

也可以只使用 createEventSource, EventSourcePlugin;
