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 🙏

目录

介绍

传统的 EventSource 类不支持流式数据上传请求头,如 Content-Type、Content-Length 等。本库基于 fetch API 实现了一个支持流式数据上传请求头的 EventSource 类。
该类继承自 EventSource 类,重写了 open 方法,使用 fetch API 实现了事件源的连接和消息的接收。
该类还提供了 onopen、onmessage、onerror 和 onclose 方法,用于处理事件源的连接、消息、错误和关闭事件。
本库的优点是:对比于其他库体积小,易于使用,支持流式数据上传请求头,支持自定义请求头和请求方法。

功能

1. 支持流式数据上传请求头,如 Content-Type、Content-Length 等。
2. 支持自定义请求头。
3. 支持自定义请求方法,如 GET、POST、PUT 等。

安装

npm install event-source-web

使用

import EventSourceWeb from 'event-source-web';

const url = 'URL_ADDRESS    const url = 'http://example.com/stream';

const headers = {
   'Content-Type': 'application/json',
}

const options = {
    method: 'POST',
    headers: headers,
    body: JSON.stringify({ key: 'value' }),
};
const es = new EventSourceWeb(url, options);

es.onopen = () => {
    console.log('连接已打开');

};

es.onmessage = (data) => {
    console.log('收到消息:', data);
};

es.onerror = (error) => {
    console.error('发生错误:', error);
}

es.onclose = () => {
    console.log('连接已关闭');
};
