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 🙏

实时通话

webrtc 支持实时通话功能。用户可以与好友进行实时视频聊天。

注意:视频通话功能只支持 https+Webkit 浏览器。

集成步骤

集成步骤如下:

  1. 安装。
	npm install easemob-webrtc
  1. 初始化 WebRTC Call 。webrtc依赖easemob-websdk,需要先集成easemob-websdk。
var rtcCall = new WebIM.WebRTC.Call({
    connection: conn, //easemob-websdk
    mediaStreamConstaints: {
            audio: true,
            video: true
    },

    listener: {
        onAcceptCall: function (from, options) {
            console.log('onAcceptCall::', 'from: ', from, 'options: ', options);
        },
        //通过streamType区分视频流和音频流,streamType: 'VOICE'(音频流),'VIDEO'(视频流)
        onGotRemoteStream: function (stream, streamType) {
            console.log('onGotRemoteStream::', 'stream: ', stream, 'streamType: ', streamType);
            var video = document.getElementById('video');
            video.srcObject = stream;
        },
        onGotLocalStream: function (stream, streamType) {
            console.log('onGotLocalStream::', 'stream:', stream, 'streamType: ', streamType);
            var video = document.getElementById('localVideo');
            video.srcObject = stream;
        },
        onRinging: function (caller, streamType) {
                        console.log("onRinging", caller)
        },
        onTermCall: function (reason) {
            console.log('onTermCall::');
            console.log('reason:', reason);
        },
        onIceConnectionStateChange: function (iceState) {
            console.log('onIceConnectionStateChange::', 'iceState:', iceState);
        },
        onError: function (e) {
            console.log(e);
        }
     }
});
  1. 调用 RTC 接口。
// 视频呼叫对方
    var call = function () {
        rtcCall.caller = 'mengyuanyuan';
        rtcCall.makeVideoCall('asdfghj');
    };
    // 音频呼叫对方
    var call = function () {
        rtcCall.caller = 'mengyuanyuan';
        rtcCall.makeVoiceCall('asdfghj');
    };
    // 关掉/拒绝视频
    var endCall = function () {
        rtcCall.endCall();
    }
    // 接受对方呼叫
    var acceptCall = function () {
        rtcCall.acceptCall();
    }
  1. 绑定事件。
document.getElementById('rtCall').onclick = call;
document.getElementById('rtEndCall').onclick = endCall;
document.getElementById('rtAcceptCall').onclick = acceptCall;

常见问题

Q:发起视频聊天时,收到提示“An error occurred when calling webrtc”,怎么办?

A:请开启浏览器使用摄像头的权限。以Chrome为例,在地址栏中输入chrome://settings/content,在“内容设置”页面下拉,找到“摄像头”,选择“当网站要求使用您的摄像头时询问您(推荐)”。
