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 🙏

forge-room 代表白板实时房间, 实时房间为房间里的用户提供包括白板在内的各种实时协作应用。

构建房间实例

构建房间实例之前, 需要调用服务端 API 创建房间获取房间 token, 参考 创建房间. forge-room 只复用了互动白板房间的房间号以及 token, 其他房间管理类的服务端 api 对 forge-room 无效. 对于 token 只要求有效, 不要求可写权限.

import { Room } from "@netless/forge-room";
import { RTMProvider_2_1 } from "@netless/forge-rtm";
import { WhiteboardApplication } from "@netless/forge-whiteboard";

// 通过 rtm 提供信令通道
const rtmProvider = new RTMProvider_2_1(rtmClient);

const room = new Room(
    "f6eeec407a4511ef993c1915959e3b73", /* room id */
    rtmProvider
);

// 进入房间之前, 需要注册房间里将会用到的实时应用
wbRoom.applicationManager.registerApplication(WhiteboardApplication);

await wbRoom.joinRoom({
    userId: "userId",
    nickName: "nickName",
    roomToken: "roomToken", // 白板房间 token
    sdkConfig: {
        region: "cn-hz",
        appIdentifier: "appIdentifier"
    }
});

管理房间应用

加入房间成功后, 可以通过 Room.applicationManager 管理房间应用.


// 加载上面注册的白板应用
const whiteboard = await wbRoom.applicationManager.launchApplication(WhiteboardApplication, {
    width: 1920,
    height: 1080,
    defaultToolbarStyle: {
        tool: "curve"
    }
}, "MainWhiteboard");

// 应用加载之后可以进行样式配置, 并挂载到 dom 上
whiteboard.view.style.height = `100vh`;
whiteboard.view.style.width = `100vw`;
whiteboard.view.style.background = "#9E9E9E";

document.body.appendChild(whiteboard.view);

appId

房间内每个应用都有唯一的 appId, 可以通过 Room.applicationManager.launchApplication 的第三个参数可以指定 appId 或者留空使用随机的 uuid. appId 划分了 一块房间数据, 房间里所有用户都可以无冲突的访问和修改这块数据.

何时应该手动指定 appId ?

以白板应用举例, 如果房间里的每个用户都要在同一个白板应用上写画, 那么应该指定一个 appId, 这样新加入的用户调用 Room.applicationManager.launchApplication 时会读取 已经存在的数据, 而不是用随机 uuid 新建一个白板应用.

何时应该用默认的 uuid ?

还是以白板应用举例, 如果要响应用户操作新建一个白板应用, 那么应该用默认的 uuid 创建一个新的应用实例.

view

对于每个应用实例, 都存在一个 view 属性对应到平台相关的 view 对象. 例如 JavaScript 中, 对应一个 DOM 对象. forge-room 只负责管理应用的创建、数据同步以及销毁. 不包含任何 UI, 所以你需要对 view 进行样式配置并挂载到你的 app 中的某个容器元素上.
