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 🙏

使用示例

现有如下NPM包obj

class _CRS {
    constructor() {
        this._baidu = "baidu";
    }

    ESPG() {
        return "CRS.ESPG";
    }

    get Simple() {
        return "CRS.Simple";
    }

    get Baidu() {
        return this._baidu;
    }

    set Baidu(val) {
        this._baidu = val;
    }
}

const Obj = {
    Map: "Obj.Map",
    Control: function() {
        return "Obj.Control";
    },
    Layers: [1, 2, 3, 4],
    CRS: new _CRS()
};

export default Obj;

发布者

obj授权

import License from "js.license";

// 定义授权清单
const manifest = {
    Control: 1,
    CRS: 1,
    "CRS.Simple": 1,
    "CRS.Baidu": 1,
    "CRS.ESPG": 2,
};

class _CRS { ... }

const Obj = { ... }

var license = new License(manifest);

export default license.proxy(Obj);

License内置了免费版(Free, 0)基础版(Basic, 1)标准版(Standard, 2)高级版(Advanced, 3)四个软件版本。

  • Obj.ControlObj.CRSObj.CRS.SimpleObj.CRS.Baidu可以在Basic(1)版本下访问
  • Obj.CRS.ESPG可以在Standard(2) 版本下访问
  • 对于没有提到的Obj.MapObj.Layer可以在Free(0)版本下访问

使用者

首先从发布者那里拿到licenseKey,否则只能使用免费版。

import Obj from 'obj';

Obj.licenseKey='...'

如果没有拿到licenseKey,使用者只能访问如下的Obj

{
    Map: "Obj.Map",
    Control: {},
    Layers: [1, 2, 3, 4],
    CRS: {}
}
