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 🙏

//  test code:


    const ZKLib = require('zklib-32ble')
    const test = async () => {
    let zkInstance = new ZKLib('192.168.1.201', 4370, 5200, 5000);
    try {
        // Create socket to machine
        await zkInstance.createSocket()


        // Get general info like logCapacity, user counts, logs count
        // It's really useful to check the status of device

        console.log(await zkInstance.getInfo())
      } catch (e) {
        console.log(e)
        if (e.code === 'EADDRINUSE') {
        }
    }


    // Get users in machine

    const users = await zkInstance.getUsers()
    console.log(users)


    // Create new user: setUser(uid, userid, name, password, role = 0, cardno = 0)
    
    await zkInstance.setUser(12, '9', 'testing', '111', 0, 0);


    // Get all logs in the machine
    // Currently, there is no filter to take data, it just takes all !!

    const logs = await zkInstance.getAttendances(function() {
       if (err) throw err;
       console.log("Very cool!");
    })
    console.log(logs)



    // You can also read realtime log by getRealTimelogs function

    await zkInstance.getRealTimeLogs((data)=>{
        // do something when some checkin
        console.log(data)
    })

    // Get the current Time in the machine

    const z = await zkInstance.getTime();
    console.log(z.toString());

    // Serial number

    const sr = await zkInstance.getSerialNumber();
    console.log(sr);

    // Firmware Version

    const fw = await zkInstance.getFirmware();
    console.log(fw);

    // PIN of the device

    const pi = await zkInstance.getPIN();
    console.log(pi);


    // Check Face functionality (Yes if ON, No if OFF)

    const fo = await zkInstance.getFaceOn();
    console.log(fo);
    

    // SSR (Self-Service-Recorder)

    const ssr = await zkInstance.getSSR();
    console.log(ssr);

    
    // Device Version

    const dv = await zkInstance.getDeviceVersion();
    console.log(dv);


    // Device Name

    const n = await zkInstance.getDeviceName();
    console.log(n);


    // Platform Version

    const p = await zkInstance.getPlatform();
    console.log(p);


    // OS Version

    const o = await zkInstance.getOS();
    console.log(o);


    // WorkCode of the machine

    const wc = await zkInstance.getWorkCode();
    console.log(wc);


    // Get Attendance size

    const s = await zkInstance.getAttendanceSize();
    console.log(s);

    // Delete the data in machine
    // Note: You should do this when there are too many data in the machine,
          // this issue can slow down machine.

    zkInstance.clearAttendanceLog();


    // Disconnect the machine ( don't do this when you need realtime update :)))
    await zkInstance.disconnect()

}

test()  // in the end we execute the function

 

There are many functions you can just visit zk protocol to see the command and put it in executeCmd function already existed in the library. The function executeCmd accepts the command constant in constants.js and the data if needed, and we can implement it as follows:

    async executeCmd(command, data=''){
        return await this.functionWrapper(
            ()=> this.zklibTcp.executeCmd(command, data),
            ()=> this.zklibUdp.executeCmd(command , data)
        )
    }

    // unlock the door  
    executeCmd(CMD.CMD_UNLOCK, '')
