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 🙏

simple-telemetry

v0.1.2

Published

A simple telemetry library that tracks user actions

Readme

A Telemetry User Action library.

No instrumentation required

Add this to your top level index.js file

...

import { run } from "simple-telemetry";

...

const config = {
  user: "MyUser",
  appName: "Test App",
  idxAttribute: "data-testid",
  attributes: {
    "data-telemetry": {
      name: "data-telemetry",
      format: (value) => {
        return value.name;
      },
      processValue: (value) => {
        return value;
      },
    },
    "data-testid": {
      name: "data-testid",
      format: (value) => {
        return value.name;
      },
      processValue: (value) => {
        return value;
      },
    },
  },
  ignoreEvents: {
    click: "noTarget",
  },
  keepAliveDuration: 5000,
  api: {
    url: "http://localhost:3005",
    analytics: "/analytics",
    alive: "/alive",
    route: "/route",
  },
};

...

Note: There are still bugs and some things don't just work quite right yet...

  • every click is logged even clicks on background (This should change...)
  • uses sendBeacon from Beacon API
  • plain javascript

Config attributes

| Attribute | Description | Value | | ----------------- | :---------------------------------------------- | :-------: | | events | target DOM events | array | | target.attributes | attributes to be used for logging if they exist | array | | keepAliveDuration | how long before a user is considered to be idle | millisecs | | api.url | url for sendBeacon http calls | uri | | api.analytics | path for sendBeacon analytics http calls | string | | api.route | path for sendBeacon route http calls | string | | api.alive | path for sendBeacon alivehttp calls | string |

Events

Events to listen to can be specified (This is in flux as this may not be necessary)

Target Attributes

These are attributes that will be extracted and passed back through the API to the backend (if there is one)

backend API

  • url => the backend url i.e. http://my.backend.com this has to be a http backend as we are using BEACON API for sending events.

  • analytics => path of the analytics endpoint route

    • mouse event
    • keyboard event
  • route => path of the route endpoint route

    • route change event
  • alive => path of the keepalive endpoint route

    • idle event
    • busy event

Backend Server

Not my problem :-)

... that being said a simple express server should do

const express = require("express");
const bodyParser = require("body-parser");
const app = express();

// the server port
const port = 3005;

// body parser -> probably deprecated
app.use(bodyParser.text());

app.post("/analytics", (req, res) => {
  console.log("analytics", JSON.parse(req.body));
  res.sendStatus(204);
});

app.post("/alive", (req, res) => {
  console.log("alive", JSON.parse(req.body));
  res.sendStatus(204);
});

app.post("/route", (req, res) => {
  console.log("route", JSON.parse(req.body));
  res.sendStatus(204);
});

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`);
});
