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 package to add timestamps to console.* statements, as well as a means to extend the console object for alternative logging methods

Readme

@saeon/logger

A tiny package that adds timestamps to the info, log, warn, and error functions on globalThis.console, and allows for extending console with bespoke functions. Functions for logging to a service via HTTP or GraphQL are included in the package with examples below. The signature of the original object is preserved (unless extended obviously).

Installation

npm install -s @saeon/logger date-fns @babel/runtime

Basic usage

import '@saeon/logger'

// All console logging functions now have a timestamp
console.log(msg)
console.info(msg)
console.warn(msg)
console.error(msg)

Extend / configure the console object

To unhelpfully print 'hello world' every time console.log() is called:

import { configure } from '@saeon/logger'

/**
 * Call the configure function with a callback that exposes the
 * global.console object and the current date-fns formatter
 *
 * Your callback needs to return an object with this signature
 * {
 *   overwrites: {
 *     ... the console.* properties/fns you would like to overwrite
 *   },
 *   timestampFormat: ... date-fns format string (or null)
 * }
 */
configure(({ console, timestampFormat }) => {
  return {
    overwrites: {
      // But note that console.log then won't have a timestamp, since you are overwriting the overwritten console.log function
      log: () => console.log('hello world'),
    },
    formatter: timestampFormat,
  }
})

Log to a webserver

Another potential use of this library is to extend the console object to log to a URL endpoint - there is built-in support for logging to HTTP endpoints as well as GraphQL endpoints (using the @apollo/client library)

Configure HTTP logging

npm install node-fetch # // If NOT a browser environment
import fetch from 'node-fetch' // If NOT a browser environment
import { logToHttp } from '@saeon/logger/log-to-http'
const httpUri = 'https://your API address here.co.za/log'
const batchingInterval = 2000

configure(() => ({
  overwrites: {
    http: logToHttp(httpUri, batchingInterval),
  },
}))

Configure GraphQL logging

First install @apollo/client

npm install @apollo/client

Then configure a link object (Refer to the ApolloClient documentation on how to configure a GraphQL link)

import { logToGql } from '@saeon/logger/log-to-graphql'
import gql from 'graphql-tag'

const link = new HttpLink({ uri: 'your graphql endpoint' })
const batchingInterval = 1800 // 1800 ms = 1.8 secs batching interval

configure(() => ({
  overwrites: {
    gql: logToGql({
      link,
      query: gql`
        mutation logBrowserEvents($input: [BrowserEventInput]!) {
          logBrowserEvents(input: $input)
        }
      `,
    }, batchingInterval),
  },
}))

Or both HTTP, GraphQL, with formatter specified and overwriting the console.error function

configure(({ console }) => {
  return {
    overwrites: {
      error: () => console.log('hello world'),
      gql: logToGql({ link, query }, 2500), // see above
      http: logToHttp(httpUri, 1500), // see above
    },
    formatter: 'yyyy-MM-dd', // https://date-fns.org
  }
})

And now you have the following console.* methods available in your browser or in your webserver

console.log(msg)
console.info(msg)
console.error() // always prints 'hello world'
console.http(msg)
console.gql(msg)

Batching network requests

Both the console.http and console.gql functions batch requests - the maximum rate at which servers are sent information is once per 5 second interval. This makes these functions suitable for logging even very many requests to the server.

This is an example of logging batches of mousemove events every 2 seconds (the default batching interval). Debouncing events that are fired often is good practice:

const debounce = (cb, duration = 0) => {
  var timer
  return (...args) => {
    clearTimeout(timer)
    timer = setTimeout(() => cb(...args), duration)
  }
}

document.getElementsByTagName('body')[0].onmousemove = debounce(({ x, y }) =>
  console.http({ x, y, etc })
)
