GitHub – kzahel/web-server-chrome: An HTTP Web Server for Chrome (chrome.sockets API)

Posted by jpluimers on 2020/06/01

Cool: [WayBack] GitHub – kzahel/web-server-chrome: An HTTP Web Server for Chrome (chrome.sockets API)

This allows you to develop HTTP applications that live in Chrome:

[Archive.is1/Archive.is2] Web Server for Chrome – Chrome Web Store: A Web Server for Chrome, serves web pages from a local folder over the network, using HTTP. Runs offline.

Of course you could to python -m SimpleHTTPServer 8888 or python -m http.server 8888, but this runs within chrome and can be used from inside JavaScript projects.

Features

  • serve local files
  • configure listening port
  • configure listening interface (e.g. localhost or all interfaces)
  • custom http handlers possible
  • websocket support available
  • works nice with chrome.runtime.onSuspend
  • options for autostart, start in background, etc etc.
  • handles range requests, HEAD, etc
  • options for CORS
  • optional PUT, DELETE request (for upload files)
  • sets MIME types
  • can render directory listing
  • See relevant options: https://github.com/kzahel/web-server-chrome/blob/master/polymer-ui/options.js

Beyond console.log() – Matt Burgess – Medium

Posted by jpluimers on 2020/05/26

Not yet structured logging, but it brings more structure to your console.log() output:

There is more to debugging JavaScript than console.log to output values. It might seem obvious I’m going to pimp the debugger, but…

html frames and iframes from other sites that won’t load: some links

Posted by jpluimers on 2020/05/14

Back in the days, framing stuff from other sites would just work. Nowadays, often they don’t because of a variety of reasons, often the site not wanting to be embedded, which is OK with me.

But it pays knowing what they do and how they do it, to ensure it is not an accidental setting of the address bar URL to the wrong value like in

  if(top != window) {
    top.location = window.location
  }

So here are some links for me to dig deeper when I encounter framing issues again:

My basic idea for a workaround is to go through a proxy.

It looks like others had this idea too, so some links future reading via cors proxy – Google Search:

Web accessibility is hard, so please let your sites not become worse over time

Posted by jpluimers on 2020/05/11

Despite clear guidelines (European level since 2016, W3C level since 2018), web accessibility is still hard, both for web site developers and their users.

Two years ago, bumped into a Dutch government web site that had become worse over time: they disabled keyboard paste for numeric fields, only would paste 1 digit at a time, and managed to have the delete button delete the current digit (like what the backspace does and should do) instead of the next.

Please do not do that!

Here are the guidelines: [WayBack] Web Content Accessibility Guidelines (WCAG) 2.1

This is the (Dutch) story:

 [WayBack] Thread by @jpluimers: “Beste @Waternet, waarom kan ik niet meer het hele opnamenummer in 1 keer plakken? Cijfertje voor cijfertje uit de gescippen plakken is nogal veel werk. Vroeger ging dit wel goed. plakken werkt niet met het toetsenbord: alleen m […]”

[WayBack] Jeroen Pluimers on Twitter: “Beste @Waternet, waarom kan ik niet meer het hele opnamenummer in 1 keer plakken? Cijfertje voor cijfertje uit de gescande brief knippen plakken is nogal veel werk. Vroeger ging dit wel goed.… “

[WayBack] Jeroen Pluimers on Twitter: “plakken werkt niet met het toetsenbord: alleen maar met de muis, dus onhandig voor mensen met een beperking. Als je in het veld staat werken alleen de numerieke toetsen en pijltjes van je toetsenbord, en de delete knop haalt het verkeerde karakter weg. Wie verzint die ongein?”

[WayBack] Jeroen Pluimers Twitterissä: “Bij postcode werkt plakken weer wel (en de rest van het toetsenbord ook helemaal), maar bij meterstand weer niet. Hoe maak je je site onhandig voor mensen met een beperking les 1: het is helemaal gelukt. Jammer! Lees eens … en … “

[WayBack] Jeroen Pluimers Twitterissä: “Bij email adres werkt plakken weer wel (gelukkig, het zijn maar 40 karakters), maar er mist een cruciale stap: meternummer. Die controle is voor adressen met meerdere meters ontzettend belangrijk. Vroeger werd dat wel gecontroleerd. Het invoerproces is dus een achteruitgang.”

[WayBack] Jeroen Pluimers on Twitter: “Laatste probleem is een waarschuwing *achteraf* dat jullie geen email bevestiging kunnen sturen. Super onhandig, omdat je op dat moment de stand ook niet meer kunt afdrukken. Er is veel werk voor jullie aan de winkel. Hou me gaarne op de hoogte van de vorderingen. CC @matijn”

[WayBack] Jeroen Pluimers on Twitter: “Bij dit soort problemen denk ik altijd aan @matijn en anderen waar toegankelijkheid van onschatbaar belang is. Zo zonde dat organisaties het voor elkaar krijgen om dit te verslechteren in plaats van de verbeteren, ondanks de Europese richtlijnen uit 2016 “

The last thing you need to do when you cause link rot is to list the page as “online banking is down”

Posted by jpluimers on 2020/03/10

Nice example on how not to copy with link rot: as a bank is to indicate “internet banking is unavailable” scares your customers away.

[WayBack] Jeroen Pluimers on Twitter: “dit heet overigens link rot, en gebruiksvriendelijke sites proberen dat te voorkomen; is zeker niet gecompliceerd en eigenlijk ook niet complex: het is een kleine moeite om dat in je ontwerp en onderhoud-proces mee te nemen. 1/2 …

[WayBack] Jeroen Pluimers on Twitter: “de huidige down-melding zet sowieso je klanten volledig op het verkeerde been, dus daar moet zeker iets aan gebeuren. 2/2 “I.v.m. een storing kunt u geen gebruik maken van Internet Bankieren. Internet Banking is unavailable”…”

Do I really need to write a WordPress API wrapper to check the status of “missed schedule” posts?

Posted by jpluimers on 2020/01/29

After years with “missed schedule” posts on (paid!) wordpress.com based sites, WordPress has documented that the scheduler officially does not support more than 100 posts:

[WayBack] Warning: Please do not schedule more than 100 posts. Any posts scheduled beyond that amount will not be published.

In practice this is not fully true, so lets explain that a little.

Background

Imagine the list of scheduled posts as a list of posts to be posted anywhere from the near future (lets call that tail) until far in the future (for now head).

As long as you schedule posts in head to tail order, then there is no problem. You can schedule 100s of posts (usually I’ve between 700 and 1200 posts scheduled that way).

The problems appear when:
