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:

Men’s Java is not JavaScript Annoyed Programmer/Developer T-Shirt

Posted by jpluimers on 2020/05/13

Though the shirt is not available on Amazon [WayBack] any more, still – after 25 years – so many recruiters still get it wrong.

Not just recruiters, so: [WayBack] Why is JavaScript called JavaScript, since it has nothing to do with Java? – Stack Overflow, thanks to CMS [WayBack]:

From an interview made to its creator Brendan Eich:

InfoWorld: As I understand it, JavaScript started out as Mocha, then became LiveScript and then became JavaScript when Netscape and Sun got together. But it actually has nothing to do with Java or not much to do with it, correct?

Eich: That’s right. It was all within six months from May till December (1995) that it was Mocha and then LiveScript. And then in early December, Netscape and Sun did a license agreement and it became JavaScript. And the idea was to make it a complementary scripting language to go with Java, with the compiled language.

he continues on the relation of ECMAScript based languages:

JavaScript, was originally named Mocha, later it was renamed to LiveScript, and then to JavaScript.

The LiveScript to JavaScript name change came because Netscape and Sun did a license agreement.

The language was then submitted for standarization to the ECMA International Organization. By that time, Netscape didn’t allow the use of the “JavaScript” name, so the standarized language is named ECMAScript.

JavaScript isn’t actually an open name. Now it’s a trademark of Sun (now Oracle).

There still a lot of confusion, some people still think that JavaScript, JScript, and ECMAScript are three different languages.

ECMAScript is the “standards” name for the language.

JavaScript is technically a “dialect” of ECMAScript, the Mozilla Foundation can use “JavaScript” as the name of their implementations (currently present on the Rhino and SpiderMonkey engines).

In the early days, Microsoft decided also to do what Netscape was doing on their own browser, and they developed JScript, which is also an ECMAScript dialect, but was named in this way to avoid trademark issues.

Forde’s Tenth Rule, or, “How I Learned to Stop Worrying and ❤ the State Machine”

Posted by jpluimers on 2020/04/01

It is important to look beyond your own comfort zone to see what other languages can support: [WayBack] Forde’s Tenth Rule, or, “How I Learned to Stop Worrying and ❤ the State Machine”.

The article is about implementing finite state machines in JavaScript with as little usage of string literals as possible.
