On the way to durable applications with PSKOV static site generator as an example

Pskov's veche


Hi, my name is Michael Kapelko. I have been developing software professionally for more than 10 years. I develop games and game development tools in my spare time.


This article describes my first durable application for desktop PCs: PSKOV static site generator.


Durability


A durable application is an application that functions without a single change on operating systems released in years 2010-2030. In other words, a durable application has backward compatibility of 10 years and has the stability to run for 10 years. Actually, PSKOV runs even under Windows 2000, so PSKOV has backward compatibility of 19 years.

inb4: This is not another "setting up" a new project with Vue and TypeScript tutorial. Let's do some deep dive into more complex topics!


typescript is awesome. Vue is awesome. No doubt, that a lot of people try to bundle them together. But, due to different reasons, it is hard to really type your Vue app. Let's find out what are the problems and what can be done to solve them (or at least minimize the impact).

Angular vs. KnockoutJS: The Fundamental Differences and Similarities You Should Know

Reading time5 min
Views4.7K
It's extremely befuddling when it comes to choosing between two libraries and frameworks, especially when they are almost similar to each other.

I faced the same situation recently when I had to choose one from Angular vs KnockoutJS. The most perplexing part of the two is Angular is a JavaScript-based open-source front-end web development framework while Knockout is a library.

So, the selection is a bit complex task and, as I had to, you might need to go through a systematic and understand the two technologies or web development framework thoroughly.

So, you need to begin following the one-by-one method.

What is Framework?


A framework is a model on which you have to build your home. It is having a collection of blueprints which from which it choose the right one for you. In short, the framework is in charge of the flow and it chooses when and how to go.

What is the Library?


The library is like going to a furniture house to get some furniture for your home. Here you are in charge of the flow and you decide when to call the code.

Top 10 JavaScript Hack for Optimized Performance

Reading time5 min
Views4.5K

JavaScript has been ruling the tech arena for more than two decades and helping developers simplifying complex tasks. It allows developers to implement complex task web pages in a most simplified manner. For most of the developers minified JavaScript file is the common phenomena while very few developers may be aware of Optimized JavaScript code. While meeting through many Javascript developers, I have come to know that Optimized JavaScript code is something that confuses developers, some of them might be doing it, but they are not aware of this.


What is an Optimized JavaScript Code


When combinations of uniquely programmed logics along with small hacks utilized to enhance performance and speed is known as Optimized JavaScript code. Optimization not only optimizes performance and speed but also saves maximum development time. When you save time, you save some bucks as well.


So, I am here with some useful and fruitful hacks to help developers optimize performance, enhance speed and save time. Hope, you like the article and after going through it, you may utilize the best of Optimized JavaScript code.

Protocol for communication between iframe and the main window

Reading time4 min
Views5.1K

From time to time, developers need to establish communication between several browser tabs to be able to send messages from one tab to another and receive responses. We have also faced this need at some point.


Some solutions already exist (like, for instance, BroadcastChannel API). However, its browser support leaves a lot to be desired, so we decided to use our own library. When the library was ready, that functionality was no longer required. Nevertheless, another task emerged: communication between an iframe and the main window.


On closer examination, it turned out that two-thirds of the library would not have to be changed — only some code refactoring was necessary. The library is a communication PROTOCOL that can work with text data. It can be applied in all cases in which text is transferred, such as iframes, window.open, worker, browser tabs or WebSocket.


How it works


Currently, the protocol has two functions: sending messages and subscription to events. Any message in the protocol is a data object. For us, the main field in that object is type, which tells us what kind of message it is. The type field is an enum with the following values:

Sidecar for a Code splitting

Reading time12 min
Views981


Code splitting. Code splitting is everywhere. However, why? Just because there is too much of javascript nowadays, and not all are in use at the same point in time.


JS is a very heavy thing. Not for your iPhone Xs or brand new i9 laptop, but for millions(probably billions) of slower devices owners. Or, at least, for your watches.


So — JS is bad, but what would happen if we just disable it — the problem would be gone… for some sites, and be gone "with sites" for the React-based ones. But anyway — there are sites, which could work without JS… and there is something we should learn from them...

Get in the sidecar!
