Somehow I saw code in the project of a neighboring team that generated a string with URL parameters for subsequent insertion into the iframesrc attribute.

This article may seem superfluous, obvious or too simple, but since this occurs in wildlife, you should not be silent about it, but rather share best-practices.

You don't know Redis (Part 2)

Website development *JavaScript *NoSQL *ReactJS *Serverless *

In the first part of You don't know Redis, I built an app using Redis as a primary database. For most people, it might sound unusual simply because the key-value data structure seems suboptimal for handling complex data models.

In practice, the choice of a database often depends on the application’s data-access patterns as well as the current and possible future requirements.

Redis was a perfect database for a Q&A board. I described how I took advantage of sorted sets and hashes data types to build features efficiently with less code.

Now I need to extend the Q&A board with registration/login functionality.

I will use Redis again. There are two reasons for that.

Firstly, I want to avoid the extra complexity that comes with adding yet another database.

Secondly, based on the requirements that I have, Redis is suitable for the task.

Important to note, that user registration and login is not always about only email and password handling. Users may have a lot of relations with other data which can grow complex over time.

Despite Redis being suitable for my task, it may not be a good choice for other projects.

Always define what data structure you need now and may need in the future to pick the right database.

How to create LinkedIn-like reactions with Serverless Redis

Website development *JavaScript *NoSQL *Node.JS *ReactJS *

As a side hustle, I teach tech recruiters web and software development technologies using plain English. It helps them with understanding job specs and resumes and it makes all of us, tech people, happier.

I run a weekly newsletter and often get feedback from recruiters via email or LinkedIn DMs.

I thought that I could try to collect feedback using the “Reactions” feature just like LinkedIn or Facebook does. It’s not as informative as personalised messages but is a simple feature that may incentivize more people to provide some general feedback.

Either way, it’s worth trying and as a software developer, I can’t wait to implement it.

This tutorial is about implementing a feature that will be used in real life on my project.

REST hooks for WebRTC Click to Call. Implementation experience

Flashphoner corporate blog Website development *JavaScript *Programming *Development of communication systems *

The "Click to Call" button on the website is an "innovation" that has been around for about 10 years. The technologies under the hood have changed, but the principle remains the same: someone clicks on the button on the site page, then JavaScript launches and requests access to the microphone and establishes a connection to the server — WebRTC SIP gateway. Further, the first client-server leg is a browser gateway, the second leg can be arbitrarily long and through the SIP proxy chain can eventually connect to a mobile or landline phone. Thus, the browser turns, in a sense, into a softphone and becomes a full participant in VoIP telephony.

Only 39% of the functions in node_modules are unique in the default Angular project created by ng new my-app.


I think the developers of open source solve problems in the same ways, because they study the same algorithms. Well, why be honest, they copy the popular solutions from StackOverflow also.

How I create browser applications inside browsers

JavaScript *Programming *HTML *Browsers DIY
Translation

GitJS


In 2013 Canonical tried to crowdfund Ubuntu Edge smartphone. Its main feature could be the ability to use the smartphone as a full-fledged PС. Unfortunatly, the crowdfunding campaign did not accumulate enough money, so a dream of having a universal device remained to be the dream.


I've been searching for universality, too, on the software side, not the hardware one. Today I can confidently say I found the necessary combination: Git and JavaScript.


As you know, I have already described the benefits of browser applications (nCKOB static site generator) and the benefits of using Git instead of yet another back-end with API (GitBudget to track personal spendings). Once GitBudget was out, I spent the remaining 2020 to build a system allowing one to create browser applications right inside browsers. GitJS is the name of that system.

Ant Design Component Customization and Bundle Optimization

VK corporate blog JavaScript *TypeScript *

I'm Ivan Kopenkov, a senior front-end developer at Mail.ru Cloud Solutions. In this article, I will tell you about the approaches we have used for the UI library components customization. You will also learn how to significantly decrease bundle size, cutting off all the unnecessary modules Ant Design takes there.

In our case, we are making wrappers for original Ant Design components inside the project, changing their appearance, and developing their logic. At the same time, we import both customized and original components right from the ant-design module. That saves tree shaking functionality and makes complex library components use our wrappers instead of original nested elements.

If you are already or about to use Ant Design, this article will provide you with a better and more effective way to do so. Even if you have chosen another UI library, you might be able to implement these ideas.

7 Best Practices Every Budding React.JS Developer Must Follow to Excel

Web design *JavaScript *Programming *ReactJS *
image

With the advancement in web technology, the entire globe is sliding towards the online tech sphere. The globe around us is going tech-centric day by day and thus the demand for front-end designers and developers also.

Whatever, be the purpose, people just google things and get their desired result. This is all because of the increase in the evolution of web and mobile app development. While we all know that to be a Web developer, you need to have basic skills of HTML, CSS, and JavaScript, but, with time React.js emerged into the technology stack of the web development field and outdated JavaScript.

A Report by JS reflects that 64.8% of the web developers prefer to use the React.JS framework and would love to use it again and again in the future. It has even beaten other categories of frameworks that are Vue.js with 28.8% votes and Angular with 23.9% votes. This is the reason why the demand for React.JS development companies is at an all-time high.

With React, it becomes painless to build an interactive user interface. It efficiently updates and renders the right components when changes are made.

Before you use React.js as web technology, let’s have a look at the practices that every React.js developer should follow to write better react codes for their application.

How to display a gazillion of metrics and keep your sanity

JavaScript *Data visualization *TypeScript *


I now have a new shiny blog. Read this article with the latest updates there https://blog.goncharov.page/how-to-display-a-gazillion-of-metrics-and-keep-your-sanity

Large scale equals distributed. Distributed equals inevitable complexity. Complexity at runtime equals extensive monitoring. At Hazelcast, doing distributed systems well is our bread and butter. It means we have no choice but to be huge fans of collecting all kinds of metrics to stay on guard of the data our users trust us with.


In Management Center 4.2020.08, we drastically changed the model of how we transfer the metric data from the cluster members to the Management Center, how we store it, and how we display it. In this post, we are going to talk about the latter bit of the triad.


We will discuss what to do when you want to display all the data at once, but your users have a limited number of monitors and only one pair of eyes. We will speculate about what users actually want to see when they look at a chart of a monitoring web app. We will go over different approaches to filter the data, and how an average, a median, and a definite integral play their key roles.

[Dribbble Challenge] — Coffee Ordering Animation

JavaScript *
Sandbox

Tutorial level: Beginner/Junior


Motivation


Sometimes, when we surf dribbble, uplabs and similar design clouds, we often find many concepts or prototypes with animations, micro interactions, application flow and so on.
I often find illustrations of mobile apps that are good and interesting, but of course they are still in the form of concept, so therefore, why don't we try to apply them as an interface for applications that we will build next.


Original concept


In the Dribbble Challenge we will try to build an interface for Coffee Ordering, as I found on Dribble.
