An example of using Electron + React JS and a native ffmpeg addon to access a webcamera

This guide may be helpful to someone who is trying to find a way
to work with Electron if they need to use a c++ library or code

I was looking for a more realistic example than a simple 'hello world' and i didn't succeed

Here are the links in advance:

- electron - https://github.com/khomin/electron_camera_ffmpeg

- addon - https://github.com/khomin/electron_ffmpeg_addon_camera

Making economic RTS with React and Babylon. Part 1

Game development *WebGL *ReactJS *
Tutorial

When I was much younger, I used to play a lot. My number one preference was Knights & Merchants. While all my friends liked battle scenes most, I was fond of economical aspects of this game. For me it was always cool to look after the villagers who run their own business, become hungry sometimes and work together in the name of their country’s welfare. Recently I bought it in Steam store and thought that I could even do a webmake of this game.

As a first step of this dangerous journey it would be cool to take one of the core mechanics and try to re-implement it with the tools I’m already comfortable with: React and WebGL. It’s also a great possibility to test drive Babylon.js, which is in my to-do list.

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.

You don't know Redis

Website development *NoSQL *ReactJS *Serverless *
Tutorial

Originally posted on DEV.to

In my previous post, I touched on the point that Redis is more than just an in-memory cache.

Most people do not even consider Redis as a primary database. There are a lot of use cases where Redis is a perfect choice for non-cache related tasks.

In this article, I will demonstrate how I built a fully functional Q&A board for asking and upvoting the most interesting questions. Redis will be used as a primary database.

I will use Gatsby (React), Netlify serverless functions and Upstash Serverless Redis.

Upstash has been a good choice so far and I decided to try it out in a more serious project. I love everything serverless and how it makes things simpler for me.

Serverless will be a great choice for most tasks however you need to know the pros and cons of the tech you are using. I encourage you to learn more about serverless to get the most out of it.

Only 39% of the functions in node_modules are unique in the default Angular project

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.

10+ Biggest Remote Tech Jobs Aggregators Comparison

ReactJS *Personnel Management *IT career Social networks and communities Remote work

There is a myriad of articles about where to find remote jobs, particularly in tech. Some of them are outdated and most of them don't provide detailed reviews. So that's why I decided to do my own research. I did a basic search by "React" skill (where possible) and expected to see mostly "Frontend Developer" vacancies.

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.

React Token Auth

JavaScript *ReactJS *
Sandbox


Problem


Authorization is one of the first problems developers face upon starting a new project. And one of the most common types of authorization (from my experience) is the token-based authorization (usually using JWT).


From my perspective, this article looks like "what I wanted to read two weeks ago". My goal was to write minimalistic and reusable code with a clean and straightforward interface. I had the next requirements for my implementation of the auth management:


  • Tokens should be stored in local storage
  • Tokens should be restored on page reload
  • Access token should be passed in the network requests
  • After expiration access token should be updated by refresh token if the last one is presented
  • React components should have access to the auth information to render appropriate UI
  • The solution should be made with pure React (without Redux, thunk, etc..)

Abstract


Due to the never-ending increase in volume of vehicles surrounding our daily lives, Automatic Number Plate Recognition (ANPR), has become an evolving solution for managing and monitoring vehicles worldwide to enforce rules and prevent criminal activities, such as parking violation, red light violation, speeding, and vehicle theft. Although there is already a variety of public and private methods and libraries that have been developed and are used to achieve the automatic recognition of car license plate numbers around the world, there has not been much focus on making advancements toward a cross platform ANPR solution that supports all vehicle license plates worldwide. This paper introduces the Plate Vision project, a web and mobile application built on Ruby on Rails and React Native, which aims to serve as an alternative ANPR platform that supports detection of all license plates worldwide by utilizing various open source optical character recognition (OCR) libraries and making efficiency optimizations.

Key words and phrases: ruby, rails, react native, license plate recognition, plate region extraction, optical character recognition (OCR), ANPR.
