Pixo - Image editor for your web app

posted in JavaScript on 2018-09-03

If your users deal with images (photos, product images, etc.) it will be great if they have the ability to apply some basic editing after upload, e.g. adjust brightness and contrast for sharper view, crop, add some text, etc. However, if image editing is not the primary feature of your product, the profit from investment in such secondary feature won't cover the costs. Integrating a 3rd party image editor appears to be a wiser choice.

posted in JavaScript on 2018-06-29

Long long time ago in a kingdom far far away there was an app. The app was supported by the well known React and Redux families but there was a problem. It was damn slow. People started complaining and the app had to do something. It had to deliver its content quickly so it provides better user experience. Then the server-side rendering was born.

React and separation of concerns

posted in JavaScript on 2018-05-27

Years ago when Facebook announced their JSX syntax we had a wave of comments how this was against some of the well established good practices. The main point of most people was that it violates the separation of concerns. They said that React and its JSX are mixing HTML, CSS and JavaScript which were suppose to be separated.


In this article we will see how React and its ecosystem has quite good separation of concerns. We will prove that markup, styles and logic may live in the same JavaScript land and still be separated.

Implementing an async queue in 23 lines of code

posted in JavaScript on 2018-05-07

Recently we had an interesting task at work. The user makes a selection of items and clicks a button. Then for every selected item we have to make a request to our API. The thing is that the user may click as many items as he/she wants. In order to speed up the process we decided to handle four requests in parallel and once some of them is finished we pull the next one. If you ask why exactly four requests in parallel read this paper.
