On Thursday, April 19 at 19:00, the seventh UralJS rally will take place in the Titra loft. Let's discuss how React Native has opened the world of mobile development to JavaScript programmers, and then digress from specific technologies and speculate on what good navigation is and how developers really should work with dates and time.

Here is a detailed description of the reports:

Evgeny Tikhonov, Kontur - Let's have a look at DateTime

We are faced with dates and times, but do not always understand how they work. Because of this, Khabarovsk users send messages from the future, and leap year birthday men remain young for a day longer. Why it happens? You can crawl into the debugger each time, or you can sort out the modern model of time counting and the device of a DateTime object.

I will understand the basic concepts and principles of working with date and time without reference to a specific platform. I will tell you why the day is not always 24 hours, I will learn how to solve problems with the time shift and not be afraid of working with dates.

Innokenty Shushpanov, FastDev - Dive into React Native

Let's talk about React Native - how it works and why it is so cool. I'll tell you why we need and why native components and modules are so convenient. We will understand the tools, network stack and problem areas of the framework.

You can be sure that any JavaScript developer can easily write a mobile application on React Native.

Vyacheslav Bukharin, Kontur - Improving SPA Navigation

Developers and designers rarely think out the navigation in the SPA. In the meantime, inconvenient routing greatly affects the user’s perception of the product. Remember your own emotions when the application returns you to the previous photo, instead of the profile page, or to the beginning of the news feed, instead of post nine hours ago.

I will analyze the most annoying problems using VKontakte, Instagram, Facebook and talk about their approaches to building navigation. We will understand what and how can be improved without being tied to specific technologies. I will show how we approached the development of navigation in our own project.

Participation is free, but you must register so that the organizers prepare tea, coffee and snacks for all guests.

Records will appear on the YouTube channel after the mitap.
