We invite to the conference on web development on November 29

Friends, on November 29, in the Moscow office of the Mail.Ru Group, there will be a conference for frontend developers dedicated to web development in the mobile and “large” segments of the network. The audience will be addressed by specialists working on Mail.Ru Mail, Odnoklassniki, Mail.Ru Cloud and Document Editor projects.

Conference program:

Andrei Sumin , head of development of the client part of Mail.Ru, will present the report “Redesign, not a single user has suffered”.

We often hear how to develop, write tests and profile software code. But rarely do companies share the experience of rolling out new code for production. Andrey will tell about the stages of rolling out new mail design for millions of users.

Ivan Chashkin , developer of the touch of Mail.Ru Mail, called his speech "Battery in the phone, how to save".

Technologies are evolving, processors are becoming faster, and more memory. And only one remains almost unchanged, the battery and the day the device works. In the report, Ivan will show the most low-level battery consumption on the example of the iPhone 6, and we will try to understand where the charge goes.

Egor Dydykin , head of the development team for the main page, will tell you how to “Make and roll out a general block to the whole portal”. It will highlight the process of developing and implementing a single cross-portal component that is integrated into different environments with different needs and tasks.

1. Dynamic building of client-configurable blocks, rebuilding and rearranging.
2. The complexity of the calculations and implementation.
3. The organization of asynchronous API for interaction with the project.
4. The theme of components.
5. Profit

Alexander Rusakov , the developer of Mail.Ru Editor, will talk about the long journey that he had to go through in order to accomplish the task he had set - viewing and editing office documents in the browser. Displaying on the client side text with complex formatting, pictures and diagrams does not seem to be a difficult task, until there is a requirement to achieve identical display in different browsers.

The report will cover the following topics:

• problems of using standard methods for calculating text sizes and displaying a document using HTML and SVG;
• why we abandoned the use of nested data structures when editing and what we use instead of them;
• how we switched to Canvas, its advantages and disadvantages for us;
• how the same code works on both the client and the server; our experience using Node.js.

Konstantin Lebedev , a leading JavaScript developer for Mail.Ru Mail, has been developing Open Source solutions for the past few years. He has experience in implementing, promoting and supporting solutions both within the company and abroad.

In his report “JSSDK: From bicycle to car,” he will tell you what to look for if you want to write a “solution from scratch”. When to use ready-made solutions, and when to write yourself. What steps need to be done so that your work is not in vain and benefits others. All these nuances will be considered on the example of the internal framework, which arose as a result of the need to merge the code base of the two projects.

Dmitry Lyapunov , front-end developer of the Odnoklassniki mobile version, will talk about the features of developing interfaces for mobile devices that remain in the shadows until you touch a mobile phone. It will show what the debugging process consists of, what unexpected difficulties sometimes have to be encountered, and how they are overcome.

• Mobile features - what is built interaction with the user of the mobile device, why it is not easy, and the developer even harder.
• Layout - the ancient art of moving pixels across the screen in the name of the user, and here has its own characteristics associated with the limited mobile devices (nothing personal) and the diverse animal world of their browsers.
• JavaScript - you didn’t think that such a special mobile world didn’t touch your favorite JavaScript? Of course, here there are some strange approaches, usually related to the optimization and character of the device.
• Inspection is something that can suddenly turn the life of a mobile developer into hell. Outline a plan for how to go through these 9 circles and get out with the maximum saved consciousness.

As usual, the address of our office is Leningradsky Avenue 39, building 79. Do not forget to register and take a passport or driver's license. The gathering of guests begins at 9.00, and the conference itself starts at 10.00.
