Live: frontend performance

    A good UX, thoughtful design and intuitive interface are great stuff. But if this all lags, users leave you. Sometimes developers forget about it. With the topic of front-end productivity, my colleagues and I will continue the online series in which we discuss current issues of client-side development.

    The live broadcast dedicated to the performance will be held on December 18 on the YouTube channel AvitoTech. Experts from Yandex, Tinkoff, Mail.Ru and Avito will participate in the discussion. Under the cut - sample questions that we plan to discuss, and a link to the upcoming broadcast. After the meeting, update the post, post the video, add it to your bookmarks if you are interested in the topic.

    Sample discussion questions

    You can never predict which way the conversation will go. But here are the approximate topics for discussion that we have outlined with colleagues.

    • How to collect metrics from users?
    • How to work with measurement results and how they reflect reality?
    • How to find the slowest places in the project and eliminate them?
    • How can the environment help solve performance problems?
    • What tools to apply for all these tasks and do not dig?
    • And most importantly: how to preserve the result and spread the culture of performance in your company?

    In addition, we will try to answer questions that will be sent during the broadcast. And on those that appear in the comments on this post. Update our list.

    “In the context of the performance issues of the frontend, I would like to discuss optimization techniques to reduce rendering time, rendering, in general, approaches to performance analysis. And the main thing is how to link the labor costs for optimization with business indicators. ”

    I think it will be important to discuss how you can organize detailed monitoring of the performance of the code, both internal and external, what indicators you should look at when profiling and how to organize the "correct" collection of metrics and choose an environment for it. I will answer questions about the basic techniques for improving the performance and responsiveness of the interface.

    “In modern web applications, performance is important, because during intensive development and in an effort to compete in the market, applications begin to quickly“ fatten ”and, as a result,“ slow down ”. I would like to discuss how to prevent a drawdown in performance before the application gets into production. It is interesting to talk about the systematic approach to monitoring performance on the scale of dozens of SPA ”.

    “The modern web has long erased the line between the“ regular site ”and“ SPA / application ”, if before the struggle was only for access speed, now for the performance of the application itself. Therefore, I would like to discuss how to maintain a delicate balance between fast access and application performance, not only from the standpoint of bare metrics / numbers, but also on how user perception of performance can be influenced. ”
