What you should (and shouldn’t) enable in Cloudflare for web performance

Cloudflare is a web-performance-and-security-as-a-service company.

To configure your web app to run faster, you need to:

• sign up for Cloudflare
• connect it to your site (by moving DNS records and setting up proxying)
• enable a few toggles in the settings.

How to code review?

• Review is a top-priority task. Review code soon as possible. It can help to avoid massive merge of PRs at the end of sprint and won’t waste time of team members, especially if tasks are related to each other.
• First of all you should check if the changes are related to the task. There shouldn’t be a thing like “let me also add this stuff to this PR by the way”.
• Initial PR comment should contain the link to corresponding trello card.
• You should not only check the code, but also check if the modified component is working correctly in the app. You check the code very carefully, every line. When checking the component in the app, you should test all possible use cases.
• The code should follow established code style and styled with prettier. Also, please follow English language rules and use common sense when naming variables. Do not repeat yourself, but keep it simple.
• Code review is not for critics, it’s rather a place for common effort to make a better product. That’s why it is

Как поместить scroll-контейнер во flexbox и не облажаться.

Столкнулись с проблемой: блок со скролом распепячивает flex. Давайте разбираться.

4 месяца назад показалось, что хак найден, о чём мы поспешили рассказать в твиттере, но потом стало ясно что таки поспешили.

Помотрели в спеку и mdn, но ключей к решению не нашли.
