Making Instagram.com faster: Part 1 - Instagram Engineering
In recent years, instagram.com has seen a lot of changes — they’ve launched stories, filters, creation tools, notifications, and direct messaging as well as myriad other features and enhancements. However, as the product grew, one unfortunate side effect was that their web performance began to suffer. Over the last year, they made a conscious effort to improve this. Their ongoing efforts have thus far resulted in almost 50% cumulative improvement to their feed page load time. This series of blog posts will outline some of the work they’ve done that led to these improvements.

Introducing Base Web, Uber’s New Design System for Building Websites in React
At Uber, they have hundreds of internal web applications used by developers, product managers, and operations teams—essentially everyone at the company. Since all web applications work differently, it puts additional overhead on our employees to learn how to interact with them most effectively. To solve these issues, Uber assembled a dedicated design and engineering team to come up with a universal system, which resulted in the Base Web design system. Open sourced in 2018, Base Web is a React component library implementing the Base design language that acts as a device-agnostic foundation for quickly and easily creating web applications.

React recently introduced a new way to deal with side effects: the useEffect hook. Translating lifecycle methods to useEffect calls can be confusing at first. It’s confusing because we shouldn’t be translating imperative lifecycle methods to declarative useEffect calls in the first place. This article breaks it down.
