A few weeks ago, the Apache Software Foundation (the ASF) made a decision to list the BSD + Patents license as a Category-X license. This move affects users of much of Facebook’s open source software, but especially the popular React project and the constellation of projects around it. As a result, many have asked us to consider relicensing React and all of our other open source projects. What has become clear through these discussions is that the ASF has very different considerations than Facebook does for how it maintains and distributes open source software.
When it comes to APIs, change isn’t popular. While software developers are used to iterating quickly and often, API developers lose that flexibility as soon as even one user starts consuming their interface.
Over the past decade, millions of developers have interacted with the Heroku CLI. In those 10 years, the CLI has gone through many changes. We’ve changed languages several times; redesigned the plugin architecture; and improved test coverage and the test framework. What follows is the story of our team’s journey to build and maintain the Heroku CLI from the early days of Heroku to today.
In this post, we’ll go over the pros and cons of various pagination strategies and discuss how these influenced our latest pagination scheme.
Recently, there’s been some buzz around the next great architectural shift in systems. There is a rising interest in the evolution of decentralized edge computing as a core part of that shift. For over two years, npm has been using edge computing concepts to ensure that the developer experience for users of npm Enterprise, our private registry product, matches the experience of using the centralized, cloud-hosted version of the npm Registry. Here’s why we’re doing that, and how.
最近几年，GitHub 受益于 Ruby on Rails，将 github.com/api.github.com 基础设施构建完整。现在我们走到了下一个里程碑：所有的应用和 API 请求由 Kubernetes 集群提供服务，将 GitHub 移植到 Kubernetes 是一件非常有趣的事儿，跟大家分享一下。

V8 is Google’s open source JavaScript engine. Chrome, Node.js, and many other applications use V8. This article explains V8’s bytecode format — which is actually easy to read once you understand some basic concepts.
手Q上很多页面首屏打开速度居高不下，甚至有些耗时达到3s以上，这意味着用户打开页面必须经过3秒之后才能进行交互操作，体验相当差，很多用户忍受不了这个漫长的时间直接流失掉了。为了提升用户体验和业务用户留存率，我们很多业务一开始通过Web开发，等页面模型验证符合预期后，再将H5页面转化成原生界面。我们很快意识到这不是一种健康的可持续的开发模式，一方面存在重复人力浪费，另外一方面原生商城除了速度快一点，要运营活动改版都很难。所以后来团队改了切入方向，安排人力专心研究如何加快页面打开速度，经过了一系列的摸爬滚打和优化探索，最终我们研发出了VasSonic框架，让H5页面首屏达到秒开，给用户一个更好的H5体验。下面就和大家分享VasSonic框架的发展历程。
「弹性安全网络」不是对现有技术的一种应用，它是真正的发明了一项此前所没有的技术，提出了一种全新的方法，采用了一个全新的角度来看待现有世界。弹性安全网络真正想要去做的，是替换掉整个互联网最核心的心脏，替换掉DNS，从而让网络变得有弹性，能够快速调度资源，形成一个全新的网络架构。

In this five part series, we will “recreate” React from the ground up, learning how it works along the way. Once we’ve finished, you should have a good grasp of how React works, and when and why it calls the various lifecycle methods of a component.
There is a very common mistake that I see in React components from beginners and experts alike. Sometimes I even find myself typing it, even when I know it’s a mistake. That’s because it feels so right. But if you’re going to write the best React code you can, you need to train yourself to spot this problem and avoid it. The mistake I’m referring to is creating functions in the render() method of a component.
In this article, we’ll discuss how Object.prototype.toString() performs in the V8 engine, why it’s important, how it changed with the introduction of ES2015 symbols, and how the baseline performance can be improved by up to 6x (based on findings from Mozilla engineers).
Sometimes modern Javascript projects get out of hand. A major culprit in this can be the messy handling of asynchronous tasks, leading to long, complex, and deeply nested blocks of code. Javascript now provides a new syntax for handling these operations, and it can turn even the most convoluted asynchronous operations into concise and highly readable code.
I’m going to type lots of words soon, but the gist of it is this: if you’re making a site, and you’re just about to go searching for that perfect web font, please, at least consider using system fonts instead.
You don’t need a native phone app to scan QR codes —it’s quite simple to create your own QR code reader. Your website running on a smartphone equipped with a camera and running a little JavaScript can do the same trick.
In this blog post, I would like to introduce the JavaScript Binary AST, an ongoing project that we hope will help make webpages load faster, along with a number of other benefits.

I scratched a bit of a long term itch and implemented basic support for the Performance Timeline specification for Node.js core. Hopefully it will land soon. There are still definitely some rough edges and certainly quite a few issues still to work out, but here’s how things work currently. Everything described below is subject to change.
Performance is a crucial part of our formula for a stellar user experience: just as a speedy search leads to happy users, so do performant web animations.
The average page is now 3MB in size, and this seems like a good time to pause, check our assumptions, and ask ourselves: Is there any reason to care about page size as a performance metric? And if we don’t consider page size a meaningful metric, then what should we care about?
Google and proponents of AMP would like you to think it is important because it is simply a faster way to deliver web pages. A lot of the thought behind AMP is that it will improve usability by delivering pages faster, which will keep users on your site longer. But is this actually a fact? AMP itself does not help with engaging users in a page. The content is what engages users.
The goal is to really understand Elixir to answer questions such as: What is it good at doing, In what way, Under what circumstances? What is it not good at doing, What are current pain points?, What are the tradeoffs?
Pinterest Search handles billions of queries every month and returns nearly four billion Pins every day. Over the past year, monthly mobile text searches have increased 40 percent and visual searches are up nearly 60 percent. We recently made Search and Lens more front and center on our apps by launching them on home feed, because nearly 85 percent of searches now happen on mobile devices.
Feature comparison tables are helpful not only in their primary function, though. When designed properly, they can aid in decision-making way beyond placing product specifications side by side. They can also add meaning to an otherwise too technical product specification sheet, explaining why a certain feature is relevant to the customer or how a certain product is better than the others.
A colleague of mine recently published an article on a new model that he coins the human environment model—an approach to product design that asks us to “blur the line between the digital and material environment,” and in doing so, generate an emotional appeal from our users. I thought I’d take a stab at exploring this concept as it relates to one experience in particular: browse. Designers have notoriously poured their blood, sweat and tears into browse experiences, and to what end? These experiences often overstimulate and under deliver.
In this world of intelligent auto-completion, why should we expect developers to remember and replicate matching class names across CSS and HTML? Modern frameworks are adapting to this shift and there are many different solutions to the problem of making styling and theming more intuitive. Here we will explore some of these solutions.
