Modern Modules - Re-thinking the Node.js ecosystem for modern JavaScript
We need to rebuild most of the software infrastructure in the Node.js Ecosystem. In order to move forward we’re going to have to stop using a lot of the software infrastructure we rely on today but first we need solid alternatives. I’ve started to take this on, as time allows. I’ve already mentioned r2. I’ve also written an async/await bi-directional RPC library called znode.

How JavaScript works: memory management + how to handle 4 common memory leaks
We’ll discuss another critical topic that’s getting ever more neglected by developers due to the increasing maturity and complexity of programming languages that are being used on a daily basis — memory management. We’ll also provide a few tips on how to handle memory leaks in JavaScript that we at SessionStack follow as we need to make sure SessionStack causes no memory leaks or doesn’t increase the memory consumption of the web app in which we are integrated.

Understanding & Measuring HTTP Timings with Node.js
Understanding and measuring HTTP timings helps us to discover performance bottlenecks in client to server or server to server communication. This article explains timings in an HTTP request and shows how to measure them in Node.js.

What I Love and Hate About Flow
The Good: Eliminate a whole class of errors; Easier refactoring; Helps document things. The Bad: A false sense of security from the misconception that this will have any effect at runtime, More damn errors to fix before your pull request gets merged in, It’s a big time investment. The Verdict: Use Flow (or Typescript) but don’t half-ass it. Go all out and require it in all files. 另附来自 tumblr 的实践: Flow and TypeScript

I don’t know who the Web Audio API is designed for
Web Audio, conversely, is an API I do not understand. The scope of Web Audio is hopelessly huge, with features I can’t imagine anybody using, core abstractions that are hopelessly expensive, and basic functionality basically missing. To quote the specification itself: “It is a goal of this specification to include the capabilities found in modern game audio engines as well as some of the mixing, processing, and filtering tasks that are found in modern desktop audio production applications.” I can’t imagine any game engine or music production app that would want to use any of the advanced features of Web Audio. 附:Some Opinions On The History Of Web Audio

CSS in JS is like replacing a broken screwdriver with your favorite hammer
You’ll get the screw further into the wall, but you also destroy all of the unique and valuable problems that had you using a screw instead of a nail in the first place!

Building the DOM faster: speculative parsing, async, defer and preload
The fresh web standard <link rel="preload">, that allows you to load critical resources faster, is coming to Firefox later this month. Understanding what goes on inside a browser is the most powerful tool for every web developer. We’ll look at how browsers interpret your code and how they help you load pages faster with speculative parsing. We’ll break down how defer and async work and how you can leverage the new keyword preload.

In this blog, we’ll first review how we went about building out this backbone network and then discuss the benefits that it’s delivering for us and for our users.

A Brief, Incomplete History of JavaScript
In 2017, JavaScript development can leave newcomers to the language—and many veterans—paralyzed, unsure of where to begin or which paths are the right ones to take. People often dive into the latest-and-greatest without any real understanding of why it’s so great (or why it might not be). Understanding JavaScript’s history can help make sense of its current state.

What every software engineer should know about search
Numerous current products still have suboptimal search experiences. Any true search expert will tell you that few engineers have a very deep understanding of how search engines work, knowledge that’s often needed to improve search quality.

Why is Python Growing So Quickly?
Why is Python growing so fast? Python is used in a variety of purposes, ranging from web development to data science to DevOps, and it’s worth understanding what particular applications of Python have recently become more common. I’m a data scientist who uses R, so I’m certainly interested in how much of Python’s growth has been within my own field. In this post, I’ll take another look at Stack Overflow data to understand what kinds of Python development have been growing, and in what kinds of companies and organizations it’s most used.

Design Tooling is Still Figuring Itself Out
At the moment, there are all kinds of things that design software is struggling to address. The term “screen design” is common, referring to the fact that many of us are designing very specifically for screens, not print or any other application and screens have challenges unique to them. We have different workflows these days than in the past. We have different collaboration needs. We have different technological and economic needs.

Introducing Microsoft’s Fluent Design System
It should be noted that the Fluent Design System is in active development, so some of the design principles and features may change as the design language progresses. Always make sure to check the official documentation for up-to-date information.

Babel - Planning for 7.0
If you didn’t know already, we’re planning on releasing a 7.0 version soon 🙌 ! Work on it actually started back in February, when I just wanted to make a release to drop Node 0.10/0.12 support and remove babel-runtime and various other code. And since then, we’ve done releases up to alpha.20.

Messenger.com is the web version of Facebook Messenger; we also share code with facebook.com’s inbox view and chat tabs. For over a year, the Reason team has been working directly on Messenger in order to integrate Reason + BuckleScript into the codebases. As of a while ago, we’ve reached 50% Reason code coverage!

On React and WordPress
WordPress is to undergo a full rewrite of its ‘Gutenberg’ editor, moving away from using React due to patent ‘baggage’. We’ll look for something with most of the benefits of React, but without the baggage of a patents clause that’s confusing and threatening to many people. Thank you to everyone who took time to share their thoughts and give feedback on these issues thus far — we’re always listening. 另附:如何看待百度要求内部全面停止使用 React/React Native

Unified autoplay
Starting in Chrome 64, autoplay will be allowed when either the media won’t play sound, or the user has indicated an interest in the media. This will allow autoplay to occur when users want media to play, and respect users’ wishes when they don’t.

7 Helpful HTTP Tools
We’re going to look at some of these tools, and briefly summarize what they do. We’ll look at a variety of implementations, both command-line and GUI-centric HTTP clients, and talk generally about what they do, and how an API provider might find value in them. To be clear, we’re not recommending a specific tool here, as finding the right tool will be highly variable for each provider.
