Let’s Dev: A Package Manager
Hello everyone! Today, we’re gonna write a new package manager, even better than Yarn! Ok, maybe not, but at least we’re gonna have some fun, learn how package managers work, and think about what could come next on Yarn.

ES8 was Released and here are its Main New Features
EcmaScript 8 or EcmaScript 2017 was officially released at the end of June by TC39. It seems that we are talking a lot about EcmaScript in the last year. It’s not for nothing. Currently the standard is to publish a new ES specification version once a year. ES6 was published in 2015 and ES7 was published in 2016, but did someone remembered when ES5 was released? It happened in 2009, before the magical rise of JavaScript. 另附:Pattern Matching in ECMAScript

Security updates for all active release lines
Updates are now available for all active Node.js release lines as well as the 7.x line. These include the fix for the high severity vulnerability identified in the initial announcement, one additional lower priority Node.js vulnerability in the 4.x release line, as well as some lower priority fixes for Node.js dependencies across the current release lines.

Introducing npx: an npm package runner
npx is a tool intended to help round out the experience of using packages from the npm registry — the same way npm makes it super easy to install and manage dependencies hosted on the registry, npx makes it easy to use CLI tools and other executables hosted on the registry. 另:npm v5.3.0

Upcoming RegExp Features
ES2015 introduced many new features to the JavaScript language, including significant improvements to the regular expression syntax with the Unicode (/u) and sticky (/y) flags. In this blog post we want to give you a preview of this exciting future. If you’d like to follow along with the upcoming examples, enable experimental JavaScript features at chrome://flags/#enable-javascript-harmony.

Introducing sphinx-js, a better way to document large JavaScript projects
sphinx-js consumes standard JSDoc comments and tags—you don’t have to do anything weird to your source code. You just have Sphinx initialize a docs folder in the root of your project, activate sphinx-js as a plugin, and then write docs to your heart’s content using simple reStructuredText. When it comes time to call in some extracted documentation, you use one of sphinx-js’s special directives, modeled after the Python-centric autodoc’s mature example.

The MVC Design Pattern in Vanilla JavaScript
The MVC pattern is good for client-side frameworks, but modern frameworks change. What is modern today is subject to the passing of time and withers away. In this take, I’d like to explore alternatives and see where a little discipline takes us.

Event Delegation: Pattern or Anti-Pattern
Event delegation is one of the defacto ways of doing event handling. But is it the right methodology for all projects? In fact, the better question might be whether the assumptions each toolkit has made are right for your project. Knowing whether an API is right for your project depends on knowing what assumptions these tools are built on and understanding how each toolkit has interpreted them.

Developer Experience Lessons Operating a Serverless-like Platform At Netflix
This is the first in a series of posts where we draw from our learnings to outline various aspects that we are addressing in the next generation of our platform. We believe these aspects are applicable to general purpose serverless solutions too. Here we will look at application development, delivery and code composition. Future posts will delve into topics such as deployments, insights, performance, scalability and other operational concerns.

What 10 Things Should a Serious Javascript Developer Know Right Now
Scope, Architecture, DOM, Node.js…

How Rust is tested
I’ve always admired well-tested software projects, like SQLite, and aim to place Rust among the pantheon of the best. This document then, is a catalog of all the ways we test Rust. I hope it provides insight into what it takes to deliver a production-quality programming language, a hint at the wide variety of techniques employed in software validation, and that it reinforces your confidence in Rust’s reliability. 另附:Principles of Automated Testing

Mock system APIs
When you write your module (let’s say a Node JavaScript one), you often expose public API, but internally your code accesses the outside world via own code. Testing the public API is the best, but often it is hard, since your code interacts with the file system, user or network. How do you test the exposed API when you need to mock the rest of the system? I think it is preferable to NOT mock your own code modules, but to mock the interface to the external world.

Don’t write an SPA* Unless it makes sense to
SPAs are a good choice if: The interface you’re building is highly interactive and needs to be fast / responsive — and you want an architecture and abstractions that supports this out the gate; You’re not worried about each and every bit of content being indexed by search engines correctly. On the other hand, an SPA might not be worth the complexity if: Your application is simple (there’s not a lot of interactive content); SEO is of pivotal importance.

What is “modern” programming
I submit to you that modern programming has little to do with the look of your desktop. Graphical user interfaces are only skin deep. Modern programming techniques are all about processes and actual tools, not the skin on top of them. I don’t care whether you are using Eclipse or Emacs… this tells me nothing about how modern you are. So what is “modern”?

A Complete List Of UX Deliverables
The list below contains most common deliverables produced by UX Designers as they craft great experiences for users. For better readability, I’ve combined the deliverables according to UX activities: User Research, Market Research, Design, Testing. For each item in the list you’ll find additional links or video with detailed explanation or best practices.

URLs are UI
So many folks spend time on their CSS and their UX/UI but still come up with URLs that are at best, comically long, and at worst, user hostile.

Building open source tools for Adobe Creative Cloud updates
Our Enterprise Engineering team recently developed a software management script that could save teams hundreds of hours in building application packages for Mac users. The new system makes it easier for people to access Adobe apps with centrally-managed Creative Cloud licensing, while saving time and improving reporting and accounting accuracy.

emotion - The Next Generation of CSS-in-JS
emotion is a high performance, lightweight css-in-js library. The core idea comes from Sunil Pai’s glam library and its philosophy is laid out here. The basic idea is simple. You shouldn’t have to sacrifice runtime performance for good developer experience when writing CSS. emotion minimizes the runtime cost of css-in-js dramatically by parsing your styles with PostCSS during compilation instead of at runtime. 详见介绍文

gpu.js is a single-file JavaScript library for GPGPU (General purpose computing on GPUs) in the browser. gpu.js will automatically compile specially written JavaScript functions into shader language and run them on the GPU using the WebGL API. In case WebGL is not available, the functions will still run in regular JavaScript.

Redis 4.0 GA is out!
Redis 4.0.0 is out. I’m very happy about 4.0, because this release finally overcomes several very important limits of Redis. There are many things in the 4.2 plan, so Redis with 4.0 is not magically perfect. Yet it is a very important, measurable, step forward, because of the following features.
