Getting rid of node_modules

The Yarn team is brewing up a new way to resolve dependencies: this RFC a new alternative and entirely optional way to resolve dependencies installed on the disk, in order to solve issues caused by the incomplete knowledge Node has regarding the dependency tree. We also detail the actual implementation we went with, describing the rational behind the design choice we made. Pretty exciting if/when they pull it off. The wins: Installs ran using Plug'n'Play are up to 70% faster than regular ones (sample app) Starting from this PR, Yarn will now be on the path to make yarn install a no-op on CI Yarn will now be able to tell you precisely when you forgot to list packages in your dependencies Your applications will boot faster through a hybrid approach of static resolutions

You probably don't need Moment.js

When you pull in a library dependency, it is rare that you need all of the functionality it offers. This isn't usually a problem for backends, because that code never leaves the server. However, In frontend-land your users pay the price for all that unused functionality every time they hit your website with a cold cache. Moment.js is an excellent date/time library. It is packed with functionality, and you probably don't need everything it has to offer. Instead, check out date-fns, which offers small, highly targeted functions you can probably get by with. There's even an ESLint plugin that will help you identify places in your codebase where you don't really need Moment.js!

Babel 7 released

After almost 2 years, 4k commits, over 50 pre-releases, and a lot of help we are excited to announce the release of Babel 7. It's been almost 3 years since the release of Babel 6! There's a lot of moving parts so please bear with us in the first weeks of release. Babel's role in the JavaScript ecosystem... Babel is fundamental to JavaScript development today. There are currently over 1.3 million dependent repos on GitHub, 17 million downloads on npm per month, and hundreds of users including many major frameworks (React, Vue, Ember, Polymer), and companies (Facebook, Netflix, Airbnb). It has become such a foundation for JavaScript development that many people don't even know that it is being used. Even if you aren't using it yourself, it's highly likely your dependencies are using Babel.

Vue CLI 3.0 is here!

Good news — the next generation of Vue CLI, the standard build toolchain for Vue applications, is here. Evan You writes: Vue CLI 3 is a completely different beast from its previous version. The goal of the rewrite is two-fold: Reduce configuration fatigue of modern frontend tooling, especially when mixing multiple tools together; Incorporate best practices in the toolchain as much as possible so it becomes the default for any Vue app. This means that any Vue CLI 3 project comes with out-of-the-box support most of today's preferred ways to build and ship applications.

How far can JavaScript take us?

Tanner Villarete asked himself, "How far can JavaScript take us?" Then answered: Turns out, pretty dang far. This web app was my attempt at mimicking Apple's iOS music app, and I think I've come pretty close! I have to admit, he did a pretty good job. The frontend is built on React and Redux. The backend? A Laravel-based API running on a Raspberry Pi! Here's the live demo, but be nice because Raspberry Pi.
