Planning for 7.0

Posted Sep 12, 2017 by Henry Zhu

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.

Zero-config code transformation with babel-plugin-macros

Posted Sep 11, 2017 by Kent C. Dodds

Babel started out as a transpiler to let you write the latest version of the ECMAScript specification but ship to environments that don’t implement those features yet. But it has become much more than that. “Compilers are the New Frameworks” says Tom Dale and I could not agree more. We’re seeing more and more compile-time optimizations for libraries and frameworks. I’m not talking about syntax extensions to the language, but simple code transformations that enable patterns that would be difficult to accomplish otherwise.

Personal Experiences at Babel #1 — A PR with Unusually High Number of Reviews

Posted Aug 11, 2017 by Peeyush Kushwaha

We landed the parser support for the stage-2 decorators spec last week at Babylon — the parser for Babel. If you don’t know what a decorator is, the gist of it is that a decorator gives some concise syntax to affect the definition of a class or a class method which you decorate.

Posted Oct 31, 2015 by James Kyle

React on ES6+

Posted Jun 7, 2015 by Steven Luscher

While redesigning Instagram Web from the inside out this year, we enjoyed using a number of ES6+ features to write our React components. Allow me to highlight some of the ways that these new language features can change the way you write a React app, making it easier and more fun than ever.

Not Born to Die

Posted Feb 15, 2015 by James Kyle

I like to start off our blog posts with the latest big thing 6to5 has achieved. We haven’t reached it quite yet, but in a few days 6to5 and 6to5-core will have been downloaded half a million times, and in a month or so it will be over a million times.


Posted Jan 27, 2015 by James Kyle

These past few weeks we’ve seen lots of activity on 6to5; thousands are downloading it every day from all corners of the world. In the past month, over 200 issues have been closed. Since the 2.0 release, there have been 867 commits and 60 minor and patch releases. It’s now among the top 1% of most downloaded packages on npm, with nearly 100k downloads in the last month alone.

6to5 + esnext

Posted Jan 12, 2015 by James Kyle

The past few months have been exciting for 6to5. We’ve gone from being an educational project to having 100k downloads on npm, there’s been 1,800 commits and 155 releases, we now support every major JavaScript build system, and recently we became a Sprockets 4.0 default. To top it off, our new website and documentation received tens of thousands of pageviews, and has been featured by several publications including JavaScript Weekly.
