v6.5.0

6.5.0 (2016-02-07)

Happy Superbowl Sunday! There's many contributors (17 + core) this release!

A traversal per preset (Experimental)

This is an experimental feature that will almost certainly change. You should use this option in specific cases while we figure out a better way to do this.
Depending on usage/feedback, we will switch the way this is used to instead define a explicit preset-level config flag (rather than the global one below). This will give more control over how you want to use this option.

{
  passPerPreset: true,
  presets: [
    {
      plugins: ['plugin-1']
    },
    'preset-2',
    {
      plugins: ['plugin-2']
    }
  ]
}
// this will create 3 traversals

Thanks to @​DmitrySoshnikov, passPerPreset: true will modify how babel traverses through plugins. Instead of a single traversal in which all plugins/presets are merged together, each preset will get their own traversal.

This allows users to have a specific order to how presets/plugins are applied and can help avoid potential collisions between plugins (and probably some known issues).

More Speeeeeeed

@​gzzhanghao made some awesome changes to improve our code generator's performance (babel-generator). The original issue is here.

Based on his test (on parsing jquery.js), performance improved ~3x.

===== origin/master (ms) =====
babylon 265
babel generator 2238 <-- old
acorn 107
escodegen 355
esprima 95
escodegen 322
===== Optimized (ms) =====
babylon 296
babel generator 662 <-- new
acorn 113
escodegen 355
esprima 106
escodegen 317

A big change had to do with keeping this.last as an instance variable in the buffer instead of this.buf[this.buf.length -1].

You can read more about his changes here. Hoping to see more PR's like this!

We will try to setup some perf tests soon to track these stats for the future (or you can help!).

New Feature
  • babel-core
  • babel-core
  • babel-helper-transform-fixture-test-runner, babel-plugin-transform-react-jsx-source
    • #​3285 Hoist the current file name (an absolute path) for transform-react-jsx-source . (@​frantic)

This plugin (useful for tooling) will turn

// this/file.js
<sometag />

into

var _jsxFileName = "this/file.js"; // the output will be an absolute path
var x = <sometag __source={{
  fileName: _jsxFileName,
  lineNumber: 1
}} />;
// analyse not analyze :D
// usage
babel.analyse("foobar;", {}, {
  Program: function (path) {
    path.mark("category", "foobar");
  }
}).marked[0].message // outputs "foobar"
  • babylon 
// allows for either `|` or `&`
type union =
 | {type: "A"}
 | {type: "B"}
;

This was added in flow in 7fb56ee9d8.
