@ava/babel-preset-stage-4
Babel preset for use with AVA
Aspires to bring ECMAScript stage 4 proposals to AVA's test and helper files.
Efficiently applies the minimum of transforms to run stage 4 code on Node.js 4, 6 and 8.
Built-ins are not added or extended, so features like Proxies, Array.prototype.includes
or String.prototype.padStart
will only be available if the Node.js version running the tests supports it. Consult node.green for details.
Sometimes a particular feature is mostly implemented in Node.js. In that case transforms are not applied. This applies to new.target
and iterator closing, which are not supported in Node.js 4 even though classes and iterators are.
Install
$ npm install --save @ava/babel-preset-stage-4
Usage
Add @ava/stage-4
to your Babel presets.
Require @ava/babel-preset-stage-4/package-hash
