karma-buble-preprocessor

A Karma preprocessor for the Bublé ES2015+ compiler.

Maintenance status

As Bublé is no longer under active development, there is no plan to add new features to this module. However critical security issues may be fixed.

Installation

To install as a devDependency:

npm install --save-dev karma-buble-preprocessor

Configuration

Just add it to the preprocessors section of your Karma configuration file, for instance:

// karma.conf.js
module.exports = function (config) {
  config.set({
    preprocessors: {
      'test/**/*.js': ['buble']
    }
  })
}

Purpose

This preprocessor uses Bublé to transpile JavaScript ES2015+ into ES5 suitable for older runtimes.

Bublé will not handle import statements in the code, so consider using a packager such as karma-rollup-preprocessor instead.
The result of the transpilation is not saved, so for implementation code, consider using buble-loader in webpack, or rollup-plugin-buble in rollup, so that the tests are run on what is shipped.
