# 2.0.2
* #7 Fixed errors during rollup not rejecting the promise
* #9 Update dependencies
# Change Log
All notable changes to this project will be documented in this file.
# 2.0.1
* #5 Add logging on compile error & update to latest Rollup
The format is based on [Keep a Changelog](http://keepachangelog.com/)
and this project adheres to [Semantic Versioning](http://semver.org/)
# 2.0.0
**BREAKING** the options for the preprocessor are now specified in 2 separate object, `rollup` and `bundle`
## [3.0.0] - 2016-12-02
# 1.0.0
Initial version
A special thanks to [@klaascuvelier](https://github.com/klaascuvelier) who originally authored this repository, and has passed the torch to [@jlmakes](https://github.com/jlmakes) to keep things in tidy working order.
### Added
- Support for Karma `autoWatch: true`. Any file changes now properly reprocess all dependencies. [@brianmhunt](https://github.com/brianmhunt) [#3](https://github.com/jlmakes/karma-rollup-preprocessor/issues/3) [#11](https://github.com/jlmakes/karma-rollup-preprocessor/pull/11)
- Generated bundles are now cached for improved performance. [#10](https://github.com/jlmakes/karma-rollup-preprocessor/issues/10)
- Error log output has been improved for clarity.
### Changed
- **Breaking:** The `2.0.0` change that split preprocessor options has been reverted.
- Rollup dependency range changed to anything < `1.0.0`. [#12](https://github.com/jlmakes/karma-rollup-preprocessor/pull/12) [#13](https://github.com/jlmakes/karma-rollup-preprocessor/issues/13)
- Travis CI now tests in Node `0.12`, `4` and `6`.
- Updated `karma-jasmine` to latest major version.
### Removed
- Preprocessor no longer sets a default bundle format.
### Fixed
- Test script now uses explicit path to Karma binary.
## [2.0.2] - 2016-05-13
### Changed
- Rollup dependency version updated. [#9](https://github.com/jlmakes/karma-rollup-preprocessor/pull/9)
- Updated `karma-phantomjs-launcher` to latest major version. [#9](https://github.com/jlmakes/karma-rollup-preprocessor/pull/9)
- Replaced `phantomjs` with `phantomjs-prebuild`. [#9](https://github.com/jlmakes/karma-rollup-preprocessor/pull/9)
### Fixed
- Corrected typo preventing Rollup errors outputting to karma error log. [#7](https://github.com/jlmakes/karma-rollup-preprocessor/pull/7)
## [2.0.1] - 2016-01-11
### Added
- Rollup errors are now output to the karma error log. [#5](https://github.com/jlmakes/karma-rollup-preprocessor/pull/5)
- Rollup dependency version updated.
## [2.0.0] - 2015-12-14
### Changed
- **Breaking:** Preprocessor options have been split into 2 separate objects, `rollup` and `bundle`.

## Features
- Rebundles your files when watched dependencies change
- Caches bundle output for improved performance
- Maintained with ![heart](http://i.imgur.com/oXJmdtz.gif) by [@jlmakes](https://twitter.com/jlmakes)
This preprocessor is mainly used to bundle your spec entry point but might be useful in other cases as well.

# Configuration
The `rollupPreprocessor` configuration is optional. (You'll need to install more dependencies). It takes two keys: `rollup` and
`bundle`.
## Configuration
All the options detailed in the [Rollup Documentation](https://github.com/rollup/rollup/wiki/JavaScript-API) can be passed to `rollupPreprocessor`.
`rollup` is the configuration object for `rollup` (See [rollup.rollup](https://github.com/rollup/rollup/wiki/JavaScript-API#rolluprollup-options-) for more details).
### Example
Below is a well-founded recommendation using the [Bublé](https://buble.surge.sh) ES2015 transpiler:
`bundle` is the configuration object used when generating the bundle (See [bundle.generate](https://github.com/rollup/rollup/wiki/JavaScript-API#bundlegenerate-options-) for more details)
*Notice* this is preprocessor and does not write a file or return the bundle, only the content of the processed file gets changed.
So when adding the `sourceMaps` options, `inline` is the only logical value.
## Example
```js
// karma.conf.js
module.exports = function (config) {
config.set({
preprocessors: {
'test/main.js': ['rollup']
},
rollupPreprocessor: {
rollup: {
plugins: [
require('rollup-plugin-babel')({
presets: [
require('babel-preset-es2015-rollup')
]
})
]
},
bundle: {
sourceMap: 'inline'
}
}
});
config.set({
files: [
'src/**/*.js',
'test/**/*.spec.js',
],
preprocessors: {
'src/**/*.js': ['rollup'],
'test/**/*.spec.js': ['rollup'],
},
rollupPreprocessor: {
plugins: [
require('rollup-plugin-buble')(),
],
format: 'iife', // helps prevent naming collisions
moduleName: '<your_project>' // required for 'iife' format
sourceMap: 'inline', // sensible for testing
},
});
};
```
<br>
## Support
Supports all Rollup plug-ins, and works on Node `0.12.x` and up. Happy bundling!
