I actually tried to use @types/* directly but came across several issues which prevented me from switching over: - https://github.com/Microsoft/TypeScript/issues/8715 - https://github.com/Microsoft/TypeScript/issues/8723

/**
|
|
* Stabilizes the inputPath for the following plugins in the build tree.
|
|
*
|
|
* All broccoli plugins that inherit from `broccoli-writer` or `broccoli-filter` change their
|
|
* outputPath during each rebuild.
|
|
*
|
|
* This means that all following plugins in the build tree can't rely on their inputPath being
|
|
* immutable. This results in breakage of any plugin that is not expecting such behavior.
|
|
*
|
|
* For example all `DiffingBroccoliPlugin`s expect their inputPath to be stable.
|
|
*
|
|
* By inserting this plugin into the tree after any misbehaving plugin, we can stabilize the
|
|
* inputPath for the following plugin in the tree and correct the surprising behavior.
