Caching option does not work

[binarykitchen]

It seems that setting cache to true has no impact on webpack's gulp plugin.

Does it work directly with webpack?

[binarykitchen]

No idea, documentation does not say much.

You should probably make sure that is working first. Since this plugin doesn't do any caching, just interfaces with webpack itself, it's likely not an issue here. For general questions on how webpack works, try their https://gitter.im/webpack/webpack channel or stackoverflow. If you figure it out please add it to webpack's docs, they are freely editable.

This is actually an issue with the plugin, as it is creating a new instance of webpack on every run, as far as I can tell.

@shama — that'd be great if we could pass an instance of webpack to the plugin rather than webpack itself.

const compiler = webpack(webpackConfig)
...
.pipe(webpackStream(compiler, cb))

For caching to work, we have to use the same instance on subsequent compiles.

Update I've made a PR, #109, that fixes this by caching webpack internally. No API change was necessary.
