Decorators are not officially supported yet in 6.x pending a proposal update.

I am still getting

Module build failed: SyntaxError: Decorators are not officially supported yet in 6.x pending a proposal update.
However, if you need to use them you can install the legacy decorators transform with:

npm install babel-plugin-transform-decorators-legacy --save-dev

and add the following line to your .babelrc file:

{
  "plugins": ["transform-decorators-legacy"]
}

even after npm install babel-plugin-transform-decorators-legacy --save-dev and updating .babelrc any thoughts?

{ "presets": ["react", "es2015", "stage-1"], "plugins": [ "transform-decorators-legacy", "transform-class-properties" ] }

Forgot to add plugins to webppack.config works fine now
