Only import it in dev mode

[tcoopman]

What would your strategy be to only include this in development builds?

Something like doesn't work because import only works on toplevel.

if (NODE_ENV !== 'production') {
    import 'expose?Perf!react-addons-perf';
}

Do you mind using require instead?

if (NODE_ENV !== 'production') {
   require('expose?Perf!react-addons-perf');
}

@crysislinux Yeah, I know that works, I was mostly wondering if there is an alternative

@tcoopman import favors static analysis over flexibility and doesn't support dynamic imports.

IIUC, you should use System.import for this. See systemjs and es6-module-loader for more info, but I believe you could do something like:

if (NODE_ENV !== 'production') {
  System.import('react-addons-perf').then(Perf => window.Perf = Perf)
}

@jfsiii thanks!
