I keep having the need to provide custom javascript with a GopherJS library. For something like AngularJS, it seems fair to ask a user to include the library manually, but with custom library code it becomes a chore.

I created a utility to get around this https://github.com/ajhager/shmi, but it adds a manual build step. I wonder if it would be helpful to provide a mechanism to bundle javascript automatically using GopherJS.

There are a few ways this could be handled, but I suggest perhaps:

import "github.com/gopherjs/gopherjs/js"

js.Provide("./myjscode.js")
// OR
js.Import("./myjscode.js")
// OR
js.Bundle("./myjscode.js")

The compiler could make sure any javascript files would only be bundled once, and raise an error if the files don't exist.

I am happy to work on this, but I would appreciate some feedback.
