Possible Gotchas

Here's a list of possible gotchas while coding against soggy, in @dbrain braindump format.

Zero value return from a route

If a route returns a zero value (or nil where applicable) it will not call a render function (unless it has an error, then it will call the error handler). This is to allow routes with a return to call Next without writing to the res again.

• func() string: If you return "" nothing will be rendered (vs. usual html)
• func() interface{}: If you return nil nothing will be rendered (vs. usual JSON)
• func() (string, interface{}): If you return "" for string (i.e. template name) nothing will be rendered.
