trait JSApp extends AnyRef

Base class for top-level, entry point main objects (softly deprecated).

In Scala.js 1.x, js.JSApp will disappear. It is currently "softly" deprecated: it is not recommended to use it in new code, but it does not cause a deprecation warning (yet). Prefer using a standard main method (see below).

Objects inheriting from JSApp are automatically exported to JavaScript under their fully qualified name, and their main method as well.

JSApp is typically used to mark the entry point of a Scala.js application. As such, the sbt plugin also recognizes top-level objects extending JSApp. It allows to run their main method with sbt run, and can also generate a tiny JavaScript launcher snippet executing the main method of one specific JSApp object.

Starting with Scala.js 0.6.18, the sbt plugin can also recognize "standard" main methods of the form

def main(args: Array[String]): Unit = ...

in objects, even if they do not extend JSApp. Such main methods are cross-platform, and should be preferred over extending JSApp in new code. Note however that:
