Question

I'm new to play framework and I'm trying to get it to work with RequireJs. When I run my app in dev mode everything runs fine, but when I set application.mode=prod and start the server with play start I'm running into problems.

The browser receives an HTTP404 when attempting to load /assets/javascripts-min/home/main.js.

Here's my Build.scala file

import sbt._
import Keys._
import play.Project._
import com.google.javascript.jscomp._
import java.io.File

object MyBuild extends Build {

  val appDependencies = Seq (
    jdbc,
    anorm,
    cache
  )

  val appVersion = "0.0.1"

  val appName = "TodoList"

  // set clojure compiler options so it won't choke on modern js frameworks
  val root = new java.io.File(".")
  val defaultOptions = new CompilerOptions()
  defaultOptions.closurePass = true
  defaultOptions.setProcessCommonJSModules(true)
  defaultOptions.setCommonJSModulePathPrefix(root.getCanonicalPath + "/app/assets/javascripts/")
  defaultOptions.setLanguageIn(CompilerOptions.LanguageMode.ECMASCRIPT5)

  CompilationLevel.WHITESPACE_ONLY.setOptionsForCompilationLevel(defaultOptions)

  val main = play.Project(appName, appVersion, appDependencies).settings(
        (Seq(requireJs += "home/main.js", requireJsShim := "home/main.js") ++ closureCompilerSettings(defaultOptions)): _*
    )
}
Was it helpful?

Solution

It turns out that I had a conflicting build.sbt (in the root directory) and Build.scala (in the project directory) files. Once I removed the sbt file, the requireJs optimization began working as expected
