Hi @onouguier-ledger,

The support for JSON output is missing in Twirl.

Twirl does not come with json support (myfile.scala.json) out of the box. Here are the formats that are supported ootb:

  def defaultFormats =
    Map(
      "html" -> "play.twirl.api.HtmlFormat",
      "txt"  -> "play.twirl.api.TxtFormat",
      "xml"  -> "play.twirl.api.XmlFormat",
      "js"   -> "play.twirl.api.JavaScriptFormat"
    )

You can however add custom formats, it's quite easy:

• Scala: https://www.playframework.com/documentation/3.0.x/ScalaCustomTemplateFormat
• Java: https://www.playframework.com/documentation/3.0.x/JavaCustomTemplateFormat

Can I to implement it as core feature ?

Why not? If you send a pull request to https://github.com/playframework/twirl I am happy to take a look. You can start by looking how xml format is implemented, it shouldn't be too hard. Just take care that escaping is handled correctly.

Thanks!
