How to load JSON file using Play with Scala
Looks like the comment about the possible duplicate is how to read a file from your app/assets folder. My answer is about how to parse Json from a stream. Combine the two and you should be good to go.
Json.parse accepts a few different argument types, one of which is InputStream.
val stream = new FileInputStream(file)val json = try { Json.parse(stream) } finally { stream.close() }P.S. When you can't find what you're looking for in the written docs, the API Docs are a good place to start.
Here is how I managed to solve it:
val source: String = Source.fromFile("app/assets/jsons/countriesToCities.json").getLines.mkStringval json: JsValue = Json.parse(source)Thanks for the help! :)
From Play 2.6, Environment has the getExistingFile, getFile, resource and resourceAsStream methods, E.g.:
class Something @Inject (environment: play.api.Environment) { // ... environment.resourceAsStream("data.json") map ( Json.parse(_) )(Note, in this case data.json is inside the conf folder)
