QUESTION
I'm new to Scala :)
If I understand correctly, you have to first include the needed libraries in the Library Dependencies of the build.sbt
file before you can import the needed libraries into the scala script.
However, I have to do it in the other way around. I have to write a Python script to transform automatically Scala's import sentences into library dependencies sentences, in order to insert them into the build.sbt
file.
For example

In Scala, it is possible to import items at any location within the source code. This will complicate things. For example, in Spark code, you indirectly ask the Spark application master for what symbols it offers, which is stored in a variable passed back to you at runtime, and you import those.

I have a JSON that has a following structure (real world example is here https://gist.github.com/PavelPenkov/3432fe522e02aa3a8a597020d4ee7361):

QUESTION
I'm new to Scala and Scala.js and I want to experiment with handling JSON data. I'd like to simulate a server response by returning the content of a JSON file local to my Scala.js project, parse it and work with the data. What would be the best way to do so? Where should I place these files in my project tree, and how would I get their content?
Say that I have a file called myJSON.json
containing something like

Answered 2017-Nov-06 at 23:30Like others said above, Javascript that runs in the browser in general can't access the local filesystem. There are some exceptions:
The File API lets you access files that the user has selected in the UI using
or drag-and-dropped into the browser window.
The Filesystem API lets you access files the way you seem to want, but it is non-standard and is not supported in most browsers. It also seems that Scala.js has no typings for it, but I'm not sure.
scala-js-dom has typings for the File API that you can use – search for File
and FileList
types in its source. Its API mirrors the Javascript API, so you will need to look for how exactly to do this in JS. Then translating it into Scala.js will be easy (or at least a different question).
If the File API does not work for your use case, another option is to use something like json-server to easily serve your JSON files on localhost via HTTP.
