Windows 10 Development Environment for Scala

This is a guide for Scala and Java development on Windows, using Windows Subsystem for Linux, although a bunch of it is applicable to a VirtualBox / Vagrant / Docker subsystem environment. This is not complete, but is intended to be as step by step as possible.

I really liked @tjvantoll article Handling Failed HTTP Responses With fetch(). The one thing I found annoying with it, though, is that response.statusText always returns the generic error message associated with the error code. Most APIs, however, will generally return some kind of useful, more human friendly message in the body.

Here's a modification that will capture this message. The key is that rather than throwing an error, you just throw the response and then process it in the catch block to extract the message in the body:

fetch("/api/foo")
  .then( response => {
    if (!response.ok) { throw response }
    return response.json()  //we only get here if there is no error
 })

Introduction

I recently needed to apply CORS (Cross Origin Request Scripting) to a project that I'm working on. If found 2 posts that helped to achieve it:

I combined both to solve my problem: I have a User CRUD (Play!) webservice and a (Play!) web app that services a SPA (Single Page Application). The SPA needs to access the CRUD webservice, but to acheive this, I would need to apply some CORS rules on both applications.

Files

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	var FadeTransitionRegion = Backbone.Marionette.Region.extend({

	show: function(view){
	this.ensureEl();
	view.render();

	this.close(function() {
	if (this.currentView && this.currentView !== view) { return; }
	this.currentView = view;

	# Ubuntu upstart file at /etc/init/mongodb.conf

	pre-start script
	mkdir -p /var/lib/mongodb/
	mkdir -p /var/log/mongodb/
	end script

	start on runlevel [2345]
	stop on runlevel [06]

	group :test, :development do
	gem 'jasminerice'
	end
