Server-Sent Events with Nuxt.js (Vue.js) and Nginx proxy

Suppose you have a Nuxt.js (Vue.js) application which calls a backend and which is behind a Nginx reverse proxy. If your backend stream Server-Sent Events (SSE) using text/event-stream content-type, you may have these errors: 504 (Gateway Time-out) or ERR_INCOMPLETE_CHUNKED_ENCODING (in Chrome).

Implementing a SOAP client with CXF using Play Framework 2.x

TL;DR: if you want to skip the tutorial, all code is directly available on GitHub: https://github.com/damienbeaufils/soap-client-with-cxf-using-play EDIT June 2016: code on my GitHub repository updated for Play Framework 2.5! Play 2.4 version is still available here. I was working on a new client product, and I had to plug a web application built with Play Framework (and then sbt) to SOAP web services. How to do it? The need: be able to generate Java classes from one or many WSDL files, and use those classes with Play 2.
