A simple file-sharing service – the browser application

The client code of our new application is very similar to the previous application in some parts. Nevertheless, it will be significantly different in the core side, so we will rework it and discuss it in detail in this chapter.

The WebRTC API wrapper

We developed a wrapper for the WebRTC API in the previous chapter, so now it will be even easier to do the same for our new application. Now we will add some new code relevant to the Data API and for HTML5-specific API functions, which will be useful for file I/O operations, by performing the following steps:
