The general goal of remote procedure calls is to make distributed code look like local code to a developer. In web development, a developer often needs to write distributed code. This could be something as simple as a call-and-callback to a server. But, as more and more code moves from the backend to the frontend, distributed front end code could start to require libraries that support the complex, distrubted interactions that backend libraries currently do.
This project could also be useful to instructors, as the Typescript lanugage provides a much less verbose syntax than a language such as Java. This means the code required to build an RPC library could be more comprehensible to a student. This could be very useful to systems courses, which hope to expose students to many aspects of design, without getting stuck in the weeds of implementation.

Clone the package, then in the directory run
npm install // install basic dependencies
npm install --only=dev // install development dependencies
npm run jspm install // setup systemjs package loading
npm install -g typescript // install typescript compiler (if you haven't already)
tsc // compile typescript
npm start // start the serverThen naviage to localhost:8080
