This change primarily exists to import Typescript and the ES6 module loader polyfill as dependencies for this project. Both dependencies are relatively lightweight and can be easily removed if we decide we don't need them. The module loader polyfill implements support for an upcoming browser feature in ES6 (the next version of JavaScript). This feature helps modularize Javascript code and conveniently split it into multiple files. It should be supported by the stable versions of the four major browsers (Chrome, Firefox, Safari and Edge) by the end of the year. Once that happens, we can remove the polyfill. The Typescript compiler provides two things: First, it compiles new, but not-yet-supported ES6 Javascript features into ES5. It also provides a typechecker similar to what Closure does, but types are indicated in syntax rather than JSDoc comments. If we decide we don't want this dependency, we can compile the Typescript code into human-readable JavaScript code. (The compiler basically strips out types and replaces ES6 language features with more well-supported JavaScript equivalents). The Typescript compiler is not required for development. typescript.js and a feature in the module loader will be used to compile Typescript into JavaScript at serving time. (We might want to do something different for the production version, but we can get to that later). The change also adds code to serve the HTML and Javascript files.

Go Heap Viewer Client
This directory contains the client Typescript code for the Go heap viewer.
Typescript Tooling
Below are instructions for downloading tooling and files to help make the development process more convenient. These tools are not required for contributing or running the heap viewer- they are just meant as development aids.
Node and NPM
We use npm to manage the dependencies for these tools. There are a couple of ways of installing npm on your system, but we recommend using nvm.
Run the following command to install nvm:
[shell]$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/install.sh | bash
or see the instructions on the nvm github page for alternative methods. This will put the nvm tool in your home directory and edit your path to add nvm, node and other tools you install using them. Once nvm is installed, use
[shell]$ nvm install node
then
[shell]$ nvm use node
to install node.js.
Once node is installed, you can install typescript using
[shell]$ npm install -g typescript
Finally, import type definitions into this project by running
[shell]$ npm install
in this directory. They will be imported into the node_packages directory and be automatically available to the Typescript compiler.
