-# 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](github.com/creationix/nvm)
-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.
