# 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.
