Building and running the site locally


  • Yarn

    This site is only tested and developed using yarn.


To run the site locally, first make sure you have all the dependencies installed:


Also make sure to install the dependencies in the lib directory.

cd lib
cd ..

Then run the following (from the top level directory) and answer all prompts:

yarn start:app:production

All prompts can be skipped, but certain demos rely on prompt answers to fully function. Notably, any demo that requries authentication will require you to put in a valid Google client ID.

This will set up a local hot-reloading instance of the app that can try out at http://localhost:5000


To run tests, first make sure you have all the dependencies installed:


Then run the following:

yarn test

Whats in this repo


This is where the majority of the client-side code lives. All of our demo code can be found here.


This file is useful to decorate our app with functionality that is needed at runtime.

Of note, we use:

  • wrapRootElement

    Lets us wrap the root element in any necessary context/providers. We use it for injecting a material-ui Theme provider, and a Redux store.

  • onInitialClientRender

    Any code that should run once after the client renders goes here.

    This code pulls in and configures gapi, a Google library that makes calling Google APIs from javascript a breeze.

Also see Gatsby browser APIs.


This is the main configuration file for our Gatsby site. All of our gatsby plugins are configured here.

  • gatsby-plugin-prefetch-google-fonts

    Allows us to download/prefetch Google Fonts. From their docs: "Can increase performance as opposed to loading webfonts from Google's external stylesheet."

  • gatsby-plugin-react-svg

    Makes it easy to load in SVGs as React components via the following stanza:

    import SVGComponentName from "-!svg-react-loader!../images/svg-name.svg"
  • gatsby-plugin-typescript

    Provides drop-in support for Typescript and TSX. <opinion>For a site like this, with demos that will live over many years, typescript is a handy way to make it easier to jump back in the code.</opinion>

  • gatsby-source-filesystem

    Lets us source data into the app that can be queried via graphql.
