What does successfully setting up the coding environment look like?

[maptastik]

I am working on setting up my environment for the Vis Academy using Windows 10. While the instructions have mostly been clear, I have been tripped up on the very last portion of Installing a coding environment > Downloading code examples, Specifically, Verifying that everything works.

I believe that I was able to successfully able to load all the packages by doing the following:

cd vis-academy/src/demos/building-a-geospatial-app/starting-code
npm install

When I run npm run start I get the following output:

> building-a-geospatial-app@0.0.1 start C:\Users\maptastik\Documents\LEARNING\vis-academy\src\demos\building-a-geospatial-app\starting-code
> webpack-dev-server --config ./webpack.config.js --mode development

While the instructions from the Vis Academy state to open up http://localhost:3030 in my browser, it appears that the server is actually running at http://localhost:8080. It looks like this mismatch in ports will be resolved by #81. Alas, I navigated to http://localhost:8080 in my browser. Here is what I see:

I am certain this will seem an obtuse questions, but is this what success looks like when setting up the environment?

The instructions state (emphasis mine):

We are going to build the app from the first lesson, "Building a Geospatial App", to make sure that everything works.

However, what shows up in my browser is this indicator that my Mapbox token is set. Is that what "everything" is? I'm a little confused because I thought we checked out Mapbox token in the section Installing a coding environment > Installing Tools - Windows.
