Simple react app to use as basis to talk about code in interviews

Some topics to talk about

Run through / lifecycle

• A bit theoretical: What's the lifecycle of this react app?
• How would you test the app?

Tasks

• Show the myShip GeoJSON on the map!
• Fix the app so that the map shows the area where the GeoJSON line is being drawn on startup.
• Extract the GeoJSON line to a separate file and load it and display it once the map is rendered.
• Using a publicly available web endpoint that serves GeoJSON, implement the loading and rendering of GeoJSON loaded over the internet.

Some sources of public GeoJSON serving APIs:

This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

yarn build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
