React Zipcode Task

Create an application to collect a user’s name, address and zipcode.

Implementation instructions

• Use modern front-end technologies (Feel free to use the react-app starting point)
• Use zipcodes.json to validate the provided zip-code
• Provide a minimal README containing your approach and running instructions
• Write meaningful tests that prove your solution
• Provide meaningful commit-messages
• Keep external libraries to an absolute minimum (we prefer a homebrew solution that is not 100% feature-par with a out-of-the-box third-party-solution to see your skills)

Minimum requirements

• Input fields for name, address, city and zipcode
• Validation that name and address are not empty
• Validation that the provided zipcode is valid and located in germany
• Submit-Button

Optional features

• Create a modern and easy-to-use GUI
• Autocompletion for city-names while the user is typing
• Submit-button is only clickable if inputs are valid
