Planes, trains and automobiles

This project was bootstrapped with Create React App.

The Traffic Meister application assignment

Create a form which behaves as follows
- It will display the following drop down menus
  - A list of vehicle types
  - A list of vehicle brands
  - A list of vehicle brand colors
- All three lists are enabled when data is available.
- When selecting an option in on of the list, the other lists are filtered accordingly.
- At the bottom of the form all selections will be shown.
Use the framework based on the vacancy you're applying for. So if you applied to an Angular vacancy, use Angular. The same goes for React, VueJS, etc.
Except the framework restriction above, you are free to use any tool and/or framework you like. We do encourage you to remain critical when you include an additional dependency. Is this dependency really needed/useful? As long as it runs inside a browser and you can explain why that solution is the most favorable.
You are allowed/encouraged to design your own layout.
Your implementation should be
- tested
- visually attractive
- deployable

For example.

When yellow is selected all types and brands that have no yellow vehicles are filtered out
When selecting "Bugatti Veyron", only the car type and the available colors are selectable

Available Scripts

In the project directory, you can run:

`npm 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.

`npm test`

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

`npm run 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.

`npm run 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.

Data library

The data are provided by a small service you can find in the service folder.

This service can be accessed by a the global variable trafficMeister and provide a single method fetchData.

trafficMeister.fetchData(callBack);

The callback is called with the full data list as first parameter.

trafficMeister.fetchData(function(err, data) {
  console.log(data);
});

The data library can be used as a node module.

var trafficMeister = require('traffic-meister');
trafficMeister.fetchData(function(err, data) {
  console.log(data);
});

Coding Assignment Evaluation Guidelines

To give you an idea what we expect from the implementation of the assignment we came up with the following guidelines. In general, treat it as code that will go in production for one of our clients.

Important! We will provide you with a Github repository where you can create your assignment in. As soon as you create a pull request to master our bot will immediately lock you out of the repository and the assignment is over. So before you put in a pull request, make sure you are done!

Assignment

Does the code work.
Does the code still work when encountering edge cases.
Does the code come with instructions.
Do all included artifacts have purpose.

Code quality

Is the code structured in a logical way.
Could the code be extended.

Does the code show software engineering best practices and design patterns where applicable.
Is the code consistent.
Does the code contain descriptive names.
Is the code production ready.
Does the code base scale to a bigger feature set.

Frameworks + Language

What framework was chosen.
Are the features of the framework used according to community best practices.
Does the code use features of the framework or language when possible.
Are common pitfalls avoided.

Testing

Are there automated test.
How are the tests written.
What choices are made in testing certain parts of the code.
Are the tests written with the right level of abstraction.
What test cases are chosen.
