The goal is to create a small React application that uses the Wolfram Alpha API ( https://products.wolframalpha.com/api/documentation/ ) to display the path of the sun and the moon for six different cities.
It should take you around 2-3 hours to complete. (This estimation assumes you have worked with create-react-app
and basic bootstrap grids recently, so if you need to learn / refresh about these tools it will add to the time needed to complete this exercise).
You can look at the expected view for the moon in Berlin here : https://github.com/HendrikW/IH-coding-challenge-march/blob/master/screen_recording_moon.mov?raw=true .. sun path and other cities should work accordingly :-)
- it should use Bootstrap and look decent on a mobile device ( don't spend too much time on styling details, just don't force mobile users to pinch-zoom please ;) )
- there should be two different pages/views
- one that shows the path of the moon (as an image) for each city in a separate box
- another page that shows the path of the sun (as an image) for each city in a separate box
- it should have a detailed README that allows a step-by-step setup of the application on the interviewer's laptop.
- you can choose any six cities that you like.
- any search query you can do via WolframAlpha you can also do via their API. ( e.g. https://www.wolframalpha.com/input/?i=sun+berlin and https://www.wolframalpha.com/input/?i=moon+berlin )
- you can sign up via http://developer.wolframalpha.com/ -> it's free, just type in a name/email and a description for your app etc. (e.g. "testing").
- you should use the JSON variant of the API (
output=json
) - it's going to be a completely public page, so no user/login required.
- if you want to use the API from the frontend (this is not really supported by WolframAlpha, but makes sense to complete the project without having to write a backend first): use
open -n -a Google\ Chrome --args --disable-web-security --user-data-dir=/tmp/chrome
to open an instance of Chrome that does not care about CORS. WINDOWS-users see here: https://alfilatov.com/posts/run-chrome-without-cors/ . DON'T use this for your average web browsing, please, only for this exercise ;-)
- allow the user to add more cities.
- store the cities the user added into a session (so when they close the page and open it later again, the added cities are still there, unless they clear their browser cache)
