This is a simple dashboard for crypto coins, showing top coins as well as liquidity graphing for coins.

This project called for some state management solution to store state outside of the two main components to allow the same data to be used on either page. I elected for useContext for this as it seemed like the correct size to handle this amount of data, while I thought something like redux would be too large, and prop drilling didnt seem appropriate to this use case.

I tried to set up my project in a design system way but ultimately as this project is just two pages with basically one component on them each I just went with a pages approach. The table and/or the chart could be separated into their own component and imported to the page, but i think this is better currently.

On the topic of charts. I searched forever to no avail until finally landing on plotly, which I think is the best (and maybe only) react chart library that would allow me to solve this task.

I elected to use mostly MUI where necessary for components to simplify the process.

I also realize there are some styling issues. My goal was to get it more or less okay, but with the chart specifically and the amount of time I have already spent on this task I thought it was better to leave some styling issues as a "would like to fix" for now.

For the api call i am using a reverse-proxy i set up on my heroku. It is just a simple repo I found.

I am also deploying the app with vercel: https://crypto-dash-teal.vercel.app/

Styling is the main thing currently that sticks out to me. The header is pretty basic and the page widths/heights are not always exactly correct.

I was also considering caching the api response to save my key from getting run too many times. Also this could help performance. So I would simply only call the fetch on the initial render and then I would save the full state in another context variable and pass back slices of it depending on the context value. I think this is could be a nice improvement (and not so complicated to implement), but I am out of time unfortunately!

Could add some more options for the table as well.

Should definitely add some testing as well.

This project was bootstrapped with Create React App.
