React Stock Market App - Looking for feedback :)


Recently finished the front-end framework certification, and I’ve been working on building a little portfolio. I’d love to hear what you guys think!

Here are the links:

It’s a React Project with node.js and Express on the server side. Making API calls from the back end is the only way I found to hide API keys. If there is a more efficient way to do it I’d love to hear about it. I’m using Chart.js for the charts.

It’s a portfolio project so I really want the code and design to be as clean as possible. Any critique is appreciated :smiley:

Thanks a lot in advance!
Happy hacking


Is it supposed to be showing $0?

Uhh… No. I swear it was working jus a minute ago :face_with_monocle:

Fixed it! I got to the limit of free api calls apparently. Switched back to sandbox mode so the data is not actual stock prices but it still works. Sorry about that :sweat_smile:

looks great !!!

the api, did you write it ? or it is an external api ?

Thanks! (Even tho it looks like the chart isn’t centered on your screenshot for some reason. I’ll have to give it a look)

I used an external API called Iexcloud. But I wrote my own little api with express that fetches data from Iexcloud and sends it to the front-end. This is to hide the Iexcloud api keys from the user :slight_smile:

it is center - just i copy a part of my screen so looked like it wasn’t

Looks good but it crashes if you put a * or + in the searchbar :rofl:

Also the first thing i do after creating a react app with create-an-app is change the favicon (there is an error for the size) and change the identity (check it with the devtools in chrome f12 > application tab)

Oh wow didn’t see that :flushed:
Good looks for the favicon and identity. I totally forgot about that ahah.
Thanks for the help! Much appreciated
