In today's video I'll show you how to create a full stack voting app (a.k.a. poll system) with a frontend and backend.
We'll use HTML, CSS and JavaScript to build the client-side (frontend) and use Node.js and Express to build the server-side (backend).
Topics covered:
- Classes
- Async/Await Functions
- Event Listeners
- APIs
- GET and POST requests
- Form Data
- Reading and Writing JSON

decode strikes again with another GREAT IDEA🔥🔥, thanks bro for all of the beautiful useful content 👌🏽

[@oguznsari]

thanks dcode, minor advices for everyone:
1. we can fix the indentation issue when writing to the JSON file, by simply pretty-printing the parsed json like:
await fs.writeFile(dataFile, JSON.stringify(data, null, 2));
2. we can take 1 decimal only from a percentage like:
percentage: ((100 * votes) / totalVotes).toFixed(1) || 0.0

How are you my fellow web developer

[@marcoss4563]

there is a extension for vscode called Thunder client, its pretty for testing APIs. :)

Would be nice to see an advanced version of this same concept. Like one that prevents receiving votes from the same PC. It's the details that may bring some more value. On a poll system, a functionality one expect is some basic (or advanced) way to prevent a single user from submitting several votes.
Also been able to create polls would be cool too and that will add dynamic routing and a whole lot more.

Thank you a lot for the all videos, they are very useful!!!
By the way, the link on the Udemy course doesn't seem to be working… Could you share the correct link, please?

[@60secondsofcoding58]

I have noticed something that differs your videos from most of the other tutorials I follow, and that is that you always start with the back end where almost all other tutorials start with the front end and then switch to the back end when the front end is done.
How come that you prefer to it the other way around?
Just asking of pure curiousity.
Thanks for the great videos you deliver!

[@DailyNevFacts]

I have a friend who develops like this and his theory is getting functionality first then looks after! could be the same here.

[@mohammad-hosseinhashemian6804]

thhhhhhhhx a lot!
can anybody tell me what font it is

[@ChipyGamingVideos]

Hey dcode, great video! I was wondering if there was a way to make it so if you're viewing the poll, it will update every time anyone votes. For example, you have tab 1 and tab 2 both haven't voted. Tab 1 votes, the percentage is now 100 - 0 - 0. Then tab 2 votes, the percentage is now 50-50-0, but tab 1 still sees 100-0-0. I assume you refresh anytime the data changes?

[@FelicitationHumain]

Did you find any solution ? I have the exact same problem.

[@paladin9876]

@@FelicitationHumain you would need websockets to update it in live time (i wouldnt use this for a voting system anyways)
