velofolio's Introduction

velofolio

velofolio is yet another U.S. Stock backtest simulator tool. You can easily share your backtest or explore other's backtest within service. This service is currently in beta stage.

This project is a monorepo of the velofolio service. It contains client & server projects.

This web project is deployed via Vercel.

velofolio's Issues

Comment system

Let others comment on the backtest!
But I am concerned that there might be spammers..
Perhaps implementing reporting system might be the solution. However, if there aren't enough users, this system will not work.

Allow decimals in weight

URL is not valid

Associated links to the site redirect to spam sites

Portfolio remove not applied to report

idk why

Implement SSR

Implement SSR for better search indexing.
May be the google searchbot it crawl the page properly without SSR.

However, I believe SSR should be done for better SEO results.

This task might be complicated since I am using echart.
My plan is to show image chart generated from server temporarily. Then, show the proper chart after some kind of weird process of hydration.

Mobile responsive design

Before releasing this project to public (like reddit or twitter), I think I should implement a minimum responsive design for the project.

Can't make it working

I am a new bee to node.js and studying web dev.

I forked this project and ran server and app.

but I got this error msg when I make an auth via. Google.
