#What is Stock Picker?

Stock Picker is a free, open-source demo web app developed by Aryan Vichare, designed to showcase real-time stock price charting using Next.js and shadcn/ui’s charting library. Its primary goal is to provide a practical example of streaming server-rendered stock data, targeting React developers building financial dashboards or portfolio trackers. Built with Next.js, React Server Components (RSC), Tailwind CSS, TypeScript, and shadcn/ui, it fetches stock data from the Polygon.io API and visualizes it with shadcn/ui charts. Inspired by a tweet from @rauchg (Vercel CEO), the project leverages RSC for efficient server-side rendering and streaming, styled with Tailwind for a modern, responsive UI. For shadcn/ui enthusiasts, Stock Picker is a perfect fit, offering a lightweight, accessible charting solution with a Vercel-hosted demo.
