This is a stock watchlist app using the following tech stack:
Front-end: Angular (v.16)
Backend: Node.js (v.18), Express Framework in TypeScript
Databases: MySQL, and MongoDB
Caching: Redis
- This app supports users log in and log out, and provides a single screen with a search bar, and a list of stocks with their current prices.
- It contains both a stock watchlist service and a client application that allow users to view their favorite stock prices.
- Users are able to search for stocks by name or ticker and add them to a watchlist.
- Users are able to remove a stock from their watchlist.
- Users are able to see the current price of the stocks in their watchlist.
- During the market trading hours, users can see the prices update every 5 seconds.
- The backend service is designed to support millions of users each with their own watchlist.
- A user's favorite stocks are persisted into DB and will be loaded from DB when this users logs in again to the app.
- You can review the service architecture and communication between the service and client application; client-code is stored in the client/ directory and the server side code is stored in the server/ directory.
- The server side uses Redis to cache data so it limits the number of times to hit the 3rd party APIs for the company list and stock prices.
