A real-time voting system where users can create a poll and other users can cast their votes. The system generates a ranking among the options and updates the votes in real-time.
- Docker;
- Node.js;
- Clone the repository;
- Install dependencies (
npm install); - Setup PostgreSQL and Redis (
docker compose up -d); - Copy
.env.examplefile (cp .env.example .env); - Run application (
npm run dev); - Test it! (I personally recommend testing with Hoppscotch).
Create a new poll.
