EventPub: Real Updates, Real Time, Real Simple

Inspiration

Analytics platforms should empower, not overwhelm. While Google Analytics and Firebase offer powerful insights, they often present a complex maze of data that requires significant expertise to navigate. We created EventPub with a different vision - one that puts user journeys and meaningful insights at the forefront.

EventPub emerges from a simple truth: understanding your users should feel as natural as having a conversation with them. Unlike traditional analytics that focus on aggregate numbers, we prioritize individual user stories and their complete journey through your product. Where Google Analytics gives you metrics, EventPub gives you meaningful user flows. Where Firebase shows you disconnected events, we show you coherent user narratives.

What it does

User Journey Visualization: Track and visualize individual user paths through your application in real-time
Customizable Dashboards: Create personalized views with drag-and-drop interfaces, inspired by Tableau's flexibility
Advanced Event Analytics: Transform raw events into meaningful insights with custom mathematical operations
Real-Time Monitoring: Watch user behavior unfold live with our WebSocket-powered interface
Team-Specific Views: Create dedicated dashboards for different teams and purposes
Custom Graph Creation: Build and customize graphs using mathematical operations to visualize data exactly how you need it
Intelligent Event Grouping: Automatically organize related events to tell a coherent story

How we built it

We architected EventPub with scalability and modularity in mind:

Frontend

React + Vite for a lightning-fast development experience
TypeScript for type safety and better developer experience
shadcn/ui for beautiful, accessible components
Custom visualization libraries for advanced graphing capabilities

Backend

Node.js and Express.js with TypeScript
Hexagonal Architecture for plugin-like extensibility
WebSocket for real-time communications
Redis for pub/sub and caching
MongoDB for flexible data storage
BullMQ for reliable event processing at scale
PassportJS for secure authentication

Challenges we ran into

Implementing complex mathematical operations for custom graph creation was particularly challenging
Designing a flexible yet intuitive dashboard creation system inspired by Tableau
Ensuring real-time data processing remains efficient at scale
Balancing between customization flexibility and user experience
Managing state across multiple real-time connections while maintaining performance

Accomplishments that we're proud of

Successfully implemented a fully customizable dashboard system that rivals professional analytics tools
Created an intuitive user journey visualization that makes user behavior instantly understandable
Built a scalable architecture that can handle millions of events while maintaining real-time capabilities
Developed a flexible mathematical operation system for custom graph creation
Achieved a perfect balance between power and simplicity in the user interface
