Challenges we ran into
๐ง Challenges I Ran Into
1๏ธโฃ Google Maps API Billing Crisis ๐ณ
The Problem:
Google Maps API required credit card verification and billing setup, even for the free tier. This was a blocker for a student project.
The Solution:
Migrated to OpenStreetMap + Leaflet - completely free, open-source, and no billing required. Bonus: better aligned with our accessibility mission.
2๏ธโฃ React-Leaflet Version Incompatibility ๐ฅ
The Problem:
After switching to Leaflet, the Add Item page showed blank. Error: render2 is not a function. React-Leaflet v5 expected React 19, but we used React 18.
The Solution:
Downgraded to compatible versions:
bash
npm install [email protected] [email protected] --legacy-peer-deps
Moved Leaflet CSS to main.jsx for global scope.
3๏ธโฃ Vercel Deployment Build Failures ๐
The Problem:
Build worked locally but failed on Vercel with path resolution errors:
Error: Rollup failed to resolve import "/src/main.jsx"
The Solution:
Deployed pre-built dist folder instead of letting Vercel build from source. Built locally, deployed the compiled output via Vercel CLI.
4๏ธโฃ Firebase Real-time Chat Sync ๐ฌ
The Problem:
Messages not appearing in real-time, duplicate messages, inconsistent ordering.
The Solution:
Implemented proper real-time listeners with onSnapshot() and cleanup:
javascript
const unsubscribe = onSnapshot(
query(messagesRef, orderBy('timestamp', 'asc')),
(snapshot) => setMessages(snapshot.docs.map(doc => doc.data()))
);
return () => unsubscribe();
5๏ธโฃ Image Upload Performance ๐ธ
The Problem:
Users uploading 5-10MB phone photos, causing slow uploads and storage concerns.
The Solution:
Client-side image compression before upload - reduced images from 5MB to 200-300KB (95% reduction) while maintaining quality.
๐ Key Lessons Learned
Always research pricing before integrating third-party APIs
Version compatibility matters - check library requirements
Have backup deployment strategies when primary fails
Optimize media files before upload
Real-time features need proper cleanup to prevent memory leaks
Open-source alternatives can be better than paid solutions
Every challenge made the platform more robust and taught valuable lessons about building production-ready applications. ๐โจ
