Salesforce LWC for AWS S3 File Uploads

🧩 Project Overview: Developed a custom Lightning Web Component (LWC) integrated with Amazon S3 to enable direct client-side file uploads from Salesforce UI. The component supports multi-section uploads (e.g., Cover Photo, Image 1–10) and dynamically updates the related record fields with the public S3 file URLs via Apex.

🛠️ Key Features: 📸 Multi-file Upload Support with Dynamic Sections (A–K)

☁️ Direct Integration with Amazon S3 using AWS SDK via Static Resource

🧠 Metadata-driven Field Mapping (e.g., Cover_Photo__c, Image_1__c, etc.)

🔁 Real-time UI Feedback using Spinners & File Previews

✅ Automatic Record Update via Apex Controller (updateRecordWithUrl)

🔍 Record Metadata Fetched via Lightning Data Service and @wire (getRecord)

🧠 Highlights: This LWC was designed for use on any record page (e.g., Account, Property__c) and dynamically resolves the SObject type and record ID to correctly update related image fields. The entire file upload and metadata update process occurs seamlessly from the client-side, improving UX and minimizing Apex processing.
