High-Concurrency Local-First Web Architecture: 193 Files, Zero Lag

When enterprise web apps grow, database queries slow down, interfaces lag, and workers in fast-paced environments end up waiting on spinning loaders.

Starting in September 2023, I built UAS Central—a local-first platform designed to unify complex facility operations into a high-performance system for operations of: inland inventory, packaging, truck loading, shipping, warehouse management, and cleaning of mixture machines.

114 PHP Files Modular scripts handling backend processing and view logic.

63 JavaScript Files Client-side routines driving interactive workflows.

16 CSS Files Centralized, lean styling.

65 User Pages End-to-end management for inventory, packaging, loading, shipping & cleaning schedules.

115 Data Tables & 48 Views Solid backend data structure powered by SQL Server for fast relational queries and clean data partitioning.

Despite managing 193 assets and supporting 20 concurrent users entering data at peak times, the application operates with zero speed bottlenecks.

Why Local-First Matters

Traditional web apps send every button click across the internet to a distant server. A local-first approach changes the dynamic:

01.

Instant Response: Navigation and data entry update instantly on the user's device, bypassing network latency.

02.

Background Syncing: Updates sync cleanly without locking the UI.

03.

Operational Resilience: If warehouse Wi-Fi drops, work continues uninterrupted and syncs automatically when reconnected.

Scalability Without Bloat

Separating background routines (procs), notifications, and domain modules into isolated files prevents memory bloat, delivering desktop-like speed inside a browser.
