Dév Web JS Offline Sync
Budget: €8 – €30 EUR
Hello,
I am looking for a JavaScript / Node.js developer to solve a specific issue in an internal web application.
Context
Web application hosted on a local server (Express / Node.js)
Server connected to a local router
No internet connection
Users connect via Wi-Fi using phones or PCs
Problem
Allow data entry even if the Wi-Fi connection drops
Automatically detect whether the user is connected to the correct local Wi-Fi network
Verify the presence of the local server behind the router
Synchronize data as soon as the local connection is restored
Objective
Provide a simple and robust solution suitable for a workshop environment (unstable connection).
Current Stack
HTML / CSS / JavaScript / Node.js / Express
Important constraint:
The server will NOT have internet access and must remain fully isolated.
No cloud-based solution, no external hosting, no VPN, no remote access.
Everything must run locally within the local network only.
