Offline Disaster Communication Platform for Reliable Emergency Coordination in Network-Deprived Environments

An offline disaster communication platform that supports emergency coordination in areas without networks.

An offline disaster communication platform that supports emergency coordination in areas without networks. It is offered as a reference project: a complete, worked example of how a system like this is designed, built and evaluated, so that a developer can study it, run it and learn from it.

It suits learners building full-stack skills: user accounts and roles, a database-backed back end, a responsive front end and deployment.

The main parts are secure sign-up with role-based access, a database-backed back end with a clear API, a responsive interface for each type of user, and an admin view to manage records. The reference build uses React, Node.js, Express, and PostgreSQL, with a clear project structure, setup instructions and sample data so that it can be run and extended.
