REACT combines innovative wireless technology

REACT combines innovative wireless technology, cloud-based data and an easy-to-use mobile phone app to create a fully integrated emergency response system. Project management teams receive real-time information from their IoT devices and instantly send customised alerts out to relevant personnel.

What's New in the Latest Version 2.4.1

Last updated on Jun 23, 2024

Create events based on current GPS location, no site selection needed.
Count indicator added to active alarms list.
2FA setting now available at user level (can still be enforced at admin level).
Generic Message event type added.
Introduced delay between SMS and push notification to reduce chance of one alert audio cancelling out the other.
Support for critical notifications (override DND) on iOS devices.
Imminent logout/session expiry notifications.

React is an open-source JavaScript library for building user interfaces. Developed by Facebook, it has gained immense popularity due to its component-based architecture, declarative programming style, and focus on performance.

Component-Based Architecture

React leverages a component-based architecture, where complex UIs are decomposed into smaller, reusable components. Each component encapsulates its own state, logic, and UI, making it easy to maintain and extend applications. Components can be nested, allowing for modular and hierarchical UI structures.

Declarative Programming

React adopts a declarative programming paradigm, where developers describe the desired state of the UI rather than specifying how to achieve it. This declarative approach simplifies development and reduces the risk of introducing bugs. React automatically updates the UI whenever the underlying state changes.

Performance Optimization

React prioritizes performance optimization through several techniques. Its virtual DOM (Document Object Model) allows for efficient updates by only modifying the parts of the UI that have changed. React also uses reconciliation to minimize unnecessary DOM manipulations, improving rendering speed.

State Management

React provides a state management system that allows components to track and update their internal state. This state can be shared among components using a central state store, such as Redux or the Context API. This separation of state from the UI enhances maintainability and code reusability.

Community and Ecosystem

React benefits from a large and active community that contributes to its development and provides extensive support. The ecosystem includes a vast array of third-party libraries, tools, and resources that cater to various application requirements.

Key Features

* Component-based architecture

* Declarative programming

* Virtual DOM for performance optimization

* Efficient state management

* Large and supportive community

* Extensive ecosystem

Use Cases
