4. Feature Overview

Platform Overview

Nebulajs Cloud is a low-code cloud platform built on Node.js. It is designed for diverse enterprise application development scenarios, system project implementation, and digital transformation across various types of businesses.

Nebulajs Cloud applications are built by combining two types of modules: SaaS common modules and business modules. SaaS common modules are provided centrally by the cloud platform and do not require code generation. Examples include system management and workflow management. Business modules, on the other hand, are generated into code after users configure model properties. Users can then customize and develop these modules flexibly.

Platform Features

1. General Cloud Features

• User Login: System user authentication.
• System Integration: Integrates user authorization and enables quick permission integration with existing applications through JWT + OAuth 2.0.
