Introduction
FullJS Documentation
FullJS is a complete ecosystem for developing and running applications with JavaScript. It brings together an embedded V8 runtime, a robust server-side application server with full Linux and systemd integration, a KDE Plasma-like frontend GUI library, an extensive collection of carefully curated libraries, and a powerful web-based IDE featuring drag-and-drop GUI design.
JavaScript Runtime
A multi-threaded, event-driven JavaScript runtime built on the V8 JavaScript engine. The backend is designed to run exclusively on Linux for maximum performance. Supported architectures include:
- amd64
- arm
- arm64
- riscv64
The runtime ensures high performance and efficiency for server-side applications.
Application Server
The FullJS Application Server is designed to provide a robust, modular, and secure foundation for running backend services. It combines modern architectural principles with deep Linux integration to deliver enterprise-grade capabilities.
Key features include:
- **Plugin-based architecture** – Extend and customize server functionality through a modular plugin system.
- **Microservice-oriented design** – Services are isolated and loosely coupled, making them scalable and maintainable.
- **Advanced logging** – Structured logging with runtime-configurable log levels.
- **JWT-based authentication** – Secure, standard-compliant authentication mechanism for microservice design.
- **Built-in user management** – Centralized user handling for authentication.
- **ABAC (Attribute-Based Access Control)** – Fine-grained permission management based on user attributes and policies.
- **Full systemd integration** – Each microservice can be managed natively as systemd services (start, stop, reload, status).
- **Complete D-Bus integration** – Native inter-process communication support for Linux server environments.
Frontend
The FullJS frontend is built for **complex, information-driven web applications** rather than content-oriented websites.
Key features include:
- **KDE Plasma-inspired look & feel** – A modern, desktop-like experience within the browser.
- **Plugin-based design** – Extend the frontend with additional components and modules.
- **Core GUI controls** – Buttons, Dialogs, and essential widgets for building application interfaces.
- **Integrated third party libraries** – Support for advanced tools such as Chart.js for charts and Leaflet for maps and geospatial visualization.
Libraries
FullJS includes a set of essential JavaScript libraries to simplify common development tasks. Examples of core libraries include:
- File system access (`fs`)
- Process and thread management (`Worker`)
- Networking (`socket`, `http`)
- GUI elements for web-based apps
- Charts and data visualization (`ChartJS`)
- Logging and debugging utilities with full Systemd integration
These libraries allow developers to build complex applications with minimal effort.
Web IDE
A web-based Integrated Development Environment (IDE) for creating and managing applications. It enables development of both client-side and server-side code. While the backend requires Linux, client-side applications run in any modern browser (e.g., Google Chrome), making your apps accessible to everyone.
