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.
• **JWT-based authentication** – Secure, standard-compliant authentication mechanism for distributed applications.
• **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** – Can be managed natively as systemd services (start, stop, reload).
• **Complete D-Bus integration** – Native inter-process communication support for Linux server environments.

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.
