What is the 'Neural Link'?

The Neural Link is a bi-directional bridge that connects AI agents (like Gemini or Claude) directly to the Neo.mjs runtime. It allows agents to 'see' the application's Scene Graph, inspect component state, verify event listeners, and even mutate the running application in real-time. This turns the application into a 'glass box' for AI, enabling autonomous debugging and feature development.

Why is Neo.mjs called an 'Application Engine' instead of a framework?

Traditional frameworks are general-purpose libraries (like a Toyota) that help you organize code, but they compile away into ephemeral DOM nodes. Neo.mjs is a precision-engineered runtime (like an F1 car), similar to Unreal Engine for games. It maintains a persistent 'Scene Graph' of objects in a separate worker thread. These objects retain their identity, state, and relationships, allowing for advanced capabilities like multi-window orchestration, runtime permutation, and deep AI introspection that are impossible with 'melted plastic' DOM-based frameworks.

What is 'Context Engineering'?

Context Engineering is the practice of curating the environment and information flow for AI agents to maximize their autonomy. In Neo.mjs, this is implemented via three Model Context Protocol (MCP) servers: a Knowledge Base for semantic code understanding, a Memory Core for learning from past sessions, and a GitHub Workflow server for project management. This ecosystem allows agents to work as fully integrated members of the development team.

What is 'Object Permanence' in the context of Neo.mjs?

In Neo.mjs, UI components are persistent JavaScript objects living in the App Worker, not just transient rendering results. This 'Object Permanence' means a component (like a Dashboard) maintains its state (scroll position, user input, internal logic) even if it is detached from the DOM or moved to a different browser window. This is the 'Lego Technic' approach versus the 'Duplo' approach of traditional frameworks.

What is an 'Agent Operating System'?

Neo.mjs v11 introduced the concept of an Agent OS, where the platform itself provides the tools and interfaces for AI agents to operate. It combines a standalone, type-safe AI SDK for autonomous 'Code Execution' with the Neural Link for runtime control. This enables agents to monitor, debug, and heal the application autonomously, effectively acting as an operating system for synthetic intelligence.

How does Neo.mjs handle multi-window applications?

Neo.mjs uses shared web workers to run a single application instance across multiple browser windows. All windows share the same application state and data in real-time. Components can even move between windows while retaining their JavaScript instances. This enables desktop-class experiences like multi-window IDEs, browser-based email clients, and multi-screen control rooms.

What makes Neo.mjs different from React, Angular, or Vue?

Neo.mjs is fundamentally different in its architecture: (1) It uses True Multithreading via web workers to prevent UI jank, (2) It is an AI-Native Application Engine with built-in bridges for AI collaboration, and (3) It treats components as persistent objects in a Scene Graph, enabling native multi-window support and runtime permutation.

Update Framework Comparison Guides

Name: Neo.mjs Application Engine
Author: Neo.mjs

Closed v10.0.0-beta.6 enhancement

tobiu commented on Jul 13, 2025, 11:06 AM

Summary

The framework comparison guides located in learn/comparisons/ have been updated to reflect the latest advancements in the Neo.mjs functional component API and core reactivity system. The JSDoc for defineComponent was also updated to serve as a primary source of truth.

Reason for Update

To ensure technical accuracy and to clearly articulate the significant advantages of Neo.mjs's architecture, particularly in contrast to established frameworks like React. The recent finalization of the defineComponent and useConfig APIs provided new insights that needed to be documented.

Key Changes Applied

NeoVsReact.md:
- Re-contextualized React as a legacy industry standard, not a "modern" framework.
- Clarified the "mutability for the developer, immutability for the process" VDOM strategy.
- Detailed the precision of Effect-based rendering vs. React's cascading re-render model, removing the need for manual memoization.
- Added a "Linear Effort for Complexity" section with a concrete example.
NeoVsAngular.md:
- Updated to include the new dual (class-based and functional) component model.
- Contrasted Angular's Zone.js with the surgical precision of Neo.mjs's Effect-based reactivity.
NeoVsSolid.md:
- Refined the comparison between Solid's "run-once" components and Neo.mjs's re-running createVdom effects.
- Clarified the architectural trade-offs (Solid's Main-Thread speed vs. Neo.mjs's guaranteed Main-Thread responsiveness).
NeoVsExtJs.md:
- Updated to highlight the modern dual component model as a clear upgrade path.
- Sharpened the contrast between Ext.js's manual eventing and Neo.mjs's automatic, fine-grained reactivity.
src/functional/defineComponent.mjs:
- The main JSDoc for the function was rewritten to clearly distinguish between:
  - Named configs (static config): For the public component API (props).
  - useConfig(): For private, encapsulated component state.
