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.

Feat: Generic Sparkline Component & Grid Column

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

Closed v12.0.0 enhancementaifeature

Goal

Promote the DevRank.view.SparklineComponent implementation to a generic framework component (Neo.component.Sparkline) and create a corresponding grid column (Neo.grid.column.Sparkline) to enable widespread usage.

Scope

Create src/component/Sparkline.mjs:
- Extend Neo.component.Canvas.
- Port the controller logic from apps/devrank/view/SparklineComponent.mjs.
- Ensure the renderer connection is configurable.
- Update class names to be generic (e.g., neo-sparkline-canvas).
Create src/grid/column/Sparkline.mjs:
- Extend Neo.grid.column.Component.
- Implement applyRecordConfigs to map record data fields to the component.
- Set Neo.component.Sparkline as the default module.
Create resources/scss/src/grid/column/Sparkline.scss:
- Extract sparkline-specific styles from resources/scss/src/apps/devrank/GridContainer.scss.
- Rename classes to match the generic component (e.g., .neo-sparkline-wrapper).
Export:
- Add Neo.grid.column.Sparkline to src/grid/column/_export.mjs.

Note

The Canvas worker renderer (apps/devrank/canvas/Sparkline.mjs) will be moved in a separate step.

Input from Gemini 3 Pro:

✦ I have successfully implemented the generic Sparkline component and grid column.

Changes:

Promoted Component: DevRank.view.SparklineComponent has been genericized and moved to src/component/Sparkline.mjs. It now supports top-level configuration for dynamic worker renderers (rendererClassName, rendererImportPath).

New Grid Column: Created src/grid/column/Sparkline.mjs. This column type automatically maps record data to the component's values and passes down renderer configurations from the column definition to the component defaults.

SCSS Extraction: Styles were extracted to resources/scss/src/grid/column/Sparkline.scss, making the component stylistically independent.

Integration: DevRank.view.GridContainer was updated to use the new type: 'sparkline' column. The data aggregation logic remains in the component function, while the renderer configuration was moved to the column definition for clarity.

Cleanup: Deleted the obsolete apps/devrank/view/SparklineComponent.mjs.

The implementation allows for easy reuse of worker-based sparklines across the framework while maintaining the "Zero-Config" goal for standard usage.
