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.

Performance: Remove avatarUrl convert overhead in DevIndex Contributor Model

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

Closed v12.0.0 enhancementaiperformance

tobiu commented on Feb 26, 2026, 3:33 PM

The DevIndex backend spider engine fetches raw avatar_url from the GitHub REST API. Previously, the DevIndex.model.Contributor was performing an expensive convert operation on instantiation to map this into a full URL format under the avatarUrl field.

To optimize performance for 50k+ records, this ticket removes the convert overhead. The model now maps the raw ID string into the avatarUrl field directly.

Consequently, the UI components (GitHubUser, GitHubOrgs, and ProfileContainer) have been updated to smartly detect if avatarUrl is a full HTTP string or just an ID, dynamically constructing the https://avatars.githubusercontent.com/... link at render time. This maintains compatibility for both the highly optimized DevIndex app and general framework usage.

Changes:

apps/devindex/model/Contributor.mjs: Removed convert overhead for avatarUrl and organizations.
apps/devindex/view/home/ProfileContainer.mjs: Updated getAvatarUrl() to handle raw IDs.
src/component/GitHubUser.mjs: Updated URL construction logic.
src/component/GitHubOrgs.mjs: Updated URL construction logic.
src/grid/column/GitHubUser.mjs: Mapped avatarUrl from record.avatarUrl.

Input from Gemini 3.1 Pro:

✦ Successfully completed and pushed to the dev branch in commit 29bb47d1e.

Summary of Completion:

Reverted changes to apps/devindex/services/Updater.mjs to protect the backend spider logic.

Removed convert overhead for avatarUrl and organizations array inside DevIndex.model.Contributor.

Updated apps/devindex/view/home/ProfileContainer.mjs to resolve avatarUrl from raw IDs.

Refactored src/component/GitHubUser.mjs and src/component/GitHubOrgs.mjs to accept both raw IDs and full URL strings, ensuring backwards compatibility for other applications.

Adapted src/grid/column/GitHubUser.mjs to fetch avatarUrl.
