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.

Convert vdom/table/Container.mjs Test from Siesta to Playwright

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

Closed v11.0.0 enhancementhelp wantedgood first issuehacktoberfest

tobiu commented on Sep 27, 2025, 4:09 PM

This task is to migrate the unit test for vdom/table/Container.mjs from the Siesta test harness to the Playwright test runner.

Acceptance Criteria

Create a new test file at test/playwright/unit/vdom/table/Container.spec.mjs.
Translate all assertions from the original file (test/siesta/tests/vdom/table/Container.mjs) to the Playwright/Jest expect syntax.
Ensure the new test runs successfully via npm test.
The new test must cover all the functionality of the original Siesta test.

Hi and thanks for the interest. For this ticket, I strongly recommend to try out the "ai native" workflow: https://github.com/neomjs/neo/blob/dev/.github/WORKING_WITH_AGENTS.md https://github.com/neomjs/neo/blob/dev/.github/AI_QUICK_START.md

=> Gemini was able to rush through several migrations without any help.

Of course you can also do it manually, but it feels a bit like wasting time here.

Thanks for the feedback! I am still polishing the new memory core (other pinned epic). the code is already done, i just need to add the documentation. Inside the Github page of your fork, there is a pull request button. Then you can send the PR to the neo dev branch, and i will add the hacktoberfest-accepted label and merge it in.

tobiu Oct 2, 2025, 9:19 PM

i should add: ideally one PR for each sub, so that both count for the event.

tobiu Oct 2, 2025, 9:20 PM

i will flag more of the testing subs with the hacktoberfest label now.

@KURO-1125 - 2025-10-02T19:33:24Z

Perfect! I've created two separate PRs as requested:

vdom/table/Container migration: migrate-vdom-table-container branch
neo/MixinStaticConfig migration: migrate-neo-mixin-static-config branch

Thanks for flagging more test migration issues with the hacktoberfest label!
