Optimizing Frontend Project Directory Structures for AI Agents

On November 13, 2026, at 12:38, Juejin published an article titled "How to Organize Frontend Project Directory Structures in the Age of AI Agents". The piece addresses a common pain point in AI Agent development: agents tend to modify code scattered across multiple folders, which raises the cost of reading and editing context. As a response, the article proposes rethinking how a frontend project's directory structure is laid out.

The core suggestion is to move away from a horizontal, type-based layering of files and folders, where components, styles, utilities, and other assets are grouped by kind across the whole project. Instead, the article recommends organizing the codebase vertically by page, so that everything related to a single page stays within one self-contained directory.

The author provides a concrete comparison to back the approach. Under the type-based layout, an AI Agent working on one page would have to reach into 8 separate folders. With the page-oriented structure in place, it only needs to read a single directory, and the number of files involved drops from 8 to 3. The stated goal of the change is to reduce the complexity of context reads and code modifications for AI Agents.

The article closes with a sample directory skeleton and a symptom comparison table that maps common problems to the structural change being proposed. So far, this remains a single standalone proposal with no follow-up developments reported.
