Build the App Router mental model before you ship features

May 14, 2025

Understand nesting, layouts, server boundaries, and route ownership so your codebase stays legible.

This article template is designed for practical teaching. A finished version should explain the problem, show the key decision points, and walk through the tradeoffs instead of jumping straight to the final code.

Use the body to connect the concept back to App Router structure, component boundaries, styling decisions, or quality habits so the lesson is transferable beyond a single example.

“Good frontend work is not just making code pass. It is making the decisions behind the code understandable.”

Replace this placeholder with a full lesson, code samples, diagrams, and follow-up exercises so each post becomes part of the broader learning path instead of isolated content.
