NextJS App Router GPT-Next.js App Router Guidance

Example

A developer transitioning a large application from the Pages Router to the App Router needs to understand how to replace `getStaticProps` with the new data-fetching methods. NextJS App Router GPT would provide a step-by-step explanation, illustrating how to use `fetch()` with `cache` control options for static data fetching.

Scenario

This function is particularly useful during the initial migration phase of a Next.js project, where the developer needs to ensure all components and pages are compatible with the App Router's structure and logic.

Example

When a developer is implementing nested layouts using the App Router, NextJS App Router GPT can demonstrate the correct use of `layout.js` files to achieve the desired structure.

Scenario

This is critical when developing complex applications where multiple nested layouts are required, such as an e-commerce site with different layouts for the homepage, product pages, and checkout.

Example

If a developer is unsure about the correct way to handle global styles in the App Router, NextJS App Router GPT would advise them on the most efficient method, such as colocating global styles within the `app` directory and ensuring they are properly scoped.

Scenario

This function is most beneficial during the development process when maintaining code quality and adhering to best practices is crucial to avoid technical debt and ensure maintainability.
