nuxt.config and layers

Looking structuring out project and it feels like Layers will be useful to keep the different functionality of the project organised. I am however struggling with what I need to be putting in the different nuxt.config filesm and whether I even need to have multiple config files. For example this is a hypothetical tree: 
/app/
    app.vue
/layers
    /base
        /app  -> contains the layout of the application
        nuxt.config
    /jobs
        /app  -> contains pages and logic relating to projects
        nuxt.config
    /peopl
        /app  -> contains pages and logic relating to people
        nuxt.config
nuxt.config.ts
/app/
    app.vue
/layers
    /base
        /app  -> contains the layout of the application
        nuxt.config
    /jobs
        /app  -> contains pages and logic relating to projects
        nuxt.config
    /peopl
        /app  -> contains pages and logic relating to people
        nuxt.config
nuxt.config.ts
At the moment that is 4 nuxt.config files. Which at the moment are all identical. I can see the need for a layer to have it's own config file if it uses a different plugin, but what should I have I'm essentially defining all that at base level?

Hi @dankell.. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You are correct that each Nuxt layer requires its own nuxt.config.ts file—this is how Nuxt recognizes a directory as a layer and allows it to contribute configuration, components, pages, etc., to the final application. However, you do not need to duplicate configuration across all these files unless each layer truly needs to customize or add something specific. Key points from the documentation: - Minimal requirement: Each layer must have a nuxt.config.ts file, but it can be empty or minimal if you don't need to add configuration at that layer. Its presence is mainly to signal to Nuxt that the directory is a layer.
A minimal Nuxt layer directory should contain a nuxt.config.ts file to indicate it is a layer.
Authoring Nuxt Layers - Where to put configuration:
- If you want a setting to apply to all layers and the main app, put it in the base layer's nuxt.config.ts. - If a layer (like /jobs or /people) needs specific configuration (e.g., a plugin, module, or runtime config), add it to that layer's config. - The root nuxt.config.ts is for project-specific configuration and can override or extend what is defined in layers. - You do not need to repeat the same config in every layer unless you want to override or extend something for that layer. - Extending and merging:
The final configuration is merged, with the project root config having the highest priority, then the layers in the order they are extended.
Getting Started with Layers Example: If your layers' nuxt.config.ts files are currently identical and only exist to mark the directory as a layer, you can leave them empty or with minimal content: 
// layers/jobs/nuxt.config.ts
export default defineNuxtConfig({})
// layers/jobs/nuxt.config.ts
export default defineNuxtConfig({})
Only add configuration to a layer's config file if that layer needs something unique. Summary:
You need a nuxt.config.ts in each layer, but you only need to add configuration to them if that layer requires it. Otherwise, keep them minimal. The root config and base layer config are where you should centralize most settings, and only override or extend in other layers as needed. For more, see the official docs on Authoring Nuxt Layers and Nuxt Configuration. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
