NuxtJS 3 - Custom module to ignore files in /pages directory

ignore-in-pages-directory.ts

import {defineNuxtModule, extendPages} from "@nuxt/kit";
import type {NuxtPage} from "@nuxt/schema";

/**
 * A function that filters out pages that should be ignored
 * It should return the valid list of pages to replace the original list completely
 * @param pages The list of pages to filter
 * @returns The list of pages to use
 */
type PageFilterFunction = (pages: NuxtPage[]) => NuxtPage[];

/**
 * Object with the functions to filter out pages that should be ignored
 */
const filterFunctions: Record<string, PageFilterFunction> = {
  // You can remove the functions below and add your own.
  // or keep them and add more.
  ignoreComponents: pages => pages.filter(page => !page.path.includes("components")),
  ignoreTsFiles: pages => pages.filter(page => !page.file?.endsWith(".ts"))
}

/**
 * Call all the configured functions and filter out the pages that should be ignored in nuxt module
 */
export default defineNuxtModule({
  setup(_) {
    extendPages((pages: NuxtPage[]) => {
      const validPages = Object.values(filterFunctions).reduce((acc, fn) => fn(acc), pages);
      pages.splice(0, pages.length, ...validPages);
    });
  }
});

Place this file in the <project-root>/modules directory so Nuxt can pick it up automatically. You can name it whatever you want, it doesn't matter. Add your function in the filterFunctions Record and it'll automatically be applied.
