Setting 'excludeExternals' doesn't exclude imports from node_modules

[busygraybird]

I use typedoc in my JS script to generate documentation for multiple packages in monorepo. I run the script, but get types from node_modules in -internal- folder. Setting excludeExternals to true doesn't exclude this types. I tried to set different patterns to externalPattern option: /node_modules/, node_modules/**/*.ts, **/node_modules/**, but nothing solve the problem.

Expected result: only internal types from my packages will be included in the generated documentation and any types from node_modules will be removed from result.

Here is my script with typedoc config:

import * as td from "typedoc";
import { glob } from "glob";
import fs from "fs";
import { repoRootDir } from "@biom/config/utils/monorepo.js";
import path from "path";

const generatedDocsDir = "apps/docs/pages/packages";

const packages = glob
  .sync("./packages/*", {
    absolute: true,
    cwd: repoRootDir,
  })
  .filter((dir) => fs.existsSync(path.resolve(dir, "typedoc.json")));

await fs.promises.rm(generatedDocsDir, { recursive: true, force: true });

const app = await td.Application.bootstrapWithPlugins({
  entryPoints: packages,
  exclude: ["packages/example"],
  name: "BIOM Packages",
  entryPointStrategy: "packages",
  excludeScopesInPaths: true,
  fileExtension: ".mdx",
  includeVersion: false,
  compilerOptions: {
    skipLibCheck: true,
  },
  packageOptions: {
    includeVersion: true,
    entryPoints: ["src/index.ts"],
  },
  outputs: [
    {
      name: "markdown",
      path: generatedDocsDir,
    },
  ],
  out: generatedDocsDir,
  plugin: [
    "typedoc-plugin-markdown",
    "typedoc-plugin-mdn-links",
    "typedoc-plugin-missing-exports",
    "@biom/typedoc-plugin-changelog",
    "@biom/typedoc-plugin-pretty-navigation",
  ],
  categorizeByGroup: false,
  groupReferencesByType: false,
  expandObjects: true,
  readme: "none",
  hidePageHeader: true,
  hideBreadcrumbs: true,
  expandParameters: true,
  useHTMLEncodedBrackets: true,
  parametersFormat: "table",
  interfacePropertiesFormat: "table",
  enumMembersFormat: "table",
  propertyMembersFormat: "table",
  typeDeclarationFormat: "table",
  classPropertiesFormat: "table",
  typeDeclarationVisibility: "compact",
  pageTitleTemplates: {
    index: "{projectName} {version}",
    member: "{name}",
    module: "{name}",
  },
  navigation: {
    includeCategories: false,
    includeGroups: false,
    includeFolders: false,
    compactFolders: true,
    excludeReferences: true,
  },
  excludeExternals: true,
  externalPattern: "**/node_modules/**",
  excludeReferences: true,

  placeInternalsInOwningModule: true
});

const project = await app.convert();

if (project) {
  await app.generateOutputs(project);
}

Sorry for my English and thanks for the help!

See https://typedoc.org/documents/Options.Package_Options.html

That option also needs to be set in packageOptions so that it takes effect during conversion. The option is not set when converting with your current script.
