requires are included in the docs

• I have checked issues with bug label and found no duplicates

Expected Behavior

Generated docs should include only exported functions

Actual Behavior

Generated docs include exported functions plus const's from require's

Steps to reproduce the bug

input file

'use strict'

const fs = require('fs')
const os = require('os')
const path = require('path')
const nanoid = require('nanoid')

/**
 * Temporary folder
 *
 * @param {(d: string) => string} transform - Transform function to add prefixes or sufixes to the unique id
 * @returns {string} - Full real path to a temporary folder
 */
const tempdir = (transform = d => d) => {
  const osTmpDir = fs.realpathSync(os.tmpdir())
  return path.join(osTmpDir, transform(nanoid()))
}

module.exports = {
  tempdir
}

    }
}

How can i remove those const in the previous pic ? They are not exported and they are external and still they should up in the docs.

Thank you for your help.

Environment

• Typedoc version: 0.17.3
• Node.js version: 12
• OS: mac os

    "mode": "file",

When you specify this, you tell TS that your files are not modules and everything defined in them is global. File mode should only be used for projects compiled with tsc --module none.
See #1195.

@Gerrit0 didn't help

Managed to remove the require with excludeNotDocumented but that is not ideal.

From the PR you mentioned seems like another approach i tried before, generate declaration with tsc and feed typedoc the declarations and not the source. This works up to a point because i loose almost all the JSDocs comments not related to types, things like examples, param descriptions etc.

Also with typedoc@next i get

Warning: File /Users/hugomrdias/code/pl/js-ipfs-utils/src/temp-dir.js is not a module and cannot be converted in library mode
Warning: File /Users/hugomrdias/code/pl/js-ipfs-utils/src/env.js is not a module and cannot be converted in library mode

and docs are empty.

Ooh, that's good to know thanks! I thought TypeScript would allow CommonJS style exports to produce a symbol at the source file symbol... That's a bug with library mode then, we need to get module symbols for CommonJS modules some other way.

@Gerrit0 mode: 'modules' still doesnt remove requires using excludeNotDocumented is a workaround and i dont even think this option is documented

[Gerrit0]

Looks like you're right! PR welcome if you'd like to fix the docs.

Modules mode should exclude it, but the issue with not being able to get the module symbol in library mode also applies to modules mode.

typedoc/src/lib/converter/factories/declaration.ts

Lines 87 to 98 in c296503

	let parentNode = node.parent;
	while (![ts.SyntaxKind.SourceFile, ts.SyntaxKind.ModuleDeclaration].includes(parentNode.kind)) {
	parentNode = parentNode.parent;
	}
	const parentSymbol = context.getSymbolAtLocation(parentNode);
	if (!parentSymbol) {
	// This is a file with no imports/exports, so everything is
	// global and therefore exported.
	isExported = true;
	} else {
	isExported = !!parentSymbol.exports?.get(symbol.escapedName);
	}

This is an issue that our tests didn't catch since they all use ES modules. Re-opening to track fixing it.
