ES6 Modules

NodeJS now is able to have module there is a few differences:

require become import
__dirname, __filename are not available anymore

TypeScript does not add the .js extension to relative imports, so ESM output needs the extension written in the source:

import { MyClass } from "./myclass.js";

Webda packages build with plain tsc under "module": "nodenext", which enforces this. In the Webda repository, scripts/add-import-extensions.mjs adds the missing extensions to older sources.

If you need __dirname or __filename you can use:

import { getCommonJS } from "@webda/core";
const { __dirname, __filename } = getCommonJS(import.meta.url);
