esm: phase two of new esm implementation This PR updates the current `--experimental-modules` implementation based on the work of the modules team and reflects Phase 2 of our new modules plan. The largest differences from the current implementation include * `packge.type` which can be either `module` or `commonjs` - `type: "commonjs"`: - `.js` is parsed as commonjs - default for entry point without an extension is commonjs - `type: "module"`: - `.js` is parsed as esm - does not support loading JSON or Native Module by default - default for entry point without an extension is esm * `--entry-type=[mode]` - allows you set the type on entry point. * A new file extension `.cjs`. - this is specifically to support importing commonjs in the `module` mode. - this is only in the esm loader, the commonjs loader remains untouched, but the extension will work in the old loader if you use the full file path. * `--es-module-specifier-resolution=[type]` - options are `explicit` (default) and `node` - by default our loader will not allow for optional extensions in the import, the path for a module must include the extension if there is one - by default our loader will not allow for importing directories that have an index file - developers can use `--es-module-specifier-resolution=node` to enable the commonjs specifier resolution algorithm - This is not a “feature” but rather an implementation for experimentation. It is expected to change before the flag is removed * `--experimental-json-loader` - the only way to import json when `"type": "module"` - when enable all `import 'thing.json'` will go through the experimental loader independent of mode - based on https://github.com/whatwg/html/issues/4315 * You can use `package.main` to set an entry point for a module - the file extensions used in main will be resolved based on the `type` of the module Refs: https://github.com/nodejs/modules/blob/master/doc/plan-for-new-modules-implementation.md Refs: https://github.com/GeoffreyBooth/node-import-file-specifier-resolution-proposal Refs: https://github.com/nodejs/modules/pull/180 Refs: https://github.com/nodejs/ecmascript-modules/pull/6 Refs: https://github.com/nodejs/ecmascript-modules/pull/12 Refs: https://github.com/nodejs/ecmascript-modules/pull/28 Refs: https://github.com/nodejs/modules/issues/255 Refs: https://github.com/whatwg/html/issues/4315 Refs: https://github.com/w3c/webcomponents/issues/770 Co-authored-by: Myles Borins <MylesBorins@google.com> Co-authored-by: John-David Dalton <john.david.dalton@gmail.com> Co-authored-by: Evan Plaice <evanplaice@gmail.com> Co-authored-by: Geoffrey Booth <webmaster@geoffreybooth.com> Co-authored-by: Michaël Zasso <targos@protonmail.com> PR-URL: https://github.com/nodejs/node/pull/26745 Reviewed-By: Gus Caplan <me@gus.host> Reviewed-By: Guy Bedford <guybedford@gmail.com> Reviewed-By: Ben Coe <bencoe@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Joyee Cheung <joyeec9h3@gmail.com> Reviewed-By: Ruben Bridgewater <ruben@bridgewater.de> Reviewed-By: Сковорода Никита Андреевич <chalkerx@gmail.com> 2018-08-28 17:28:46 +02:00			`import '../common/index.mjs';`
