2019-04-25module: initialize module_wrap.callbackMap during pre-executionJoyee Cheung
Since the bootstrap does not actually use ESM at all, there is no need to create this map so early. This patch moves the initialization of the map to pre-execution, so that the only binding loaded in loaders is native_module. In addition, switch to SafeWeakMap.

2019-03-27esm: phase two of new esm implementationguybedford
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>
2019-01-23process: clarify the pre- and post-condition of esm setupJoyee Cheung
This patch: - Clarifies the dependency of the ESM loader initialization (`process.cwd()` and the value of `--loader`) in `node.js`. - Moves the initialization of the per-isolate `importModuleDynamically` and `initializeImportMetaObject` callbacks into `node.js` - Moves the initialization of the ESM loader into `prepareUserCodeExecution()` since it potentially involves execution of user code (similar to `--require` for CJS modules).

At the last TC39 meeting, a new type of Module Records backed by JavaScript source called Dynamic Module Records was discussed, and it is now at Stage 1. Regardless of whether that proposal makes it all the way into the spec, SourceTextModule is indeed a more descriptive and accurate name for what this class represents.

2018-03-15lib: restructure cjs and esm loadersJoyee Cheung
Create `lib/internal/modules` and restructure the module loaders to make the purpose of those files clearer. Also make it clear in the code that the object exported by `lib/internal/modules/cjs/loader.js` is `CJSModule` instead of the ambiguous `Module`. Before: ``` lib ├── ... ├── internal │ ├── loaders │ │ ├── CreateDynamicModule.js │ │ ├── DefaultResolve.js │ │ ├── Loader.js │ │ ├── ModuleJob.js │ │ ├── ModuleMap.js │ │ └── Translators.js │ └── module.js └── module.js ``` After: ``` lib ├── ... ├── internal │ ├── ... │ └── modules │ ├── cjs │ │ ├── helpers.js │ │ └── loader.js │ └── esm │ ├── CreateDynamicModule.js │ ├── DefaultResolve.js │ ├── Loader.js │ ├── ModuleJob.js │ ├── ModuleMap.js │ └── Translators.js └── module.js # deleted in this commit to work with git file mode ``` PR-URL: https://github.com/nodejs/node/pull/19177 Refs: https://github.com/nodejs/node/pull/19112 Reviewed-By: Gus Caplan <me@gus.host> Reviewed-By: Matteo Collina <matteo.collina@gmail.com> Reviewed-By: Benjamin Gruenbaum <benjamingr@gmail.com>
