Core: Fix the exports setup to make bundlers work with ESM & CommonJS We cannot pass a single file via the `module` condition as then `require( "jquery" )` will not return jQuery but instead the module object with `default`, `$` & `jQuery` as keys. Instead: 1. For Node.js, detected via the `node` condition: 1. Expose a regular CommonJS version to `require` 2. Expose a tiny wrapper over CommonJS to `import` 2. For bundlers, detected via the `module` condition: 1. Expose a regular ESM version to `import` 2. Expose a tiny wrapper over ESM to `require` 3. If neither Node.js nor bundlers are detected (no `node` or `module` conditions`): 1. Expose a regular CommonJS version to `require` 2. Expose a regular ESM version to `import` The reasons for such definitions are as follows: 1. In Node.js, one can synchronously import from a CommonJS file inside of an ESM one but not vice-versa. To use an ESM file in a CommonJS one, a dynamic import is required and that forces asynchronicity. 2. In some bundlers CommonJS is not necessarily enabled - e.g. in Rollup without the CommonJS plugin. Therefore, the ESM version needs to be pure ESM. However, bundlers allow synchronously calling `require` on an ESM file. This is possible since bundlers merge the files before they are passed to the browser to execute and the final bundles no longer contain async import code. 3. Bare ESM & CommonJS versions are provided to non-Node non-bundler environments where we cannot assume interoperability between ESM & CommonJS is supported. 4. Bare versions cannot be supplied to Node or bundlers as projects using both ESM & CommonJS to fetch jQuery would result in duplicate jQuery instances, leading to increased JS size and disjoint data storage. In addition to the above changes, the `script` condition has been dropped. Only Webpack documents this condition and it's not clear when exactly it's triggered. Adding support for a new condition can be added later without a breaking change; removing is not so easy. The `production` & `development` conditions have been removed as well. They were not really applied correctly; we'd need to provide both of them to each current leaf which would double the size of the definition for the `.` & `./slim` entry points. In jQuery, the only difference between development & production builds is minification; there are no logic changes so we can pass unminified versions to all the tooling, expecting minification down the line. As for the factory entry points: 1. Node.js always gets the CommonJS version 2. Bundlers always get the ESM version 3. Other tools take the ESM version when using `import` and the CommonJS when using `require`. The complexity is lower than for the `.` & `./slim` entry points because there's no default export to handle so Node/bundler wrapper files are not necessary. Other changes: * Tests: Change "node:assert" to "node:assert/strict"; the former is deprecated * Docs: Mention that the CommonJS module doesn't expose named exports * Tests: Run Node & bundler tests for all the above cases Fixes gh-5416 Closes gh-5429 2024-03-11 23:39:34 +00:00			`"use strict";`
