New exports field in package.json is missing require

[Nadreck]

Describe the bug
When using the exports field in package.json on a package that still needs to support the older require syntax, you need to include require as one of the exports. Otherwise, you get ERR_PACKAGE_PATH_NOT_EXPORTED. Because of this, anyone using the older syntax on feed 5.2.0 is broken.

To Reproduce
Steps to reproduce the behavior:

1. Create a file that imports the feed package using require, such as const Feed = require('feed').Feed;
2. Attempt to run the script.
3. See error

Expected behavior
If you update package.json to:

"exports": {
    ".": {
      "import": "./lib/feed.js",
      "require": "./lib/feed.js",
      "types": "./lib/feed.d.ts"
    }
  },

The script resumes working.

Actual behavior
The script crashes with a Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined error.

Versions (please complete the following information):

• NodeJS: 20.19.6
• TypeScript: n/a
• npm/yarn: npm 11.6.3
• feed: 5.2.0

for those who need this now, you can use something like patch-package for the time being. I'm using yarn patch like this: AndroidDagashi/androiddagashi.github.io@a379ebb
