How to publish an npm package with distribution files?

Question

When you npm publish, if you don't have an .npmignore file, npm will use your .gitignore file (in your case you excluded the dist folder).

To solve your problem, create a .npmignore file based on your .gitignore file, without ignoring the dist folder.

Soure : https://docs.npmjs.com/misc/developers#keeping-files-out-of-your-package

Take a look at the "files" field of package.json file https://docs.npmjs.com/files/package.json#files

From the documentation:

The "files" field is an array of files to include in your project. If you name a folder in the array, then it will also include the files inside that folder. (Unless they would be ignored by another rule.)
