Documentation Is:

• Missing
• Needed
• Confusing
• Not Sure?

Please Explain in Detail...

I have a library of components. Let's say I have

• packageA
  • index.js
• packageB
  • index.js

I'd like this to be on configuration:

export default [
	{
		input: ['packages/A/index.js', 'packages/B/index.js'],
		output: {
			name: '[name]Bundle',
			file: '[name].umd.js',
			format: 'umd'
		}
	},
];

I expect this to output an A/index.umd.js and a B/index.umd.js file, but I get [!] Error: UMD and IIFE output formats are not supported for code-splitting builds.. If I change format --> esm, cjs, etc. it works as expected. I couldn't find any documentation to achieve this with iife/UMD.

I also went on gitter, but didn't hear from anyone.

Your Proposal for Changes

Some documentation to how to build multiple umd files from multiple entry files.
