virtualModules(options)

virtualModules({
	modules: {
		"virtual:feature-flags": "export default { beta: false };",
		"virtual:build-mode": ({ mode }) => `export default ${JSON.stringify(mode)};`,
	},
});

Module IDs must begin virtual: and content must be valid ESM. Consumers supply declare module types; the plugin does not infer them.
