The API uses similar parameters to the configuration file so you can create an asynchronous function to handle bundling. Add a __POLYFILL__ token to the top of src/main.js: Then set it in the Rollup.js configuration in the ES5 "plugins" array: Run npx rollup --config to build both the ES6 build/bundle.mjs and ES5 build/bundle.js scripts. This is used to validate some misconfiguration errors, but for sufficiently big projects it can slow your build times so if you are confident about your configuration then you might disable those checks with this option. In this example, you can modify the clock selector (__CLOCKSELECTOR__), update time interval (__CLOCKINTERVAL__), and time formatting function (__CLOCKFORMAT__): src/main.js must be modified to use these tokens.

I've been trying to get my application to transpile lit-html to ES5 but have had no luck with this. It's main purpose is to allow other tools for configuration of transpilation without forcing people to add extra configuration but still allow for using their own babelrc / babel config files.
