Since you are trying to import a module it will be better if you try exporting your classes as a module as well, like this, module.exports = { h1, hello }; and then you can import it in your other file like this, const { h1, hello } = require("./temp");. Hope this solves your problem

Try the first letter in the capital—class Hello and H1.
