I have files that use the Node.js framework and other files that I want to implement without using that. When I try to import a class from my node files, where I used module.exports, to my js files, i get the error that "the requested module does not provide an export named default". So is there any way for me to import the node.js class in my JavaScript?

I think only in two methods for solved your problem
METHOD 1
Module1.js
class HelloWorld {
getHelloWorld() {
return 'Hello World';
}
}
module.exports = HelloWorld
Module2.js
const HelloWorld = require('./module1.js');
const helloWorld = new HelloWorld();
METHOD 2 Node <= v12 (Extension file: .msj and run it like node --experimental-modules module2.mjs)
module1.mjs
export default class HelloWorld {
getHelloWorld() {
return 'Hello World';
}
}
module2.msj
import HelloWorld from './module1.mjs';
const helloWorld = new HelloWorld();
console.log(helloWorld.getHelloWorld());
METHOD 2 Node >= v13 (Extension files: .msj or Add { "type": "module" } in the package.json)
module1.mjs or module1.js if you add { "type": "module" } in the package.json
export default class HelloWorld {
getHelloWorld() {
return 'Hello World';
}
}
module2.mjs or module2.js if you add { "type": "module" } in the package.json
import HelloWorld from './module1.mjs';
const helloWorld = new HelloWorld();
console.log(helloWorld.getHelloWorld());
NOTE: If you are interested in knowing the difference between "module.exports vs export default", this topic can help you module.exports vs. export default in Node.js and ES6
