How to include npm packages? Ethers.js?

Hello,

I am wondering how I can include npm packages. I saw that there is a package.json and package-lock.json in the scripts folder, but how can I incorporate those? For example, how is springly included? Simply using "require" doesn't seem to work, although that does the job for lodash.
I am mainly aiming to include the npm module ethers.js.

Thanks.

With Unreal.js, modules that depend on NodeJS won't work.
If you want to use node modules, PuerTS with nodejs backend could be a better choice.
