TypeScript and NodeJS Package and Dependency

TypeScript and NodeJS Package and Dependency


Recently, my project requires a base64 library. I was confused at first.
I think both base64 library works, but they are all nodeJS library. When I have it in my TypeScript project dependencies, they are saying we need something with @type there.
So we need to have something like this:
"@types/base-64": "^0.1.3",
I was thinking this will including base-64 library as well. But actually it does not, we will need both.
"@types/base-64": "^0.1.3",
"base-64": "^0.1.0",

Here is how we use that
import * as base64 from 'base-64';
const msg = base64.decode(msgRaw);
