How to convert a non-decimal string to BigInt

Question

Suppose I have a string of a non-decimal representation of a number beyond Number.MAX_SAFE_INTEGER. How would I get a BigInt of that number?
Were the string a representation of a decimal number, I'd just have BigInt(string), but the number is represented non-decimally.
Note: for my application, efficiency matters.
Edit: I'm looking for a general technique that works for arbitrary bases.

In which base is the number? – Sami Hult Dec 10 '18 at 18:11 — Sami Hult, Dec 10 '18 at 18:11

You could try one of the npm packages for large numbers, such as this:

npm big number
