How can I use ethers.js to get the token id (34797) from this 0x number?

0x0000000000000000000000000000000000000000000000000000000000034797

I'm not sure which util to use from ethers.js I've looked through the docs and Googled it.

Use BigNumber

hexText = "0x0000000000000000000000000000000000000000000000000000000000034797"
numb = new ethers.utils.BigNumber(hexText).toNumber()
console.log(numb)

No need for ethers.js, you just need to convert it from hexadecimal to decimal:

parseInt('0x34797',16)

214935

(which is different than 34797).

const { BigNumber } = require('ethers').utils;

const hexString = "0x0000000000000000000000000000000000000000000000000000000000034797";

const bigNumber = BigNumber.fromHexString(hexString);

const tokenId = bigNumber.toString();

console.log(tokenId); // "34797"
