JS implementation of JSON serialization of BigInt and BigUint types from Rust num-bigint crate

BigInt

const {
    toJSON,
    fromJSON,
} = require('bigint-serde');
 
console.log(toJSON(-123456789123456789n)); // → [-1,[2899336981,28744523]]
console.log(fromJSON([-1,[2899336981,28744523]])); // → -123456789123456789n

BigUint

const {
    toJSON,
    fromJSON,
} = require('bigint-serde/unsigned');
 
console.log(toJSON(123456789123456789n)); // → [2899336981,28744523]
console.log(fromJSON([2899336981,28744523])); // → 123456789123456789n
