How to parse a JSON data (type : BigInt) in TypeScript
I guess you need to do something like this,
export interface Address {id_address: string;}Then somewhere in your code where you implement this interface you need to do,
const value = BigInt(id_address); // I am guessing that inside your class you have spread your props and you can access id_address. So inside value you will get your Big integer value.Reference for BigInt.
If you want to make it reliable and clean then always stringify/parse bigint values as objects:
function replacer( key: string, value: any ): any { if ( typeof value === 'bigint' ) { return { '__bigintval__': value.toString() }; } return value;}function reviver( key: string, value: any ): any { if ( value != null && typeof value === 'object' && '__bigintval__' in value ) { return BigInt( value[ '__bigintval__' ] ); } return value;}JSON.stringify( obj, replacer );JSON.parse( str, reviver );
