method Buffer.toJSON
Usage in Deno
import { type Buffer } from "node:buffer";
Buffer.toJSON(): { type: "Buffer"; data: number[]; }
Returns a JSON representation of buf. JSON.stringify() implicitly calls
this function when stringifying a Buffer instance.
Buffer.from() accepts objects in the format returned from this method.
In particular, Buffer.from(buf.toJSON()) works like Buffer.from(buf).
import { Buffer } from 'node:buffer';
const buf = Buffer.from([0x1, 0x2, 0x3, 0x4, 0x5]);
const json = JSON.stringify(buf);
console.log(json);
// Prints: {"type":"Buffer","data":[1,2,3,4,5]}
const copy = JSON.parse(json, (key, value) => {
return value && value.type === 'Buffer' ?
Buffer.from(value) :
value;
});
console.log(copy);
// Prints: <Buffer 01 02 03 04 05>
{ type: "Buffer"; data: number[]; }
