Node.js - Buffer.toJSON() Method
The NodeJS Buffer.toJSON() method returns a JSON object for the given buffer.
Syntax
Following is the syntax of the Node.JS Buffer.toJSON() Method −
buf.toJSON()
Parameters
This method does not have any parameters.
Return value
The method buffer.toJSON() returns a json object.
Example
To create a buffer, we are going to make use of NodeJS Buffer.from() method −
const buffer = Buffer.from('Hello'); console.log(buffer.toJSON());
The buffer is created with the string "Hello".
Output
{ type: 'Buffer', data: [ 72, 101, 108, 108, 111 ] }
Example
In this example the buffer is created with an array of numbers. The Buffer.toJSON() output is as shown below −
const buffer = Buffer.from([1,2,3,4,5,6,7,8,9,10]); console.log(buffer.toJSON());
Output
{ type: 'Buffer', data: [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ] }
You can also make use of the JSON.stringify() method on the Buffer created.
const buffer = Buffer.from([1,2,3,4,5,6,7,8,9,10]); console.log(JSON.stringify(buffer));
Output
{"type":"Buffer","data":[1,2,3,4,5,6,7,8,9,10]}
Example
In this example will make use of the Buffer.alloc() and fill it with a value.
const buffer = Buffer.alloc(10); buffer.fill('H'); console.log(buffer.toJSON());
Output
{ type: 'Buffer', data: [ 72, 72, 72, 72, 72, 72, 72, 72, 72, 72 ] }
