Node.js Stream writable.writableObjectMode Property

The writable.writableObjectMode property in Stream module is used to get the object mode value of the Writable stream. Syntax:

writable.writableObjectMode

Return Value: It returns true if the objectMode is set to true otherwise returns false. Below examples illustrate the use of writable.writableObjectMode property in Node.js: Example 1:

javascript

// Node.js program to demonstrate the     
// writable.writableObjectMode Property
 
// Accessing stream module
const stream = require('stream');
 
// Creating a stream and creating 
// a write function
const writable = new stream.Writable({
 
  // setting value of objectMode
  objectMode: true,
 
  // Write function with its 
  // parameters
  write: function(chunk, encoding, next) {

    // Converting the chunk of
    // data to string
    console.log(chunk.toString());
    next();
  }
});

// Writing data
writable.write('GfG')
 
// Calling writable.writableObjectMode 
// Property
writable.writableObjectMode;

Output:

GfG
true

Example 2:

javascript

// Node.js program to demonstrate the     
// writable.writableObjectMode Property
 
// Accessing stream module
const stream = require('stream');
 
// Creating a stream and creating 
// a write function
const writable = new stream.Writable({
 
  // Write function with its 
  // parameters
  write: function(chunk, encoding, next) {
 
    // Converting the chunk of
    // data to string
    console.log(chunk.toString());
    next();
  }
});
 
// Writing data
writable.write('GfG')
 
// Calling writable.writableObjectMode 
// Property
writable.writableObjectMode;

Output

GfG
false

Here, the objectMode is not set so, by default it is set to false. Reference: https://nodejs.org/api/stream.html#stream_writable_writableobjectmode
