The v8.serialize() method is an inbuilt application programming interface of the v8 module which is used to serialize any type of data into a buffer using default serializer.
Syntax:
v8.serialize(value);
Parameters: This method one parameter as described below and mentioned above.
- value: This is a required parameter, refers to any type of data to be serialized by default serializer
Return Value: This method returns a buffer containing serialized data of the passed value.
Below examples illustrate the use of v8.serialize() method in Node.js.
Example 1: Filename: index.js
// Accessing v8 module const v8 = require('v8');
// Calling v8.serialize() console.log(v8.serialize("geeksforgeeks"));
|
Run index.js file using the following command:
node index.js
Output:
<Buffer ff 0d 22 0d 67 65 65 6b 73 66 6f 72 67 65 65 6b 73>
Example 2: Filename: index.js
// Accessing v8 module const v8 = require('v8');
// Calling v8.serialize() serialized_data = v8.serialize("abcdefg");
console.log("\nSerialized data is ");
console.log(serialized_data); serialized_data = v8.serialize(58375693); console.log("\nSerialized data is ");
console.log(serialized_data); serialized_data = v8.serialize(73847.0234); console.log("\nSerialized data is ");
console.log(serialized_data); serialized_data = v8.serialize('\n');
console.log("\nSerialized data is ");
console.log(serialized_data); |
Run index.js file using the following command:
node index.js
Output:
Serialized data is <Buffer ff 0d 22 07 61 62 63 64 65 66 67> Serialized data is <Buffer ff 0d 49 9a f8 d5 37> Serialized data is <Buffer ff 0d 4e ac ad d8 5f 70 07 f2 40> Serialized data is <Buffer ff 0d 22 01 0a>
