The stats.isSocket() method is an inbuilt application programming interface of the fs.Stats class which is used to check whether fs.Stats object describes a socket or not.
Syntax:
javascript
Output:
javascript
Output:
stats.isSocket();Parameters: This method does not accept any parameters. Return Value: This method returns a boolean value, which is true if fs.Stats object describes a socket, false otherwise. Below examples illustrate the use of stats.isSocket() method in Node.js: Example 1:
// Node.js program to demonstrate the
// stat.isSocket() Method
// Accessing fs module
const fs = require('fs');
// Calling isSocket() method from fs.Stats
// class using lstat() method
fs.lstat('./', (err, stats) => {
if (err) throw err;
// console.log(`stats: ${JSON.stringify(stats)}`);
console.log(stats.isSocket());
if (stats.isSocket()) {
console.log("fs.lstats describes a Socket.");
} else {
console.log("fs.lstats does not describe a socket.");
}
});
// Using stat() method
fs.stat('./', (err, stats) => {
if (err) throw err;
// console.log(`stats: ${JSON.stringify(stats)}`);
console.log(stats.isSocket());
if (stats.isSocket()) {
console.log("fs.stats describes a socket.");
} else {
console.log("fs.stats does not describe a socket.");
}
});
false fs.lstats does not describe a socket. false fs.stats does not describe a socket.Example 2:
// Node.js program to demonstrate the
// stat.isSocket() Method
// Accessing fs module
const fs = require('fs').promises;
// Calling isSocket() method from
// fs.Stats class
(async () => {
const stat = await fs.lstat('./');
console.log(stat.isSocket());
})().catch(console.error)
falseNote: The above program will compile and run by using the
node filename.js command and use the file_path correctly.
