Last Updated :

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:
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:
const fs = require( 'fs' );
fs.lstat( './' , (err, stats) => {
if (err) throw err;
console.log(stats.isSocket());
if (stats.isSocket()) {
console.log( "fs.lstats describes a Socket." );
} else {
console.log( "fs.lstats does not describe a socket." );
}
});
fs.stat( './' , (err, stats) => {
if (err) throw err;
console.log(stats.isSocket());
if (stats.isSocket()) {
console.log( "fs.stats describes a socket." );
} else {
console.log( "fs.stats does not describe a socket." );
}
});
|
Output:
false
fs.lstats does not describe a socket.
false
fs.stats does not describe a socket.
Example 2:
const fs = require( 'fs' ).promises;
(async () => {
const stat = await fs.lstat( './' );
console.log(stat.isSocket());
})(). catch (console.error)
|
Output:
false
Note: The above program will compile and run by using the node filename.js
command and use the file_path correctly.
