Node.js stats.isDirectory() Method from fs.Stats Class
The stats.isDirectory() method is an inbuilt application programming interface of the fs.Stats class which is used to check whether fs.Stats object describes a file system directory or not.
Syntax:
stats.isDirectory();
Parameters: This method does not accept any parameters.
Return: This method returns a boolean value, which is true if fs.Stats object describes a directory, false otherwise.
Below examples illustrate the use of stats.isDirectory() method in Node.js:
Example 1:
// Node.js program to demonstrate the // stats.isDirectory() Method // Accessing fs module const fs = require('fs'); // Calling fs.Stats isDirectory() fs.stat('./filename.txt', (err, stats) => { if (err) throw err; // console.log(`stats: ${JSON.stringify(stats)}`); console.log(stats.isDirectory()); }); fs.stat('./filename.txt', (err, stats) => { if (err) throw err; // console.log(`stats: ${JSON.stringify(stats)}`); if (stats.isDirectory()) { console.log("fs.Stats describes a " + "file system directory"); } else { console.log("fs.Stats does not " + "describe a file system directory"); } }); |
Output:
false fs.Stats does not describe a file system directory
Example 2:
// Node.js program to demonstrate the // stats.isDirectory() Method // Accessing fs module const fs = require('fs'); // calling fs.Stats isDirectory() fs.stat('./', (err, stats) => { if (err) throw err; // console.log(`stats: ${JSON.stringify(stats)}`); console.log(stats.isDirectory()); }); fs.stat('./', (err, stats) => { if (err) throw err; // console.log(`stats: ${JSON.stringify(stats)}`); if (stats.isDirectory()) { console.log("fs.Stats describes a " + "file system directory"); } else { console.log("fs.Stats does not " + "describe a file system directory"); } }); |
Output:
true fs.Stats describes a file system directory
Note: The above program will compile and run by using the node filename.js command and use the file_path correctly.
