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