Node.js - check if file exists

In this article, we would like to show you how to check if file exists in Node.js.

Quick solution:

if (fs.existsSync(path)) {
    // do some action
}

Practical example

In this example, we use fs.existsSync() method inside try-catch block to check if the file exists and print the result in the console.

const fs = require('fs');

const path = './file.txt';

try {
    if (fs.existsSync(path)) {
        console.log("file exists");
    } else {
        console.log("file doesn't exist");
    }
} catch (err) {
    console.error(err);
}
