How to check if a file exists synchronously in Node.js?
Published March 31, 2021
To check if a file exists synchronously, you can use the
existsSync() method in the
fs (filesystem) module in Node.js.
Let's say I want to check whether the path
/myFolder/myFile.txt to my file exists or not. Here we can use the
fs.existsSync() method and pass the path to the file to check as the first argument to the method
It can be done like this,
// require filesystem module const fs = require("fs"); // check if file exist // using fs.existsSync() method const doesFileExists = fs.existsSync("./myFolder/myFile.txt"); console.log(doesFileExists); // true
See the above code live in repl.it.
That's it! 😃
