process.chdir() Method in Node.js
The process.chdir() method is used for changing the current directory of the Node.js process. It will throw an exception if any error occurs or the process fails, but will not return any response on success. For Example: It can fail when the specified directory does not exist.
Syntax
process.chdir(directory)
Parameters
directory – This will contain the name of the directory that will be updated in place of earlier directory name.
Example
Create a file with name – chdir.js and copy the below code snippet. After creating file, use the following command to run this code as shown in the example below &Minus;
node chdir.js
chdir.js
// Node.js program to demonstrate the use of process.chdir()
// Importing the process module
const process = require('process');
// Printing present working Directory
console.log("Present working directory: " + process.cwd());
try {
// Updating with the New directory
process.chdir('../tutorialspoint');
console.log("Updated working directory is: " + process.cwd());
} catch (err) {
// Printing error if any occurs
console.error("error occured while " + "changing directory: " + err);
}Output
C:\home
ode>> node chdir.js Present working directory: /home/mayankaggarwal/mysql-test Updated working directory is: /home/mayankaggarwal/tutorialspoint
Example
Let's take a look at one more example.
// Node.js program to demonstrate the use of process.argv
// Importing the process module
const process = require('process');
try {
// Changing the directory with below namey
process.chdir('../not/tutorialspoint');
console.log("New Directory has been succesfully updated");
} catch (err) {
// Printing error if occurs
console.error("Error while changing directory", err);
}Output
C:\home
ode>> node chdir.js Error while changing directory { Error: ENOENT: no such file or directory, chdir '../not/tutorialspoint' at process.chdir (internal/process/main_thread_only.js:31:12) at Object.<anonymous> (/home/mayankaggarwal/mysql-test/process.js:9:9) at Module._compile (internal/modules/cjs/loader.js:778:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10) at Module.load (internal/modules/cjs/loader.js:653:32) at tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js:585:3) at Function.Module.runMain (internal/modules/cjs/loader.js:831:12) at startup (internal/bootstrap/node.js:283:19) at bootstrapNodeJSCore (internal/bootstrap/node.js:623:3) errno: -2, code: 'ENOENT', syscall: 'chdir', path: '../not/tutorialspoint' }
