Node.js process.chdir() Method
The process.chdir() method is an inbuilt application programming interface of the process module which is used to change the current working directory. Syntax:
process.chdir( directory )
Parameters: This method accepts single parameter as mentioned above and described below:
- directory: It is required parameter that specifies the path to the directory to which current working directory to be changed.
Return Value: This method does not return any value on success but throws an exception if fails to change directory specifying that “no such file or directory”. Below examples illustrate the use of process.chdir() method in Node.js: Example 1:
javascript
const process = require( 'process' );
try {
process.chdir( '../os' );
console.log("directory has successfully been changed");
} catch (err) {
console.error("error while changing directory");
}
|
Output:
directory has successfully been changed
Example 2:
javascript
const process = require( 'process' );
console.log("current working directory: "
+ process.cwd());
try {
process.chdir( '../os' );
console.log("working directory after "
+ "changing: " + process.cwd());
} catch (err) {
console.error("error occurred while "
+ "changing directory: " + err);
}
|
Output:
current working directory: C:\nodejs\g\process
working directory after changing: C:\nodejs\g\os
Note: The above program will compile and run by using the node filename.js command. Reference: https://nodejs.org/api/process.html#process_process_chdir_directory
