  • Last Updated : 05 Jun, 2020

Running Node.js program as an Executable means we do not have to go to the program directory, from anywhere in the terminal, we can execute our program with a specific self-registered word.
There are four steps to follow to run a node.js program as Executable.

  1. Add bin section in package.json
  2. Change index.js file permission (not for windows operating system).
  3. Add comment to index.js file to allow it to be treated like an executable.
  4. Link the project.

Adding bin section in package.json file:

"bin" : {
    "execute" : "index.js"

Note: Add any resanable word in place of ‘execute’.

Change File permission

chmod +x index.js

Add comment to index.js

#!/usr/bin/env node

Command to link projects

npm link

Example 1:

// Adding comment to to index.js
#!/usr/bin / env node
// Code to count length of word
// passed as argument
// Receive argument via command line
const word = process.argv[2];
// Counting length
const length = word.length;
// Printing it to console
console.log(`Words Length : ${length}`);


execute Countlengthofmine!


Example 2:

// Adding comment to to index.js
