NodeJS - Appending events to the console.log

Updated:   |  NodeJS articles

Let's say you have a file named app.js that contains the following.

console.log("Hello World");

 

If you use the node CLI to run app.js, "Hello World" should be displayed as stdout on your console.

~]$ node app.js
Hello World

 

On ES6, you could create a constant that contains the timestamp.

const timestamp = () => `[${new Date().toUTCString()}]`
console.log(timestamp() + " Hello World");

 

Better yet, use backticks to include constant variables without having to use + or , to break in and out of strings and constant variables.

const timestamp = () => `[${new Date().toUTCString()}]`
console.log(`${timestamp()}  Hello World`);

 

The console should then contain the timestamp.

~]$ node app.js
[Mon, 08 May 2023 06:51:27 GMT] Hello World
