Folder dependencies in Node.js

Create file with folder

• We need to create an external file and use module.exports. We can emit module.
• Create a new folder and the a new file named as index.js
• Create a function which accepts an input parameter as string and then logs it to the console

//Pass the message and then log it to the console
module.exports.log=function(msg){
console.log(msg);
}

Refer  the file using require.js

• Specify the path of the JavaScript file to be referred in the file'
• We are not specifying the file name. Based on the name specified in require it would look if there is any existing folder or else it would look for the file.
• Now we can directly use the function as shown below

//Folder dependencies. Based on the name specified in require it would look
//if there is any existing folder or else it would look for the file.
var logger=require("./logger");
logger.log("this is from the log");

• Run the JavaScript code in node

Output

c:\Development\NodeProjects\vanilanode>node app
Reference other file functions in node
this is from the log
