I want to convert the string to JSON and vice versa. I am using JSON.Stringfy in router.js below. Do I need to have anything particular npm added to project use the JSON.Stringfy function?

Below is the code:

**app.js** file(main file executed by node.exe)

app.get('/about',routes.about);-->calling it using     **http://localhost:3000/about**


**routers.js**

var User = {
'Name' :'',
'EmailId':'',
'Phone':'',
'Address':'',
'favouriteSport':''
 }

exports.about = function(req,res){
res.send("Wele to sports maniac" + JSON.Stringfy(User));
}

seeing below exception:

ItJSON.stringify not JSON.Stringfy.

Pro tip - Next time you see a error message on the lines of xyz is not a function try googling that function name.

https://developer.mozilla/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

I think you have the function name spellt wrong, It's Stringify.

After a lot of research found the JSON npm module. JSON2 is a npm module which is I am using.

Just run the mand in node.js mand prompt :npm install json2 -g Then to add the node module to project run: npm install JSON2 --save
