I'm looking for a way to strip tags from a string in the backend using NodeJS. A few answers here have suggested trying node-validator but neither the docs nor any answers explain specifically how to use it.

For instance, I have a string in a variable like this:

INPUT:

var text = '

Hello there! I am a string but not a very exciting one!

DESIRED OUTPUT:

var newText = Hello there! I am a string but not a very exciting one!

The node-validator docs have several options, I think the most pertinent is the trim() function:

var check = require('validator').check,
    sanitize = require('validator').sanitize

//Validate
check('test@email.com').len(6, 64).isEmail();        //Methods are chainable
check('abc').isInt();                                //Throws 'Invalid integer'
check('abc', 'Please enter a number').isInt();       //Throws 'Please enter a number'
check('abcdefghijklmnopzrtsuvqxyz').is(/^[a-z]+$/);

//Sanitize / Filter
var int = sanitize('0123').toInt();                  //123
var bool = sanitize('true').toBoolean();             //true
var str = sanitize(' \t\r hello \n').trim();       //'hello'
var str = sanitize('aaaaaaaaab').ltrim('a');         //'b'
var str = sanitize(large_input_str).xss();
var str = sanitize('<a>').entityDecode();      //''

HTML

Hello there! I am a string but not a very exciting one!
