Change the New to new . new is the Keyword to create a object using the constructor function in javascript.

Javascript doesn't recognize the New operator that you used in the code and hence you get the error "SyntaxError: Unexpected Identifier" as New is an unexpected identifier.

From MDN

A SyntaxError is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.

var user_schema = New Schema({
    email: String,
    username: String,
    password: String
});

to

var user_schema = new Schema({
    email: String,
    username: String,
    password: String
});
