SyntaxError: Invalid or unexpected token, Unable to use plugin with express

[unnisathya92]

Hi @cmartin81, @sierra-m ,

I am trying to use decorative wrapper in my rest server with node + express, I am trying to create an auth filter that will take a JWT token for all the rest endpoints and de-tokenize it and send the payload back to the method.

I have created a plugin similar to log, mentioned in the readme file. PFB

`var wrap = require('decorator-wrap').wrap;

var log = function (callback, args, name, type){
  console.log('Starting  ', type, name);
  var result = callback();
  console.log('Ended: ', name);
  return result;
};

module.exports = function(target, key, descriptor) {
    return wrap(log)(target, key, descriptor);
}
`

I am importing the plugin in my router as below

`var express = require('express');
var router = express.Router();
var serviceAdapterForSendEmail= require('../ServiceAdapters/SendEmail');
const Post = require("../models/Post")
/* GET home page. */
var request = require('request');
var fs = require('fs');
var log=  require('./log');

console.log(log);
@log
router.get('/', function(req, res, next) {
        res.send({
            "login": "unsuccessful"
        });


});


module.exports = router;`

However, when I execute I get the following error

`RestServiceNodeJSForger % npm run start env=local

> [email protected] start /Users/ag33128/CodeBase_Dev/RestServiceNodeJSForger
> node ./bin/www "env=local"
