"res" is not defined

[abhi18av]

Hey, I'm trying to use the wonderful wrapper in NodeJS but for some reason I'm unable to get this thing running. I'm a passionate noob starting out with the Web so could you please help me out a bit.

Here are the specs

'''bash
There was an ERROR: [ReferenceError: res is not defined]
'''

npm - 2.15.5
nodejs - v4.4.5

Directory setup

├── node_modules
│   ├── pokedex-promise-v2
│   └── promise
├── package.json
└── pokefile1.js

Hi, thanks for using this wrapper.
You are getting that error because res is not defined. Usually, this wrapper is used along express.js which lets you do the following:

var express = require('express');
var app = express();

app.get('/', function (req, res) { // res here is a parameter
  res.send('Hello World!'); //you use it for serving content to clients
});

So in the examples we use res to show how to serve the content retrieved from the PokeAPI while using express.

To test if your installation works fine just use this code:

var Pokedex = require('pokedex-promise-v2');
var P = new Pokedex();
P.getBerryByName('chesto')
    .then(function(response) {
      console.log(response);
    })

It will log you the response Object. No need to use res and express
