"Using npm packages" / problem 2 - issue with "prompt"

[danielbush]

Hi, My node doesn't have "prompt". If I use the "prompt" npm module, the solution looks different to the one I can see in https://github.com/substack/browserify-adventure/blob/master/solutions/using_npm_packages/main.js currently.

So I tried using npm "prompt" but I get an error when piping to browserify-adventure run. (I get: "undefined:869 \n var files = fs.readdirSync(dir); ...")

Node does not have prompt, browsers do. If you would like to run the solution yourself, you should follow the instructions from the first exercise:

We piped the output of browserify into the verify command directly, but ordinarily to use browserify in your page you would do:

browserify beep_boop.js > bundle.js

and then in your html, you just add a single

Open html page in the browser and turn on the console to see the output.

I am getting the same problem - how should verify be run?

Here's my code which runs fine stand alone

var uniq = require("uniq") var prompt = require('prompt')

prompt.start() prompt.get(['message'], function(err, result) { console.log(uniq(result.message.split(','))) })

Here's my output

prompt: message: one,two,three,two,three,four,three,four,five,six [ 'five', 'four', 'one', 'six', 'three', 'two' ]

When I follow the directions to verify or run
