Hi All I am very new to the nodejs.
I am trying to install the cryptlib module by using the following command for this:
npm install cryptlib
It installing successfully. When I move to myproject ->node_modules the folder called cryptlib is there.
But when I include it in my server.js as follow
var CryptLib = require('cryptlib'),
_crypt = new CryptLib(),
plainText = 'This is the text to be encrypted',
iv = _crypt.generateRandomIV(16), //16 bytes = 128 bit
key = _crypt.getHashSha256('my secret key', 32), //32 bytes = 256 bits
cypherText = _crypt.encrypt(plainText, key, iv),
originalText = _crypt.decrypt(cypherText, key, iv);
Then its throwing an error
module.js:340
throw err;
^

So how can I fix this error? Any help would be appriciated.
Sorry I dont have enough points to reply as a comment before this.
I have updated cryptlib on npm to version 1.0.3 to address this issue. It should work now. Thank you 王庭茂 for your excellent effort.
Also thank you user3446467 for using the module.
If you encounter any further issues please let me know.
It seems to be the problem of the original package. I have sent a pull request to fix this problem. For now, just do what I have done on the pull request and it should work.

is there anyway to fix this? I've been trying to resolve this myself but I give up

This works for me, at the root of the project:
cp -r ./node_modules/m3u8stream/dist ./node_modules/m3u8stream/lib
I really don't understand why, I assume is some bug of versions, (mentioned in the previous comments) cause for some reason it needs the both folders dist and lib (with the same content apparently)
Solved by: Chills
Comment: did you install parse-time?
Answer: no I didn't, I did get it installed but also I've learned from a friend about ytdl-core update required dist instead of lib
Source: https://github.com/fent/node-ytdl-core/pull/520
Solution:
packages needed installing: m3u8stream and parse-time
code needed in main file:
const m3u8stream = require('m3u8stream');
const parseTime = require('m3u8stream/dist/parse-time');
I am getting this error when i try to use node-gcm in my code. I have included it as per standard methods require('node-gcm')
var message = new gcm.Message();

Can someone help me out?
Judging by this issue, it may be that an alpha version of node-gcm was mistakenly published as being the latest stable one.
Until that's fixed, you can try this to get your code working again:
npm install node-gcm#0
EDIT: the issue should be fixed now.
I wanted to create a very minified version of hapi-ninja and came across following problem:
var settings = require('./app/server/config/settings');
var routes = require('./app/server/config/rout');
The first line works as it should an returns my modules. But the second line throws following Exception
AssertionError: path must be a string

I am running on Node v0.10.25 and hapi-ninja is working fine. When I don't require the rout module it does work. My rout and settings modules look very much the same as in hapi-ninja. I isolated the two require statements in one file. Tried both on their own, still the same result. Can't get my head around this. Tried debugging but the value of the node internal path does never change to the above string. Encoding ist always utf-8.
Thank you vkuchartkin and Tracker1.
So my mistake was that I forgot to require a certain directory in my rout.js
var getController = require(module, '../controller');
was my code. Should have been:
var requireDir = require('require-directory');
var get Controller = requireDir(module, '../controller');
Now I feel a bit stupid

Why this application won't start up? I've already tried a global npm install.
In ./models/todo, the period indicates that node will look in the same folder that api.js is in, which would look for \Todo List\routes\models\todo.js. This does not start from the root of the application. To require this, you'll need to us two periods to jump up a level, and specify the app path as well:
var todo = require('../app/models/todo');
maybe you did not set the system value : NODE_PATH; it should point to your global module location;
in Linux: export NODE_PATH=/usr/local/lib/node_modules/ works good for me;
in my case, the file name i had given in my require statement was wrong. I had my models file named posts.js and i was using require('./models/post'). It worked after i changed it to require ('.models/posts')
Hello I'm trying to make some Javascript files working on nodeJS everything is well set however here is the error I get :

C:\>
The files I'm using are :
myServer.js
var my_module = require("./myFunctionsCallTest.js");
console.log("RSA encrypted message :"+ my_module.Encrypt("myKey","myMessage"));
myFunctionsCallTest.js //This file contains some call of prototypes like :
.....................................
RSAKey.prototype.setPublic = RSASetPublic;
RSAKey.prototype._short_encrypt = RSAEncrypt;
RSAKey.prototype.encrypt = RSAEncryptLong;
RSAKey.prototype.encrypt_b64 = RSAEncryptB64;
..............................................
Any idea from where this issue could come?
Thanks.
It looks like you're using Tom Wu's BitInteger and RSA JavaScript library. This library was designed for use in the browser and doesn't work quite right in Node.js.
Luckily, someone has already gone through the work of packaging this library in a Node.js compatible format; it's on GitHub at https://github.com/eschnou/node-bignumber and available via npm as the package "bignumber", and comes with a nice example.
