I'm playing around with the Cordova hooks capabilities and I'm trying to test using a node application as a hook. In this article: http://devgirl.org/2013/11/12/three-hooks-your-cordovaphonegap-project-needs/ it references running node applications, so I know it's possible.
I've created a simple node application that I'm using to test the before prepare and after prepare process:
#! /usr/bin/env node
console.log("this is a node module");
When I run my prepare, I get the following error:
C:\Users\jwargo\dev\lunchmenu>cordova prepare
The system cannot find the path specified.
Hook failed with error code 1: C:\Users\jwargo\dev\lunchmenu\hooks\before_prepare\test.js
I can't find any information anywhere about what an error code of 1 means here.
I've tested the node code and it runs fine with "node test.js" and when I execute test.js from the command line Windows simply launches my default editor.
So, can anyone tell me what I'm doing wrong or what I need to do to be able to execute a node application as a hook with the Cordova CLI?
Figured it out with some help from the Cordova dev team. The space in my shebang was causing the problem. I removed it and the problem went away.

I have a working react app that I had hosted on a linux environment, but the client has switched their hosting provider and now I have to run the app on a Windows environment. I personally am unfamiliar with Windows and having some serious issues getting my app to work now.
After loads of debugging and testing I now can get my app to run, but when I start it, it will throw some errors which will results in a broken app in the browser.
So when I run npm start it will start up the app and spit out this error:
Screenshot of the terminal error 1/2
Screenshot of the terminal error 2/2
It seems to spit out some complaints when using npm run watchJS which runs this command babel src --watch --out-dir lib.
I am completely lost at this point and have no idea where to go from here.
I can provide as much detail as anyone needs after looking at the question, I just don't know what else to add to this issue and don't want to fill up this question with irrelevant info.
Thanks in advance for any help
It is likely a bug with the version of npm you are using.
See this thread:
https://github.com/npm/npm/issues/18380
Try rolling back your version of npm to 5.3
The issue appears to be exclusive to windows with babel packages.
I'm trying to simply create a React Native project via Webstorm but I get this error upon trying to do so which's resulting in myself not being able to start a project.
Whenever I do choose a Node interpreter it gives me an error that says Unspecified react-native cli package at the same spot that says Please specify node.js interpreter correctly.
I've been starting React Native projects like this since the beginning but this time I get this error out of no where, I don't know where it came from. How can I fix this?
Opens up your terminal, and use the which command to find our your NodeJS interpreter
$ which node
/Users/felixfong/.nvm/versions/node/v8.0.0/bin/node
And copy that result, and update your Node interpreter field inside yoru WebStorm
Hopes this help
I'm trying to run the MEAN stack on windows. I've installed all the pre-requisites (I think) but when I try to start the server via the gulp command I get the error:
Error: Cannot find module 'assetmanager'.
IMAGE:
I have tried running npm install assetmanager which run fine but I still get this error.
This is my first time trying to run node on a machine (I should have used a linux box) so go easy on me as I am learning :-).
Any and all help appreciated.

I had exactly the same problem on Linux Mint 17.2.
The failing way: This was my first project that I'd generated and I don't think I had all the dependencies installed before I ran the init command (g++ was missing).
I tried the npm install assetmanager command as you did and then install worked. Running gulp after this, it got further but this time I was missing mongoose. I installed that then it couldn't find .../config/env/all so I sylinked the default.js config. Then running gulp again, errorhandler was missing. I figured it shouldn't be this hard so...
The working way: I deleted that failure of a project and init'd a new one and it worked. Unfortunately I'm not sure if the init didn't work the first time but I missed the error/warning or something else caused it. All I can recommend is try creating another project and see if that works.
I'm familiar with debugging my own node apps (usually with node-inspector). Today I'd like to debug someone else's program. I'm trying to track down an issue with supervisor. So naturally I just add a --debug (or debug-brk) to the command call, but it passes that to the code that it is supervising.
I've tried adding debugger lines to the js file for supervisor but that didn't work (probably because no debugger was attached at that time). There's a bit of a race here -- I need to start the debugger and attach it to the supervisor process after it starts but before it processes its arguments from the command line.
What I really want to do here is stop supervisor and debug it before it processes its command line arguments. How can I do this?
I had the same problem while developing my hexo blog. The documentation isn't all that complete yet so I find myself needing to reverse engineer at times.
The basic idea is that in Node.js even your cli apps are simply normal node apps that you are exposing to the OS command line interface. On Unix systems you are using this line:
#!/usr/bin/env node
To allow the environment to execute the script.
Many cli based node apps try to insist that you install them globally with the -g option.
npm install -g node-inspector
I personally prefer to have as much control of my development environment as I can get, so I prefer to break some conventions and check my node_modules in to source control along with installing everything I can locally by dropping the -g.
npm install node-inspector
Now you don't have to do this in order to make this work, I'm just describing this setup because it relates to your question. When I run node-inspector I can't simply use:
node-inspector
Instead I must explicitly invoke it from within my project. I do this by executing the symlink in my node_modules/.bin folder:
node_modules/.bin/node-inspector
Now I'm running node-inspector just like you.
Next all I need to do is start the cli process in debug and optionally pass params to it:
node --debug-brk node_modules/.bin/hexo generate
Note I am explicitly calling the symlink here and not simply:
node --debug-brk hexo generate
If I tried the line above I would get an error: "Error: Cannot find module".
I hope this helps.
I am using webstorm 10.0.2 and have used the bangular yeoman template to generate a project. I can run the gulp commands via the gulp window, and I can set a breakpoint in the gulpfile.js and it will hit it, but I can't seem to get it to hit a breakpoint in my server.js
It looks to me like the gulp file is launching another instance of node and thus when you do "debug" from webstorm you are just debugging the gulp.
I also tried with another project using yo hottowel but get the same thing - I am unable to debug the actual application through webstorm.
Can anybody tell me how to configure webstorm so that I can debug the actual server side node code but still use the gulp build tool?
I contacted JetBrains support back in May 2015 and their response was:
It seems this cannot be done quickly. In short, the problem is that serve-dev task starts new process (nodemon) that takes app.js
There is no workaround how to debug such spawned processes right now. We would really appreciate if you'll submit a feature request about it in our YouTrack: https://youtrack.jetbrains.com/issues/WEB
The only way you can try to avoid it - try to create a separate task that will run app.js directly without nodemon process and debug this task instead.
It seems the best option is to use https://www.npmjs.com/package/gulp-node-inspector
