Deploying Express App

Question

Issue

---

I got the following folder structure:

diaryapp
  nodes_modules
    express
    jade
    mongoose
  public
  routes
  views
  app.js
  package.json

git pushing this to my Joyent Machine will cause a lot of npm errors. I can avoid them by adding mongodb and mongoose to my package.json dependencies, but the service won't start.

I know this is a very small amount of information, if you need further information specify the kind and I ll update my post.

The output:

git push diaryapp.no.de master

Solution/Fix

---

To solve all issues I had to add the devDependencies of mongoose's package.json to the myapp package.json incl. mongoose dependency.

To make this all Joyent SmartMachine node-service ready you have to add

{ "start": "node app.js" }

to your package.json, otherwise node-service does not know which .js to execute as primary.

I will post my entire success story step by step this evening

Answer 1

Since your error is remote: uncaught: Error: Cannot find module 'should' that means you forgot to include the should module as a dependency in package.json.

Ex:

 ...
 "dependencies" : {
   ...
   "should": "0.5.1"
 }
 ...

For more information on package.json checkout: http://package.json.nodejitsu.com/

Answer 2

My solution to this problem: Create a symlink called server.js which links to your application:

ln -s app.js server.js
git commit server.js
git push node master
