Deploying MEAN.io to Nodejitsu from Windows machine

Disclaimer: I’m in no way affiliated with Nodejitsu or MEAN.io. I’m just documenting my experience with them – problems (and solutions) I’ve faced while trying these new technologies on a Windows machine.

Great, with that off my chest, we can now start. This is a successor post to the previous one: Getting started with Nodejitsu on Windows by deploying a MEN framework, so you may wanna check that too.

MEAN is a fullstack javascript platform for modern web applications.

MongoDB – leading NoSQL database, empowering businesses to be more agile and scalable

Express – minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications

Angular – lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop

Node.js – a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications

Following the notes on the official website you have to clone the repo, install all the dependencies withnpm  and then run grunt .

git clone http://github.com/linnovate/mean.git

cd mean

npm install

grunt

If you get an error like this:

C:\Users\Nikola\Desktop\mean>grunt

make sure that you have MongoDB installed and that you have the mongod.exe running on the default port 27017. Instructions on how to install MongoDB on a Windows machine can be found here: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/, but tl;dr is:

  • download the installation zip package
  • unzip in c:\mongodb
  • create c:\data\db  folder
  • run c:\mongodb\bin\mongod.exe

When you have mongod.exe  started in one command window (I use Console2) and you run grunt  in other you will get this in the “mongo” console:

C:\mongodb\bin>mongod.exe
mongod.exe --help for help and startup options

Ship it

In order to deploy to Nodejitsu, you have to login to Nodejitsu (jitsu login ) and then run jitsu deploy . At this point I got an error like this:

and naturally, I went looking if someone had a similar issue and it turns out someone on Stackoverflow asked this question. The OP (original poster) did find a solution him self and he said:

The gist of it was I had to move all grunt, karma, and forever dependencies to my devDependencies in the package.json file and change my start to “node server”.

Now, I tried to communicate with the OP to get some more info, but strangely no reply (yet). I figured it out myself in the end and this is how my package.json  file looks like now:

    "supertest": "0.8.2",
    "should": "2.1.1"
  },
  "subdomain": "hitman666-mean2"
}

After making this change I deployed my application once more, and everything went without an error, but when I browsed it on Nodejitsu I got an error

502 Reached max retries limit

I realized that I don’t have a correct MongoDB connection string, and in order to change this I had to edit the file production.js which is in the config/env/  folder.MongoDBconnectionString

I copied the MongoDB connection string from Nodejitsu’s admin dashboard (I wrote about how to set this in my previous post: Getting started with Nodejitsu on Windows by deploying a MEN framework).

After this change I deployed my app again, and now everything was working, yay!
