I've got a node app built on Hapi using MongoDB and mongoose. Locally, I can use the app without issue. I can connect to the db, add data, find it, etc.
I've created an Ubuntu 14.04 x64 droplet on Digital Ocean.
I can ssh into my droplet and verify that my db is there with the correct name. I'm using dokku-alt to deploy and I have linked the db name to the app using dokku's mongodb:link appName mydb
I was having issues once I deployed the app where it would hang and eventually timeout. After a lot of debugging and commenting out code I found that any time I try to hit mongo like this the app will hang:
var User = request.server.plugins.db.User;
User
.findOne({ id: request.auth.credentials.profile.raw.id })
.exec(function(err, user){
// do something
});
Without this, the app loads fine, albeit without data. So my thought is that mongoose is never properly connecting.
I'm using grunt-shell-spawn to run a script which checks if mongo is already running, if not it starts it up. I'm not 100% certain that this is needed on the droplet, but I was having issues locally where mongo was already running... script:
/startMongoIfNotRunning.sh
if pgrep mongod; then
echo running;
else
mongod --quiet --dbpath db/;
fi
exit 0;
/Gruntfile.js
shell: {
make_dir: {
command: 'mkdir -p db'
},
mongodb: {
command: './startMongoIfNotRunning.sh',
options: {
stdin: false,
}
}
},
And here's how I'm defining the database location:
/index.js
server.register([
{ register: require('./app/db'), options: { url: process.env.MONGODB_URL || 'mongodb://localhost:27017/mydb' } },
....
/app/db/index.js
var mongoose = require('mongoose');
var _ = require('lodash-node');
var models = require('require-all')(__dirname + '/models');
exports.register = function(plugin, options, next) {
mongoose.connect(options.url, function() {
next();
});
var db = mongoose.connection;
plugin.expose('connection', db);
_.forIn(models, function(value, key) {
plugin.expose(key, value);
});
};
exports.register.attributes = {
name: 'db'
};
My app is looking for db files in db/. Could it be that dokku's mongodb:link appName mydb linked it to the wrong location? Perhaps process.env.MONGODB_URL is not being set correctly? I really don't know where to go from here.
