Mobile devices generally don't have keyboards, so you'll need to add some haptic controllers to your application. The two popular packages that people seem to be using is FastClick and Hammer. Installation is easy. meteor add fastclick meteor add hammer:hammer FastClick requires nearly no confi...

Before you compile your app and run it on your device, you'll need create some icons and splash screens, and add a mobile-config.js file to your app. App.icons({ // iOS 'iphone': 'resources/icons/icon-60x60.png', 'iphone_2x': 'resources/icons/[email protected]', 'ipad': 'resources/icons...

Now it's time to go through the Meteor Cordova Phonegap Integration documentation. Since that documentation was written, XCode and Yosemite have been released, which has caused some hiccups in installation. Here are the steps we had to go through to get Meteor compiled to an iOS device. Upgrade ...

Register your Apple Developer Account Register an App ID for your app Register the UUID of your testing devices Generate an iOS App Development provisioning profile Generate a CertificateSigningRequest from KeychainAccess Submit CertificateSigningRequest to https://developer.apple.com/accou...

Make sure your development workstation and iPhone are connected to the same WiFi network. Tethering, hotspots, and other ad-hoc networking won't work. Run sudo meteor run ios-device Deploy to your device!

You'll need to separate out your application layer from your database layer, and that means specifying the MONGO_URL. Which means running your app through the bundle command, uncompressing it, setting environment variables, and then launching the project as a node app. Here's how... #make sure you...

Then go into the mongo shell and initiate the replica set, like so: mongo > rs.initiate() PRIMARY> rs.add("mongo-a") PRIMARY> rs.add("mongo-b") PRIMARY> rs.add("mongo-c") PRIMARY> rs.setReadPref('secondaryPreferred')

The replica set will need an oplog user to access the database. mongo PRIMARY> use admin PRIMARY> db.addUser({user:"oplogger",pwd:"YOUR_PASSWORD",roles:[],otherDBRoles:{local:["read"]}}); PRIMARY> show users

Your upstart script will need to be modified to use multiple IP addresses of the replica set. start on started mountall stop on shutdown respawn respawn limit 99 5 script # our example assumes you're using a replica set and/or oplog integreation export MONGO_URL='mongodb://mongo-a...

Oplog Tailing on Sharded Mongo

There's two great utilities for black-box analysis of databases. First is variety.js, which will give you a high-level overview. The second is schema.js, which will let you dig into the collections for more detail on the individual fields. When inheriting a production Mongo database, these two util...

This command will create a /dump directory, and store each collection in a separate BSON blob file. This is the best way to backup or transfer databases between systems. mongodump --db meteor

The analog to the meteordump command is meteorrestore. You can do a partial import by selecting the specific collection to import. Particularly useful after running a drop command. # make sure your app is running meteor # then import your data mongorestore --port 3001 --db meteor /path/to/dump...

Run meteor, open another terminal window, and run the following command. mongoexport --db meteor --collection foo --port 3001 --out foo.json

Importing into a default Meteor instance is fairly easy. Note that you can add a --jsonArray option if your json file is exported as an array from another system. mongoimport --db meteor --port 3001 --collection foo --file foo.json

Mongo supports database-to-database copying, which is useful if you have large databases on a staging database that you want to copy into a local development instance. // run mongod so we can create a staging database // note that this is a separate instance from the meteor mongo and minimongo ins...

Delete the local database files. Just exit the Mongo shell, navigate to the /dbpath (wherever you set it up), and delete the files within that directory.

Did you know about the --url flag? Very handy. meteor mongo --url YOURSITE.meteor.com

They're not easily accessible. If you run the 'meteor bundle' command, you can generate a tar.gz file, and then run your app manually. Doing that, you should be able to access the mongo logs... probably in the .meteor/db directory. If you really need to access mongodb log files, set up a regular mo...

Gotta rotate those log files, or they'll eventually eat up all of your disk space. Start with some research... mongodb-log-file-growth rotate-log-files Log files can be viewed with the following command... ls /var/log/mongodb/ But to set up log-file rotation, you'll need to do the following.....
