Learning Node.js and MongoDB

Writing a mobile app and need to write backend services to support your apps? With the arrays of server-side technologies, it is often mind-boggling to think about the various options available.

Introducing Node.js and MongoDB.

Using Node.js, you can use your favourite programming language - JavaScript, to create server apps rapidly and easily. Node.js is designed to be non-blocking, supports event-driven I/O, and is light weight and efficient. Using Node.js, you can create your own Web server in a matter of minutes. And using it to create RESTful services is both fast and efficient.

While most apps require traditional relational databases, with the advent of mobile apps and location-based services, spatial data is getting more and more common. This is where MongoDB shines. Using MongoDB, you can query spatial data from the database from a single statement. For example, your MongoDB contains a 100,000 places of interest and you need to find the nearest ATM from a current location. How do you do this in SQL? Well, MongoDB does that in a single statement and voila! You got the result in split-seconds.

Windows Phone Tip: Check if App is Running on Emulator

There are times where you want to check if your app is running on the emulator. For example, Bluetooth functionality can only be tested on a real device. Hence, in your code you could check to see if the app is running on an emulator. If it is, then terminate the app.

The following code snippet checks for the current device type. If it is running on an emulator, terminate the app:

//---check if your app is running on the emulator---

if (Microsoft.Devices.Environment.DeviceType ==

    Microsoft.Devices.DeviceType.Emulator)

{

    MessageBox.Show("Running on emulator!");

    //---terminate the app---

    App.Current.Terminate();

}
