The Camera API

In this article by Purusothaman Ramanujam , the author of  PhoneGap Beginner's Guide Third Edition , we will look at the Camera API. The Camera API provides access to the device's camera application using the Camera plugin identified by the cordova-plugin-camera key. With this plugin installed, an app can take a picture or gain access to a media file stored in the photo library and albums that the user created on the device. The Camera API exposes the following two methods defined in the object: getPicture : This opens the default camera application or allows the user to browse the media library, depending on the options specified in the configuration object that the method accepts as an argument cleanup : This cleans up any intermediate photo file available in the temporary storage location (supported only on iOS)

Deploying on your own server

In this article by Jack Stouffer , the author of the book Mastering Flask , you will learn how to deploy and host your application on the different options available, and the advantages and disadvantages related to them. The most common way to deploy any web app is to run it on a server that you have control over. Control in this case means access to the terminal on the server with an administrator account. This type of deployment gives you the most amount of freedom out of the other choices as it allows you to install any program or tool you wish. This is in contrast to other hosting solutions where the web server and database are chosen for you. This type of deployment also happens to be the least expensive option. The downside to this freedom is that you take the responsibility of keeping the server up, backing up user data, keeping the software on the server up to date to avoid security issues, and so on. Entire books have been written on good server management, so if this is not a responsibility that you believe you or your company can handle, it would be best if you choose one of the other deployment options. This section will be based on a Debian Linux-based server, as Linux is far and away the most popular OS for running web servers, and Debian is the most popular Linux distro (a particular combination of software and the Linux kernel released as a package). Any OS with Bash and a program called SSH (which will be introduced in the next section) will work for this article, the only differences will be the command-line programs to install software on the server.
