Deploying Shiny Apps with RStudio and Shiny Server

When it comes to creating interactive web applications using R, the combination of RStudio and Shiny Server offers a powerful and user-friendly solution. In this article, we will explore the process of deploying a Shiny app locally and then hosting it on a Shiny Server on a Linode.

To begin with, open RStudio and create a new Shiny web app by selecting File > New File > Shiny Web App. This will prompt you to select a directory to store your app's files. Choose a name for your project and click Create. RStudio will automatically generate two new files: `ui.R` and `server.R`. These files contain the code that defines the user interface and server-side logic of your Shiny app.

One of the key benefits of using Shiny Server is its ease of use and flexibility. With Shiny Server, you can host multiple apps on a single Linode without having to worry about configuring web servers or managing databases. Additionally, Shiny Server comes with pre-installed demo apps that provide a starting point for your own development projects.

To deploy your Shiny app locally, open the `server.R` file and edit it to adjust the formatting of the histogram according to your tastes. These files are pre-filled with a demo app that will create an interactive histogram of R's built-in Old Faithful data set.

Once you have made any necessary changes to the `server.R` file, you can run your Shiny app locally by clicking on the Run App button in RStudio. This will launch your app in a web browser and allow you to interact with it.

However, if you want to deploy your Shiny app to the web, you will need to host it on a Shiny Server. To do this, first install the Shiny package by running `install.packages('shiny')` in RStudio. Then, create a new directory on your Linode and upload your Shiny app files to that directory.

Next, configure your Shiny Server by editing the `shiny-server.conf` file. This file controls the behavior of your Shiny Server and allows you to specify which apps should be served and how they should be configured.

Finally, restart your Shiny Server to apply the changes you made to the `shiny-server.conf` file. Your Shiny app will now be available on the web at the URL specified in the `shiny-server.conf` file.

In conclusion, deploying a Shiny app with RStudio and Shiny Server is a straightforward process that can help you create interactive web applications quickly and easily. By following these steps, you can host your own Shiny apps on a Linode and share them with others.
