Democratizing Application Development with AppSheet

By: Koichi Tsuji, Suvrutt Gurjar, Takuya Miyai

Overview of this book

Many citizen developers regularly use spreadsheets in their business and day-to-day jobs. With AppSheet, you can take your spreadsheets to the next level by enhancing their ease of use. The platform allows you to run your business efficiently and manage it in the field outside of an office or indoor environment. This book enables you to create your own simple or medium to complex hybrid apps for business or personal use. As a beginner to AppSheet, this book will show you how the AppSheet Editor works and how it is used to configure, test, and deploy an app and share it with others as users or co-authors. You’ll learn about widely used features such as how to use data sources, create app views and actions, construct expressions with AppSheet functions, and make your app secure through security and UX options. Next, you’ll create email/attachment templates and develop reports/documents based on templates, store in the cloud, and send files through emails. You’ll also understand how to integrate third-party services and monitor various usage statistics of your app. As you progress, you’ll explore various features with the help of sample apps that you create using the book. By the end of this book, you’ll have learned how to make the most of AppSheet to build powerful and efficient applications.

Controlling what data is sent to a user’s device and security options

As we discussed in Chapter 2, the data in the data source (typically a spreadsheet) will be sent to user devices, such as PCs and mobile phones, when users access the app. When the app users log into the app, the app will first read all the data the app is using from the data source and get that data on the devices the app users are using to access the app. In this case, all the rows in the data sources are sent to user devices without exception. This is pretty much the default behavior of AppSheet. If we imagine tables that have thousands or millions of rows, it will naturally take some time to get the data from the source to the user devices, which will slow down the app’s performance due to the high volume of data the app needs to deal with.

We have a solution to improve your app performance, which is by applying conditions specifying which rows will be sent to user devices through the Security...
