Beeware Web Application
In this article, you will explore the features, benefits, and workflow of building Beeware web applications with examples.
Are you tired of developing separate applications for different platforms, such as Windows, macOS, Linux, iOS, and Android? Do you want to leverage the power of Python for building desktop and mobile applications with a single codebase? Look no further than Beeware, a unique toolkit that allows you to create cross-platform web applications using Python.
The Toga widget toolkit has the capacity to cater to web applications as well! Utilizing the identical API utilized for launching your mobile and desktop applications, you can launch your app as a one-page web application.
Although it has a few features to showcase, it may have bugs and lacks several widgets that are available on other platforms.
It is currently advisable to consider Web deployment as a mere reminder – enough to exhibit the capabilities but not dependable for significant development.
Creating As a Web App
You may find that deploying as a single-page web app follows a familiar pattern – creating the app, building it, and then running it.
However, Briefcase can simplify the process for you.
If you try to run an app and Briefcase detects that it hasn’t been created or built for the specific platform you’re targeting, it will automatically handle the create and build steps.
As it is the first time running the app for the web, you can perform all three steps with just a single command.
macOS
(beeware-venv) $ briefcase run web [helloworld] Generating application template... ... [helloworld] Created build/helloworld/web/static [helloworld] Building web project... ... [helloworld] Built build/helloworld/web/static/www/index.html [helloworld] Starting web server...

Output
How Does It Work?
You may be wondering how the Python code is running in the browser when you press the button on the web app.
The web app is a static website that includes a single HTML source page, along with CSS and other resources.
Briefcase sets up a local web server to serve this page so that your browser can view it. If you plan to put this webpage into production, you can copy the contents of the www folder onto any web server that can serve static content.
To enable Python code to run in the browser, Toga uses PyScript, which provides a Python interpreter. Briefcase packages your app’s code as wheels that PyScript can load in the browser. When the web page is loaded, the application code runs in the browser and builds the user interface using the browser Document Object Model (DOM). When you click on a button, the event handling code runs in the browser.

Benefits of Beeware Web Applications
Beeware web applications offer several benefits for developers and users alike:
- With Beeware, you can write your application logic in Python and run it on different platforms, including Windows, macOS, Linux, iOS, and Android, without having to write platform-specific code. This greatly reduces the development effort required to create applications for multiple platforms, and allows you to reach a wider audience.
- Beeware provides a native, cross-platform widget toolkit (Toga) that allows you to create user interfaces that look and feel like native applications on different platforms. This ensures that your applications provide a consistent and familiar user experience to users, regardless of the platform they are using.
- Beeware allows you to write your application logic in Python, a popular and versatile programming language known for its simplicity and readability. This allows you to leverage the power of Python for application development, including using existing Python libraries and frameworks, and following Pythonic coding conventions.
- Beeware enables you to write code once and reuse it across different platforms, without having to write platform-specific code. This can save significant development time and effort, as you can maintain a single codebase for all platforms, reducing the need for platform-specific bug fixes and updates.
- Beeware provides a high-level abstraction over the underlying native UI frameworks, allowing you to create UIs with minimal boilerplate code. This makes it easy to rapidly prototype and iterate on your application’s UI, speeding up the development process and allowing you to quickly refine your application’s user experience.
Conclusion
You have a powerful tool at your disposal in the form of Beeware web application. This framework allows you to create cross-platform applications using Python, saving you time and effort in building separate applications for each platform. With the Toga widget toolkit, you have access to a consistent API for building user interfaces across different platforms, resulting in responsive and visually appealing interfaces.
