Overview of this book

This book is a comprehensive guide to the Streamlit open-source Python library and simplifying the process of creating web applications. Through hands-on guidance and realistic examples, you’ll progress from crafting simple to sophisticated web applications from scratch. This book covers everything from understanding Streamlit's central principles, modules, basic features, and widgets to advanced skills such as dealing with databases, hashes, sessions, and multipages. Starting with fundamental concepts like operation systems virtualization, IDEs, development environments, widgets, scripting, and the anatomy of web apps, the initial chapters set the groundwork. You’ll then apply this knowledge to develop some real web apps, gradually advancing to more complex apps, incorporating features like natural language processing (NLP), computer vision, dashboards with interactive charts, file uploading, and much more. The book concludes by delving into the implementation of advanced skills and deployment techniques. By the end of this book, you’ll have transformed into a proficient developer, equipped with advanced skills for handling databases, implementing secure login processes, managing session states, creating multipage applications, and seamlessly deploying them on the cloud.

Deploying the app on Streamlit Cloud

The hardest part is over. From here on, we can follow the same procedure we adopted for the NLP web application. Here are the steps:

  1. Sign into Streamlit Cloud by selecting Continue with Github, authorizing and using the same account you used for GitHub.
  2. Once you’re in, select New app.

You should only have the application we created in Chapter 7 among the deployed applications. The window should look like what’s shown in Figure 11.14:

  1. After selecting New app, in the new form, choose the right repository, the main branch, and the name of the Python file (it should be app.py), and specify a meaningful name to the app URL, as shown in Figure 11.15:
