دانلود کتاب Streamlit برای توسعه وب

It was a typical night when, just as I was about to fall asleep, my phone buzzed. Being a millennial, I couldn’t resist checking it, only to find another annoying email advertisement for something called “Streamlit.” Normally, I’d ignore it, but for some reason, the sleek Streamlit logo caught my eye. In hindsight, I’m glad I clicked on the ad. Since then, my programming life has been closely linked to a framework I had been hoping someone would create—the powerful Streamlit. Early in my career, I noticed that many skilled Python developers, including myself, excelled in backend and server-side programming but struggled with frontend user interfaces and client-side software. While Flask and Django made efforts to address this, both required significant knowledge of HTML, CSS, and HTTP, making them tough to use. I often turned to Tkinter and PyQt for local desktop applications, but I couldn’t deploy anything to the cloud. What we needed was a pure Python web framework with an intuitive API that allowed easy creation and deployment of web applications, focusing primarily on the backend. Essentially, something like ReactJS but for Python. And when I clicked that ad, I found exactly what I was looking for. It was a eureka moment! This happened in the summer of 2020, and Streamlit had only been publicly released in the fall of 2019. In less than a year, the development team had crafted a framework and API that matched my needs perfectly. Since then, Streamlit has only grown in popularity, and for me, it came at the perfect time. I had just joined Iberdrola and was tasked with developing a Python-based web application. Before Streamlit, I would have hesitated to even consider deploying applications to the web, but now, I was advocating for web applications, proudly showcasing Streamlit’s capabilities. In no time, I became a trailblazer within my development team. As with all great discoveries, it felt wrong to keep it to myself. I decided to share Streamlit’s potential with the world, and this book is the result. It’s written for developers who, like me, have struggled with creating and deploying web applications. This book offers a comprehensive guide to Streamlit, from simple use cases to building complex, cloud-based applications. By the end of this book, readers will not only understand how to use Streamlit, but also how to integrate their web applications with powerful server-side infrastructures like MongoDB, PostgreSQL, Linux, Windows Server, and Streamlit’s deployment platform. The goal is to empower readers to take their ideas and bring them to the web, possibly even kickstarting their own ventures.
