In this video, I’ll guide you step-by-step on how to build and deploy a multi-page web application in just 15 minutes using Python and Streamlit. No need to worry about HTML, CSS, or JavaScript-everything will be done in Python!
We’ll start by creating a simple navigation menu to switch between different pages and add a fully functional modal contact form. This project will showcase how powerful and easy Streamlit makes web development.
I'll also show you how to integrate no-code tools to enhance your app's functionality, making it even more versatile. By the end of this tutorial, you’ll have a professional-looking web app ready to go. Plus, I’ll teach you how to deploy it on the Streamlit Community Cloud for free, so you can share your work with the world.

I just finished a web app today and was looking for a video on how to upload it. Thanks! Your channel is one of the best for Python!

[@CodingIsFun]

I'm glad to hear it was helpful. Just curious, what kind of app did you create? Cheers, Sven ✌️

[@mdld1293]

@@CodingIsFun We often have to figure out the volumes for stock solution dilutions in our lab. The math is really easy but gets really tedious when you have a bunch of solutions to mix. So, I made an app that automates all that. Just enter the data for your solutions, and it spits out a SOP in PDF format. I think our techs and students are going to love how much easier it makes things!

Hi! Thank you for such high-quality content! 😍 Regarding checking an email for correctness, using regular expressions is a flawed approach because: 1. There are numerous formats all over the world 2. The address might not exist 3. There may be a typo The best way is to send a verification link to the email. I understand that it's off-topic, but worth mentioning, I guess. BTW, the Win + Dot command to see emojis is handy, thanks! 😊

[@CodingIsFun]

Thank you for watching, and I'm glad you liked it! Regarding the email: That's an absolutely valid point. Initially, I considered integrating an email validation API as well, but I wanted to keep the video concise. However, if you're interested in the code, you can check out this form I created for another app: github.com/Sven-Bo/streamlit_contest/blob/main/streamlit_app.py#L17 Basically, I first validate the email and using a dedicated API also has the advantage of filtering out temporary email addresses.

can this be deployed also to a vps like digitalocean?

Way of your explaining everyone can understand easily, My request: Can you create tutorials based on user login,user can access web pages (based on permission)

[@CodingIsFun]

Thank you for watching. I'm glad to hear you like my explanation style. Regarding your request: I'm still waiting for native authentication support from Streamlit. Currently, there are some workarounds and third-party packages available, but I prefer to wait for official Streamlit support for authentication. Cheers, Sven ✌️

[@Bedwarsblockmango0]

@@CodingIsFun Thanks for reply,

[@neetiwason2065]

Can we build a sidebar like the one on the Streamlit documentation webpage (docs.streamlit.io/)? For instance, imagine having sections like "About Me" or "Section 1" with clickable subsections. Clicking on any section or subsection should take me to the corresponding page. How can we achieve this?

[@CodingIsFun]

Thanks for watching. Currently, that does not seem to be supported natively in Streamlit. Cheers, Sven ✌️

[@charleshopper4638]

Is streamlit responsive and how do you handle mobile apps with it? Excellent tutorial. Looking forward to many more.

[@CodingIsFun]

Yes, Streamlit is mobile responsive. You can check out the live website on your mobile phone. Cheers, Sven ✌️

[@Tech-speaker]

Can I add a custom domain to my streamlit webapp?

[@CodingIsFun]

Thank you for watching. In Streamlit Cloud, you can specify a custom subdomain but not change the top-level domain. If you deploy your app on Heroku or Render, you can set up a custom domain. Here are the tutorials for deployment: ▶ Heroku (no free plan): kzbin.info/www/bejne/pHuro4asjt2toKcsi=5N5QWkUwftgFSsUM ▶ Render (free plan available): kzbin.info/www/bejne/aoSyZHaLjLWMnJIsi=HFFruTkzTevHHBsO And here are the instructions for setting up a custom domain: ▶ Heroku: kzbin.info/www/bejne/kIGaeKOugtGrhassi=fNWEbw3xc7xtvtm3 ▶ Render: docs.render.com/custom-domains I hope this helps!
