Creating Your First Streamlit App

Building a basic Streamlit app can be accomplished in three simple steps:

Step 1: Create a Streamlit App

To get started, ensure you have Python 3.11 or higher installed. Open your terminal and run the following commands:

mkdir streamlit-app  
cd streamlit-app  
touch streamlit_app.py requirements.txt

Next, in your requirements.txt file, list the necessary libraries. For example, if you are utilizing Langchain and OpenAI's GPT, make sure to include them:

langchain  
openai

Install your libraries using:

pip install -r requirements.txt

Now, open your streamlit_app.py file and paste the code required for your app. Once done, you can run your Streamlit app with the command:

streamlit run streamlit_app.py

Step 2: Upload Your App to GitHub

If you haven't created a GitHub account yet, do so first. Then, create a new repository and note the URL. From your terminal, navigate to your app's root folder and execute these commands to push your code to GitHub:

git init  
git add .  
git commit -m "Initial commit"  
git remote add origin   
git push -u origin master

Step 3: Deploy Your GitHub Repository to Streamlit

Create a Streamlit Community Cloud account. Once you have everything set up, navigate to the Streamlit website, click on "New app," and authorize Streamlit to access your GitHub repositories. Choose your repository and the appropriate branch, then specify the main file path (e.g., streamlit_app.py). And that's it!

Final Thoughts

This tutorial showed how easy it is to create and deploy a Streamlit app from a GitHub repository in just three steps. With the ability to build stunning interfaces and leverage the power of AI, you can create truly amazing applications. Now it’s your turn to harness the potential of Streamlit and share your creations with the world!
