Deployment Made Simple

Deploying a Streamlit app is a straightforward process that can be accomplished in just three steps:

1. Create Your Streamlit App

To illustrate how to create a Streamlit app, we will build a simple application that utilizes Langchain and OpenAI's GPT to summarize content from a URL. Before we begin, ensure you have Python version 3.11 or higher installed on your machine.

Follow these steps to create your app:

Open your terminal and create a new directory:
```
mkdir streamlit-app
```
Change into the new directory:
```
cd streamlit-app
```
Create a Python file named streamlit_app.py and a requirements.txt file.
Open requirements.txt in your preferred text editor and list the necessary libraries for your application.
Install the libraries via terminal:
```
pip install -r requirements.txt
```
Copy and paste the necessary code into streamlit_app.py.
Save the file and run your app with the command:
```
streamlit run streamlit_app.py
```

2. Upload Your App to GitHub

For version control and deployment, upload your Streamlit app to GitHub. If you don't have a GitHub account yet, create one and then follow these steps:

Create a new repository on GitHub and obtain the repository URL.

In your terminal, navigate to the root folder of your app and execute the following commands:

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

3. Deploy Your GitHub Repository to Streamlit

Finally, you can deploy your app with these steps:

Visit the Streamlit website and create a Community Cloud account.
Once your account is set up, click on "New app" and authorize Streamlit to access your GitHub repositories.
Select your repository and branch, and specify the main file path (e.g., streamlit_app.py).
Your app will now be live, and you can share its URL!
