Streamlit#

Deploy a Streamlit app on Ploomber in seconds with this guide.

First, create an account.

To deploy a Streamlit app you need at least two files:

  1. Your application file (app.py)

  2. A dependencies file (requirements.txt)

Application file#

Your app.py must be a Streamlit application. An example is available here.

Dependencies#

To deploy a new project, list your dependencies in a (requirements.txt). You must include the streamlit package. If you’re using pandas and numpy together, your requirements.txt file will look like this:

# sample requirements.txt
streamlit
pandas
numpy

Testing locally#

To test your Streamlit app, create a virtual environment and install the packages:

pip install -r requirements.txt

Then run the following command to start the application:

streamlit run app.py

Deploy#

Deploy from the menu

Once you have all your files, create a zip file.

To deploy a Streamlit app from the deployment menu, follow these instructions:

Try an example

To download and deploy an example Streamlit application start by installing Ploomber Cloud and setting your API key:

pip install ploomber-cloud
ploomber-cloud key YOUR-KEY

Tip

If you don’t have an API key yet, follow the instructions here.

Now, download an example. It will prompt you for a location to download the app. To download in the current directory, just press enter.

ploomber-cloud examples streamlit/data-viz

Note

A full list of Streamlit example apps is available here.

You should see a confirmation with instructions on deploying your app. Now, navigate to your application:

cd location-you-entered/data-viz

Deploy from the CLI

Initialize and deploy your app with:

ploomber-cloud init
ploomber-cloud deploy --watch

Tip

To ensure your app doesn’t break on re-deployments, pin your dependencies.
