Solara#

Ploomber Cloud supports Solara. For information on how to develop Solara apps, please check the documentation.

First, create an account.

To deploy a Solara app you need at least two files zipped up:

  1. Your application file (app.py)

  2. A dependencies file (requirements.txt)

Note that the application will run with Python 3.11. Refer to this section for customized deployments. Here is a sample Docker-based Solara application.

Note

We currently only support Solara deployments via a app.py file, not via .ipynb files

Dependencies#

To deploy a new project, list your dependencies in a (requirements.txt). For example, if you’re using JupySQL, pandas and matplotlib in the solara application, your requirements.txt file will look like this:

# sample requirements.txt
solara
jupysql
pandas
matplotlib

Testing locally#

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

pip install -r requirements.txt

Then run the following command to start the application:

solara run app.py

Deploy#

Deploy from the menu

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

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

Try an example

To download and deploy an example Solara 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 solara/gpt-4-tokenizer

Note

A full list of Solara 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/gpt-4-tokenizer

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.

Production deployments#

Ploomber has features to help you deploy production-ready Solara apps

Authentication#

Our integration with Auth0 allows you to easily add authentication to any Solara app. There’s no need to modify your Solara app code, only pass your Auth0 configuration parameters. Check out the sample app.
