Publishing Dash Apps

This is the final chapter of the essential Dash Fundamentals.
The previous chapter covered how to
share state between callbacks.

Now that you’ve got a handle on the basics, it’s time to put your app into the hands of decision makers!

By default, Dash apps run on localhost, meaning that you can only access them on your
own computer. To share a Dash app, you need to publish—or deploy—it to a server.

Plotly provides two platforms whose servers you can use to publish your app: Plotly Cloud and Dash Enterprise.

Plotly Cloud is managed by Plotly, whereas Dash Enterprise is a platform that your organization needs to install and manage.

Publishing to Plotly Cloud is faster, and you can get started for free.

Publishing to Plotly Cloud

This guide shows how to publish to Plotly Cloud from a running Dash app. You can also publish an app by uploading files directly at https://cloud.plotly.com. See Publishing from Local Files for more details.

Note: The total size of your app files must be less than 200 MiB when publishing from dev tools or less than 80 MiB when uploading directly at cloud.plotly.com.

To publish your app to Plotly Cloud:

  1. Create an account if you don’t have one already: https://cloud.plotly.com/

  2. Install the Plotly Cloud extension:
    bash pip install "dash[cloud]"

  3. Run your app in debug mode by setting debug=True on app.run in your app code:

python app.run(debug=True)

When run in debug mode, a Dash app has a dev tools panel with tools for debugging and publishing an app to Plotly Cloud.

  1. Select Plotly Cloud in the dev tools UI and select Sign In.

  2. Authenticate to Plotly Cloud in the browser tab that opens.

  3. Return to your running Dash app in the browser, give the app a name, and select Publish App. Once your app builds and starts, you’ll see an App is live message. Select View App to see it on Plotly Cloud.

  1. (Optional) To share your app with others, configure who can view it from the Cloud UI by selecting Open Settings in Plotly Cloud, going to the Sharing tab, and changing the app visibility:

The Plotly Cloud extension ignores certain files and folders when publishing to Cloud, for example, virtual environments. Configure additional files or folders to ignore using a .gitignore file in your app folder.
