$ streamlit hello
Run the Hello app, an example Streamlit app included with the Streamlit library.
Syntax
streamlit hello
Options
The hello command accepts configuration options (just like the run command does). Configuration options are passed in the form of --<section>.<option>=<value>. For example, if you want to set the primary color of your app to blue, you could use one of the three equivalent options:
--theme.primaryColor=blue--theme.primaryColor="blue"--theme.primaryColor=#0000FF
For a complete list of configuration options, see config.toml in the API reference. For examples, see below.
Example
Example 1: Run the Hello app with default settings
To verify that Streamlit is installed correctly, this command runs an example app included in the Streamlit library. From any directory, execute the following:
streamlit hello
Streamlit will start the Hello app and open it in your default browser. The source for the Hello app can be viewed in GitHub.
Example 2: Run the Hello app with a custom config option value
To run the Hello app with a blue accent color, from any directory, execute the following:
streamlit hello --theme.primaryColor=blue
