uvicorn:tldr:4c492

The command you provided:

uvicorn --host ${localhost} --port ${8080} ${import-path:app_object}

is used to run a web server using the Uvicorn ASGI server. Let's break down the command:

• uvicorn is the command-line utility for running Uvicorn.
• --host ${localhost} specifies the host on which the server should listen. ${localhost} is most likely meant to be replaced with the actual value of localhost, which refers to the local machine.
• --port ${8080} specifies the port number on which the server should listen. ${8080} is most likely intended to be replaced with a specific port number, such as 8000 or 5000.
• ${import-path:app_object} specifies the import path to the ASGI application object. ${import-path} is likely to be replaced with the actual import path of your ASGI application, and ${app_object} is likely to be replaced with the name of the application object.

Overall, this command is meant to start a Uvicorn server on the specified localhost and 8080 port, serving the ASGI application defined by the import path and app object name provided.
