Install the UI component extension to develop Next Experience UI Framework components with the ServiceNow CLI.

## Before you begin

* The ServiceNow CLI must be installed. See [Install the ServiceNow CLI](https://www.servicenow.com/docs/iaxcaOEPEzLHnEr6XrWcsQ "Install the ServiceNow CLI on a Mac, Windows, or Linux machine."). To confirm installation, run the following command:

      $ snc --help

* Configure a default profile to enable the ServiceNow CLI to communicate with an instance. See [Create a default profile](https://www.servicenow.com/docs/384fOQqiISY_gmNlbCMwOg "Create a connection profile that the ServiceNow CLI uses by default. You must create a default profile to set up the CLI's initial connection with an instance.").

Role required: admin

## About this task

The UI component CLI extension provides the commands for developing Next Experience UI Framework components. Commands that connect to a ServiceNow instance use the default ServiceNow CLI profile.  
Note:  
If you use ServiceNow CLI version 1.1.0, you must pass the connection details with each command instead of using a profile.

    snc ui-component develop --loginHost <INSTANCE_URL> --username <USERNAME> --password <PASSWORD>

## Procedure

1. Install the extension by running the following command:  

       snc extension add --name ui-component

2. View the commands that the extension supports by running the following command:  

       snc ui-component --help

3. Update the extension when a new version is available by running the following command:  

       $ snc extension update --name ui-component

4. Remove the extension by running the following command:  

       $ snc extension remove --name ui-component
