LWC components can be deleted in two ways.
1. Delete from sfdx
If you want to delete a component “accountCreator” then run below command
sfdxforce:source:delete -m LightningComponentBundle:accountCreator -u username@company.com
2. Delete from the Developer console
- Run below Tooling API query in the Developer console. (make sure to select “use Tooling API” at the bottom)
SELECT Id,apiversion, developerName, FullName, targetConfigs FROM LightningComponentBundle
- Select the component from results and click “Delete Row”.
