Define a Component

A Lightning web component that renders UI must include:

• An HTML file
• A JavaScript file
• A metadata configuration file

An HTML file is not required for a service component. To ensure that the LWC framework can autowire a component to the correct files, place them in a component folder with the same name as the component's name.

The component can optionally include:

• A CSS file
• An SVG icon
• Additional JavaScript files
• Jest tests
