Create your first component
Learn how to create a component in Parcel.
Give the component a descriptive filename. Component filenames cannot contain
. and must be less than 100 characters. You can differentiate files, folders, and components in the file explorer by their icon.
The component filename (as seen in the file explorer) is unimportant for component use.
When you create a component, the HTML editor window will be replaced by the component editor window. At the top of this window is the Component Name. The Component Name is the same as the component filename by default, but can be changed independent of the component filename. Component names must only contain letters, numbers, and hyphens - no other characters are permitted. Component names must start with a letter. They cannot contain consecutive hyphens (--) or exactly match HTML reserved keywords (ex: 'button').
<style> tags are allowed at the top level in a component. Attempting to use other tags at the top level will result in a warning.
Everything inside a
<component> </component> tag will be rendered when the component is used. Let's start with a simple component called
<component> This will get rendered when this component is used. </component>
Use this component in an email:
<html><body>A simple email<my-first-component></my-first-component></body></html>
The resulting source code will be:
<html><body>A simple emailThis will get rendered when this component is used.</body></html>
Any changes made to the component will propagate to every instance of the component's use.
When you use a component you may want to quickly jump back to it. You can do so by pressing CMD/CTRL + Click on a component to jump to the component file.
