Description

Running npm run create-component will ask for a component name and create 3 boilerplate files (svelte, story, and docs). Checks for PascalCase and uses the inquirer package for JS-based CLI functionality (dev-only dependency).

Future features to consider:

• Ask if the folder should be in a subdir of src/lib/
• Ask to use a .docs.mdx template (instead of .docs.md)

Before submitting, please check that you've

• Formatted your code correctly (i.e., prettier cleaned it up)
• Documented any new components or features
• Added any changes in this PR to the CHANGELOG.md Next section

This is so awesome. I took it for a test run and am definitely going to use this in the future. Very glad for the validation, not only of camel case but also if the directory exists already.

This is awesome, I have just 2 things for consideration here:

• What if we refactored to use the more updated version of the inquirer package here.
• Could we make it optional to specify the ComponentName as a command line arg so this could run in a single command? Like npm create-component MyNewComponent ? I'd think if the user leaves the argument off, it would prompt for the name as it currently does, but if they do provide it, it just skips the prompt.

This is fantastic!
