Add Packages

Search for and use JavaScript packages from npm here. By selecting a package, an import statement will be added to the top of the JavaScript editor for this package.


Auto Save

If active, Pens will autosave every 30 seconds after being saved once.

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.
