Props

Prop	Type	Default value	Description

`enableCORS`	`boolean`	`false`	Enable crossorigin attribute
`size`	`number` (in pixels)	`150`	The size of the QR Code
`quietZone`	`number` (in pixels)	`10`	The size of the quiet zone around the QR Code. This will have the same color as QR Code bgColor

`fgColor`	`string` (css color)	`#000000`	Foreground color
`logoImage`	`string` (src attribute)		The logo image. It can be a url/path or a base64 value

`qrStyle`	`squares` \| `dots`	`squares`	Style of the QR Code modules
