EQRcode

Simple QR Code Generator written in Elixir with no other dependencies.

To generate the SVG QR code:

qr_code_content = "your_qr_code_content"

qr_code_content
|> EQRCode.encode()
|> EQRCode.svg()

Options

You can also pass in options into EQRCode.svg():

qr_code_content
|> EQRCode.encode()
|> EQRCode.svg(%{color: "#cc6600", shape: "circle", width: 300})

You can specify the following attributes of the QR code:

• color: In hexadecimal format. The default is #000
• shape: Only square or circle. The default is square
• width: The width of the QR code in pixel. Without the width attribute, the QR code size will be dynamically generated based on the input string.

Default options are %{color: "#000", shape: "square"}.

Installation

def deps do
  [
    {:eqrcode, "~> 0.1.1"}
  ]
end

Credits

We reused most of the code from sunboshan/qrcode to generate the matrix required to render the QR Code. We also reference rqrcode on how to generate SVG from the QR Code matrix.
