Service: QR Code Generator - EyevinnOSC/community GitHub Wiki

Getting Started

QR Code Generator is an open source service that creates a QR code image for any URL, with optional logo overlay. Available as a managed service in Eyevinn Open Source Cloud, each instance serves a single QR code at a stable URL — useful for embedding in print materials, landing pages, or digital signage without depending on a third-party QR service.

Prerequisites

Step 1: Create an instance

Navigate to the QR Code Generator service in the OSC web console. Click Create qr-generator and fill in:

Field Description Required
name Instance name (alphanumeric, used in the URL) Yes
GotoUrl The URL the QR code should encode Yes
LogoUrl Public URL of a logo image to overlay in the center of the QR code No

Click Create. Once the status turns green, click the instance card to open it.

Step 2: Retrieve the QR code image

The service exposes the QR code at the root path of the instance URL. For an instance named myqr, the image URL looks like:

https://myqr.eyevinn-qr-generator.auto.prod.osaas.io/

You can embed this directly in an <img> tag or download the image for offline use.

Default credentials

This service has no authentication — the QR code image is publicly accessible at the instance URL.

Usage example

Embed the QR code in a web page:

<img
  src="https://myqr.eyevinn-qr-generator.auto.prod.osaas.io/"
  alt="QR code"
  width="200"
  height="200"
/>

Or fetch and display it in a React component:

function QRCodeImage({ instanceUrl }: { instanceUrl: string }) {
  return <img src={instanceUrl} alt="QR code" width={200} height={200} />;
}

CLI usage

npx -y @osaas/cli create eyevinn-qr-generator myqr \
  -o GotoUrl="https://example.com/landing"

With an optional logo:

npx -y @osaas/cli create eyevinn-qr-generator myqr \
  -o GotoUrl="https://example.com/landing" \
  -o LogoUrl="https://example.com/logo.png"
