🧰 Advanced Usage

Using in a React Component

\n{`import { useEffect } from \"react\";\nimport { initCamera } from \"https://esm.town/v/dcm31/demoCamera\";\n\nexport default function MyComponent() {\n  useEffect(() => {\n    // Initialize camera when component mounts\n    const destroyCamera = initCamera({\n      size: 120,\n      zoom: 1.3,\n      mirrored: true\n    });\n    \n    // Clean up camera when component unmounts\n    return () => {\n      destroyCamera();\n    };\n  }, []);\n  \n  return Your component content here
;\n}`}\n

\n \n

Direct Component Import

You can also import the CameraView component directly:

\n{`import { CameraView } from \"https://esm.town/v/dcm31/demoCamera\";\n\n// Then use it in your JSX:\n`}\n

\n \n

Try it now! The camera should be visible in the bottom-right corner. Click it to cycle through corners.
