Here is a simple example of how to request access to the user’s camera:
javascript
navigator.mediaDevices.getUserMedia({ video: true })
.then(stream => {
// Use the stream
const video = document.querySelector('video');
video.srcObject = stream;
video.play();
})
.catch(err => {
// Handle the error
console.error("Error accessing the camera", err);
});
This example requests access to the user’s camera, sets the stream as the source of a <video> element on the page, and then plays the video, displaying the webcam’s feed.
