🚀 Features
That'll Make You Go WOW
- 🛂 Ask for Permissions - No awkward surprises; we ensure users are in the loop.
- 📸 Capture Images - Snap stunning photos like a pro.
- 🎥 Record Multiple Videos - Be Spielberg, minus the camera crew.
- 💾 Blob It, Download It, Name It - Recorded videos come as blobs, URLs, or downloads with custom names. They are stored hassle free in browser memory without you needing to handle all that stuff manually.
🤷♂️ Why I Created It?
I was working extensively once with these APIs for a project and that experience annoyed me a lot, so I decided to write custom code that time.
I was planning once again to work with same APIs so not to feel that same unpleasant experience again I decided to create this library (hook).
Basic Example
import { useSimpleCamera } from "use-simple-camera";
import { useState, useRef } from "react";
const MyComponent = () => {
const [imageURL, setImageURL] = useState("");
const videoRef = useRef<HTMLVideoElement>(null);
const {
acquirePermissions,
captureImage,
startCamera,
stopCamera,
recordVideo,
stopVideoRecording,
downloadRecordedVideo,
} = useSimpleCamera();
return (
<div>
<button onClick={acquirePermissions}>Permissions</button>
<button onClick={startCamera}>Start</button>
<button onClick={stopCamera}>Stop</button>
<button onClick={() => captureImage().then(setImageURL)}>Capture</button>
<button onClick={() => recordVideo("vid1")}>Record</button>
<button onClick={stopVideoRecording}>Stop Recording</button>
<button onClick={() => downloadRecordedVideo("vid1")}>Download</button>
{imageURL && <img src={imageURL} alt="Captured" />}
{videoRef && <video ref={videoRef} controls />}
</div>
);
};
🧩 How It Works
This hook packs a punch with intuitive, flexible functions. Here’s the action-packed lineup:
- acquirePermissions – Requests user permissions to access camera and microphone.
- startCamera – Starts the camera, enabling media streaming.
- stopCamera – Stops the camera and releases media resources.
- captureImage – Captures an image from the video feed.
- recordVideo – Starts recording a video.
- stopVideoRecording – Stops video recording.
- getRecordedVideoURL – Retrieves the recorded video as a URL.
- getRecordedVideoBlob – Retrieves the recorded video as a Blob.
- downloadRecordedVideo – Downloads the recorded video.
- getMediaStream – Returns a custom media stream based on video/audio tracks.
🪄 Hook Returns
Here’s the magic you'll have at your fingertips:
🟢 Stateful Goodies

🔧 Actions
- Core:
acquirePermissions, startCamera, stopCamera, getMediaStream
- Image:
captureImage
- Video:
recordVideo, stopVideoRecording, getRecordedVideoURL, getRecordedVideoBlob, downloadRecordedVideo
🧙 Pro Tips
- 💡 Permissions First: Always call
acquirePermissions before anything else.
- 🛑 Stop Camera Gracefully: Use
stopCamera to release media devices and avoid leaving them active.
- 🖼️ Capture Image:
captureImage gives you a Base64 blob of your snapshot.
- 🎥 Manage Recorded Videos:
getRecordedVideoURL: Get a URL to the video.getRecordedVideoBlob: Get the raw blob of the video.downloadRecordedVideo: Save the video locally.
- 🎛️ Custom Streaming: Combine
getMediaStream with React refs for custom video streaming, audio-only and video-only streaming.
- ✅ Check video processing status: Check
videoProcessingStatus status for any video before downloading/reading it as blob or as base64 format string.
