Make screen recorder with html css javascript | screen recorder javascript
Welcome🎉 to Code With Random blog. In this blog, we learn that how we create a screen recorder app. We use HTML & javascript for this screen recorder. Hope you enjoy our blog so let’s start with a basic HTML structure for a screen recorder.
HTML code
<!DOCTYPE html>
<html>
<head>
<title>Parcel Sandbox</title>
<meta charset="UTF-8" />
</head>
<body>
<video class="video" width="600px" controls></video>
<button class="record-btn">record</button>
<script src="./index.js"></script>
</body>
</html>
There is all HTML code for the screen recorder app. Now, you can see output without CSS, then we write javascript for the screen recorder.
output
Now add javascript for functionality.
Javascript code
let btn = document.querySelector(".record-btn")
btn.addEventListener("click", async function () {
let stream = await navigator.mediaDevices.getDisplayMedia({
video: true
})
//needed for better browser support
const mime = MediaRecorder.isTypeSupported("video/webm; codecs=vp9")
? "video/webm; codecs=vp9"
: "video/webm"
let mediaRecorder = new MediaRecorder(stream, {
mimeType: mime
})
let chunks = []
mediaRecorder.addEventListener('dataavailable', function(e) {
chunks.push(e.data)
})
mediaRecorder.addEventListener('stop', function(){
let blob = new Blob(chunks, {
type: chunks[0].type
})
let url = URL.createObjectURL(blob)
let video = document.querySelector("video")
video.src = url
let a = document.createElement('a')
a.href = url
a.download = 'video.webm'
a.click()
})
//we have to start the recorder manually
mediaRecorder.start()
})
Final output
Now we have completed our javascript section, Here is our updated output with javascript. Hope you like the screen recorder. you can see output video and project screenshots. See our other blogs and gain knowledge in front-end development. Thank you 🙏💕
