This room will be available for other users, called viewers, giving them an option to join as the approval of the host of the meeting. The viewers will be able to interact with the broadcaster via a chat functionality that will deliver messages to the entire chat room.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">To <a href=\"https:\/\/www.apphitect.ae\/blog\/build-chat-messaging-app\/\">create chat application<\/a>, you will use Node.JS for the server framework. Web Sockets will handle the communication between peers in each room and WebRTC will manage the broadcasting of the video and voice. But before we get to that, let\u2019s understand what WebRTC is and define thoroughly what it means.<\/span><\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_17 counter-hierarchy\">\n<div

WebRTC stands for Web Real-Time Communication and is basically a technology that allows web applications and sites to capture and \/ or stream audio and\/ or videos. It also enables users to exchange arbitrary data between browsers without requiring an intermediary. In simple words, it helps in transmitting video, voice, or any data between peers.<\/span><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"464\" src=\"https:\/\/www.apphitect.ae\/blog\/wp-content\/uploads\/2023\/07\/webrtc-server.webp\" alt=\"build group video chat web app\" class=\"wp-image-19757\" srcset=\"https:\/\/www.apphitect.ae\/blog\/wp-content\/uploads\/2023\/07\/webrtc-server.webp 1024w, https:\/\/www.apphitect.ae\/blog\/wp-content\/uploads\/2023\/07\/webrtc-server-300x136.webp 300w, https:\/\/www.apphitect.ae\/blog\/wp-content\/uploads\/2023\/07\/webrtc-server-768x348.webp 768w, https:\/\/www.apphitect.ae\/blog\/wp-content\/uploads\/2023\/07\/webrtc-server-150x68.webp 150w, https:\/\/www.apphitect.ae\/blog\/wp-content\/uploads\/2023\/07\/webrtc-server-1000x453.webp 1000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<p><span style=\"font-weight: 400;\">WebRTC is an HTML5 specification that you as a WebRTC developer can use to add real time media communications directly between browser and devices.

After signaling an app must pass ICE server URLs to RTCPeerConnection. ICE tries to find the best path to connect with peers. It tries all possibilities in parallel and chooses the most efficient option that works. ICE first tries to make a connection using the host address obtained from a device&#8217;s operating system and network card. If that fails (which it will for devices behind NATs), ICE obtains an external address using a STUN server and, if that fails, traffic is routed through a TURN relay server.<\/span><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function login(form) \n{   \nvar phone = window.phone = PHONE\n({   number    \n: form.username.value || \u201cAnonymous\u201d, \n\/\/ listen on username line else Anonymous   \npublish_key   : \u2018your_pub_key\u2019,   \nsubscribe_key : \u2018your_sub_key\u2019,  });  \nphone.ready(function()\n{ \nform.username.style.background=\u201d#55ff5b\u201d; \n});  \nphone.receive(function(session)\n{      \nsession.connected(function(session) \n{ \nvideo_out.appendChild(session.video); \n});      \nsession.ended(function(session) \n{ \nvideo_out.innerHTML=\u201d; \n});  \n});  return false;  \n\/\/ So the form does not submit. }<\/code><\/pre>\n\n\n\n<div class=\"recommended-reading\">\n  <div class=\"recommended-header\"><svg class=\"gW_Lq\" style=\"float: left;width: 166px;\" viewBox=\"0 0 210 190\"><defs><path id=\"e26um264ea\" d=\"M18 0h174c9.941 0 18 8.059 18 18v154c0 9.941-8.059 18-18 18H18c-9.941 0-18-8.059-18-18V18C0 8.059 8.059 0 18 0z\"><\/path><\/defs><g fill=\"none\" fill-rule=\"evenodd\"><g><g transform=\"translate(-188 -8232) translate(188 8232)\"><mask id=\"pdc13wuw9b\" fill=\"#fff\"><use xlink:href=\"#e26um264ea\"><\/use><\/mask><circle cx=\"63\" cy=\"95\" r=\"147\" fill=\"#06F\" mask=\"url(#pdc13wuw9b)\"><\/circle><\/g><\/g><\/g><\/svg>\n       <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"122.88\" height=\"101.362\" viewBox=\"0 0 122.88 101.362\" style=\"position: absolute;left: 40px;width: 75px;top: 20px;\">\n       <g id=\"read-book\" transform=\"translate(0 0.002)\">\n         <path id=\"Path_14\" data-name=\"Path 14\" d=\"M12.64,77.27l.31-54.92H6.75V92.23a105.631,105.631,0,0,1,25.68-3.66A72.227,72.227,0,0,1,56.3,92.33a50.968,50.968,0,0,0-16.36-8.88,59.8,59.8,0,0,0-23.66-2.52,3.379,3.379,0,0,1-3.64-3.08,2.81,2.81,0,0,1,0-.58Zm90.98-57.79a4.059,4.059,0,0,1-.04-.51,2.922,2.922,0,0,1,.04-.51V7.34a51.6,51.6,0,0,0-22.86,2.78,31.5,31.5,0,0,0-15.9,12.44V85.9a80.643,80.643,0,0,1,17.58-9.1,50.565,50.565,0,0,1,21.18-3.02V19.48Zm6.75-3.88h9.14a3.372,3.372,0,0,1,3.37,3.37V96.63a3.372,3.372,0,0,1-3.37,3.37,3.28,3.28,0,0,1-1.09-.18c-9.4-2.69-18.74-4.48-27.99-4.54a64.964,64.964,0,0,0-27.08,5.52,3.4,3.4,0,0,1-1.92.56,3.445,3.445,0,0,1-1.92-.56,64.776,64.776,0,0,0-27.08-5.52c-9.25.06-18.58,1.85-27.99,4.54a3.28,3.28,0,0,1-1.09.18A3.352,3.352,0,0,1,0,96.64V18.97A3.372,3.372,0,0,1,3.37,15.6h9.61l.06-11.26a3.366,3.366,0,0,1,2.68-3.28h0a53.466,53.466,0,0,1,29.1,2.23A37.372,37.372,0,0,1,61.61,15.54,39.244,39.244,0,0,1,78.39,3.82a59.114,59.114,0,0,1,29.09-2.8,3.365,3.365,0,0,1,2.88,3.33h0V15.6ZM68.13,91.82a72.556,72.556,0,0,1,22.33-3.26,105.146,105.146,0,0,1,25.68,3.66V22.35h-5.77V77.57A3.372,3.372,0,0,1,107,80.94a3.331,3.331,0,0,1-.78-.09,43.167,43.167,0,0,0-21.51,2.29,75.366,75.366,0,0,0-16.58,8.68ZM58.12,85.25V22.46c-3.53-6.23-9.24-10.4-15.69-12.87A46.533,46.533,0,0,0,19.75,7.18l-.38,66.81a65.191,65.191,0,0,1,22.64,3.06,57.689,57.689,0,0,1,16.11,8.2Z\" fill=\"#fff\"><\/path>\n       <\/g>\n   <\/svg>\n<\/div>\n\t<h3 class=\"has-text-align-center title\"><span class=\"ez-toc-section\" id=\"Now_Its_Tips_for_Build_Educational_Tutoring_Apps\"><\/span>Recommended Reading<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\t<ul class=\"guide\">\n       <li>\n            <a href=\"https:\/\/www.apptha.com\/blog\/what-is-webrtc-and-how-it-works\/\" style=\" float: left; padding-left: 0; cursor: pointer;\"> What is WeBRTC and How Does It Work? \n<\/a>\n       <\/li>\n       <li>\n            <a href=\"https:\/\/www.mirrorfly.com\/blog\/create-audio-video-call-application-using-webrtc-javascript\/\" style=\" float: left; padding-left: 0; cursor: pointer;\"> How to Integrate Audio and Video Calls using WebRTC?\n<\/a>\n       <\/li>\n       <li>\n            <a href=\"https:\/\/www.mirrorfly.com\/blog\/webrtc-video-chat-app-faq\/\" style=\"float: left;  cursor: pointer;\"> WebRTC FAQs (Frequently Asked Questions)<\/a>\n       <\/li>\n   <\/ul>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Summing_Up\"><\/span><strong>Summing Up!<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>We hope that this article has helped you to gain insight into the concepts and connections with regards to <a href=\"https:\/\/www.contus.com\/blog\/webrtc-video-call\/\">WebRTC video call<\/a> P2P communication.
