海外TECH	DEV Community	Build a video call app with Svelte in an afternoon	https://dev.to/trydaily/build-a-video-call-app-with-svelte-in-an-afternoon-4h7b	Build a video call app with Svelte in an afternoonDaily s JavaScript library daily js is compatible with any frontend framework which means choosing your stack is really up to you Today we ll be looking at one of our favourite frameworks at Daily Svelte In today s tutorial we ll rebuild our Daily Prebuilt demo already built in React and Vue but this time with Svelte Specifically we ll cover how to Embed Daily Prebuilt in a Svelte appHandle updating your components based on whether you ve joined a Daily call or notManage your Daily Prebuilt call with a custom control panelIf you want to test the completed version of the demo first check out the deployed version What exactly is Svelte Svelte is an open source frontend component framework that can be used as an alternative to other frontend frameworks like React or Vue It differs from other frameworks based on how it updates your app s UI Instead of using a virtual DOM to handle app changes like React uses Svelte is instead a compiler that converts app components to JavaScript and inserts any UI changes directly into the DOM itself Or as the Svelte docs put it “Svelte runs at build time converting your components into highly efficient imperative code that surgically updates the DOM As a result you re able to write ambitious applications with excellent performance characteristics Who is this tutorial for Since this is a Svelte tutorial the following content will be most helpful for anyone already familiar with Svelte In case you re not we ll do our best to explain what is unique to Svelte Thankfully Svelte also has amazing documentation and interactive tutorials to learn the basics and we highly recommend giving those a read Getting startedTo get started locally clone the Daily Prebuilt Svelte demo app and run the following commands in your terminal npm inpm run devYou will also need to create a Daily account and a new Daily room for testing the demo Note The demo README includes additional instructions for creating new Daily rooms locally via the app Once you have the app running locally navigate to http localhost in your browser of choice and you should see the home page App svelte Determining which view to showOur app is going to have two possible views Our home page which includes a form to join a callThe call UI which includes the Daily Prebuilt embed and our custom call controlsWe know we ll need some logic to determine which view should show To determine this let s take a look at our parent App component App will handle deciding whether the Home or Call component is rendered App svelte lt script gt import Call from screens Call svelte import Header from components Header svelte import Home from screens Home svelte let currentScreen home call let url let userName const handleJoinCall detail gt currentScreen call set component vars with form submission values url detail url userName detail name save in local storage localStorage setItem svelte prebuilt url url localStorage setItem svelte prebuilt name userName const handleLeaveCall gt currentScreen home lt script gt lt svelte head gt lt script crossorigin src daily co daily js gt lt script gt lt svelte head gt lt div class wrapper gt lt Header gt if currentScreen home lt Home on submit handleJoinCall gt else lt Call userName url on left handleLeaveCall gt if lt div gt Let s step through this In the script tag we start by importing the components we ll be using Call Home and Header Then we declare variables that will be used in this component but are assigned later on Next we define handleJoinCall which we ll describe in more detail below In short it sets our currentScreen variable to call We then define handleLeaveCall which simply resets currentScreen to home Lastly we import our daily js script tag to make the daily js library available to the rest of the app Now let s specifically look at the markdown in App to see how we render our components App svelte lt div class wrapper gt lt Header gt if currentScreen home lt Home on submit handleJoinCall gt else lt Call userName url on left handleLeaveCall gt if lt div gt In Svelte you can conditionally render components based on your JavaScript values using an if statement We know we always want to render our Header but we only want to render the Call component if the user is trying to join a call i e the currentScreen equals call This is where we can use Svelte s if syntax if currentScreen home to render the Home screen else we can show the Call component And don t forget to close your if block with if Listening for custom eventsAnother handy feature of Svelte is being able to dispatch custom events that can be forwarded to other components Since the Home component has a form to join calls we want to call handleJoinCall defined in App when the form s submit event is dispatched Similarly when you re in a call and go to leave the call we want to listen for the custom left event we ll define in Call We handle both situations by adding a custom listener on each component like so lt Call on left handleLeaveCall gt Notice how it says on left This will listen for any left events dispatched To listen to other custom events you ve defined you can just update the event name such as on fancy event name One other thing to note is being able to pass variables to child components In Svelte we can pass the userName and url values as props to the Call component like so lt Call userName url gt Note Since the prop name and variable being passed use the same name we can use the shorthand notation That is to say url is shorthand for url url These properties can then be made available in Call like so Call svelteexport let url export let userName Honey I m Home svelte By default App will render the Home component first Our Home component contains the main content for our app s home screen The code for it is a bit longer than App so we ll look at the most important sections Home svelte lt script gt import createEventDispatcher onMount from svelte import api from api const dispatch createEventDispatcher At the top of our component we import Svelte s createEventDispatcher method and assign it to the variable dispatch This method is what we ll use for dispatching our custom events discussed above Now let s jump to our HTML and focus on the form Home svelte lt div class home screen gt lt h gt Daily Prebuilt Svelte demo lt h gt lt p gt Start demo with a new unique room or paste in your own room URL lt p gt … lt form on submit goToCall gt lt label for name gt Name lt label gt lt input id name type text required bind value name gt lt label for url gt Daily URL lt label gt lt input id url type text required bind value url placeholder gt lt input type submit value Join call gt lt form gt lt div gt Here we have a native HTML lt form gt element with the submit handler using goToCall lt form on submit goToCall gt Note This is not a custom event since forms have a native submit event The form has two inputs for a username and Daily room URL To make each of these input values available in our component s JavaScript we can bind each value to a variable declared at the top of the component For example the username input value will be bound to the variable name which is declared at the top of the file Home svelte lt script gt let name lt script gt lt form on submit goToCall gt lt input id name type text required bind value name gt lt form gt This means when the form s submit event occurs and the goToCall method is called we can use the input values via our bound variables e g name This also makes the input values available to forward to the App component via the dispatch method we defined before like so Home svelteconst goToCall e gt e preventDefault dispatch submit name url In goToCall we first prevent the form from refreshing the page with e preventDefault Then we use our dispatch method to forward the submit event to our App component Both name and url our variables bound to the inputs are passed as options to make those values available to App as well If you recall from App the Home component has an event listener on it for submit which calls the handleJoinCall method lt Home on submit handleJoinCall gt When our dispatched submit event registers in App it will call handleJoinCall App svelte const handleJoinCall detail gt currentScreen call set component vars with form submission values url detail url userName detail name save in local storage localStorage setItem svelte prebuilt url url localStorage setItem svelte prebuilt name userName error null In handleJoinCall we update currentScreen to equal call This will cause the Call component to show instead of Home We then set our url and userName variables to the values passed from the form and save them in local storage as well Now that all the Home form s information is shared with App ーwho also shares it with Call ーwe can move on to setting up our call UI Call on line pleaseSo far we ve set up our App component and our Home screen Now let s build our Daily call in Call svelte Let s start with the Call component s HTML markdown this time Call svelte lt div class meetingState joined meeting call screen call screen prejoin gt lt div id container gt lt Controls url meetingState stats on toggle camera toggleCamera on toggle mic toggleMic on toggle screen share toggleScreenShare on fullscreen goFullscreen on toggle local video toggleLocalVideo on toggle remote video toggleRemoteVideo gt lt div gt We have a container div with two children Another div which is where we ll embed Daily PrebuiltOur Controls component which receives the room url meetingState and call stats as props It also has a list of custom event listeners added for each of the control s buttons Let s focus on the Daily call to start Embedding Daily Prebuilt in your Svelte appSvelte has a handy onMount lifecycle method that gets called when the component is first rendered Call svelteimport onMount from svelte onMount gt assume if the Call component is showing we should join initializeDaily We know the Call component mounts when the form is submitted so we want to initialize the call as soon as Call renders We can do this by calling initializeDaily on mount Call svelte const initializeDaily async gt … select container element to embed Daily iframe in const container document getElementById container create Daily iframe callFrame window DailyIframe createFrame container iframeStyle IFRAME OPTIONS showLeaveButton true url userName callFrame on joining meeting updateMeetingState callFrame on joined meeting updateMeetingState callFrame on left meeting handleLeftMeeting callFrame on error updateMeetingState set up interval for retrieving current network stats interval setInterval gt getNetworkStats let the local user join the call which will cause the call to be displayed in our app UI await callFrame join Stepping through this initializeDaily function We first select our div element that will be the Daily Prebuilt iframe s container const container document getElementById container Next we create our Daily Prebuilt iframe with the createFrame method via daily js and pass the container div and some call options to it window DailyIframe createFrame container options Recall window DailyIframe exists because we imported the daily js script in App Next we add some Daily event listeners so we can update our UI if the local user joins a call leaves or there s a critical error We ll explain this a bit more below e g callFrame on joined meeting updateMeetingState Then we set up an interval to get the call s network stats every seconds so we can display it in our Control panel We won t go into more detail about this but ask us if you need help interval setInterval gt getNetworkStats And finally we use Daily s join method to actually join the call await callFrame join Adding our custom control panelAs Bruce Springsteen once said “Honey I want the heart I want the soul I want control right now so let s do just that and add a little more control to our app daily js provides instance methods to programmatically do anything you can already do via Daily Prebuilt s UI This gives a bit more flexibility to how you want to set up your own app s UI For example if you want to add a big “Mute button to your UI you can Let s take a look at how Adding a Mute button to toggle local audioAs mentioned our Call component has a bunch of custom event listeners added to Controls This means all the actual Daily logic can stay contained in our Call component The Controls component is basically just UI to dispatch the custom events Call svelte lt Controls … on toggle mic toggleMic In Controls we have a button to mute the local user Controls svelte lt button on click handleToggleMicClick gt lt span gt Toggle mic lt img src images mic svg alt Microphone gt lt span gt lt button gt On click this button calls handleToggleMicClick That method will then dispatch our toggle mic custom event const handleToggleMicClick gt dispatch toggle mic Looping back to Call the toggle mic custom event that is forwarded calls toggleMic on toggle mic toggleMic a method defined in Call The toggleMic method is what contains our daily js interaction Call svelte const toggleMic gt if callFrame logError noCallFrameError return const localVideo callFrame localAudio callFrame setLocalAudio localVideo If there is no Daily callFrame defined in initializeDaily we do nothing This shouldn t ever happen but you know bugs Next we get our current local audio state muted or unmuted via the localAudio Daily method const localVideo callFrame localAudio Whatever the current value is we want to make it the opposite To do this we can use the setLocalAudio instance method and set our local audio to the inverse boolean value callFrame setLocalAudio localVideo Once that s called your unmuted audio will mute or vice versa We won t cover all the buttons in the control panel since they all follow a similar pattern but if you need help please let us know Appetite for call destructionTo understand how the Daily event listeners work a bit more let s use the left meeting event as an example In Call we added an event listener for left meeting which calls a callback method handleLeftMeeting when triggered Call sveltecallFrame on left meeting handleLeftMeeting in initializeDaily const handleLeftMeeting e gt updateMeetingState e if interval clearInterval interval dispatch left The callback handleLeftMeeting gets called when the local user clicks the Leave button via Daily Prebuilt s UI It then dispatches a custom event left that App is listening for It does a couple other clean up tasks as well but we won t worry about that for now Essentially it resets our app s state If you recall App has a listener on the Call component for a custom left event lt Call userName url on left handleLeaveCall gt handleLeaveCall gets called which resets our currentScreen value to home const handleLeaveCall gt currentScreen home Once currentScreen gets reset to home App will render the Home component instead of Call We ve come full circle back home Cleaning up after the partyNow that we have reset our state to get back to the home screen we still have a little leftover clean up to do If you recall we added some Daily event listeners to our callFrame As a final step we can turn off those event listeners and destroy our Daily callFrame It will be recreated when the next call is joined so we don t need it hanging around after leaving this call Call svelteimport onDestroy from svelte onDestroy gt if callFrame remove event listeners callFrame off joining meeting updateMeetingState callFrame off joined meeting updateMeetingState callFrame off left meeting handleLeftMeeting callFrame off error handleError destroy Daily callframe after call ends callFrame destroy Svelte provides an onDestroy lifecycle method that will be triggered when the Call component is destroyed In onDestroy we can turn off our Daily event listeners and destroy the callFrame with Daily s destroy method Wrapping upWe hope this tutorial helps you get started with building your own Daily video apps in Svelte To learn
