海外TECH	DEV Community	Create a Video Party App With Rails Part 2: Building the Frontend	https://dev.to/vonagedev/create-a-video-party-app-with-rails-part-2-building-the-frontend-hfe	Create a Video Party App With Rails Part Building the FrontendThis is the second part of a two part series on creating a video watch party application using the Vonage Video API and Ruby on Rails In the first article we went through the steps of building the backend of the app If you have not read that post yet it would be a good place to start Now we are going to focus on the frontend of our application While the backend was written mainly in Ruby the frontend will be a lot of client side JavaScript Once we are done we will have a video watch party app that we can use to chat with our friends and watch videos together Let s get started tl dr If you would like to skip ahead and get right to deploying it you can find all the code for the app and a one click Deploy to Heroku button at the GitHub repository Table of ContentsWhat Will We Be BuildingCreating the JavaScript PacksStyling the ApplicationPutting It All TogetherWhat Will We Be BuildingBefore we start coding it is a good idea to take a moment and discuss what we will be building If you recall from the first post we had instantiated a Video API Session ID and are actively creating tokens for each participant That information is being passed to the frontend by newly created JavaScript variables in the ERB view files Additionally we are also passing data from our environment variables to the frontend We will be using all that information in the code we will write to create the experience of the app Ruby on Rails has come a long way in integrating client side JavaScript directly into the stack with the introduction of Webpack in Rails starting with version JavaScript is incorporated through packs placed inside app javascript packs and added as either import or require statements inside the application js file inside the directory We will be separating out the various concerns of our code into different files so that at the end your folder will have the following files app javascript packs application js app helpers js chat js opentok screenshare js opentok video js party js screenshare jsEach file besides application js will contain code to cover distinct concerns app helpers js Cross functional code that is needed across the frontendchat js Creating a Chat class that will be used to instantiate instances of the text chatopentok screenshare js The client side code for the Screenshare viewopentok video js The client side code for the Video Chat viewparty js Creating a Party class that will be used to instantiate instances of the video chatscreenshare js Creating a Screenshare class that will be used to instantiate instances of the screenshare functionalityPrior to creating the code let s add these files to the application js file which will instruct Webpack to compile them at runtime application jsimport app helpers js import opentok video js import opentok screenshare js Creating the JavaScript PacksIn each subsection we will create the JavaScript files that we enumerated above The app helpers js FileThe app helpers js file will contain generic helper functions that we will export to the rest of the code to use throughout the app We will create screenshareMode setButtonDisplay formatChatMsg and streamLayout functions The screenshareMode function will take advantage of the Vonage Video API Signal API to send a message to the browsers of all the participants that will trigger a window location change The Signal API is the same API we will use for the text chat which is its simplest use case However as we will see in this function the Signal API provides an intuitive and powerful way to direct the flow of your application simultaneously for all the participants without needing to write lots of code export function screenshareMode session mode if mode on window location screenshare name name session signal type screenshare data on else if mode off window location party name name session signal type screenshare data off The next function setButtonDisplay changes the style for the HTML element containing the Watch Mode On Off button to either be block or none depending on whether the participant is the moderator or not There are many other ways to do this including more secure methods However in order to keep things simple for this app to watch videos amongst friends we will keep the keep minimalist export function setButtonDisplay element if name moderator env name element style display block else element style display none The formatChatMsg function takes in the text message the participant sent as an argument and formats it for presentation on the site This function looks for any text bracketed by two colons and attempts to parse the text inside those colons as an emoji It also appends the participant s name to each message so everyone knows who is talking In order to add the emojis we need to install a node package called node emoji and we can do that by adding const emoji require node emoji to the top of the file and running yarn add node emoji in the command line The function will utilize match with a regular expression to search for strings of text bookmarked by two colons and if it matches it will invoke the emoji const we defined to turn that string into an emoji export function formatChatMsg message var message arr message arr message split map function word if word match b w b g return word emoji get word else return word message message arr join return name message The last function inside app helpers js we need to create is streamLayout that takes in arguments of the HTML element and the count of participants The function will add or remove CSS classes to the element depending on the number of participants in order to change the video chat presentation into a grid format export function streamLayout element count if count gt element classList add grid else if count element classList remove grid element classList add grid else if count lt element classList remove grid The chat js FileThe chat js code is going to create the Chat class using a constructor This Chat class will be called and instantiated in both the video chat and screenshare views chat jsimport formatChatMsg from app helpers js export default class Chat constructor session this session session this form document querySelector form this msgTxt document querySelector message this msgHistory document querySelector history this chatWindow document querySelector chat this showChatBtn document querySelector showChat this closeChatBtn document querySelector closeChat this setupEventListeners We have given several properties to Chat mostly based on different elemnts in the DOM and the Video API session The last one this setupEventListeners is invoking a function that we need to now add to the file setupEventListeners let self this this form addEventListener submit function event event preventDefault self session signal type msg data formatChatMsg self msgTxt value function error if error console log Error sending signal error name error message else self msgTxt value this session on signal msg function signalCallback event var msg document createElement p msg

function event self chatWindow classList add active this closeChatBtn addEventListener click function event self chatWindow classList remove active setupEventListeners creates an EventListener for the text chat submit button When a new message is submitted it is sent to the Signal API to be processed and sent to all the participants Similarly when a new message is received a new lt p gt tag is added to the chat element and the participant s text chat window is scrolled to view it The next two files we will create perform similar functionality in creating new classes for the video chat party and for the screenshare view The party js FileIn this file we will create the Party class that will be used to instantiate new instances of the video chat party jsimport screenshareMode setButtonDisplay streamLayout from app helpers js export default class Party constructor session this session session this watchLink document getElementById watch mode this subscribers document getElementById subscribers this participantCount document getElementById participant count this videoPublisher this setupVideoPublisher this clickStatus off this setupEventHandlers this connectionCount setButtonDisplay this watchLink The constructor function is given the Video API session as an argument and passes that to this session The rest of the properties are defined and given values The watchLink subscribers participantCount properties come from the HTML elements while videoPublisher is provided a function as its value and clickStatus is given default of off We will create the setupVideoPublisher function at this point The function invokes the Video API JavaScript SDK initPublisher function to start the video publishing It can take in optional arguments and as such we specify that the video should occupy of the width and height of its element and should be appended to the element setupVideoPublisher return OT initPublisher publisher insertMode append width height function error if error console error Failed to initialise publisher error There are several actions we also must create event listeners for and add them to the class We need to listen for when the session is connected when a video stream has been created when a connction has been added and when a connection has been destroyed When a connection has been added or destroyed we either increment or decrement the participant count and share the number of participants in the participant count lt div gt element on the page setupEventHandlers let self this this session on This function runs when session connect asynchronously completes sessionConnected function event Publish the publisher we initialzed earlier this will trigger streamCreated on other clients self session publish self videoPublisher function error if error console error Failed to publish error This function runs when another client publishes a stream eg session publish streamCreated function event Subscribe to the stream that caused this event and place it into the element with id subscribers self session subscribe event stream subscribers insertMode append width height function error if error console error Failed to subscribe error This function runs whenever a client connects to a session connectionCreated function event self connectionCount self participantCount textContent self connectionCount Participants streamLayout self subscribers self connectionCount This function runs whenever a client disconnects from the session connectionDestroyed function event self connectionCount self participantCount textContent self connectionCount Participants streamLayout self subscribers self connectionCount Lastly we add one more event listener This event listener is attached to the click action on the Watch Mode On Off button When it is clicked it goes to the screenshare view if the click status was off You will recall that the click status is given a default of off in the construction of the class this watchLink addEventListener click function event event preventDefault if self clickStatus off Go to screenshare view screenshareMode self session on The screenshare js FileThe final class we will create is a Screenshare class that will be responsible for defining the video screenshare The constructor function takes the Video API session and the participant s name as arguments screenshare jsimport screenshareMode from app helpers js export default class Screenshare constructor session name this session session this name name this watchLink document getElementById watch mode this clickStatus on Unlike the Party class the clickStatus here defaults to on since we want to move away from the screenshare and back to the video chat mode if the moderator clicks the Watch Mode On Off button We also utilize toggle to either share the participant s screen if the participant is the moderator or subscribe to the screenshare for everyone else toggle if this name moderator env name this shareScreen else this subscribe The shareScreen function invoked in the toggle needs to be defined shareScreen this setupPublisher this setupAudioPublisher this setupClickStatus This function itself has three functions that need to also be created The first function will publish the screen of the moderator However the screen publishing by itself does not also include audio Therefore a second function will publish the audio from the moderator s computer Then the final function in shareScreen will move back to the video chat view if the Watch Mode On Off button is clicked setupClickStatus screen share mode off if clicked off Set click status let self this this watchLink addEventListener click function event event preventDefault if self clickStatus on self clickStatus off screenshareMode self session off setupAudioPublisher var self this var audioPublishOptions audioPublishOptions insertMode append audioPublishOptions publishVideo false var audio publisher OT initPublisher audio audioPublishOptions function error if error console log error else self session publish audio publisher function error if error console log error setupPublisher var self this var publishOptions publishOptions videoSource screen publishOptions insertMode append publishOptions height publishOptions width var screen publisher OT initPublisher screenshare publishOptions function error if error console log error else self session publish screen publisher function error if error console log error All the above is in order to create the screenshare for the moderator Everyone else in the app will want to subscribe to that screenshare We will use the subscribe function to do that This will be the last function inside the file subscribe var self this this watchLink style display none this session on streamCreated function event console log event if event stream hasVideo true self session subscribe event stream screenshare insertMode append width height function error if error console error Failed to subscribe to video feed error else if event stream hasVideo false self session subscribe event stream audio insertMode append width px height px function error if error console error Failed to subscribe to audio feed error We are now ready to make all these classes we have defined work in the application by creating instances of them inside the opentok screenshare js and opentok video js files Creating opentok video jsThe opentok video js file will build a new video chat experience Most of the work was done in the classes we defined above so this file is relatively small First let s import the Chat and Party classes opentok video jsimport Chat from chat js import Party from party js Then we will define a global empty variable to hold the Video API session var session Then we wrap the rest of the code in three checks to make sure we are on the correct website path that the DOM is fully loaded and that the participant name is not empty if window location pathname party document addEventListener DOMContentLoaded function if name The rest of the code initiates a new Video API session if one does not exist and instantiates a new Chat and new Party At the end we also listen for the Signal API to send a screenshare data message with the value of on When that message is received the window location is moved to screenshare Initialize an OpenTok Session object if session session OT initSession api key session id new Chat session new Party session Connect to the Session using a token session connect token function error if error console error Failed to connect error Listen for Signal screenshare message session on signal screenshare function screenshareCallback event if event data on window location screenshare name name Creating opentok screenshare jsThe last JavaScript file we will create is mightily similar to the last one It is responsible for the screenshare view and leverages the Screenshare and Chat classes we defined earlier import Screenshare from screenshare js import Chat from chat js declare empty global session variablevar session if window location pathname screenshare document addEventListener DOMContentLoaded function Initialize an OpenTok Session object if session session OT initSession api key session id Hide or show watch party link based on participant if name amp amp window location pathname screenshare new Chat session new Screenshare session name toggle Connect to the Session using a token session connect token function error if error console error Failed to connect error Listen for Signal screenshare message session on signal screenshare function screenshareCallback event if event data off window location party name name Before we can wrap this up last but certainly not least we need to define the frontend style of the application All this code is useless if it is not accessible by the participants Styling the ApplicationThe stylesheet for this application would not have happened without the help of my friend and former colleague Hui Jing Chen who taught me a lot about front end design through this process The app primarily uses Flexbox Grid to order the elements Let s start by creating a custom css file inside app javascript stylesheets We want to make sure that it is included in our application so add an import line to application scss in the same folder import custom css First let s add the core styling in custom css root main a txt alt white txt black background white bgImage url images png chat bg rgba chat mine darkgreen chat

TogetherEven though the application is a combination of multiple programming languages namely Ruby and JavaScript with an intertwined backend and frontend it is relatively straightforward to run it This is because Rails allows us to seamlessly integrate it all together with one command From the command line you can execute bundle exec rails s and watch your Rails server start You will also see the following almost magical line in your console output the first time you run the app Webpacker Compiling In fact you will see that every time you make a change to any of your JavaScript or CSS packs That output tells you that Rails is using Webpack to compile and incorporate all of your packs into the application Once the Webpacker Compiling is done you will see a list of all your compiled packs Version webpack Time msBuilt at PM Asset Size Chunks Chunk Names js app helpers cd js KiB app helpers emitted immutable app helpers js app helpers cd js map KiB app helpers emitted dev app

if you look closely like opentok screenshare party app helpers etc Running your application locally is great for testing with yourself but you probably would like to invite friends to participate with you You can create an externally accessible link to your application running locally using a tool like ngrok It gives an external URL for your local environment The Nexmo Developer Platform has a guide on getting up and running with ngrok that you can follow If you would like to just get up and running you can also deploy with one click this application from GitHub directly to Heroku Click on the button and within moments you will have a watch party app ready to be used and enjoyed I would love to hear what you built using the Vonage Video API Please join the conversation on our Community
