海外TECH	DEV Community	#refineweek: Adding Realtime Collaboration	https://dev.to/refine/refineweek-adding-realtime-collaboration-23k8	refineweek Adding Realtime CollaborationIn this post we implement realtime broadcast and subscription of pixels updates in our refine based Pixels app We do this with the liveProvider prop on lt Refine gt and Supabase s Realtime servers Applying a PubSub feature allows us to receive instant updates in one part of our app for database changes triggered from another part or by a different client Here s a quick rundown of the features we ll work on Allow multiple users to draw pixels on a canvas All contributors can see realtime updates on the canvas This is Day in the series titled refineWeek refineWeek is a quickfire tutorial guide that aims to help developers learn the ins and outs of refine s powerful capabilities and get going with refine within a week refineWeek seriesDay Pilot amp refine architectureDay Setting Up the Client App OverviewOn Day Three we implemented CRUD operations using Supabase dataProvider methods and the resources prop which leveraged RESTful routes in the routerProvider object under the hood Today we are going to explore the liveProvider prop as we implement realtime collaboration on a canvas so that pixels drawn on a canvas by one user is instantly seen by anyone else viewing it from another client There are two parts to our endeavor in this post one in the Supabase backend and one in our refine app Spin up Realtime servers from Supabase dashboard for the resource we want to publish changes for and subscribe to Registering the liveProvider prop inside lt Refine gt component and enabling subscription with liveMode auto refine has already added the implementation code for Supabase Realtime provider in the liveProvider object it created for us during project initialization We will mostly play the laymen role here as we tour around the underlying principles and the magic at work behind the scenes Let s start by first making sure Realtime servers are set up for the pixels table in the Supabase backend Setting Up Supabase RealtimeIn order to make drawing collaborative between our users we have to run Supabase Realtime servers and create channels for our pixels resource We can do this from the Supabase dashboard for the database we created If you haven t already please go ahead and select Enable Realtime for the pixels table from its editor Behind the scenes Supabase spins up globally distributed Realtime servers that facilitate low latency communication between our app and Supabase database tables Supabase s Realtime feature spares a channel for each resource to be broadcasted Any change in the resource is published in the channel and clients that subscribe to the channel receive updates as soon as the change is made We are using Supabase Realtime s PostgreSQL Change Data Capture feature which will now allow our app to publish mutation events to the pixels channel and also listen to those changes from a subscriber component This means mutation hooks such as useCreate can now publish events to the pixels channel and consumer hooks like useList are able to get instant updates for any change to pixels lt Refine gt s liveProvider PropNow it s time to move our attention back to the lt Refine gt component in our app We already have the liveProvider prop passed in with the liveProvider function from pankod refine supabase App tsx lt Refine liveProvider liveProvider supabaseClient gt And that s it The channel for pixels resource that was specified above in Supabase will broadcast all mutations on the pixels table And any subscriber will be able to receive real time updates about the changes Now let s try opening the app in two browsers one with Google account and one with GitHub Navigate to a canvas page the same one in both and try adding some pixels from each We ll see that pixels created in one are displayed in the other in real time This is obnoxious because we don t know how this is happening And very pleasant because create refine app already generated the code that handles the PubSub logic for Supabase PostregSQL CDC Let s have a look to see what s happening in the Supabase liveProvider object refine s Supabase liveProvider Objectrefine s liveProvider object has the following signature const liveProvider subscribe channel params ids types callback gt any unsubscribe subscription gt void publish event gt void In pankod refine supabase version at the time of publishing this article the liveProvider consists of only the subscribe and unsubscribe methods Its implementation looks like this Supabase data providerconst liveProvider supabaseClient SupabaseClient LiveProvider gt return subscribe channel types params callback object RealtimeSubscription gt const resource channel replace resources const listener payload SupabaseRealtimePayload lt any gt gt if types includes types includes liveTypes payload eventType if liveTypes payload eventType created amp amp params ids undefined amp amp payload new id undefined if params ids map String includes payload new id toString callback channel type liveTypes payload eventType date new Date payload commit timestamp payload payload new else callback channel type liveTypes payload eventType date new Date payload commit timestamp payload payload new const client supabaseClient from resource on supabaseTypes types listener types slice map item gt client on supabaseTypes item listener return client subscribe unsubscribe async subscription RealtimeSubscription gt supabaseClient removeSubscription subscription Both methods are concerned with subscription to the changes That s because the publishing the event is done by mutation methods In our case it is done from the useCreate hook we invoke to create a pixel Let s have a look BroadcastingIf we look inside our lt CanvasShow gt component that is rendered at canvases id we have a lt CanvasItem gt component which basically displays all pixels that belong to the canvas item being visited lt CanvasItem gt is also the component from where a pixel is created so let s look at that now src pages components canvas item tsximport React from react import Typography from pankod refine antd import Pixel Canvas from types import DEFAULT SCALE PIXEL SIZE from utility constants const Text Typography type CanvasItemProps canvas Canvas pixels Pixel scale number border boolean active boolean onPixelClick x number y number gt void export const CanvasItem React FC lt CanvasItemProps gt canvas id name width height pixels scale DEFAULT SCALE border true active true onPixelClick gt return lt div gt Array from length height map i gt lt div key row i style display flex gt Array from length width map j gt lt div key row i col j gt lt div onClick gt if onPixelClick amp amp active onPixelClick j i style cursor active pointer undefined width PIXEL SIZE scale height PIXEL SIZE scale border border px solid rgba undefined background pixels find el gt el x j amp amp el y i color transparent gt lt div gt lt div gt active amp amp lt Text className canvas name text gt name id lt Text gt lt div gt The most relevant thing to look in the component above is the onPixelClick click event handler It is a prop received by the lt CanvasItem gt from the lt CanvasShow gt component It s original value is the onSubmit function defined inside the lt CanvasShow gt component We d like to focus on this onSubmit event handler because it is what facilitates the creation of a pixel src pages canvases show tsxconst mutate useCreate const onSubmit x number y number gt if identity return push login if typeof x number amp amp typeof y number amp amp canvas id mutate resource pixels values x y color canvas id canvas id user id identity id successNotification false As we can see with the call to mutate method of the useCreate hook a new entry is being added to the pixels table upon every click on the canvas And since we enabled realtime for the pixels table each successful create action broadcasts the change to the pixels channel for subscribers to pick refine usePublish HookThe exact way it happens looks like this useCreate hook is called from the consumer component useCreate behind the scenes uses the live usePublish hook to publish the created event to the pixels channel on Supabase Realtime servers The published event for pixels create action produces an object with the following signature channel resources pixels type created payload ids id of created pixel date new Date Feel free to go through the live hooks docs for details about how live publishing is supported by useCreate and other mutation hooks SubscriptionThe changes to the pixels table can be subscribed by consumer components with the useList hook We are showing the pixels inside the lt CanvasShow gt component itself but they are fetched inside the lt DisplayCanvas gt render props component The useList hook inside lt DisplayCanvas gt looks like this src components canvas display tsxconst data useList lt Pixel gt resource pixels liveMode auto config filters field canvas id operator eq value id sort field created at order desc hasPagination false metaData select users id full name avatar url Among the loads of arguments and options passed to the useList hook we have used the liveMode auto property which allows us to subscribe to the Realtime channel for the pixels resource With liveProvider disabled in the lt Refine gt component useList acts as a normal dataProvider hook With liveProvider activated under the hood useList banks on refine s useResourceSubscription live hook to communicate with the pixels channel refine useResourceSubscription HookThe actual subscription is done by the liveProvider subscribe method The subscribe method is called from inside the useResourceSubscription hook in order to subsribe to the pixels channel If you want to dive into the details please feel free to do so in the liveProvider docs here SummaryIn today s part we implemented real time collaboration for drawing pixels on canvas items using lt Refine gt component s liveProvider prop and its supporting hooks for publishing and subscribing to Supabase s Realtime servers The subscribe method on Supabase s liveProvider object allows us to subscribe to a channel created for a resource Subscription for the resource is triggered by the useResourceSubscription hook called from data hooks that support live subscription the useList hook in our example Broadcasting in turn is initiated by the usePublish hook called from a supported mutation hook for our resource the useCreate hook in this case We implemented real time collaboration very effortlessly due to the out of box solutions provided by refine s pankod refine supabase package With this now we have enabled multiple users to draw on a canvas at the same time and receive updates instantly	2023-02-17 08:37:35
