live update socket

Hello everyone, how to implement liveProvider and live update if I use socket.io, since I didn't find a specific example in refine, and how should it look on the backend if I use nodejs express. I would also like to see an example from Sider showing the number of new updates along with this

Hi @RomaY. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. The information extracts provided do not contain specific examples or instructions on how to implement liveProvider and live updates using socket.io with a Node.js Express backend. However, refine does support real-time updates via the liveProvider prop. This feature allows you to add real-time support to your app and can be used to update and show data in real-time throughout your app. Refine remains agnostic in its API to allow different solutions to be integrated, including socket.io. A liveProvider must include the following methods:

const liveProvider = {  
 subscribe: ({ channel, params: { ids }, types, callback }) => any,  
 unsubscribe: (subscription) => void,  
 publish?: (event) => void,  
};

const liveProvider = {  
 subscribe: ({ channel, params: { ids }, types, callback }) => any,  
 unsubscribe: (subscription) => void,  
 publish?: (event) => void,  
};

Refine uses these methods in useSubscription and usePublish hooks. When the useUpdate mutation runs successfully, it will call the publish method from liveProvider with some parameters such as channel, type etc. It is useful when you want to publish the changes to the subscribers on the client side. Similarly, when useSelect hook is mounted, it will call the subscribe method from the liveProvider with some parameters such as channel, resource etc. It is useful when you want to subscribe to the live updates. For more detailed information, you can refer to the liveProvider documentation (https://refine.dev/docs/api-reference/core/providers/live-provider/). As for the Sider example showing the number of new updates, the information extracts do not provide any specific examples or instructions. I recommend checking out the refine documentation (https://refine.dev/docs) for more detailed information and examples. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I would like to see an example from socket.io

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry, but the information extracts provided do not contain specific examples or instructions on how to implement liveProvider with socket.io in refine. Refine does support real-time updates via the liveProvider prop and it allows different solutions like socket.io to be integrated. However, the specific implementation details or examples for socket.io are not provided in the extracts.

@contributor @kapa.ai I know how to do a regular live update with a socket. But I would like to learn how to make it with liveProvider from refine. Should it be done as a normal socket.io, without liveProvider from refine

Let me check the knowledge base for you. One moment! :books: ---------------------- The liveProvider in refine is designed to enable real-time updates in your application. It's an abstraction that allows you to integrate any real-time library or tool, including socket.io. Here's the basic structure of a liveProvider:

const liveProvider = {  
 subscribe: ({ channel, params: { ids }, types, callback }) => any,  
 unsubscribe: (subscription) => void,  
 publish?: (event) => void,  
};

const liveProvider = {  
 subscribe: ({ channel, params: { ids }, types, callback }) => any,  
 unsubscribe: (subscription) => void,  
 publish?: (event) => void,  
};

The subscribe method is used to subscribe to updates, unsubscribe is used to unsubscribe from updates, and publish is used to publish an event to the channel on the client side. When using hooks like useCreate, useList, useOne, useMany, useCreateMany, useInfiniteList, and useDeleteMany, refine will automatically call the publish or subscribe methods from the liveProvider when the hook is mounted or a mutation runs successfully. This allows you to easily integrate real-time updates into your application. While you can certainly use socket.io without the liveProvider, using the liveProvider allows you to leverage refine's built-in real-time functionality and potentially simplify your code. Unfortunately, the information extracts provided do not contain specific examples or instructions on how to implement liveProvider with socket.io in refine. For more detailed information and examples, I recommend checking out the refine documentation (https://refine.dev/docs) or the socket.io documentation (https://socket.io/docs/v4). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@contributor @kapa.ai But I would still like to receive an example of implementation, both on the frontend and on the backend (nodejs express socket.io)

Hey @RomaY, Sorry, we don't have an example with socket.io at the moment. But the liveProvider logic is quite simple. For example; when you call useTable, it sends some parameters like channelName, resourceName, callback etc. to the liveProvider and expects you to listen to these parameters and call the callback parameter when necessary. At this point you need to create a subscription that will listen to the parameters related to socket.io. On the backend side, you should trigger this subscription when there is a change on the related resource. That's it! I hope it helps.

@salihozdemir Thank you very much for the answer, but could you give a small example of this with socket.io and nodejs (to better understand how it works)? I would really appreciate it! @contributor
