Just as socket.emit on the client, socket.broadcast.emit on the server takes in an event name and an optional payload.

Sets a modifier for a subsequent event emission that the event will only be broadcasted to sockets that have joined the given room. Each namespace emits a connection event that receives each Socket instance as a parameter. It can include custom query string parameters if required by the server. While using the REST API and just listening to real-time events on a socket is possible, Feathers also allows to call service methods through a websocket which, in most cases will be faster than REST HTTP. socket.id gives the unique id for the socket (client), you can store it in many ways.

When you set store parameter in installation, `Vue-Socket.io` will start sending events to Vuex store. The reason to use this… Parameters: body – A query to restrict the results specified with the Query DSL (optional); index – A comma-separated list of indices to restrict the results; doc_type – A comma-separated list of types to restrict the results; allow_no_indices – Whether to ignore if a wildcard indices expression resolves into no concrete indices. Adds the socket to the room, and fires optionally a callback fn with err signature (if any). JSDoc. HAProxy's configuration process involves 3 major sources of parameters : - the arguments from the command-line, which always take precedence - the "global" section, which sets process-wide parameters - the proxies sections which can take form of "defaults", "listen", "frontend" and "backend". The mechanics of joining rooms are handled by the Adapter that has been configured (see Server#adapter above), defaulting to socket.io-adapter. Additional headers can be specified via the first input of the SocketIO DAT. But Socket.IO is not a WebSocket implementation, it uses WebSocket transport whenever possible, it adds some metadata to each packet: the packet type, the namespace and the packet id when a message acknowledgement is needed. The kind and apiVersion identify the CRD of which the custom resource is an instance.. A label, applicable only to KafkaTopic and KafkaUser resources, that defines the name of the Kafka cluster (which is same as the name of the Kafka resource) to which a topic or user belongs.. Clients are created through a SocketManager, which owns the SocketEngineSpec that controls the connection to the server.. For example: // Create a socket for the /swift namespace let socket = manager. Parameters: app – The flask application instance. This input should be in a table format with two columns, structured as name/value pairs. If ‘ mem ’ and ‘ memdev ’ are omitted in all nodes, RAM is split equally between them.
