API reference / @chanx-js/client / core / defineChannel

Function: defineChannel()

function defineChannel<ToServer, ToClient, Replies>(): <Address, Topics>(spec) => ChannelDescriptor<ToServer, ToClient, Address, Topics, Replies>;

Defined in: packages/client/src/core/descriptor.ts:124

Declare a channel.

Curried so the message types can be given explicitly while the address literal and topic map are still inferred: TypeScript has no partial type-argument inference.

export const chat = defineChannel<ChatToServer, ChatToClient, ChatReplies>()({
  name: 'chat',
  address: '/ws/chat/{room}/',
});

Type Parameters

Type Parameter	Default type
ToServer extends ChanxMessage	-

Returns

<Address, Topics>(spec) => ChannelDescriptor<ToServer, ToClient, Address, Topics, Replies>
