JsonRpcProvider
to connect to a chain via a WebSocket.
function WebSocketProvider(
uri: string,
protocols?: string | string[],
): JsonRpcProvider
This package doesn't have any export on the root. Instead it has 2 subpaths, each for a different environment.
For web runtimes, where the browser's WebSocket
constructor can be used, import WebSocketProvider
from @polkadot-api/ws-provider/web
.
For other runtimes where the WebSocket
from the module ws
should be used instead, import WebSocketProvider
from @polkadot-api/ws-provider/node
.
