Methods

connect

connect(): Promise<Required<Connection>>
Returns the promise that is resolved when a connection becomes available. Usually, you don't have to call this method manually, since the connection would be established automatically as soon as the first request is sent or the first listener is subscribed.

Returns Promise<Required<Connection>>

getConnection

getConnection(): null | Required<Connection>
Returns the established connection, or null if it isn't available. Use connect to establish a connection.

Returns null | Required<Connection>

isSupported

Returns true if an event of the given type is supported, or false otherwise.

Parameters

requestAsync

requestAsync(event): Promise<Event>
