Handling engine events

Event handlers are set by on(event: EventKind | string, func) and fired on:

LoginSuccess successful login
LoginFailed login failure
LoginOTPRequired OTP code is required for login
LoginOTPInvalid OTP code is provided but invalid
LoginOTPSetup OTP setup is required, the parameter contains OTP secret
WsEvent WebSocket event. If handler return false, event is skipped by engine.
ServerReload server asked clients to reload UI
ServerRestart server is being restarted
HeartbeatSuccess successful heartbeat
HeartbeatError heartbeat error (default: eva.restart)
LogRecord new log record to toss
LogPostprocess log processing is finished (e.g. scroll viewer down)

The following events are handled using a string-type event kind:

Each event can have only one handler.

Example:

import { EventKind } from "@eva-ics/webengine";

eva.on(EventKind.LoginSuccess, () => {
  // hide the login window and display UI page
});
