poll-server-check/types/poll-server-check.d.ts

An npm package that checks if the server is running or if it's down. If the server is down, it repeatedly sends a check API to the backend to wake it up and displays toast notification of the current status.

declare module "poll-server-check" {
  export function clientCheck(BackendUrl: string): void;
  export function serverCheck(app: any): void;
}
