fs.ReadStream.prependOnceListener

prependOnceListener<K extends symbol | 'close' | 'error' | 'data' | 'end' | 'pause' | 'readable' | 'resume' | string & {} | 'open' | 'ready'>(

event: K,

listener: ReadStreamEvents[K]

): this;

Adds a one-timelistener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

server.prependOnceListener('connection', (stream) => {
  console.log('Ah, we have our first user!');
});

Returns a reference to the EventEmitter, so that calls can be chained.
