Listener

The Flatfile Listener is a core building block of the Flatfile platform. Listening and responding to events is what enables developers to build powerful integrations with Flatfile. This package enables you to handle all the events in your data pipeline — from the moment data arrives to its final transformation. Think of it as your event command center.

​

Basic Usage

import { Listener } from "@flatfile/listener";

export default (listener: Listener) => {
  listener.on("**", (event) => {
    console.log(event);
  });
};
