Node.js ETL (Extract, Transform, Load) Pipeline: What Are We Building?
See the written version of this tutorial, links to prerequisites, and related tutorials:
https://heynode.com/tutorial/etl-pipe...
We're going to learn about using Extract, Transform, Load pipelines for handling large datasets with Node.js. We will use two different approaches to creating an ETL pipeline:
1. Basic ETL pipeline that retrieves all the relevant data at once from a remote data source.
2. ETL pipeline that uses Node.js Streams to process data from a local CSV file of any size.
Along the way you will learn about the different stages of an ETL pipeline, how to use Promises and async/await in Node.js, how to interact with the file system using the fs module, and how to use Streams.
