Stream to an HTTP Response with Node.js

In this tutorial we will use streams to efficiently send a large file as an HTTP response in a Node.js application. Reading a large file into memory before sending it back as a response is an inefficient use of time and resources. We can create a readstream from a file and pipe it directly to an HTTP response body, significantly reducing the memory footprint and time required to serve the file.

By the end of this tutorial, you should be able to:

• Understand streaming to a response body
• Implement fs.createReadStream and pipe the content into an HTTP response
