Web Servers lesson 13

Web course is complete!

The thirteenth and final lesson of the Web Servers courseIn case you haven’t been following along: Web servers, at a low level is a 13-part course that explains the HTTP protocol and covers a variety of intermediate Haskell topics while we build a server from nearly scratch. is out today! The HTTP server that we’ve been developing throughout this course is a great application for a streaming library, so in this lesson we take the opportunity to introduce pipes.

We hadn’t written anything about streaming yet because it is difficult to explain purpose of a streaming library, in the abstract, without grounding in some motivating example. The subject of this course serves as a perfect motivating example, and the server comes together very nicely using only a handful of basic pipe operations.
