Parser

A parser turns its input (often text in form of a file) into a more advantageous representation (usually a certain data structure in memory) to perform a specific task.

Common examples include:

https://github.com/bsnext/fastify-bowser

A plugin for Fastify that adds the 'request.useragent' property to get header 'user-agent' parsed data.
