In this series we will tackle the problem of optimizing network access to fetch data from the network, a common theme of networked applications. While it is certainly trivial to fetch data from a server in any modern framework or OS, optimizing the frequency of access to the network, in order to save bandwidth, battery, user frustration, amongst other things, is complex. More so if you want to reduce code duplication, ensure testability, and leave something useful (and comprehensible) for the next engineer to use.
To justify my claim, let me start by sharing my personal history in the dev world… divided by programming languages.
