Caching API Responses in PokedexCLI: Reducing Network Work in Go

One of the easiest performance problems to overlook in an API-driven application is repeated work.

If an application repeatedly requests the same resource from a remote service, every request introduces network latency and another dependency on the availability of that service.

PokedexCLI provides a useful environment for exploring this problem because the application repeatedly interacts with the Pokémon API while the user navigates locations and explores areas.

Designing a CLI Architecture for PokedexCLI in Go

Building a command-line application can look deceptively simple.

At first, the requirements for PokedexCLI seem straightforward: accept a command, execute it, call the Pokémon API when necessary, and print the result.

But even a small CLI becomes difficult to maintain when command handling, application state, networking, caching, and presentation logic are allowed to grow together.

For PokedexCLI, I wanted to approach the problem as a real software-engineering exercise rather than simply building a collection of commands that happened to work.
