Building a Reliable REST API Client in Go for PokedexCLI

A command-line application becomes considerably more interesting when it has to communicate with a remote service.

PokedexCLI does not contain all of its data locally. Much of the information the application needs comes from the Pokémon API, which means the application has to deal with HTTP requests, JSON responses, network failures, pagination, and external service boundaries.

Rather than allowing every command to construct its own HTTP requests, I treated API communication as a dedicated responsibility.

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.
