What you'll learn in this Go course

A REPL, or Read-Eval-Print Loop, is a simple interactive programming environment that takes user input, evaluates it, and returns the result to the user. In this guided project, you'll build a Pokedex-like REPL in Go that uses the PokeAPI to fetch data about Pokemon. It's a great way to put your Go knowledge to the test and learn valuable skills like HTTP networking and data serialization.

Chapter List

1
REPL
A REPL (Read, Eval, Print Loop) is a simple interactive programming environment that takes user inputs, evaluates them, and returns the results. Learn how to implement one from scratch in Go.
2
Cache
When making network requests, one of the most common performance optimizations is to cache the results. Implement an in-memory cache for the PokeAPI in Go.
3
Pokedex
Bring your REPL and cache together to complete your fully functional Pokedex CLI.

Enjoyed the project - know nothing about pokemon but using api and go was great. Getting the cli to work was frustrating but a great learning experience.

There were some challenges, but VERY useful insights to skills that will be needed for upcoming projects I have in mind.

Not a lot of hand-holding, you have to go search yourself, but as tasks moved forward I found myself referencing docs way less often. The resulting project stops at a pretty basic pokedex ( of course) but there are great suggestions to ramp up the difficulty and grow it.
