Build a Pokedex in Go

Build a command-line Pokedex with a REPL, API calls, JSON parsing, and caching in Go.

Also available in:

typescript

What will you learn?

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.

Fun building the pokedex but did not feel prepared for cache or interacting with an API, though that could be because I moved onto the SQL course can came back to this later.
