PureScript is a small strongly typed programming language that compiles to JavaScript.

In this lesson, we'll see how we can get JSON decoding for free in PureScript using the Simple-JSON library. Because PureScript is a pretty powerful language, we can just declare what type we want the result to go into and get it for free!

Effortless JSON decoding with PureScript-Simple-JSON

Deserializing and serializing JSON manually is a boring, error-prone way to be able to handle JSON. This example shows how you can use Generics in Purescript to automatically derive de/serializers so that once you've written your type definition, you only need a few lines of code to handle JSON.

Automatically de/serialize JSON with Purescript-Foreign-Generics

In Purescript, we can use set data structures using Purescript-Set, but many of its functions come with an Ord typeclass constraint. In this lesson, we'll learn how to understand the typeclass constraints on a function and how to create instances of typeclasses.

Use Sets with Ord Typeclass instances

Algebraic Data Types are a fundamental part of modeling data in Purescript. In this lesson, we'll look at some common methods of defining and using them.
