• Pursuit - The website containing documentation for PureScript packages.
• esbuild - JavaScript bundler used by Spago.
• purs-tidy - Purescript code formatter.
• purescript-backend-optimizer - A tool to optimize JS genererated code.

Essential libraries

• prelude - The basic prelude.
• effect - Native side effects (equivalent to IO in Haskell).
• aff - Asynchronous effects.
• maybe - Optional values.
• either - Commonly used for error handling.
• arrays - JavaScript arrays.
• transformers - Monad transnformers ReaderT, StateT, MaybeT, etc (equivalent to mtl in Haskell).

Documentation, references and tutorials

• PureScript: Jordan's Reference - A comprehensive reference for the PureScript language and its idioms, ranging from total beginner to advanced topics.
• PureScript by Example - A short but dense book from the creator of PureScript (with excercises).

Data types

• ordered-collections - Ordered Maps and Sets.
• unordered-collections - Hash-based immutable Maps and Sets.
• lists - Linked lists.
• fast-vect - Fast, type-safe vector libary for Purescript inspired by Idris. A vector is list with its size encoded in the type.
• tree-rose - Tree zippers.
• 📀 record-studio - Working with records made easy.
• 🎄 yoga-tree - A data type for representing trees with arbitrary number of children and handy zippers.
• 🕉️ yoga-om - A powerful general purpose type for writing applications. Includes dependency injection via Reader, error Variants and of course Aff.
• 💍 untagged-union - A data type for untagged unions.
• 🔑 vault - A typed, persistent store for values of arbitrary types. This is a port of the Haskell Vault library by Heinrich Apfelmus.
• ❄️ unique - Abstract unique objects.

Maths

• js-bigints - FFI bindings for JavaScript's BigInt. Does not require external js libraries.
• rationals - Rational numbers.

Random

• random - A basic library to generate random numbers.
• gen - A type class for random generator implementations.
• generate-values - An instance for gen and additional functions.

Lenses

• profunctor-lenses - A mechanism for updating, viewing, and setting values within nested data structures.
• barlow-lens - Barlow lens makes creating complex lenses such as record lenses super simple.
• tidy-codegen-lens - Generate lenses and prisms for your data types automatically.

Http

Http client

• fetch - High-level library for the WHATWG Fetch Living Standard.

Http server

• httpurple - A functional http server with a focus on type-safety and making the common case easy.

Http routing

• routing-duplex - Simple bidirectional parser/printers for your routing data types.

GraphQL

• graphql-fundeps - GraphQL client.

Json

• yoga-json - Light-weight Json parser.
• argonaut - A collection of libraries for working with JSON in PureScript.

• quickcheck - An implementation of QuickCheck in PureScript.
• assert - Basic assertions library for low level testing.

Benchmark

• minibench - A minimal benchmarking library.

FFI

• 🦥 lazy-joe - Purescript ffi for the lazy joe.
• js-objects - Access js object methods and properties without writing JS bindings.

IDEs

• VS Code - VS Code extension.
• IntelliJ - IntelliJ extension.

Organisations

The following organisations are the best entry points when looking for libraries (many of the libraries in this list come from these orgs):

• purescript - Core libraries for purescript.
• purescript-contrib - Common libraries that complement the core libraries.
• purescript-web - Low-level bindings to common web specifications (standards).
• purescript-node - Common libraries that complement the core libraries.
• rowtype-yoga - High quality, type-safe libraries from us 😎.
• purescript-react - Libraries to work with the react ecosystem.
