This is an overview of open source PureScript (and JavaScript) packages that facilitate Cardano dApp development.

• cardano-transaction-lib - A Purescript framework for building smart contract transactions on Cardano, known as "CTL"
• purescript-cardano-transaction-builder - Declarative transaction builder API & utility functions for automatic redeemer indexing
• purescript-cardano-types - domain types for Cardano ledger, wraps purescript-cardano-serialization-lib.
• purescript-cardano-serialization-lib - PureScript wrapper for CSL (MLabs-vendored version).
• purescript-plutus-types - Plutus-style types used for their PlutusData instances.
• purescript-cardano-plutus-data-schema - machinery for specifying PlutusDataSchema (PlutusData encoding layouts for PureScript algebraic data types) in CTL
• purescript-cardano-collateral-select - collateral selection algorithm that tries to minimize min-ADA value
• purescript-uplc-apply-args - apply PlutusData-encoded parameters to parametrized Plutus scripts
• purescript-cardano-key-wallet - an interface that exposes functionality of a private key. Used in CTL as one of the ways to sign transactions. Can be implemented via HTTP for remote signing.
• purescript-cip30-typesafe - safe error handling for CIP-30 wrappers
  • purescript-cip30 - CIP-30 API wrappers (no error handling)
• purescript-cip30-mock - a mock implementation for the Cardano Cip30 Wallet interface that can be used for testing purposes to simulate a wallet without needing to interact with an actual browser-based wallet. It is actually a valid CIP-30 implementation.
• purescript-cardano-message-signing - implementation of CIP-8/CIP-30 signData, purescript wrapper over Emurgo/message-signing
• purescript-cardano-hd-wallet - implementation of CIP-1852 using cardano-serialization-lib (private key derivation from mnemonics)
• purescript-noble-secp256k1 - cryptographic functions needed to work with Vasil hardfork features
• purescript-aeson - partial re-implementation of Argonaut with support of unquoted long integers - can be used for interoperability with Aeson, that encodes long integers unquoted. We need this for interactions with Cardano tooling in Haskell
  • json-bigint - big integer machinery (JavaScript)
• purescript-bytearrays - byte string type and utilities
• purescript-mote-testplan - effectful testplans for Mote, a testing library

• @mlabs-haskell/cardano-serialization-lib-gc - CSL version vendored by MLabs, with automatic GC added
  • @mlabs-haskell/csl-gc-wrapper - Garbage collector for CSL
• @mlabs-haskell/uplc-apply-args - JavaScript package for Plutus script parameter application

These packages haven't been fully finalized:

• purus - A fork of the PureScript compiler that compiles to Untyped Plutus Core - smart contract language of Cardano
