Argonaut

Argonaut is a collection of libraries for working with JSON in PureScript. This library bundles together the following:

• purescript-argonaut-core provides basic parsing, printing, folding and types for Json.
• purescript-argonaut-codecs provides codecs based on EncodeJson and DecodeJson type classes (along with instances for common data types) and combinators for encoding and decoding Json values.
• purescript-argonaut-traversals defines prisms, traversals, zippers, and JCursor for the Json type.

Installation

Install argonaut with Spago:

spago install argonaut

You can also install Argonaut libraries individually (for example, by only installing argonaut-core for the Json type).

Quick start

This library bundles together several other libraries. We recommend checking out the quick starts for those libraries depending on which use case you're looking for:

• To learn more about the basic data types and parsing functions in Argonaut, see purescript-argonaut-core.
• To learn more about encoding and decoding PureScript types to and from Json using type classes, see purescript-argonaut-codecs.
• To learn more about encoding and decoding PureScript types to and from Json using profunctors, see purescript-codec-argonaut.
• To learn more about manipulating Json using optics and JCursor, see purescript-argonaut-traversals

Documentation

argonaut documentation is stored in a few places:

1. Module documentation is published on Pursuit.
2. Written documentation is kept in the docs directory.
3. Usage examples can be found in the test suite.

If you get stuck, there are several ways to get help:

• Open an issue if you have encountered a bug or problem.
• Ask general questions on the PureScript Discourse forum or the PureScript Discord chat.
