purescript-bridge

Translate your Haskell types to PureScript types. It should in theory work for almost all Haskell types, including type constructors! You just have to instantiate it with dummy parameters from e.g. “Language.PureScript.Bridge.TypeParameters”.

Data type translation is fully and easily customizable by providing your own BridgePart instances!

The latest version of this project requires Purescript 0.15.

JSON encoding / decoding

For compatible JSON representations:

On Haskell side:
- Use aeson’s generic encoding/decoding with default options
On Purescript side:
- Use purescript-argonaut-aeson-generic >=0.4.1 (GitHub)
- Or use purescript-foreign-generic.
  - This branch is updated for Purescript 0.15.

Documentation

Usage of this library is documented in Language.Purescript.Bridge, with writePSTypes you should have everything to get started. Documentation can be found here.

Status

It works for my use case and is used in production. PRs for more PSTypes definitions and bridges are very welcome!
