Development setup

You can either work within this repository using plain cabal or in combination with nix.

cabal

If you already have GHC and cabal installed:

git clone https://github.com/blockfrost/blockfrost-haskell
cd blockfrost-haskell
cabal update
cabal build all
cabal repl blockfrost-client

Note: Due to TLS support, you might need to provide zlib headers if compilation of http-client-tls fails. (On NixOS this is nix-shell -p zlib.dev).

nix

Using nix-shell, you can obtain a preconfigured environment with GHC and cabal:

git clone https://github.com/blockfrost/blockfrost-haskell
cd blockfrost-haskell
nix-shell
cabal build all
cabal repl blockfrost-client

Usage

See blockfrost-client for a tutorial and usage examples.

Readme of blockfrost-api contains a short primer for working with Blockfrost types, data samples and monetary values.
