## About

The repository provides an API definition, data types, client and utilities

for working with Blockfrost. We are striving to provide beginner-friendly

interface while adding a bit of type safety, especially when working with monetary

values.

### Packages

* [`blockfrost-api`](./blockfrost-api/#readme)

  Types, sample data, API definition and tests. See the [`README.md`](./blockfrost-api/#readme)

  for quick tutorial

* [`blockfrost-client-core`](./blockfrost-client-core/#readme)

  Instances and helpers shared by all clients.

* [`blockfrost-client`](./blockfrost-client/#readme)

  Blockfrost client for use with `mtl`. Its [`README.md`](./blockfrost-api/#readme)

  contains an introduction and usage examples.

* [`blockfrost-pretty`](./blockfrost-pretty/#readme)

  Pretty printing utilities for pretty printing Ada values

  and various Blockfrost types.

## Getting started

To use this SDK, you first need to log in to [blockfrost.io](https://blockfrost.io), create your project and retrieve the API token.






## Installation

Packages are available on Hackage, you only need to add `blockfrost-client`

to your package dependencies.

Haddocks available on Hackage:

* [![Hackage blockfrost-api](https://img.shields.io/hackage/v/blockfrost-api.svg?logo=haskell&style=flat-square&label=blockfrost-api)](https://hackage.haskell.org/package/blockfrost-api)

* [![Hackage blockfrost-client](https://img.shields.io/hackage/v/blockfrost-client.svg?logo=haskell&style=flat-square&label=blockfrost-client)](https://hackage.haskell.org/package/blockfrost-client)

* [![Hackage blockfrost-pretty](https://img.shields.io/hackage/v/blockfrost-pretty.svg?logo=haskell&style=flat-square&label=blockfrost-pretty)](https://hackage.haskell.org/package/blockfrost-pretty)

## 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:

```bash

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`:

```bash

git clone https://github.com/blockfrost/blockfrost-haskell

cd blockfrost-haskell

nix-shell

cabal build all

cabal repl blockfrost-client

```

## Usage

See [blockfrost-client](./blockfrost-client/#readme) for a tutorial

and usage examples.

Readme of [blockfrost-api](./blockfrost-api/#readme)

contains a short primer for working with Blockfrost

types, data samples and monetary values.
