# purescript-graphql-fundeps

Type-safe graphql queries using functional dependencies.

Use the `GraphQLReqRes` class to define expected input and output.

Then, create a `client` and use it to interact with your API.

```purescript

endpoint = "https://api.react-finland.fi/graphql" :: String

foreign import data ReactFinlandConferences :: GraphQL

instance graphqlReactFinlandConferences ::

  GraphQLReqRes ReactFinlandConferences """query {

  conferences {

    name

    id

  }

}

""" () ( conferences :: Array { name :: String, id :: String } )

foreign import data ReactFinlandConference :: GraphQL

instance graphqlReactFinlandConference ::

  GraphQLReqRes ReactFinlandConference """query($id:ID!) {

  conference(id:$id) {

    year

    websiteUrl

    speakers {

      firstName

      lastName

    }

  }

}

""" ( id :: String ) ( conference ::

        { year :: String

        , websiteUrl :: String

        , speakers ::

            Array

              { firstName :: String

              , lastName :: String

              }

        }

    )

client :: GraphQLClientAff

client = graphQL "https://api.react-finland.fi/graphql" [] driver

main ∷ Effect Unit

main =

  launchAff_  do

    { conferences } <- client (Gql :: Gql ReactFinlandConferences) {}

    for_ conferences \{ id } -> do

      { conference: { websiteUrl, speakers } } <- client (Gql :: Gql ReactFinlandConference) { id }

      Log.info websiteUrl

      Log.info $ show speakers

```

You can check out the [test](./test/Main.purs) for a full example.

## Development

You can either use the nix shell, or the npm package.

### Nix shell

Buliding:

```

spago build

```

Testing:

```

spago -x test.dhall test

```

### Npm

Just run `npm i` and then:

Building:

```
