graphql-client

Hiccup-like syntax for GraphQL in Clojure(Script).

Usage

Takes a GraphQL query in Hiccup syntax like this.

(def plan-query [[:plan {:fromPlace "Kamppi, Helsinki"
                         :from {:lat 60.168992 :lon 24.92366}
                         :toPlace "Pisa, Espoo"
                         :to {:lat 60.175294 :lon 24.684855}
                         :numItineraries 5
                         :modes "BICYCLE_RENT,BUS,WALK"
                         :walkReluctance 2.1
                         :walkBoardCost 600
                         :minTransferTime 180
                         :walkSpeed 1.2
                         :maxWalkDistance 10000}
                  [:itineraries
                   :walkDistance
                   :duration
                   [:legs :mode :startTime :endTime
                    [:from :lat :lon :name [:stop :code :name]]
                    [:to :lat :lon :name]
                    [:agency :id]
                    :distance
                    [:legGeometry :length :points]]]]])

And produces a GraphQL query string like this (without any pretty printing).

{plan(fromPlace:"Kamppi, Helsinki",from:{lat:60.168992,lon:24.92366},toPlace:"Pisa, Espoo",to:{lat:60.175294,lon:24.684855},numItineraries:5,modes:"BICYCLE_RENT,BUS,WALK",walkReluctance:2.1,walkBoardCost:600,minTransferTime:180,walkSpeed:1.2,maxWalkDistance:10000){itineraries{walkDistance,duration,legs{mode startTime endTime from{lat lon name stop{code name}},to{lat lon name},agency{id},distance legGeometry{length points}}}}}

You can execute this query in the Digitransit GraphiQL console.

TODO

• Creating queries based on the query string
• Creating introspection queries
• Metadata validation generation using e.g. Schema
• Useful transformations of the results
• Comprehensive support for all kinds of things
• CLJC
