Android lightweight Graphql library

An alternative network library for executing queries or mutations from a GraphQL server in a simple way. Built on top of OkHttp makes this lib is customizable and easy to use.

This lib takes care of every single use-case from GraphQL requests, and the lib is ready to go for getting the data safely. As simple as creating a Gql builder and listen to the response!

Features

• It uses OkHttp and already supported HTTP/2
• Coroutine-first, the return value is suspend function
• Supported for multiple queries or nested-query at the same request

---

Setup

Add this in your deps

implementation('app.isfaaghyth.graphql:1.0.0')

Don't forget to add the internet permission on AndroidManifest if you haven't yet

<uses-permission android:name="android.permission.INTERNET" />

How-to

Initializing the Lib in onCreate() of Application class

Gql.init("https://gql.isfa.xyz/api")

as it uses OkHttp, you can customize the OkHttpClient while initializing it like this

val okHttpClient = OkHttpClient().newBuilder()
    .addInterceptor(HttpLoggingInterceptor().apply {
        setLevel(HttpLoggingInterceptor.Level.BODY)
    })
    .build()

Gql.init("https://gql.isfa.xyz/api", okHttpClient)

Make your first simple request!

val query = """
    query user_info {
        userInfo {
            id
            name
        }
    }
""".trimIndent()

Gql.query(query)
   .get<UserInfo>(
        onSuccess = {
        },
        onError = {
        }
    )

A request with parameters

val query = """
    query user_info(${'$'}id: String, ${'$'}token: Int, ${'$'}is_active: Boolean) {
        userInfo {
            id
            name
        }
    }
""".trimIndent()

Gql.query(query)
   .parameters(mapOf(
        "id" to "user-123-xyz",
        "token" to 123456789,
        "is_active" to true
    ))
    .get<UserInfo>(
        onSuccess = {
        },
        onError = {
        }
    )

Additionals

Custom header while request

Gql.query(query)
   .headers(mapOf(
        // TODO
    ))

You can also getting the response with another data type:

// T
val response = Gql.query(query).getAsModel<T>()

// String
val response = Gql.query(query).getAsString()

// String with Callback
val response = Gql
        .query(query)
        .get(
            onSuccess = {},
            onError = {}
        )

On-Progress 👷🏽‍

• .create(GqlServices::java.class) extension for simplified (the design will similar like Retrofit)
• Supported for a raw file for gql query
