安裝

Add InsForge dependencies to your project

Maven Central
GitHub Packages

build.gradle.kts:

repositories {
    mavenLocal() // For local development
    mavenCentral()
}

dependencies {
    implementation("dev.insforge:insforge-kotlin:0.1.6")
}

First, create a GitHub Personal Access Token:

Go to GitHub → Settings → Developer settings → Personal access tokens → Tokens (classic)
Select permission: read:packages

Then configure your project using one of the following methods:

Option A: Environment Variables

settings.gradle.kts (or build.gradle.kts):

repositories {
    mavenCentral()
    maven {
        url = uri("https://maven.pkg.github.com/InsForge/insforge-kotlin")
        credentials {
            username = System.getenv("GITHUB_USER") ?: ""
            password = System.getenv("GITHUB_TOKEN") ?: ""
        }
    }
}

build.gradle.kts:

dependencies {
    implementation("dev.insforge:insforge-kotlin:0.1.6")
}

Set environment variables before building:

export GITHUB_USER="your-github-username"
export GITHUB_TOKEN="your-personal-access-token"

Option B: gradle.properties (Local Development)

Add credentials to your global Gradle properties file:~/.gradle/gradle.properties:

gpr.user=your-github-username
gpr.token=ghp_xxxxxxxxxxxx

settings.gradle.kts:

repositories {
    mavenCentral()
    maven {
        url = uri("https://maven.pkg.github.com/InsForge/insforge-kotlin")
        credentials {
            username = providers.gradleProperty("gpr.user").orNull ?: ""
            password = providers.gradleProperty("gpr.token").orNull ?: ""
        }
    }
}

build.gradle.kts:

dependencies {
    implementation("dev.insforge:insforge-kotlin:0.1.6")
}

The ~/.gradle/gradle.properties file is stored outside your project, so credentials won’t be accidentally committed to version control.

Initialize InsForge SDK

import dev.insforge.createInsforgeClient
import dev.insforge.auth.Auth
import dev.insforge.database.Database
import dev.insforge.storage.Storage
import dev.insforge.functions.Functions
import dev.insforge.realtime.Realtime
import dev.insforge.ai.AI

val client = createInsforgeClient(
    baseUrl = "https://your-app.insforge.app",
    anonKey = "your-api-key"
) {
    install(Auth)
    install(Database)
    install(Storage)
    install(Functions)
    install(Realtime) {
        autoReconnect = true
        reconnectDelay = 5000
    }
    install(AI)
}

Enable Logging (Optional)

For debugging, you can configure the SDK log level:

import dev.insforge.InsforgeLogLevel

val client = createInsforgeClient(
    baseUrl = "https://your-app.insforge.app",
    anonKey = "your-api-key"
) {
    // DEBUG: logs request method/URL and response status
    // VERBOSE: logs full headers and request/response bodies
    logLevel = InsforgeLogLevel.DEBUG

    install(Auth)
    install(Database)
    // ... other modules
}

Log Level	Description
`NONE`	No logging (default, recommended for production)
`ERROR`	Only errors
`WARN`	Warnings and errors
`INFO`	Informational messages
`DEBUG`	Debug info (request method, URL, response status)
`VERBOSE`	Full details (headers, request/response bodies)

Use NONE or ERROR in production to avoid exposing sensitive data in logs.

Android Initialization

Add Chrome Custom Tabs dependency to your build.gradle.kts:

dependencies {
    implementation("androidx.browser:browser:1.9.0")
}

Initialize InsForge SDK (With Chrome Custom Tabs and Session Storage)

import android.app.Activity
import android.content.Context
import android.content.Intent
import android.net.Uri
import androidx.browser.customtabs.CustomTabsIntent
import dev.insforge.createInsforgeClient
import dev.insforge.ai.AI
import dev.insforge.auth.Auth
import dev.insforge.auth.BrowserLauncher
import dev.insforge.auth.ClientType
import dev.insforge.auth.SessionStorage
import dev.insforge.database.Database
import dev.insforge.functions.Functions
import dev.insforge.realtime.Realtime
import dev.insforge.storage.Storage

class InsforgeManager(private val context: Context) {

    val client = createInsforgeClient(
        baseUrl = "https://your-app.insforge.app",
        anonKey = "your-anon-key"
    ) {
        install(Auth) {
            // 1. Chrome Custom Tabs - opens in-app, similar to iOS ASWebAuthenticationSession
            browserLauncher = BrowserLauncher { url ->
                val customTabsIntent = CustomTabsIntent.Builder()
                    .setShowTitle(true)
                    .build()
                // Handle non-Activity context safely
                if (context is Activity) {
                    customTabsIntent.launchUrl(context, Uri.parse(url))
                } else {
                    customTabsIntent.intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
                    customTabsIntent.launchUrl(context, Uri.parse(url))
                }
            }

            // 2. enable session persistence
            persistSession = true

            // 3. config SessionStorage (use SharedPreferences)
            sessionStorage = object : SessionStorage {
                private val prefs = context.getSharedPreferences(
                    "insforge_auth",
                    Context.MODE_PRIVATE
                )

                override suspend fun save(key: String, value: String) {
                    prefs.edit().putString(key, value).apply()
                }

                override suspend fun get(key: String): String? {
                    return prefs.getString(key, null)
                }

                override suspend fun remove(key: String) {
                    prefs.edit().remove(key).apply()
                }
            }

            // 4. set client type for mobile
            clientType = ClientType.MOBILE
        }
        // Install Database module
        install(Database)

        // Install Realtime module for real-time subscriptions
        install(Realtime) {
            debug = true
        }
        // Install other modules
        install(Storage)
        install(Functions)
        install(AI)
    }
}

Use Jetpack DataStore for Session Storage (Optional)

import androidx.datastore.core.DataStore
import androidx.datastore.preferences.core.Preferences
import androidx.datastore.preferences.core.edit
import androidx.datastore.preferences.core.stringPreferencesKey
import androidx.datastore.preferences.preferencesDataStore
import kotlinx.coroutines.flow.first
import kotlinx.coroutines.flow.map

val Context.authDataStore: DataStore<Preferences> by preferencesDataStore(name = "insforge_auth")

class DataStoreSessionStorage(private val context: Context) : SessionStorage {
    
    override suspend fun save(key: String, value: String) {
        context.authDataStore.edit { prefs ->
            prefs[stringPreferencesKey(key)] = value
        }
    }
    
    override suspend fun get(key: String): String? {
        return context.authDataStore.data.map { prefs ->
            prefs[stringPreferencesKey(key)]
        }.first()
    }
    
    override suspend fun remove(key: String) {
        context.authDataStore.edit { prefs ->
            prefs.remove(stringPreferencesKey(key))
        }
    }
}

// Then use it in your InsForge client
install(Auth) {
    browserLauncher = ...
    persistSession = true
    sessionStorage = DataStoreSessionStorage(context)
}
