QAIL SDKs

Dedicated SDK Page: TypeScript, Swift, Kotlin

Canonical page for qail sdk, qail typescript sdk, qail swift sdk, and qail kotlin sdk intent. Driver intent stays on dedicated driver pages.

SDK Hub @qail/client v0.1.0 Swift Package Kotlin JVM Updated March 24, 2026

SDK Capability Matrix

Matrix below is sourced directly from qail.rs/sdk project files: TypeScript package metadata and client source, Swift package config/client source, and Kotlin Gradle/client source.

SDK Package Version Runtime Source Notes
TypeScript @qail/client 0.1.0 Node.js >= 18 sdk/typescript Builder API, raw DSL query/batch, schema type generation, and WebSocket subscription support.
Swift Qail (Swift package) swift-tools-version 6.0 iOS 15+, macOS 12+, tvOS 15+, watchOS 8+ sdk/swift Async/await SDK with fluent builders, aggregate helpers, openapi/schema utilities, and WebSocket subscription support.
Kotlin io.qail (Gradle module) 0.1.0 Kotlin JVM 2.3.0 + Ktor 3.0.3 sdk/kotlin Fluent builders, aggregate and upsert helpers, raw DSL query/batch, schema/openapi helpers, and WebSocket subscription support.

Intent Split to Prevent Cannibalization

SDK intent is centralized on /sdk, while protocol-driver intent stays on /rust and /zig pages.

Feature Parity Snapshot

TypeScript

@qail/client exposes builder APIs (from/into/update/delete), raw DSL (query, batch), utility endpoints (health/openapi/schema/generateTypes), and WebSocket subscriptions.

Swift

Swift package client provides async/await query builders, aggregate and upsert helpers, raw DSL and batch paths, utility endpoints, plus WebSocket subscribe/unsubscribe flow.

Kotlin

Kotlin JVM SDK (Ktor-based) mirrors builder/query semantics with typed responses, aggregate/upsert helpers, openapi/schema utilities, and WebSocket subscription support.

Getting Started

1. TypeScript Package

Install the published TypeScript SDK package.

npm install @qail/client

2. Swift SDK Source Module

Swift SDK currently lives in the monorepo source path.

git clone https://github.com/qail-io/qail.git
cd qail/sdk/swift
swift test

3. Kotlin SDK Source Module

Kotlin SDK is provided as a Gradle JVM module in the monorepo.

git clone https://github.com/qail-io/qail.git
cd qail/sdk/kotlin
./gradlew test

FAQ

Which SDK is published in a package registry right now?

TypeScript is available as @qail/client version 0.1.0. Swift and Kotlin are consumed from sdk/swift and sdk/kotlin in the monorepo.

Do Swift and Kotlin have the same query model as TypeScript?

Mostly yes. All three tracks expose builder-style queries, raw DSL/batch paths, aggregate helpers, and schema/openapi utility surfaces.

How does realtime work in the SDK layer?

Each SDK includes WebSocket subscription primitives so clients can subscribe/unsubscribe to gateway realtime streams without hand-writing protocol frames.

When should I choose SDKs versus the native drivers?

Choose /sdk for app integration. Choose /rust or /zig when you need transport-level PostgreSQL behavior, pooling internals, and protocol control.
