Introduction

RediStack (pronounced like "ready stack") is a non-blocking Swift client for Redis built on top of SwiftNIO.

It communicates over the network using Redis' Redis Seralization Protocol (RESP2).

The table below lists the major releases alongside their compatible language, dependency, and Redis versions.

SPM Version	Swift	Redis	SwiftNIO	SwiftLog	SwiftMetrics
from: "1.0.0-alpha.5"	5.0+	5.0+	2.x	1.x	1.x

Supported Operating Systems

RediStack runs anywhere that is officially supported by the Swift project.

See the test matrix below for more details.

Installing

To install RediStack, just add the package as a dependency in your Package.swift.

dependencies: [
    .package(url: "https://gitlab.com/mordil/swift-redi-stack.git", from: "1.0.0-alpha.5")
]

Getting Started

RediStack is quick to use - all you need is an EventLoop from SwiftNIO.

import NIO
import RediStack

let eventLoop: EventLoop = ...
let connection = RedisConnection.connect(
    to: try .init(ipAddress: "127.0.0.1", port: RedisConnection.defaultPort),
    on: eventLoop
).wait()

let result = try connection.set("my_key", to: "some value")
    .flatMap { return connection.get("my_key") }
    .wait()

print(result) // Optional("some value")

Note: Use of wait() was used here for simplicity. Never call this method on an eventLoop!
