SwiftNIO Redis Client

Swift5 macOS tuxOS Travis

SwiftNIO Redis is a Swift package that contains a high performance Redis protocol implementation for SwiftNIO. This is a standalone project and has no other dependencies but SwiftNIO.

Apart from the protocol implementation which can encode and decode RESP (REdis Serialization Protocol), we also provide a Redis client module build on top.

What is Redis? Redis is a highly scalable in-memory data structure store, used as a database, cache and message broker. For example it can be used to implement a session store backing a web backend using its "expiring keys" feature, or it can be used as a relay to implement a chat server using its builtin PubSub features.

This Swift package contains a simple Redis client based on the protocol implementation swift-nio-redis. We also provide an actual Redis Server written in Swift, using SwiftNIO and SwiftNIO Redis.

Importing the module using Swift Package Manager

An example Package.swift importing the necessary modules:

// swift-tools-version:5.0

import PackageDescription

let package = Package(
    name: "RedisTests",
    dependencies: [
        .package(url: "https://github.com/NozeIO/swift-nio-redis-client.git", 
                 from: "0.10.0")
    ],
    targets: [
        .target(name: "MyClientTool",
                dependencies: [ "Redis" ])
    ]
)

Using the Redis client module

The Redis client module is modeled after the Node.js node_redis module, but it also supports NIO like Promise/Future based methods in addition to the Node.js (err,result) style callbacks. Choose your poison.

Simple KVS use example:

import Redis

let client = Redis.createClient()

client.set ("counter", 0, expire: 2)
client.incr("counter", by: 10)
client.get ("counter") { err, value in
    print("Reply:", value)
}
client.keys("*") { err, reply in
    guard let keys = reply else { return print("got no keys!") }
    print("all keys in store:", keys.joined(separator: ","))
}

Using NIO Promises:

client
    .set ("counter", 0, expire: 2)
    .then {
        client.incr("counter", by: 10)
    }
    .then {
        client.get("counter")
    }
    .map {
        print("counter is:", $0)
    }

Status

The protocol implementation is considered complete. There are a few open ends in the telnet variant, yet the regular binary protocol is considered done.

The Redis client module has a few more open ends, but seems to work fine.
