+# NIORedis
 
-> **NOTE: This this is written against SwiftNIO 2.0, and as such requires Swift 5.0!**
+* Pitch discussion: [Swift Server Forums](https://forums.swift.org/t/swiftnio-redis-client/19325)
+* Proposal: [SSWG-0004](https://github.com/swift-server/sswg/blob/56a26b50ade45d624b54abe13c7d1f88526f9bb1/proposals/0004-nio-redis.md)
 
-This is to take advantage of the [`Result`](https://github.com/apple/swift-evolution/blob/master/proposals/0235-add-result.md) type in the `DispatchRedis` module,
-and to stay ahead of development of the next version of SwiftNIO.
+## Installation
+
+To install `NIORedis`, just add the package as a dependency in your [**Package.swift**](https://github.com/apple/swift-package-manager/blob/master/Documentation/PackageDescriptionV4.md#dependencies)
 
 ```swift
-import NIORedis
+dependencies: [
+    .package(url: "https://github.com/Mordil/nio-redis.git", .upToNextMinor(from: "0.2.0")
+]
+```
 
-let elg = MultiThreadedEventLoopGroup(numberOfThreads: 1)
-let driver = RedisDriver(ownershipModel: .external(elg))
+and run the following command: `swift package resolve`
 
-// connections
+## Getting Started
 
-// passing a value to 'password' will automatically authenticate with Redis before resolving the connection
-let connection = try redis.makeConnection(
-    hostname: "localhost", // this is the default
-    port: 6379, // this is the default
-    password: "MY_PASS" // default is 'nil'
-).wait()
+`NIORedis` is ready to use right after installation.
 
-// convenience methods for commands
+```swift
+import NIORedis
 
-let result = try conneciton.set("my_key", to: "some value")
-    .then { return connection.get("my_key")}
-    .wait()
-print(result) // Optional("some value")
+let driver = NIORedisDriver(ownershipModel: .internal(threadCount: 2))
 
-// raw commands
+let connection = try driver.makeConnection().wait()
 
-let keyCount = try connection.command("DEL", [RESPValue(bulk: "my_key")])
-    .thenThrowing { response in
-        guard case let .integer(count) else {
-            // throw error
-        }
-        return count
-    }
+let result = try connection.set("my_key", to: "some value")
+    .flatMap { return connection.get("my_key" }
     .wait()
-print(keyCount) // 1
-
-// cleanup
 
-connection.close()
-    .thenThrowing { try redis.terminate() }
-    .whenSuccess { try elg.syncShutdownGracefully() }
+print(result) // Optional("some value")
 ```

-### RESPValue & RESPValueConvertible
-This is a 1:1 mapping enum of the `RESP` types: `Simple String`, `Bulk String`, `Array`, `Integer` and `Error`.
-
-Conforming to `RESPValueConvertible` allows Swift types to more easily convert between `RESPValue` and native types.
-
-`Array`, `Data`, `Float`, `Double`, `FixedWidthInteger`, `String`, and of course `RESPValue` all conform in this package.
