# KituraRedis

KituraRedis is a pure Swift client for interacting with a Redis database.

## Swift version

The latest version of Kitura-redis requires **Swift 4.0.3 or later**. You can download this version of the Swift binaries by following this [link](https://swift.org/download/). Compatibility with other Swift versions is not guaranteed.

## Usage

#### Add dependencies

Add the `Kitura-redis` package to the dependencies within your application’s `Package.swift` file. Substitute `"x.x.x"` with the latest `Kitura-redis` [release](https://github.com/Kitura/Kitura-redis/releases).

```swift

.package(url: "https://github.com/Kitura/Kitura-redis.git", from: "x.x.x")

```

Add `SwiftRedis` to your target's dependencies:

```swift

.target(name: "example", dependencies: ["SwiftRedis"]),

```

#### Import package

  ```swift

  import SwiftRedis

  ```

## Redis installation

To test Kitura-redis locally you need to install [Redis](https://redis.io).

### macOS

```

brew install redis

```

To start redis as a background service and have the service restarted at login:

```

brew services start redis

```

Or, if you don't want redis running as a background service:

```

redis-server /usr/local/etc/redis.conf

```

## Example

This example shows you how to connect and make calls to Redis from Swift.

#### Create simple Swift executable

Create a directory for this project, change into it and then initialize the project:

```

$ mkdir exampleRedis && cd exampleRedis

$ swift package init --type executable

```

Add Kitura-redis as a dependency as described above in "Add dependencies".

Now, edit your `main.swift` file to contain:

```swift

import Foundation

import SwiftRedis

let redis = Redis()

redis.connect(host: "localhost", port: 6379) { (redisError: NSError?) in

    if let error = redisError {

        print(error)

    }

    else {

        print("Connected to Redis")

        // Set a key

        redis.set("Redis", value: "on Swift") { (result: Bool, redisError: NSError?) in

            if let error = redisError {

                print(error)

            }

            // Get the same key

            redis.get("Redis") { (string: RedisString?, redisError: NSError?) in

                if let error = redisError {

                    print(error)

                }

                else if let string = string?.asString {

                    print("Redis \(string)")

                }

            }

        }

    }

}

```

Next, build the program and run it (either within Xcode or on the command line):

```

$ swift build

$ .build/debug/redisExample

```

You should see:

```

$ Connected to Redis

$ Redis on Swift

```

This shows that we've connected to Redis, set a string value for a key and then successfully retrieved the value for that key.

## Contributing

Contributions to the Kitura-redis project are welcome.  You will want to be able to test your changes locally before submitting a pull request.

The tests require a Redis server to be accessible locally on the default port (6379).  If you do not wish to install Redis permanently, you can use Docker to run a temporary instance locally as follows:

```

docker run -d -p 6379:6379 redis:alpine redis-server --requirepass password123

```

The password specified above must match the one defined in `Tests/SwiftRedis/password.txt`.  Then you can run the tests as normal, either via Xcode or with:

```

swift test

```
