Trevi-Lime

Overview

Lime is improved web framework for Trevi, and Lime refers to express.js.

Notice

If you want to build or test all projects at Xcode, please check out Trevi-Dev. Otherwise, you can build Trevi, lime and other packages by using Swift Package manager.
Here are an example and it now runs on Linux.

Features

powerful routing
user-friendly usage
HTTP sub modules (redirection, favicon, etc)
View render supporting Swift Server Page template engines
Can parsing all type of body data
Make high performance.

Swift version

Trevi works with the latest version of Swift 3.0 or latest Snapshot. You can download Swift binaries on here.

Installation (Ubuntu; APT-based linux)

Update your local package index first.

$ sudo apt-get update && sudo apt-get upgrade

Install Swift dependencies on linux:

$ sudo apt-get install clang libicu-dev

Install Swift depending on your platform on the follow link (The latest version are recommended).
After installation of Swift, check your PATH environment variable whether Swift binary path is set or not. If it is not set execute below.:
```
$ export PATH=/path/to/swift/installed/usr/bin:"${PATH}"
```
More details : 'Linux' on here
Install git to clone libuv:
```
$ sudo apt-get install git
```

Install libuv dependencies on linux:

$ sudo apt-get install autoconf automake make build-essential libtool gcc g++

Clone libuv:

$ git clone https://github.com/libuv/libuv.git

Install libuv:

$ cd libuv
$ sh autogen.sh
$ ./configure
$ make
$ make check
$ sudo make install

More details : Build Instructions on libuv

Set LD_LIBRARY_PATH environment variable to run executable.

$ export LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:$LD_LIBRARY_PATH

Installation (OS X)

Install Swift depending on your platform on the follow link (The latest version are recommended).
After installation of Swift, check your PATH environment variable whether Swift binary path is set or not. If it is not set execute below.:
```
$ export PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:"${PATH}"
```

Clone libuv:

$ git clone https://github.com/libuv/libuv.git

Install libuv:

$ cd libuv
$ sh autogen.sh
$ ./configure
$ make
$ make check
$ sudo make install

or using Homebrew:

$ brew install --HEAD libuv

Set LD_LIBRARY_PATH environment variable to run executable.

$ export LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:$LD_LIBRARY_PATH

Usage

Create a new project directory
```
mkdir HelloLime
```
Initialize this project as a new Swift package project
```
cd HelloLime
swift build --init
```
Now your directory structure under HelloLime should look like this :
<pre> HelloLime ├── Package.swift ├── Sources │ └── main.swift └── Tests └── <i>empty</i> </pre>
Note: For more information on the Swift Package Manager, go here

Add a dependency of Trevi for your project (Package.swift) :

import PackageDescription

let package = Package(
    name: "HelloLime",
    dependencies: [
      .Package(url: "https://github.com/Trevi-Swift/Trevi-lime.git", versions: Version(0,1,0)..<Version(0,2,0)),
    ]
)

Import the modules in your code (ex: Sources/main.swift) :
```
import Trevi
import Lime
```

Implement one or more routers :

public class Root {	    
    private let lime = Lime()
    private var router: Router!
    
    public init() {        
        router = lime.router
        
        router.get("/") { req , res , next in
            res.send("Hello Lime!")
        }

        router.get("/param/:param") { req , res , next in
            if let param = req.params["param"] {
                res.send(param)
            }
            next!()
        }
    }
}

extension Root: Require {
    public func export() -> Router {
        return self.router
    }
}

Get instance of Lime and put router :

let lime = Lime()
lime.use("/", Root())
lime.use { (req, res, next) in
    res.statusCode = 404
    res.send("404 error")
}

Create and start a server :

let server = Http ()
server.createServer(lime).listen(8080)

Then your code should look like this :

import Trevi
import Lime

public class Root {	    
    private let lime = Lime()
    private var router: Router!
    
    public init() {        
        router = lime.router
        
        router.get("/") { req , res , next in
            res.send("Hello Lime!")
        }

        router.get("/param/:param") { req , res , next in
            if let param = req.params["param"] {
                res.send(param)
            }
            next!()
        }
    }
}

extension Root: Require {
    public func export() -> Router {
        return self.router
    }
}

let lime = Lime()
lime.use("/", Root())
lime.use { (req, res, next) in
    res.statusCode = 404
    res.send("404 error")
}

let server = Http()
server.createServer(lime).listen(8080)

Build your application:

Mac OS X:

swift build -Xcc -fblocks -Xswiftc -I/usr/local/include -Xlinker -L/usr/local/lib

Ubuntu:
```
swift build -Xcc -fblocks
```

Now run your application:
```
.build/debug/HelloLime
```
Open your browser at http://localhost:8080
Enjoy Lime!
