SwiftyBeaver Logging Provider for Vapor

Adds the powerful logging of SwiftyBeaver to Vapor for server-side Swift 4 on Linux and Mac.

Installation

Add this project to the Package.swift dependencies of your Vapor project:

  .package(url: "https://github.com/vapor-community/swiftybeaver-provider.git", from: "3.0.0")

Setup

After you’ve added the SwiftyBeaver Provider package to your project, setting the provider up in code is easy.

You can configure your SwiftyBeaver instance in a pure swift way or using a JSON file like Vapor 2 do,

Register using a pure swift way

import SwiftBeaverProvider

public func configure(_ config: inout Config, _ env: inout Environment, _ services: inout Services ) throws {
    // ...

    // Setup your destinations
    let console = ConsoleDestination()
    console.minLevel = .info // update properties according to your needs

    let fileDestination = FileDestination()

    // Register the logger
    services.register(SwiftyBeaverLogger(destinations: [console, fileDestination]), as: Logger.self)

    // Optional
    config.prefer(SwiftyBeaverLogger.self, for: Logger.self)
}

Register using a JSON file

First, register the SwiftyBeaverProvider in your configure.swift file.

import SwiftBeaverProvider

public func configure(_ config: inout Config, _ env: inout Environment, _ services: inout Services ) throws {
    // ...

    // Register providers first
    try services.register(SwiftyBeaverProvider())

    // Optional
    config.prefer(SwiftyBeaverLogger.self, for: Logger.self)
}

Configure Destinations

If you run your application now, you will likely see an error that the SwiftyBeaver configuration file is missing. Let’s add that now

The configuration consist of an array of destinations located in Config/swiftybeaver.json file. Here is an example of a simple SwiftyBeaver configuration file to configure console, file and swiftybeaver platform destinations with their required properties.

[
  {
    "type": "console",
    "format": " $Dyyyy-MM-dd HH:mm:ss.SSS$d $C$L$c: $M"
  },
  {
    "type": "file"
  },
  {
    "type": "platform",
    "app": "YOUR_APP_ID",
    "secret": "YOUR_SECRET_ID",
    "key": "YOUR_ENCRYPTION_KEY"
  }
]

Aditional options:

KEY	AVAILABLE FOR	TYPE	OBSERVATION
async	console, file	Bool
format	console, file	String	A space must be placed before dollar sign
levelString.debug	console, file	String
levelString.error	console, file	String
levelString.info	console, file	String
levelString.verbose	console, file	String
levelString.warning	console, file	String
path	file	String	path to the log file
minLevel	console, file, platform	String	values: verbose, debug, info, warning, error
threshold	platform	Int	min: 1, max: 1000

Note:
It’s a good idea to store the SwiftyBeaver configuration file in the Config/secrets folder since it contains sensitive information.

To get more information about configuration options check the official SwiftyBeaver docs

Use

router.get("hello") { req -> Future<String> in
    // Get a logger instance
    let logger: Logger = try req.make(SwiftyBeaverLogger.self)

    // Or
    let logger: Logger = try req.make(Logger.self) // needs config.prefer(SwiftyBeaverLogger.self, for: Logger.self) in configure.swift

    logger.info("Logger info")
    return Future("Hello, world!")
}
