Usage

Usage is really simple mkey!

1/3) Configure

First create your client configuration:

Mailgun

let config = Mailer.Config.mailgun(key: "{mailgunApi}", domain: "{mailgunDomain}", region: "{mailgunRegion}")

SendGrid

let config = Mailer.Config.sendGrid(key: "{sendGridApiKey}")

SMTP

Use the SMTP struct as a handle to your SMTP server:

let smtp = SMTP(hostname: "smtp.gmail.com",     // SMTP server address
                   email: "[email protected]",     // username to login
                password: "password")           // password to login
                
let config = Mailer.Config.smtp(smtp)

SMTP using TLS

All parameters of SMTP struct:

let smtp = SMTP(hostname: String,
                   email: String,
                password: String,
                    port: Int32 = 465,
                  useTLS: Bool = true,
        tlsConfiguration: TLSConfiguration? = nil,
             authMethods: [AuthMethod] = [],
             accessToken: String? = nil,
              domainName: String = "localhost",
                 timeout: UInt = 10)
                 
let config = Mailer.Config.smtp(smtp)

2/3) Register service

Register and configure the service in your apps configure method.

Mailer(config: config, registerOn: &services)

Mailer.Config is an enum and you can choose from any integrated services to be used

3/3) Send an email

let mail = Mailer.Message(from: "[email protected]", to: "[email protected]", subject: "Oil spill", text: "Oooops I did it again", html: "<p>Oooops I did it again</p>")
return try req.mail.send(mail).flatMap(to: Response.self) { mailResult in
    print(mailResult)
    // ... Return your response for example
}

Testing

Mailcore provides a MailCoreTestTools framework which you can import into your tests to get MailerMock.

To register, and potentially override any existing "real" Mailer service, just initialize MailerMock with your services.

// Register
MailerMock(services: &services)

// Retrieve in your tests
let mailer = try! req.make(MailerService.self) as! MailerMock

MailerMock will store the last used result as well as the received message and request. Structure of the moct can be seen below:

public class MailerMock: MailerService {

    public var result: Mailer.Result = .success
    public var receivedMessage: Mailer.Message?
    public var receivedRequest: Request?

    // MARK: Initialization

    @discardableResult public init(services: inout Services) {
        services.remove(type: Mailer.self)
        services.register(self, as: MailerService.self)
    }

    // MARK: Public interface

    public func send(_ message: Mailer.Message, on req: Request) throws -> Future<Mailer.Result> {
        receivedMessage = message
        receivedRequest = req
        return req.eventLoop.newSucceededFuture(result: result)
    }

    public func clear() {
        result = .success
        receivedMessage = nil
        receivedRequest = nil
    }

}
