local request  = require("request")

Mail = require("core").Object:extend()

function Mail:initialize(option)
    if not(option) then return false end
    self.api  = option.api
    self.domain = option.domain
    self.defaultFrom = option.from
end

function Mail:send (opt, callback)
    request.post("https://api.mailgun.net/v3/"..self.domain.."/messages")
    :set("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8")
    :send({
        from = opt.from or self.defaultFrom,
        to   = opt.to,
        subject = opt.subject,
        text = opt.text,
        html = opt.html
    })
    :auth("api", self.api)
    :done(callback)
end

module.exports = Mail

Then you can send email via:

local mail = require("./mailgun"):new({
    api = "key-xxxx-xxxxx-xxxxxxxxxxxxx",
    domain = "example.com"
})

mail:send({
    from = "[email protected]",
    to = "[email protected]",
    subject = "Hello from Luvit Request",
    html = "<h1>Hello World!</h1>",
    text = "Hello World!"
}, function(err, res)
    p(err, res.body)
end)
