V1

Mailon is a templating engine for tempate emails.

Getting Started

1. Create Templates

Create a template folder anywhere in your project folder. All template files should end in .html. We should stick to the following naming convention filename.langcode.html. The langcode will be used to retrieve the correct translation of the email if your app supports it.

Example Filenames

const exampleFileNameEnglish = 'welcome.en.html'
const exampleFileNameChinese = 'welcome.zh.html'

Example Welcome Email in English: welcome.en.html

<h1>Welcome to company.name</h1>
<p>you have created a new account, below are your account credentials:</p>
<ul>
    <li>username: ${user.username}</li>
    <li>password: ${user.password}</li>
</ul>

For more information please click <a href="${link}">here</a>

Example Welcome Email in Chinese: welcome.en.html

<h1>账户主次成功</h1>
<p>下边是您账户信息:</p>
<ul>
    <li>用户名: ${user.username}</li>
    <li>密码: ${user.password}</li>
</ul>

2. Setting up Mailon

const { mailon } = require('./mailmap')
const instance = mailon('path-where-you-store-your-templates')
instance.langTo('zh')

3. Getting and rendering emails with Mailon

instance.get('welcome', data)

output

<h1>账户主次成功</h1>
<p>下边是您账户信息:</p>
<ul>
    <li>用户名: some-username</li>
    <li>密码: some-password</li>
</ul>

更多信息， 请按<a href="some-link">here</a>

4. Express Middleware Example

Note: if you wish to set the langue you will have set a lang property on your request object before instantiating notis.

const mailon = require('./mailmap')('path-where-you-store-your-templates')

// mount to express app
app.use(mailon())


// accessing in express route

const SomeExpressRoute = async (req, res, next) => {

    const data = {
        user: { ... },
        invoice: { ... }
    }

    const email = req.mailon.get('some-email-template', data)

    next()

}
