How to generate Html file with Mjml framework in ASP.NET Core MVC?

Question

I am sending an e-mail using mailkit and mimekit like this:

MimeMessage message = new MimeMessage();
message.From.Add(new MailboxAddress("najmahan", "[email protected]"));
message.To.Add(MailboxAddress.Parse("najmahan.com"));
message.Subject = "Transactions between " + startDate + "and " + endDate;

var bodyBuilder = new BodyBuilder();
bodyBuilder.HtmlBody = $"<table><tr><th>Account</th><th>Amount</th><th>Date</th><th>Type</th></tr>";

foreach (var item in model.AllTransactions)
{
    /*Console.WriteLine(item.Account_Name + "-" + item.Amount + "-" + item.Date);*/
    bodyBuilder.HtmlBody += $"<tr><td>{item.Account_Name}</td><td>{item.Amount}</td><td>{item.Date}</td><td>{item.Type}</td></tr>";
}

foreach (var item in model.IncomeLists)
{
    bodyBuilder.HtmlBody += $"<b>Total Income: {item.Income}</b><br>";
}

foreach (var item in model.ExpenseLists)
{
    bodyBuilder.HtmlBody += $"<b>Total Expense: {item.Expense}</b><br>";
}

bodyBuilder.TextBody = "This is some plain text";

var prehtml = "<mjml><mj-body><mj-container><mj-section><mj-column><mj-text>Hello World!</mj-text></mj-column></mj-section></mj-container></mj-body></mjml>";

message.Body = bodyBuilder.ToMessageBody();

In this by using bodyBuilder.HtmlBody. I wanted to use MJML(responsive email framework) which should generate HTML text and append with message.

How can I do this. if there is just a default mjml code generated and append with message will also help

Please help me with this

Answer 1

I ran into a similar problem. To solve it, I found two optimal options:

1. unofficial port of MJML 4 (by MailJet). Made entirely on .Net. Does not support two components (mj-include and mj-html-attributes)

2. mjml-aspnetcore - uses nodejs. Full support for the mjml standard. Should be slower than the first version, requires installation of nodejs and mjml

For first option solution will look like

var mjmlRenderer = new MjmlRenderer();
message.Body = mjmlRenderer.Render(prehtml, new MjmlOptions {
    Beautify = false
}).Html;

ps. I apologize that the solution is not complete - copying code examples from github is a bad in my opinion.
