Annoucement from Engineering @ Faire

Hello mjml community, we at Faire are excited to announce we will be taking over maintaining the open-source mjml-react project!

Over the past year, Faire has used mjml-react extensively. This package allowed us to incorporate all the benefits of mjml without having to ask our developers to learn a new dev environment when moving from web to email. As a result, we significantly reduced the development effort for creating emails, while keeping email rendering issues to a minimum.

We saw so much benefit from mjml-react, and we don’t want to see it go. That is why we want to continue to maintain the package, and improve it with some of our own new ideas! For now you can check us out at @faire/mjml-react. We hope this can be a drop-in replacement for mjml-react in most cases, but are eager to work with you if there are any issues. Don’t hesitate to reach out to us on the #mjml-react channel in the MJML Slack Group or file a github issue. From there, you can look forward to new improvements coming soon.

And of course we want to extend a massive thank you to the Wix team for building and previously maintaining this project.

mjml-react ·

There is an awesome library mjml with github repo here https://github.com/mjmlio/mjml.

MJML is a markup language created by Mailjet. So in order to create emails on the fly we created a library with React components.

How it works

Install the required dependencies first:

npm install react react-dom mjml @faire/mjml-react

And afterwards write a code like a pro:

import {
  render,
  Mjml,
  MjmlHead,
  MjmlTitle,
  MjmlPreview,
  MjmlBody,
  MjmlSection,
  MjmlColumn,
  MjmlButton,
  MjmlImage,
} from "@faire/mjml-react";

const { html, errors } = render(
  <Mjml>
    <MjmlHead>
      <MjmlTitle>Last Minute Offer</MjmlTitle>
      <MjmlPreview>Last Minute Offer...</MjmlPreview>
    </MjmlHead>
    <MjmlBody width={500}>
      <MjmlSection fullWidth backgroundColor="#efefef">
        <MjmlColumn>
          <MjmlImage src="https://static.wixstatic.com/media/5cb24728abef45dabebe7edc1d97ddd2.jpg" />
        </MjmlColumn>
      </MjmlSection>
      <MjmlSection>
        <MjmlColumn>
          <MjmlButton
            padding="20px"
            backgroundColor="#346DB7"
            href="https://www.wix.com/"
          >
            I like it!
          </MjmlButton>
        </MjmlColumn>
      </MjmlSection>
    </MjmlBody>
  </Mjml>,
  { validationLevel: "soft" }
);

And as the result you will get a nice looking email HTML (works in mobile too!)

Options

@faire/mjml-react sets the following MJML options when rendering to HTML:

{
  keepComments: false,
  beautify: false,
  minify: true,
  validationLevel: 'strict'
}

If you want to override these, you can pass an object to render as a second argument. See the MJML docs for the full list of options you can set.

Extensions

import {
  MjmlHtml,
  MjmlComment,
  MjmlConditionalComment
} from '@faire/mjml-react/extensions';

<MjmlComment>Built with ... at ...</MjmlComment>
// <!--Built with ... at ...-->

<MjmlConditionalComment>MSO conditionals</MjmlConditionalComment>
// <!--[if gte mso 9]>MSO conditionals<![endif]-->

<MjmlConditionalComment condition="if IE">MSO conditionals</MjmlConditionalComment>
// <!--[if IE]>MSO conditionals<![endif]-->

<MjmlHtml tag="div" html="<span>Hello World!</span>" />
// <div><span>Hello World!</span></div>

Utils

We do have also some utils for post processing the output HTML. Because not all mail clients do support named HTML entities, like '. So we need to replace them to hex.

import {
  namedEntityToHexCode,
  fixConditionalComment,
} from "@faire/mjml-react/utils";

const html = "<div>&apos;</div>";
namedEntityToHexCode(html);
// <div>&#39;</div>

fixConditionalComment(
  "<!--[if mso]><div>Hello World</div><![endif]-->",
  "Hello",
  "if IE"
);
// <!--[if IE]><div>Hello World</div><![endif]-->
