Are you tired of wrestling with HTML tables and inline styles to create responsive email templates? Do you wish there was a way to separate your presentation layer from your business logic? Look no further! In this article, we’ll explore the powerful combination of MJML and Freemarker, a match made in heaven for generating dynamic email templates.
What is MJML?
MJML (Mailjet Markup Language) is a lightweight, open-source markup language designed specifically for generating responsive email templates. It’s a declarative language that abstracts away the complexity of HTML and CSS, making it easy to create beautiful, mobile-friendly emails without sacrificing design or usability.
Example MJML code:
Hello, World!
What is Freemarker?
Freemarker is a popular, open-source templating engine that allows you to separate your presentation layer from your business logic. It’s a template engine that enables you to generate dynamic content by injecting data into templates, making it an ideal choice for generating emails.
Example Freemarker code:
<#assign name = "John Doe">
<p>Hello, ${name}!</p>
Why MJML with Freemarker?
- Separation of Concerns: By using MJML for layout and design, and Freemarker for data injection, you can maintain a clean separation of concerns between your presentation layer and business logic.
- Faster Development: MJML’s declarative syntax and Freemarker’s templating capabilities enable rapid development and prototyping of email templates.
- Improved Readability: MJML’s concise syntax and Freemarker’s syntax highlighting make your code more readable and maintainable.
Setting up MJML with Freemarker
To get started with MJML and Freemarker, you’ll need to install the necessary dependencies and configure your environment. Here’s a step-by-step guide:
- Install the MJML compiler using npm or yarn:
npm install --save mjmloryarn add mjml - Install the Freemarker template engine using Maven or Gradle:
mvn install freemarkerorgradle install freemarker - Create a new Java class to handle Freemarker configuration and data injection:
public class FreemarkerConfig { ... } - Create an MJML template file (e.g., `template.mjml`) and populate it with MJML markup.
- Create a Freemarker template file (e.g., `template.ftl`) and populate it with Freemarker syntax.
Generating Dynamic Email Templates with MJML and Freemarker
Now that you’ve set up your environment, let’s create a simple email template that demonstrates the power of MJML and Freemarker. We’ll create a template that displays the user’s name and a personalized message.
Example MJML template:
<mjml>
<mj-body>
<mj-section>
<mj-column>
<mj-text>Hello, ${name}!</mj-text>
<mj-text>Your personalized message: ${message}</mj-text>
</mj-column>
</mj-section>
</mj-body>
</mjml>
Example Freemarker template:
<#assign name = "John Doe">
<#assign message = "Welcome to our newsletter!">
<mjml>
<mj-body>
<mj-section>
<mj-column>
<mj-text>Hello, ${name}!</mj-text>
<mj-text>Your personalized message: ${message}</mj-text>
</mj-column>
</mj-section>
</mj-body>
</mjml>
In the Freemarker template, we’ve assigned values to the `name` and `message` variables. When we inject these values into the MJML template, Freemarker replaces the placeholders with the actual values, generating a dynamic email template.
