Similarly to the first header, you will have to center the text both vertically and horizontally. To add the image header, you will have to replace the section’s background-color with a background-url. We’ll also have a call to action button that points to a page with more details. In this section, we’ll have a background image and a block of text, which should represent our company slogan. The mj-text component is for our text content and takes styling attributes like font-style, font-size, color, etc. The mj-column component is used to define a column. This section of our email will only contain our company/brand name in a center banner position: This helps our readers to easily identify sections of our email. mj-body defines the starting point of our email, and mj-section defines a section to contain other components.įor each section defined, a background-color attribute with their respective hex value is also defined. In our email.mjml file: įrom the above, you can see we’re making use of two MJML components: mj-body and mj-section. As seen above, our email will be divided into six sections. The sections serve as the skeleton for our responsive email. Now that we’ve created the file, our responsive email will be divided into the following sections: To get started, create a file named email.mjml, although you can also choose any other name you’d like. You can install MJML with npm to use it with Node.js or the CLI: $ npm install -g mjml In this tutorial, we’ll be building beautiful and responsive emails with MJML and testing across several email clients. It is also feature-rich, with standard components that speed up development time. Its semantic syntax makes it easy and straightforward to use. This markup language is designed to reduce the pain of coding responsive emails. MJML is a modern email tool that allows developers to create great emails that are beautiful and responsive across all devices and mail clients. Reflection-free Run-Time Dependency Injection framework for Go 1.Ogundipe Samuel Follow Software engineer and technical writer. Simple CLI tool to get the feed URL from Apple Podcasts links, for easier use in podcatchers Yet another way to use c/asm in golang, translate asm to goasm If you’ve created a library for another language, please let us know, so that we can add it to this list! GitHubĪ set of libraries in Go and boilerplate Golang code for building scalable software-as-a-service (SaaS) applications Since the MJML library is compiled into a WebAssembly module, it should be relatively easy to take the compiled module andĭrop it into languages with WebAssembly environments. Run docker compose run build-wasm from the root of the repository. You can run tests using docker by running docker compose run test from the root of the repository. In the current implementation of mjml, it is not possible to customize the output of js-beautify.Therefore, to prepare for this move, the wrapper imports html-minifierĪnd js-beautify directly to support minifying and beautifying the output. Beautify and minify will be removed from the library in MJML5 and will be.log ( jsonToXML ( mjml ) ) Differences from the MJML JavaScript library Input := `Hello World` output, err := mjml. This means that the library is thread-safe and you can use it concurrently in multiple goroutines. Idle instances are automatically destroyed and will be re-created when WorkersĪs WebAssembly modules compiled using Javy are not thread-safe and cannot be called concurrently, the library maintainsĪ pool of 1 to 10 instances to perform compilations. On application start up to accept input in order to compile MJML into HTML. The WebAssembly module is then compressed using Brotli to yield a 10x reduction inĭuring runtime, the module is decompressed and loaded into a Wazero runtime This wrapper is then bundled using webpack and compiled into a WebAssembly module using Suborbital’s Javy fork,Ī Javascript to WebAssembly compiler. We wrote a simple JavaScript wrapper that wraps around the MJML library by accepting input and returning output This is why we built mjml-go and created an idiomatic Go API to compile MJML into HTML directly in Go applications thatĬan be deployed as a single Go binary. In addition, running these extra servers introduces extra moving parts The deployed Node.js servers, applications calling these servers will need to be upgraded in a synchronized This approach poses some certain challenges, for example, if MJML is upgraded to a new major version in The usual approach is to wrap the library in a Node.js HTTP server and provide an endpoint through whichĪpplications not written in JavaScript can make HTTP requests to compile MJML into HTML. Compile MJML into HTML directly in your Go application! Why?
