Magento 2 Frontend Development Workflow

3.1. NMP and Grunt

Grunt is a tool to build code as well as automate repetitive tasks (task runner) such as compressing, compiling CSS files, javascript, and running unit tests. This is a must-have tool for every Magento 2 front-end developer. 

The reason is due to the rich Grunt ecosystem, a large number of plugins, and good support for automatic running of tasks, especially Compile LESS file with Grunt when CSS is not updated outside the front end.

Install NMP somehow ( for valet users on mac os you can do brew install NMP). After NMP install, you’ll be able to use Grunt. 

In the root of your Magento store, You can follow these instructions to set up a front end workflow: Compile LESS using Grunt

3.2. A word about “client-side vs server-side” rendering

In the Magento application, there are 2 modes of compiling .less files to CSS are implemented:

  1. Server-side Less compilation.

This is the default compilation mode, the compilation is done on the server, using the Less PHP library.

  1. Client-side Less compilation.

This mode allows you to tell Magento to compile .less files in the browser using the native less.js library. 

The client’s workflow is quite similar to the server’s. However, since the LESS files on the client are compiled after each page reload, it can generate too large JS files and degrade the store’s performance.

Compilation mode setup steps:

Step 1: Login to admin panel, go to Store > Settings > Configuration > ADVANCED > Developer.

Step 2: Open the Store View drop-down menu > Default configuration option.

Step 3: Expand Frontend development workflow section > Workflow Type field > select compile mode

Step 4: Save the changes.

3.3. Developer mode vs production mode.

3.3.1. Developer mode

This mode is usually used when you are extending or customizing Magento mode.

3.3.2. Production mode

This mode is typically used when it is deployed to a production server after optimizing the server environment.

Providing all required static files instead of forcing Magento to dynamically locate and copy static files as required at runtime improves performance significantly

3.4. Grunt commands: exec, less, watch

First, configure your custom theme 



  • Grunt exec
  • Grunt less
  • Grunt watch

If you add or remove a file, or update an @import you must run these: Grunt exec, bin/magento cache: clear and run the watch (or less) command 

And we will be using grunt commands when we are in the development mode, not in production mode.

3.5. @importing

@magento_import is a Magento-specific LESS directive. It is used to gather files with the same name from different locations or different modules. The @import directive includes a single file found under the static file fallback.

@magento_import can only be used in the theme’s source files.

3.6. Mobile-first and breakpoints.

Mobile-first means your mobile styles are written first, with no media query. Then you write tablet, desktop, whatever larger ones in min-width media queries.

In Magento 2 you should not use normal media queries. Magento splits mobile and desktop styles into 2 files l-styles.css and m-styles.css. So, you have to use the Magento media queries to make them show in the right files.

3.7. Adding tablet layout to a theme that extends from Luma or Blank.

Luma and blank only have breakpoints for desktop and mobile, so adding a tablet layout can be tricky. Because they switch from mobile to desktop. So, you want to make a custom mixin (less “function”) and add it to your responsive.less file inside of @media-target = ‘mobile’.

3.8. Magento media queries 

The themes Blank and Luma are based on UI Magento libraries. This UI library uses CSS3 media queries, an extension of the @Media rule to adjust the layout with the width of the screen and compare it with the media query condition.

3.9. Extras:— Fontello.— SVG Icons vs font icons.

Fontello is an open community project that allows the Developer to use free fonts on their list. It allows you to choose from thousands of different icons and download them to create your own font package.

SVG icon vs font icon: which is better? 

It is an ending question for the past decade. Simply say, creating ahead icons is great for developers and it has many advantages such as moving quickly and putting the icon on the website. But if you have like a big-budget and you want everything to be done perfectly, the SVG icon is the way to go.

In addition, you cannot upload SVG to Magento. It is like a security problem. Therefore, it must be made from the theme website or you have to add a module.
