Why Use Snowdog Frontools?

Using Snowdog Frontools can significantly reduce compilation time and improve the efficiency of your development workflow. It also supports advanced features like automatic reloading, better organization of stylesheets, and integration with modern frontend technologies.

Setting Up Snowdog Frontools

Prerequisites

Before diving into the setup, ensure you have the following prerequisites:

  • Node.js and npm (Node Package Manager)
  • Magento 2 installation
  • Basic knowledge of SCSS and Frontend Development

Installation Steps

  1. Install Node.js and npm: If you haven't installed Node.js, you can download it from nodejs.org. Installing Node.js will also install npm.

  2. Clone Snowdog Frontools Repository: Navigate to your Magento installation directory and clone the Snowdog Frontools repository.

    git clone https://github.com/SnowdogApps/magento2-frontools.git

  3. Install Dependencies: Navigate to the Frontools directory and install all required npm packages.

    cd magento2-frontools
npm install

  4. Configure Frontools: Create a themes.json file in the Frontools directory if it doesn't already exist. This file will define your theme configurations.

Writing Your Custom SCSS

Creating SCSS Files

To create a custom module SCSS file, follow these steps:

  1. Create the SCSS File: Add your SCSS file in the module directory. The path should be app/code/Vendor/Modulename/view/frontend/web/css/_module.scss.

  2. Update themes.json: Ensure that your themes.json includes the path to your custom SCSS file. The configuration might look something like this:

    {
  "theme": {
    "src": "vendor/snowdog/theme-blank-sass",
    "dest": "pub/static/frontend/Vendor/theme",
    "locale": ["en_US"]
  },
  "blacklist": [
    "**/_module.scss"
  ]
}

Importing the SCSS

In your main SCSS file (typically styles.scss), import the custom module SCSS:

@import 'modulename/web/css/module';

Compiling Your SCSS Files

Running the Compilation

Now that you have your SCSS files set up and referenced correctly, you can compile them using Snowdog Frontools. Use the following command:

gulp styles

Verifying the Compilation

To check if the SCSS file compiled successfully, navigate to the var/view_preprocessed/frontools directory. You should see your compiled CSS files in this location.

Common Issues and Troubleshooting

File Not Found in Compiled Output

If you don't see your SCSS file in the compiled output, make sure:

  • The file path is correct and matches the configuration in themes.json.
  • There are no syntax errors in your SCSS file.

Compilation Errors

If you encounter errors during compilation:

  • Check the console output for specific error messages.
  • Validate the SCSS syntax and ensure all necessary variables and mixins are defined.
