generator-gulp-sgalinski

NOTE: This project is deprecated and will not be developed any further. The gulp-toolchain is now integrated into sgc (sgalinski cli).

Installation

To use the sgalinski-generator you need to have node and npm installed. Furthermore, you should have yeoman and gulp installed globally. To do so, simply run

npm install -g yo
npm install -g gulp

Finally, to install the generator, run

npm install -g generator-gulp-sgalinski

Usage

To run the generator, navigate to the directory you want to create your project in and run

yo gulp-sgalinski

This will generate all the files you need to run the toolchain, including a config.json file which you will have to adapt to your needs.

Here is what you get in detail:

• gulp | this folder contains the gulp tasks, split into several files, as well as the config.json
• gulpfile.js | The entry point for gulp
• package.json | The package file that contains all needed Node dependencies
• npm-shrinkwrap.json | This file contains all required dependencies, locked down to a specific version number (learn more)
• install.sh | you can execute this file to ensure a proper installation of the toolchain. It will set up the correct version of Node, Gulp and the toolchain.
• .editorconfig | Editorconfig is a great common way to synchronize editor settings across projects and IDEs/Editors. You can simply remove it, if you don't want to use it.
• .jshintrc | The configuration file for jshint
• .scss-lint.yml | The configuration file for Scss-Linters

The install script

Since version 4.0.0, the toolchain comes with an installation shell-script. The purpose of this script is to easily set up the correct version of Node and gulp and to install the toolchains dependencies in one single step.

While this might not seem important during the initial creation of a project, it is rather handy when setting up the development environment at another machine. After checking out the repository of your project, your fellow co-workers will simply have to execute the install.sh in order to get the toolchain up and running.

Useful tasks

Updating / Installing the toolchains dependencies

This task will also be executed by the install.sh script

In order for the toolchain to work, you need to install all its dependencies. To do so, you can simply run the update task (this will also work for the initial installation). Please note that you need to go to the website root (e.g. web/website-base.dev/) in order to execute this command.

npm run toolchain:update

This task will delete all previously installed dependencies and pull in the new ones.

Upgrading the toolchain

Caution! This task is only meant for finishing up a new release of the toolchain itself.

To upgrade all dependencies and rewrite the npm-shrinkwrap, run the following command:

npm run toolchain:upgrade

The upgrade task will delete all dependencies, remove the current shrinkwrap and then install the new dependencies (as stated in package.json) and create a new shrinkwrap.

If you run this task, make sure that you know what you're doing, as updating dependencies can break stuff if not propperly tested!

Configuration

To adjust the toolchain to a certain project, there is a config.json file where the following options can be configured:

directories

Holds the paths to the css, sass, javascript, images, sprites and inline-svgs, relative to the extensions root.

abovethefold

Configuration for the critical path css.

• template: path to the src template
• dest: path to the destination

js

• libraryPaths: additional locations that should be searched when resolving CommonJS requires
• excludeFromQa: *glob patterns with locations that hold JavaScript that does not need to be linted (vendor stuff)

images

• optimize: locations of user uploaded images that should be optimized

extensions

A list of extensions that should be included in the watch task. Please note, that the very first extension in this list is expected to be your project_theme.

Usage

You can run a specific task on a specific component, or start a watcher that will fire up BrowserSync and run tasks when source files change. Extensions that will be watched are defined in config.json.

If you run a specific task, you need to specify the extension you want the task to run on with the --ext parameter.

gulp css --ext project_base

There are a few available tasks you need to remember:

default/watch task

gulp

Starts a project wide watcher that will trigger the css/javascript task when you change any .scss, or .js-file and opens the website in your browser, as a browsersync session (changed js and css will automatically get injected when recompiled).

Hint: If you already have a browsersync instance open in your browser, you can pass the argument -s to restart the session without opening a browser.

sprite task

gulp sprites --ext [extensions name]

Triggers sprite generation inside the given directory.

Assumptions:

• all sprite images are inside images/sprites, relative to the given path.
• all sprite images are PNGs.
• there is a sass directory, next to the images folder.

This task will generate a png inside the images folder, containing all the sprites and a .scss file inside the sass folder, which will provide the necessary mixins. To use the sprites inside your SASS code, import the _sprite.scss file. You can then use the following mixins:

// will output css for a sprite image 'box.png' 
.element {
    @sprite ($box);
}

The @sprite mixin already contains width and height. If you need these values for something else, use the @sprite-width and @sprite-height mixins.

css task

gulp css --ext [extension name]

Triggers css compilation inside the given directory. Note, that this task will also run the sprite task before it starts.

Assumptions:

• all scss files are inside the sass directory, relative to the given path.
• all css files go into the stylesheets directory, relative to the given path.

images task

gulp images --ext [extension name]

Optimizes all images for the given path.

Assumptions:

• all images are inside the image directory, relative to the given path.

optimize images in fileadmin and uploads

gulp images:uploaded

This task optimizes all images (png, jpg, gif) inside the folders you specified in the config.json file. You might want to run this task on a regular basis to compress user uploaded media.

Troubleshooting

Strange errors during npm install

If you get strange errors during npm install, it might help to clear the npm cache. To do so, run 'npm cache clean', oder simply delete the .npm directory inside your home folder.
