There are few steps necessary to prepare a plugin for release on the WordPress.org plugin directory. We use Gulp to automate this.

1. Download and install Node.js and npm.
2. Install gulp using npm install -g gulp.
3. In the plugin folder, ensure the plugin-build repository has been added as a submodule in a folder called 'build' and is up to date. This can be done using git submodule add git@github.com:siteorigin/plugin-build.git build.
4. In a terminal, navigate to the build directory in the plugin and run npm install. When using plugin-build in the SiteOrigin CSS plugin, npm-install should be run in both the SiteOrigin CSS plugin folder and the build folder.
5. Get some coffee while npm installs the required packages.

Each plugin has it's own slug and different files needed for a build. So any plugin that uses this build is required to have a configuration file called build-config.js in the root of the plugin directory. This file is in the form of an npm module which simply returns a configuration object used by the gulpfile to determine the files and folders needed for the build. Below is an excerpt from the SiteOrigin CSS Editor plugin build-config.js file:

module.exports = {
    slug: 'so-css',
    jsMinSuffix: '.min',
    version: {
        src: [
            'so-css.php',
            'readme.txt'
        ]
    },
    less: {
        src:['css/**/*.less'],
        include:[]
    },
};

There are two build tasks, build:release and build:dev.

The release task performs the following subtasks:

1. Updates the version number in the required files.
2. Compiles required SASS and LESS files to CSS.
3. Minifies required JavaScript files and adds the suffix specified in the build-config.js file.
4. Copies all files to a dist/ folder.
5. Creates a .zip archive with the appropriate filename ready for uploading to wordpress.org.

Release task usage:

gulp build:release -v {version}

Where {version} should be replaced with the required version number. For example, say the next version of the plugin is 1.2.3:

gulp build:release -v {1.2.3}

The dev build task only has one subtask:

1. Watch LESS and/or SASS files for changes and compile to CSS.

This is simply to avoid having to manually recompile LESS/SASS files while working on them.

gulp updateGoogleFonts ---apiKey {YOUR_API_KEY} The task will require an update to the build-config file in each plugin to specify the name and location of the fonts file.
