Sixa WP Scripts

---

A small NPM module and CLI to prepare and bundle WordPress plugins into ZIP archives for easy distribution and installation.

Installation

npm i @sixa/wp-scripts --save-dev

Usage

Configure .bundleignore

Create and configure a .bundleignore in your project file to exclude files and directories from being packaged into the ZIP archive. Conceptually, .bundleignore is very similar to .gitignore and .npmignore and - essentially - works the same.

Example .bundleignore

.bundleignore
.git
.DS_Store
.editorconfig
.gitattributes
.gitignore
.husky
.idea
.prettierrc.js
.stylelintignore
.stylelintrc.js
composer.json
composer.lock
docs
node_modules
package.json
package-lock.json
phpcs.xml.dist
renovate.json
/src
*.zip

Typical Entries

Simple File Name or Path

Example:

.idea

Use a simple file name or path to exclude a specific file or directory in the project root and any subdirectory.

Wildcard + Extension

Example:

*.zip

Use a wildcard + extension to exclude any type of file in the project root and any subdirectory.

Root Folder

Example:

/src

Use a root file name or path to exclude any specific file or directory only from the project root. For instance, /src matches ./src but not ./vendor/company/package/src.

Notice

If no .bundleignore is available, @sixa/wp-scripts automatically finds and uses the .npmignore file. If no .npmignore file is present, .gitignore is used instead. If none of these files are present, no files are ignored.

Configure NPM Scripts

Add the following NPM script to your package.json:

{
  "scripts": {
    "bundle": "sixa-wp-scripts bundle NAME-OF-ARCHIVE"
  }
}

and replace NAME-OF-ARCHIVE with the name of your archive without the .zip extension.

Running sixa-wp-scripts bundle NAME-OF-ARCHIVE traverses the package directory and creates a file NAME-OF-ARCHIVE.zip including every file in the package directory without the files and directories in .bundleignore.

Preparation

Unless ignored via .bundleignore, sixa-wp-scripts bundle copies the directories node_modules and vendor into the archive. In many cases, this is the desired behaviour. However, in most cases, your local development environment will include development and peer dependencies that you do not intend to distribute in the plugin archive.

Thus, it is crucial that the bundling is prepared. Preparing the bundling process means that we eliminate all non-production dependencies from library directories. This can easily be achieved by adding an NPM script to package.json that performs the necessary steps.

The following prepare-bundle script can be used as the default script for blocks and extensions:

{
  "scripts": {
    "prepare-bundle": "npm i && npm run build && composer install --no-dev --optimize-autoloader"
  }
}

This prepare-bundle script performs the following operations:

1. Install NPM dependencies (just in case we haven't yet)
2. Build all assets
3. Reinstall composer with only production dependencies and optimize the autoloader

For blocks and extensions, rather than deleting node_modules after npm run build, we ignore node_modules in .bundleignore. Luckily, composer install --no-dev already removes all non-production dependencies from vendor and we do not need to clean up after composer. The flag --optimize-autoloader converts PSR-4 and PSR-0 rules into classmap rules, which is faster (but inconvenient during development).
