This is my – Josh Pollock – opinionated boilerplate and template for WordPress plugin with PSR-4 autoloader, TypeScript, Docker, Github actions, and other fun stuff.

Creating A Plugin

This plugin is a template. You can create a new Github project from this repo using the “Use This Template” button, or by downloading the plugin from Github.

There is a CLI for renaming things, or you can rename things manually.

Notes:

• When you first install with Yarn, many packages will prompted for what version to install, choose the latest.

Rename With ClI

You can create two different versions of the plugin, using the CLI

Everything

This option includes everything: local dev, Typescript, composer autoloader, PHP tests, JavaScript tests, etc.

• Create a new git repo based on this template.
• Clone that repo locally
• Install
  • yarn
• Rename plugin and update translation domain, fucnction prefix, namespace, etc.
  • yarn rename

Basic

This version has less things, it does not use Yarn workspace or Typescript or composer. It generates one PHP file that can load JS/CSS and a WordPress-friendly webpack that can have any number of entry points.

• Copy or clone this repo locally.
  • git clone git@github.com:Shelob9/wordpress-plugin.git
• Install
  • yarn
• Rename plugin and update translation domain, function’s prefix, namespace, etc.
  • yarn rename:basic
• This will create a directory named for your plugin slug.
  • Copy that somewhere else.
  • Delete everything else.
• Switch to directory with the new plugin in it
• Install
  • yarn
• Build
  • yarn build

Manual Renaming

After making your own version, I recommend you follow these steps, before running composer install:

1. Choose a slug, and root namespace for your plugin.
2. Change main plugin file’s name from wordpress-plugin.php to match your plugin slug.
3. Find and replace, with case sensitivity, “wordpress-plugin” with your plugin’s slug in all files.
   • Text domain
   • Plugin name in package.json and composer.json
   • tests/bootstrap.php includes main plugin file.
4. In composer.json change Josh\\WordPressPlugin\\ in both autoloader to match your new root namespace.
5. Find and replace WordPressPlugin in php files with your root namespace.
6. Fine and replace shelob9.gihub.io with your Github pages site URL.
7. Enable Github pages for your repo.
   • Now you have a documentation site!
