Block Hooks allow a third-party block to specify a position relative to a given block into which it will then be automatically inserted (e.g. a "Like" button block can ask to be inserted after the Post Content block, or an eCommerce shopping cart block can ask to be inserted after the Navigation block). The underlying idea is to provide an extensibility mechanism for Block Themes, in analogy to WordPress' [https://developer.wordpress.org/plugins/hooks/ Hooks] concept that has allowed extending Classic Themes through filters and actions. The two core tenets for Block Hooks are: 1. Insertion into the frontend should happen right after a plugin containing a hooked block is activated (i.e. the user isn't required to insert the block manually in the editor first); similarly, disabling the plugin should remove the hooked block from the frontend. 2. The user has the ultimate power to customize that automatic insertion: The hooked block is also visible in the editor, and the user's decision to persist, dismiss (i.e. remove), customize, or move it will be respected (and reflected on the frontend). To account for both tenets, the **tradeoff** was made to limit automatic block insertion to unmodified templates (and template parts, respectively). The reason for this is that the simplest way of storing the information whether a block has been persisted to (or dismissed from) a given template (or part) is right in the template markup. To accommodate for that tradeoff, [https://github.com/WordPress/gutenberg/pull/52969 UI controls (toggles)] are being added to increase visibility of hooked blocks, and to allow for their later insertion into templates (or parts) that already have been modified by the user. For hooked blocks to appear both in the frontend and in the editor (see tenet number 2), they need to be inserted into both the frontend markup and the REST API (templates and patterns endpoints) equally. As a consequence, this means that automatic insertion couldn't (only) be implemented at block ''render'' stage, as for the editor, the ''serialized'' (but ''unrendered'') markup needs to be modified. Furthermore, hooked blocks also have to be inserted into block patterns. Since practically no filters exist for the patterns registry, this has to be done in the registry's `get_registered` and `get_all_registered` methods. Props gziolo.

WordPress
Welcome to the WordPress development repository! Please check out the contributor handbook for information about how to open bug reports, contribute patches, test changes, write documentation, or get involved in any way you can.
Getting Started
Using GitHub Codespaces
To get started, create a codespace for this repository by clicking this 👇
A codespace will open in a web-based version of Visual Studio Code. The dev container is fully configured with softwares needed for this project.
Note: Dev containers is an open spec which is supported by GitHub Codespaces and other tools.
In some browsers the keyboard shortcut for opening the command palette (Ctrl/Command + Shift + P) may collide with a browser shortcut. The command palette can be opened via the F1 key or via the cog icon in the bottom left of the editor.
When opening your codespace, be sure to wait for the postCreateCommand to finish running to ensure your WordPress install is successfully set up. This can take a few minutes.
Local development
WordPress is a PHP, MySQL, and JavaScript based project, and uses Node for its JavaScript dependencies. A local development environment is available to quickly get up and running.
You will need a basic understanding of how to use the command line on your computer. This will allow you to set up the local development environment, to start it and stop it when necessary, and to run the tests.
You will need Node and npm installed on your computer. Node is a JavaScript runtime used for developer tooling, and npm is the package manager included with Node. If you have a package manager installed for your operating system, setup can be as straightforward as:
- macOS:
brew install node - Windows:
choco install nodejs - Ubuntu:
apt install nodejs npm
If you are not using a package manager, see the Node.js download page for installers and binaries.
Note: WordPress currently only officially supports Node.js 16.x and npm 8.x.
You will also need Docker installed and running on your computer. Docker is the virtualization software that powers the local development environment. Docker can be installed just like any other regular application.
Development Environment Commands
Ensure Docker is running before using these commands.
To start the development environment for the first time
Clone the current repository using git clone https://github.com/WordPress/wordpress-develop.git. Then in your terminal move to the repository folder cd wordpress-develop and run the following commands:
npm install
npm run build:dev
npm run env:start
npm run env:install
Your WordPress site will be accessible at http://localhost:8889. You can see or change configurations in the .env file located at the root of the project directory.
To watch for changes
If you're making changes to WordPress core files, you should start the file watcher in order to build or copy the files as necessary:
npm run dev
To stop the watcher, press ctrl+c.
To run a WP-CLI command
npm run env:cli -- <command>
WP-CLI has many useful commands you can use to work on your WordPress site. Where the documentation mentions running wp, run npm run env:cli -- instead. For example:
npm run env:cli -- help
To run the tests
These commands run the PHP and end-to-end test suites, respectively:
npm run test:php
npm run test:e2e
To restart the development environment
You may want to restart the environment if you've made changes to the configuration in the docker-compose.yml or .env files. Restart the environment with:
npm run env:restart
To stop the development environment
You can stop the environment when you're not using it to preserve your computer's power and resources:
npm run env:stop
To start the development environment again
Starting the environment again is a single command:
npm run env:start
Credentials
These are the default environment credentials:
- Database Name:
wordpress_develop - Username:
root - Password:
password
To login to the site, navigate to http://localhost:8889/wp-admin.
- Username:
admin - Password:
password
Note: With Codespaces, open the portforwarded URL from the ports tab in the terminal, and append /wp-admin to login to the site.
To generate a new password (recommended):
- Go to the Dashboard
- Click the Users menu on the left
- Click the Edit link below the admin user
- Scroll down and click 'Generate password'. Either use this password (recommended) or change it, then click 'Update User'. If you use the generated password be sure to save it somewhere (password manager, etc).
