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

Getting Started

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.

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

npm install npm run build:dev npm run env:start npm run env:install

Your WordPress site will 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 watch

To stop the watcher, press ctrl+c. To run a WP-CLI command

npm run env:cli

WP-CLI has a lot of 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

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).
