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.
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.
brew install node
choco install node
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
WP-CLI commandTo run a
npm run env:cli <command>
WP-CLI has a lot of useful commands you can use to work on your WordPress site. Where the documentation mentions running
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
.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
These are the default environment credentials:
