wp-env
lets you easily set up a local WordPress environment for building and testing plugins and themes. It's simple to install and requires no configuration.
Ensure that Docker is running, then:
$ cd /path/to/a/wordpress/plugin
$ npx wp-env start
The local environment will be available at http://localhost:8888.
wp-env
requires Docker to be installed. There are instructions available for installing Docker on Windows 10 Pro, all other versions of Windows, macOS, and Linux.
After confirming that Docker is installed, you can install wp-env
globally like so:
$ npm -g i @wordpress/env
You're now ready to use wp-env
!
First, ensure that Docker is running. You can do this by clicking on the Docker icon in the system tray or menu bar.
Then, change to a directory that contains a WordPress plugin or theme:
$ cd ~/gutenberg
Then, start the local environment:
$ wp-env start
Finally, navigate to http://localhost:8888 in your web browser to see WordPress running with the local WordPress plugin or theme running and activated. Default login credentials are username: admin
password: password
.
To stop the local environment:
$ wp-env stop
Many common problems can be fixed by running through the following troubleshooting steps in order:
First, check that wp-env
is running. One way to do this is to have Docker print a table with the currently running containers:
$ docker ps
In this table, by default, you should see three entries: wordpress
with port 8888, tests-wordpress
with port 8889 and mariadb
with port 3306.
By default wp-env
uses port 8888, meaning that the local environment will be available at http://localhost:8888.
You can configure the port that wp-env
uses so that it doesn't clash with another server by specifying the WP_ENV_PORT
environment variable when starting wp-env
:
$ WP_ENV_PORT=3333 wp-env start
Running docker ps
and inspecting the PORTS
column allows you to determine which port wp-env
is currently using.
You may also specify the port numbers in your .wp-env.json
file, but the environment variables take precedent.
Restarting wp-env
will restart the underlying Docker containers which can fix many issues.
To restart wp-env
:
$ wp-env stop
$ wp-env start
Restarting Docker will restart the underlying Docker containers and volumes which can fix many issues.
To restart Docker:
- Click on the Docker icon in the system tray or menu bar.
- Select Restart.
Once restarted, start wp-env
again:
$ wp-env start
Resetting the database which the local environment uses can fix many issues, especially when they are related to the WordPress installation.
To reset the database:
$ wp-env clean all
$ wp-env start
When all else fails, you can try forcibly removing all of the underlying Docker containers and volumes, the underlying WordPress directory, and starting again from scratch.
To nuke everything:
$ docker rm -f $(docker ps -aq)
$ docker volume rm -f $(docker volume ls -q)
$ rm -rf "../$(basename $(pwd))-wordpress"
$ wp-env start
wp-env
creates generated files in the wp-env
home directory. By default, this is ~/.wp-env
. The exception is Linux, where files are placed at ~/wp-env
for compatibility with Snap Packages. The wp-env
home directory contains a subdirectory for each project named /$md5_of_project_path
. To change the wp-env
home directory, set the WP_ENV_HOME
environment variable. For example, running WP_ENV_HOME="something" wp-env start
will download the project files to the directory ./something/$md5_of_project_path
(relative to the current directory).
wp-env start
Starts WordPress for development on port 8888 (http://localhost:8888)
(override with WP_ENV_PORT) and tests on port 8889 (http://localhost:8889)
(override with WP_ENV_TESTS_PORT). The current working directory must be a
WordPress installation, a plugin, a theme, or contain a .wp-env.json file.
Positionals:
ref A `https://github.com/WordPress/WordPress` git repo branch or commit for
choosing a specific version. [string] [default: "master"]
wp-env stop
Stops running WordPress for development and tests and frees the ports.
wp-env clean [environment]
Cleans the WordPress databases.
Positionals:
environment Which environments' databases to clean.
[string] [choices: "all", "development", "tests"] [default: "tests"]
wp-env run <container> [command..]
Runs an arbitrary command in one of the underlying Docker containers, for
example it's useful for running wp cli commands.
Positionals:
container The container to run the command on. [string] [required]
command The command to run. [array] [default: []]
For example:
wp-env run cli wp user list
⠏ Running `wp user list` in 'cli'.
ID user_login display_name user_email user_registered roles
1 admin admin [email protected] 2020-03-05 10:45:14 administrator
✔ Ran `wp user list` in 'cli'. (in 2s 374ms)
docker logs -f <container_id> >/dev/null
Shows the error logs of the specified container in the terminal. The container_id is the one that is visible with `docker ps -a`
You can customize the WordPress installation, plugins and themes that the development environment will use by specifying a .wp-env.json
file in the directory that you run wp-env
from.
.wp-env.json
supports five fields:
Field | Type | Default | Description |
---|---|---|---|
"core" |
string|null |
null |
The WordPress installation to use. If null is specified, wp-env will use the latest production release of WordPress. |
"plugins" |
string[] |
[] |
A list of plugins to install and activate in the environment. |
"themes" |
string[] |
[] |
A list of themes to install in the environment. The first theme in the list will be activated. |
"port" |
integer |
8888 |
The primary port number to use for the insallation. You'll access the instance through the port: 'http://localhost:8888'. |
"testsPort" |
integer |
8889 |
The port number to use for the tests instance. |
"config" |
Object |
"{ WP_DEBUG: true, SCRIPT_DEBUG: true }" |
Mapping of wp-config.php constants to their desired values. |
Note: the port number environment variables (WP_ENV_PORT
and WP_ENV_TESTS_PORT
) take precedent over the .wp-env.json values.
Several types of strings can be passed into the core
, plugins
, and themes
fields:
Type | Format | Example(s) |
---|---|---|
Relative path | .<path>|~<path> |
"./a/directory" , "../a/directory" , "~/a/directory" |
Absolute path | /<path>|<letter>:\<path> |
"/a/directory" , "C:\\a\\directory" |
GitHub repository | <owner>/<repo>[#<ref>] |
"WordPress/WordPress" , "WordPress/gutenberg#master" |
ZIP File | http[s]://<host>/<path>.zip |
"https://wordpress.org/wordpress-5.4-beta2.zip" |
Remote sources will be downloaded into a temporary directory located in ~/.wp-env
.
Any fields here will take precedence over .wp-env.json. This file is useful, when ignored from version control, to persist local development overrides.
This is useful for plugin development.
{
"core": null,
"plugins": [ "." ]
}
This is useful for plugin development when upstream Core changes need to be tested.
{
"core": "WordPress/WordPress#master",
"plugins": [ "." ]
}
This is useful for working on plugins and WordPress Core at the same time.
{
"core": "../wordpress-develop/build",
"plugins": [ "." ]
}
This is useful for integration testing: that is, testing how old versions of WordPress and different combinations of plugins and themes impact each other.
{
"core": "WordPress/WordPress#5.2.0",
"plugins": [ "WordPress/wp-lazy-loading", "WordPress/classic-editor" ],
"themes": [ "WordPress/theme-experiments" ]
}
You can tell wp-env
to use a custom port number so that your instance does not conflict with other wp-env
instances.
{
"plugins": [ "." ],
"port": 4013,
"testsPort": 4012
}
