@bdwm/bdwm-wp-env v1.6.0

A zero-config, self contained local WordPress environment for development and testing. Based on wp-env

bdwm-wp-env

bdwm-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.

Quick (tl;dr) instructions

Ensure that Docker is running, then:

$ cd /path/to/a/wordpress/plugin
$ npm -g i @bdwm/bdwm-wp-env
$ bdwm-wp-env start

The local environment will be available at http://localhost:8888 (Username: admin, Password: password).

Prerequisites

bdwm-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.

Node.js and NPM are required. The latest LTS version of Node.js is used to develop bdwm-wp-env and is recommended.

Installation

Installation as a global package

After confirming that the prerequisites are installed, you can install bdwm-wp-env globally like so:

$ npm -g i @bdwm/bdwm-wp-env

You're now ready to use bdwm-wp-env!

Installation as a local package

If your project already has a package.json, it's also possible to use bdwm-wp-env as a local package. First install bdwm-wp-env locally as a dev dependency:

$ npm i @bdwm/bdwm-wp-env --save-dev

Then modify your package.json and add an extra command to npm scripts (https://docs.npmjs.com/misc/scripts):

"scripts": {
    "bdwm-wp-env": "bdwm-wp-env"
}

When installing bdwm-wp-env in this way, all bdwm-wp-env commands detailed in these docs must be prefixed with npm run, for example:

$ npm run bdwm-wp-env start

instead of:

$ bdwm-wp-env start

Usage

Starting the environment

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:

$ bdwm-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.

Stopping the environment

To stop the local environment:

$ bdwm-wp-env stop

Troubleshooting common problems

Many common problems can be fixed by running through the following troubleshooting steps in order:

1. Check that bdwm-wp-env is running

First, check that bdwm-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.

2. Check the port number

By default bdwm-wp-env uses port 8888, meaning that the local environment will be available at http://localhost:8888.

You can configure the port that bdwm-wp-env uses so that it doesn't clash with another server by specifying the WP_ENV_PORT environment variable when starting bdwm-wp-env:

$ WP_ENV_PORT=3333 bdwm-wp-env start

Running docker ps and inspecting the PORTS column allows you to determine which port bdwm-wp-env is currently using.

You may also specify the port numbers in your .bdwm-wp-env.json file, but the environment variables take precedent.

3. Restart bdwm-wp-env

Restarting bdwm-wp-env will restart the underlying Docker containers which can fix many issues.

To restart bdwm-wp-env:

$ bdwm-wp-env stop
$ bdwm-wp-env start

4. Restart Docker

Restarting Docker will restart the underlying Docker containers and volumes which can fix many issues.

To restart Docker:

  1. Click on the Docker icon in the system tray or menu bar.
  2. Select Restart.

Once restarted, start bdwm-wp-env again:

$ bdwm-wp-env start

5. Reset the database

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:

⚠️ WARNING: This will permanently delete any posts, pages, media, etc. in the local WordPress installation.

$ bdwm-wp-env clean all
$ bdwm-wp-env start

6. Nuke everything and start again 🔥

When all else fails, you can use bdwm-wp-env destroy to forcibly remove all of the underlying Docker containers and volumes. This will allow you to start from scratch.

To nuke everything:

⚠️ WARNING: This will permanently delete any posts, pages, media, etc. in the local WordPress installation.

$ bdwm-wp-env destroy
$ bdwm-wp-env start

Command reference

bdwm-wp-env creates generated files in the bdwm-wp-env home directory. By default, this is ~/.bdwm-wp-env. The exception is Linux, where files are placed at ~/bdwm-wp-env for compatibility with Snap Packages. The bdwm-wp-env home directory contains a subdirectory for each project named /$md5_of_project_path. To change the bdwm-wp-env home directory, set the WP_ENV_HOME environment variable. For example, running WP_ENV_HOME="something" bdwm-wp-env start will download the project files to the directory ./something/$md5_of_project_path (relative to the current directory).

bdwm-wp-env start

The start command installs and initalizes the WordPress environment, which includes downloading any specified remote sources. By default, bdwm-wp-env will not update or re-configure the environment except when the configuration file changes. Tell bdwm-wp-env to update sources and apply the configuration options again with bdwm-wp-env start --update. This will not overrwrite any existing content.

bdwm-wp-env start

Starts WordPress for development on port 8888 (override with WP_ENV_PORT) and
tests on port 8889 (override with WP_ENV_TESTS_PORT). The current working
directory must be a WordPress installation, a plugin, a theme, or contain a
.bdwm-wp-env.json file. After first insall, use the '--update' flag to download updates
to mapped sources and to re-apply WordPress configuration options.

Options:
  --update   Download source updates and apply WordPress configuration.
                                                      [boolean] [default: false]

.bdwm-wp-env.json

You can customize the WordPress installation, plugins and themes that the development environment will use by specifying a .bdwm-wp-env.json file in the directory that you run bdwm-wp-env from.

.bdwm-wp-env.json supports six fields for options applicable to both the tests and development instances.

FieldTypeDefaultDescription
"core"string\|nullnullThe WordPress installation to use. If null is specified, bdwm-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"integer8888 (8889 for the tests instance)The primary port number to use for the installation. You'll access the instance through the port: 'http://localhost:8888'.
"config"ObjectSee below.Mapping of wp-config.php constants to their desired values.
"mappings"Object"{}"Mapping of WordPress directories to local directories to be mounted in the WordPress instance.

Note: the port number environment variables (WP_ENV_PORT and WP_ENV_TESTS_PORT) take precedent over the .bdwm-wp-env.json values.

Several types of strings can be passed into the core, plugins, themes, and mappings fields.

TypeFormatExample(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 Filehttp[s]://<host>/<path>.zip"https://wordpress.org/wordpress-5.4-beta2.zip"

Remote sources will be downloaded into a temporary directory located in ~/.bdwm-wp-env.

Additionally, the key env is available to override any of the above options on an individual-environment basis. For example, take the following .bdwm-wp-env.json file:

{
    "plugins": [ "." ],
    "config": {
        "KEY_1": true,
        "KEY_2": false
    },
    "env": {
        "development": {
            "themes": [ "./one-theme" ]
        },
        "tests": {
            "config": {
                "KEY_1": false
            },
            "port": 3000
        }
    }
}

On the development instance, cwd will be mapped as a plugin, one-theme will be mapped as a theme, KEY_1 will be set to true, and KEY_2 will be set to false. Also note that the default port, 8888, will be used as well.

On the tests instance, cwd is still mapped as a plugin, but no theme is mapped. Additionaly, while KEY_2 is still set to false, KEY_1 is overriden and set to false. 3000 overrides the default port as well.

This gives you a lot of power to change the options appliciable to each environment.

.bdwm-wp-env.override.json

Any fields here will take precedence over .bdwm-wp-env.json. This file is useful when ignored from version control, to persist local development overrides. Note that options like plugins and themes are not merged. As a result, if you set plugins in your override file, this will override all of the plugins listed in the base-level config. The only keys which are merged are config and mappings. This means that you can set your own wp-config values without losing any of the default values.

Default wp-config values.

On the development instance, these wp-config values are defined by default:

WP_DEBUG: true,
SCRIPT_DEBUG: true,
WP_PHP_BINARY: 'php',
WP_TESTS_EMAIL: 'admin@example.org',
WP_TESTS_TITLE: 'Test Blog',
WP_TESTS_DOMAIN: 'http://localhost',
WP_SITEURL: 'http://localhost',
WP_HOME: 'http://localhost',

On the test instance, all of the above are still defined, but WP_DEBUG and SCRIPT_DEBUG are set to false.

Additionally, the values referencing a URL include the specified port for the given environment. So if you set testsPort: 3000, port: 2000, WP_HOME (for example) will be http://localhost:3000 on the tests instance and http://localhost:2000 on the development instance.

Examples

Latest production WordPress + current directory as a plugin

This is useful for plugin development.

{
    "core": null,
    "plugins": [ "." ]
}

Latest development WordPress + current directory as a plugin

This is useful for plugin development when upstream Core changes need to be tested.

{
    "core": "WordPress/WordPress#master",
    "plugins": [ "." ]
}

Local wordpress-develop + current directory as a plugin

This is useful for working on plugins and WordPress Core at the same time.

{
    "core": "../wordpress-develop/build",
    "plugins": [ "." ]
}

A complete testing environment

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" ]
}

Add mu-plugins and other mapped directories

You can add mu-plugins via the mapping config. The mapping config also allows you to mount a directory to any location in the wordpress install, so you could even mount a subdirectory. Note here that theme-1, will not be activated, despite being the "first" mapped theme.

{
    "plugins": [ "." ],
    "mappings": {
        "wp-content/mu-plugins": "./path/to/local/mu-plugins",
        "wp-content/themes": "./path/to/local/themes",
        "wp-content/themes/specific-theme": "./path/to/local/theme-1"
    }
}

Avoid activating plugins or themes on the instance

Since all plugins in the plugins key are activated by default, you should use the mappings key to avoid this behavior. This might be helpful if you have a test plugin that should not be activated all the time. The same applies for a theme which should not be activated.

{
    "plugins": [ "." ],
    "mappings": {
        "wp-content/plugins/my-test-plugin": "./path/to/test/plugin"
    }
}

Map a plugin only in the tests environment

If you need a plugin active in one environment but not the other, you can use env.<envName> to set options specific to one environment. Here, we activate cwd and a test plugin on the tests instance. This plugin is not activated on any other instances.

{
    "plugins": [ "." ],
    "env": {
        "tests": {
            "plugins": [ ".", "path/to/test/plugin" ]
        }
    }
}

Custom Port Numbers

You can tell bdwm-wp-env to use a custom port number so that your instance does not conflict with other bdwm-wp-env instances.

{
    "plugins": [ "." ],
    "port": 4013,
    "env": {
        "tests": {
            "port": 4012
        }
    }
}
