DDEV for Craft CMS Development

Companion Skills — Always Load Together

When this skill triggers, also load:

• craftcms — Plugin/module development. Required when DDEV commands involve Craft CLI (ddev craft make, ddev craft migrate, ddev craft project-config).
• craft-php-guidelines — PHP coding standards. Required when DDEV commands involve code quality tooling (ddev composer check-cs, ddev composer phpstan, ddev craft pest/test).

Documentation

• DDEV docs: https://docs.ddev.com/en/stable/
• Craft CMS quickstart: https://docs.ddev.com/en/stable/users/quickstart/#craft-cms
• Configuration reference: https://docs.ddev.com/en/stable/users/configuration/config/
• Custom commands: https://docs.ddev.com/en/stable/users/extend/custom-commands/
• Additional services: https://docs.ddev.com/en/stable/users/extend/additional-services/
• Vite integration: https://docs.ddev.com/en/stable/users/usage/developer-tools/#nodejs

When unsure about a DDEV feature, WebFetch the relevant docs page.

Common Pitfalls

• Using ddev exec composer install instead of ddev composer install — DDEV shorthand commands handle path resolution and environment setup. Always use the shorthand.
• Forgetting ddev craft up does both migrate/all and project-config/apply — no need to run them separately after pulls or deploys.
• Exposing the Vite dev server with ports instead of web_extra_exposed_ports — ports causes conflicts when running multiple DDEV projects. web_extra_exposed_ports routes through Traefik and works with HTTPS.
• Running ddev composer global require — global packages install inside the container and vanish on restart. Install project-level dependencies only.
• Setting nodejs_version but running npm install on the host — Node must run inside the container via ddev npm to match the configured version.
• Editing .ddev/config.yaml while containers are running without restarting — changes to config require ddev restart to take effect.
• Using ddev import-db without --target-db=db on multi-database setups — the default target is db, but if you've configured additional databases, be explicit.
• Adding #ddev-generated to custom commands you've customized — DDEV overwrites files with this comment during updates. Only use it for add-on-managed commands. Custom commands you maintain should omit it.

Shorthand Commands

Always use DDEV shorthand over ddev exec:

ddev composer install          # not ddev exec composer install
ddev craft up                  # not ddev exec php craft up
ddev npm install               # not ddev exec npm install
ddev craft make service        # scaffolding

Craft CMS Project Type

# .ddev/config.yaml
name: my-craft-site
type: craftcms
docroot: web
php_version: "8.3"
database:
  type: mysql
  version: "8.0"
nodejs_version: "20"

DDEV auto-injects: CRAFT_DB_SERVER, CRAFT_DB_USER, CRAFT_DB_PASSWORD, CRAFT_DB_DATABASE, PRIMARY_SITE_URL.

Common Commands

ddev start                     # Start the project
ddev stop                      # Stop the project
ddev restart                   # Restart containers
ddev ssh                       # SSH into web container
ddev describe                  # Show project info and URLs
ddev logs                      # View container logs
ddev import-db --file=dump.sql # Import database
ddev export-db --file=dump.sql # Export database
ddev xdebug on                 # Enable Xdebug
ddev craft db/backup           # Craft database backup

Post-Install Auto-Run

Composer scripts auto-run craft up after install/update:

{
    "scripts": {
        "post-craft-update": [
            "@php craft install/check && php craft up --interactive=0 || exit 0"
        ],
        "post-update-cmd": "@post-craft-update",
        "post-install-cmd": "@post-craft-update"
    }
}

No need to manually run ddev craft migrate/all or ddev craft project-config/apply — ddev craft up does both, and it auto-runs after ddev composer install/update.

Add-ons

ddev add-on get ddev/ddev-redis       # Install Redis
ddev add-on get ddev/ddev-mailpit     # Install Mailpit
ddev add-on list                       # List installed add-ons
ddev add-on remove ddev/ddev-redis    # Remove add-on

Custom Commands

Place scripts in .ddev/commands/web/ (container) or .ddev/commands/host/ (host):

#!/usr/bin/env bash
## Description: Run ECS code style check
## Usage: check-cs
## Example: ddev check-cs

cd /var/www/html && composer check-cs

Note: omit #ddev-generated on custom commands you maintain — DDEV overwrites files with that comment during updates. Only add-on-managed commands should include it.

Troubleshooting

ddev poweroff                  # Stop all DDEV projects
ddev debug router              # Debug router configuration
ddev debug capabilities        # Check Docker capabilities
ddev delete --omit-snapshot    # Remove project without snapshot
