Dependency Updates for Drupal with Composer

Use when:

• Checking which packages are outdated
• Updating Drupal core to a newer minor or patch release
• Updating contrib modules or libraries
• Resolving composer version conflicts after an update

---

Before You Start — Create a Branch

This step is mandatory. Do not run any composer commands until a new branch is created and confirmed. Never update packages directly on main or master.

Check the current branch first:

git branch --show-current

If the user is on main, master, or any protected branch, stop and ask: "What would you like to name the new branch for these updates?"

Suggest a default if they are unsure (e.g., deps/drupal-updates-YYYY-MM-DD).

git checkout -b <branch-name>

Confirm the new branch is active before proceeding:

git branch --show-current

Only continue to the next step once the output confirms a non-protected branch.

---

Check for Outdated Packages

composer outdated

Shows all packages with newer versions available. Columns: current version → latest available.

Check only direct dependencies

composer outdated --direct

Check a specific package

composer outdated drupal/core-recommended

---

Update a Specific Package

composer update drupal/package --with-all-dependencies

Update multiple packages at once

composer update drupal/package1 drupal/package2 --with-all-dependencies

---

Update Drupal Core (Minor or Patch)

Drupal core is split across multiple packages. Update all together:

composer update drupal/core-recommended drupal/core-composer-scaffold drupal/core-project-message --with-all-dependencies

Note: Minor upgrades (e.g., 10.2 → 10.3) may require relaxing the version constraint in composer.json first:

"drupal/core-recommended": "^10.3"

Then run the update command above.

Verify the installed version

composer show drupal/core | grep versions

---

Update All Packages

Update everything within existing composer.json constraints:

composer update

This updates composer.lock but will not change version constraints in composer.json. Packages pinned to an older major will not cross that boundary.

---

Update All Drupal Contrib Modules

composer update "drupal/*" --with-all-dependencies

---

Resolving Conflicts

"Your requirements could not be resolved"

Find what is blocking the update:

# What requires the package you're trying to update?
composer why drupal/package

# What prevents the target version?
composer why-not drupal/package 2.x

Adjust the conflicting constraint in composer.json and retry.

Conflict between two contrib modules

# Check full dependency chain
composer depends drupal/module-a
composer depends drupal/module-b

Update both together to let composer find a compatible set:

composer update drupal/module-a drupal/module-b --with-all-dependencies

Revert a bad update

If composer update introduced a regression, restore the previous lock file from version control and reinstall:

git checkout composer.json composer.lock
composer install

If the update was already committed, revert the commit:

git revert HEAD
composer install

---

Verify the Update

# Confirm installed versions
composer show drupal/core-recommended
composer show --outdated

Run composer audit after any update to confirm no new advisories were introduced:

composer audit

Confirm Drupal still bootstraps

If Drush is available locally:

drush status

Expected: Drupal bootstrap: Successful. If bootstrap fails, do not commit — investigate before proceeding.

After verification, always ask the user these questions in order:

1. "Do you want to commit these changes?"

• If yes:

  git add composer.json composer.lock
  git commit -m "Update Drupal dependencies"
  

• If no → remind the user that composer.json and composer.lock are uncommitted before proceeding.

2. "Do you want to deploy these changes to an Acquia environment?"

• If yes → follow the Drupal Update and Deploy playbook to push code, switch the environment, and optionally trigger a pipeline build.
• If no → done.

3. After deployment: Run database updates on the target environment before marking the work complete:

drush updb --yes
drush cr

Troubleshooting

Problem	Command
Update ignored — package still old	Check constraint in composer.json; relax if needed
composer install fails after update	Run composer why-not package version to find conflict
Unexpected packages changed	Review git diff composer.lock before committing
Memory limit error	COMPOSER_MEMORY_LIMIT=-1 composer update
