This plugin automates that entire workflow into two commands and a clear three-step process. Installation ------------ [](#installation) ``` composer require b13/typo3-updater ``` You can set it up for all your projects in a global way: ``` composer require global b13/typo3-updater ``` Upgrade workflow ---------------- [](#upgrade-workflow) Upgrading from e.g. TYPO3 12 to 13 is a three-step process: ### Step 1: Prepare extensions for the target TYPO3 version [](#step-1-prepare-extensions-for-the-target-typo3-version) ``` composer typo3:extensions:update ^13.4 --dry-run ``` Updates extensions to versions that are compatible with the **target** TYPO3 version, while still running on the **current** core. This is the safest first step because it doesn't touch the core yet — only extensions are updated. The command shows a compatibility table comparing each extension against both the current and target TYPO3 versions, then interactively offers to bump constraints and run `composer require`. Use `--dry-run` to only see the table without making changes. ### Step 2: Update TYPO3 core (and remaining extensions) [](#step-2-update-typo3-core-and-remaining-extensions) ``` composer typo3:core:update ^13.4 ``` Updates all `typo3/cms-*` constraints to the target version. It also detects any remaining extensions that are still incompatible and finds their latest compatible versions — so everything is resolved in one `composer update -W` call. Use `--dry-run` to preview all changes without modifying anything. ### Step 3: Update extensions to their latest versions [](#step-3-update-extensions-to-their-latest-versions) ``` composer typo3:extensions:update ^13.4 ``` Now that the core is at 13.4, running the same command again finds the **latest available version** of each extension for the running TYPO3 version. This ensures you're not stuck on the minimum compatible version but running the newest release. Use `--dry-run` to audit which extensions have newer versions available. ### Quick reference [](#quick-reference) ``` # Step 1: Prepare extensions for the upgrade composer typo3:extensions:update ^13.4 # Step 2: Upgrade TYPO3 core and remaining extensions composer typo3:core:update ^13.4 # Step 3: Bring all extensions to their latest version composer typo3:extensions:update ^13.4 ``` Commands -------- [](#commands) ### `composer typo3:core:update ` - Update TYPO3 core and extensions [](#composer-typo3coreupdate-version---update-typo3-core-and-extensions) The main command for upgrading the TYPO3 core. It handles core packages and third-party extensions in one go. ``` composer typo3:core:update ^13.4 --dry-run # Preview all changes without modifying anything composer typo3:core:update ^13.4 # Apply changes after confirmation ``` **What it does under the hood:** 1. Reads the root `composer.json` and collects all `typo3/cms-*` packages whose constraints don't yet match the target version 2. Scans all installed extensions (packages of type `typo3-cms-extension`) and checks whether their `typo3/cms-core` constraint is compatible with the target version 3. For each incompatible extension, queries Packagist for the latest compatible version (stable first, falls back to pre-release if no stable version exists) 4. Displays up to three tables: - **Core packages:** `typo3/cms-*` constraint changes (e.g. `^12.4` -> `^13.4`) - **Extensions to upgrade:** extensions that need a version bump, including the new constraint (pre-release versions are flagged) - **Unresolvable extensions:** extensions with no published version compatible with the target (warning) 5. Shows the exact `composer update ... -W` command that will be executed 6. On confirmation: writes all new constraints to `composer.json` (respecting `require` vs `require-dev`) and runs `composer update` with `-W` (update with all dependencies) 7. On failure: reverts `composer.json` to its original state **Without this plugin** you would need to manually: open `composer.json`, change every `typo3/cms-*` constraint, search Packagist or TER for each extension to find a compatible version, update those constraints too, run `composer update`, and if it fails, figure out which package is the problem and revert your changes. --- ### `composer typo3:extensions:update ` - Check and update extension compatibility [](#composer-typo3extensionsupdate-version---check-and-update-extension-compatibility) A versatile command for managing extensions. It serves two purposes depending on the context: - **Before a core upgrade** (target version > installed version): shows which extensions are compatible with the target TYPO3 version and offers to update them - **After a core upgrade** (target version = installed version): finds the latest available version of each extension for the running TYPO3 version and offers to update them ``` composer typo3:extensions:update ^13.4 --dry-run # Show compatibility table only composer typo3:extensions:update ^13.4 # Interactively update extensions ``` **What it does under the hood:** 1. Loads all installed TYPO3 extensions (from `require`, `require-dev`, and path repositories) 2. For each extension, queries Packagist for the latest version compatible with the **currently installed** TYPO3 core 3. When the target version is newer than the installed version (upgrade scenario), additionally: - Queries Packagist for the latest version compatible with the **target** TYPO3 version - Shows a compatibility column comparing current vs target 4. Displays a compatibility table with columns: - Current installed version - Latest compatible version (for the current core) - Compatibility status for the current TYPO3 version - Target TYPO3 compatibility (only in upgrade scenario) 5. With `--dry-run`: stops after the table 6. Without `--dry-run`: asks for confirmation, then interactively offers to: - Bump version constraints in local package `composer.json` files (e.g. path repository extensions) - Run `composer require` (and `composer require --dev` separately for dev dependencies) to update extensions 7. On failure: reverts all modified `composer.json` files to their original state **Without this plugin** you would need to: manually check each extension's page on Packagist or TER, compare version constraints, figure out which version supports your target TYPO3 version, and update constraints in potentially multiple `composer.json` files across your project.
