Visit the [project website](https://contao.org) for more information. Purpose ------- [](#purpose) The purpose of this package is to develop the Contao bundles in a monorepo. Use it when you want to create a pull request or report an issue. The monorepo is automatically split into separate packages: - [CalendarBundle](https://github.com/contao/calendar-bundle) - [CommentsBundle](https://github.com/contao/comments-bundle) - [CoreBundle](https://github.com/contao/core-bundle) - [FaqBundle](https://github.com/contao/faq-bundle) - [ListingBundle](https://github.com/contao/listing-bundle) - [MakerBundle](https://github.com/contao/maker-bundle) - [ManagerBundle](https://github.com/contao/manager-bundle) - [NewsBundle](https://github.com/contao/news-bundle) - [NewsletterBundle](https://github.com/contao/newsletter-bundle) **Please do not use `contao/contao` in production**! Use the split packages instead. Platinum partners ----------------- [](#platinum-partners) Thanks to our platinum partners for helping us fund the development of Contao.

Start by installing it in your current directory: ``` composer create-project --no-install contao/managed-edition ``` Replace `` with the directory where you want to install the Managed Edition (use `.` for the current directory). Replace `` with `dev-main` if you want to add a new feature, or with `.x-dev` (currently `5.3.x-dev`) if you want to fix a bug. Then adjust the `require` section in your `composer.json` file, so Composer loads the monorepo instead of the individual bundles: ``` "require": { "php": "^8.4", "contao/contao": "dev-main" }, ``` Again, use `dev-main` if you want to add a new feature or `.x-dev` if you want to fix a bug. Next, install the dependencies: ``` composer update ``` Composer automatically clones the Git repository into the `vendor/contao/contao` folder. You can complete the setup by running `vendor/bin/contao-setup` on the command line. Any changes you make in `vendor/contao/contao` will be tracked via Git, so you can submit your pull request directly from your application. Running scripts --------------- [](#running-scripts) First install the code quality tools in `vendor/contao/contao`: ``` composer update composer bin all install ``` Then run the code quality scripts via Composer: ``` composer all ``` You can also run the scripts separately: ``` composer rector composer ecs composer service-linter composer monorepo-tools composer unit-tests composer functional-tests composer phpstan composer depcheck ``` Use the `--` argument to pass additional flags to the underlying commands: ``` composer unit-tests -- --filter CoreBundle composer ecs -- --clear-cache ``` Functional tests ---------------- [](#functional-tests) To set up the functional tests, create a database named `contao_test`: ``` mysql -e "CREATE DATABASE contao_test" ``` If your database uses credentials, copy the file `core-bundle/phpunit.xml.dist` to `core-bundle/phpunit.xml` and adjust the following line: ``` ``` Then run the functional tests via Composer: ``` composer functional-tests ``` Node.js ------- [](#nodejs) To build the assets, you need a Node.js version >= 18.12. Then run these commands: ``` npm ci npm run build ``` End-to-end tests ---------------- [](#end-to-end-tests) The Contao end-to-end tests are availabe as an [NPM package](https://www.npmjs.com/package/contao-e2e-tests). You can install and run them like this: ``` npm install contao-e2e-tests --save-dev npx contao-e2e-tests ``` License ------- [](#license) Contao is licensed under the terms of the LGPLv3.
