Setup the TYPO3 installation

git clone

Switch into your empty htdocs directory of choice and clone a fresh master of TYPO3:

git clone git://git.typo3.org/Packages/TYPO3.CMS.git .

Git GUIs

If you rather like to work with your favorite Git GUI, we compiled a list of the ones used throughout the core team here.

composer install

Run composer install in the same directory you cloned the master repository to. This may take several minutes:

# cd <cloned project>
composer install

yarn install

Go to the Build folder of your TYPO3 install root directory. Install all dependencies with yarn install . Wait for the the end of the install progress. Type yarn build for the build process.

cd Build
yarn install
yarn build
cd ..

yarn tasks

The following is a list of available build targets (see package.json for an up-to-date list). You will only be needing these if you want to do something specific. Usually, it should suffice to use yarn install and yarn build .

  • yarn build - Compile everything.
  • yarn build-css - Compile SCSS to CSS.
  • yarn lint - Test your SCSS and ts files.
  • yarn build-js - Compile JavaScript.
  • yarn format - Resolve Style issues.
  • yarn update - Update dependencies (Use this if you are really sure what you’re doing).

Setting up a Working TYPO3 Installation

You will now need to use your git clone to setup a working installation of TYPO3. There are many different ways how you can do this. We will provide a few examples in the Appendix:
