Creating a new project with BLT

Do not clone BLT or BLT Project as a means of using them. Just follow the directions below.

  1. Pick a machine name for your new project, e.g., my-project. For compatibility with third-party tools, it's best to only use letters, numbers, and hyphens.

  2. Run the following command to create your new project and download all dependencies (including BLT).

     composer create-project --no-interaction acquia/blt-project my-project

    All subsequent steps assume you are in the project directory (cd my-project).

  3. If this is your first time using BLT on this machine, restart your shell so that Bash detects the new BLT alias.

  4. Customize blt/blt.yml if desired, such as to choose an install profile.

    By default, BLT will install sites using the lightning profile. You can change this to any other core, contributed, or custom profile in your codebase. Make sure to download the profile if necessary, e.g., composer require acquia/headless_lightning:~1.1.0.

    To use a profile other than Lightning, enter the name of the profile in blt/blt.yml in the profile:name setting. For example: profile: name: minimal

  5. Now it’s time to spin up your LAMP stack.

    1. Recommended: Run the following command to create a DrupalVM instance:

        blt vm

      To customize your VM (such as to enable Solr or change the PHP version), respond no when BLT offers to boot your VM, and make any necessary modifications to box/config.yml before starting your VM.

    2. Alternative: To set up your own LAMP stack, please review Local Development, then execute the following command to generate default local settings files:

        blt blt:init:settings

      Modify the generated docroot/sites/default/settings/local.settings.php file by adding your custom MySql credentials.

  6. Install Drupal and automatically generate any remaining required files (e.g., settings.php, hash salt, etc...):

     blt setup

  7. Log in to Drupal: drush @my-project.local uli (replace my-project with the name of your project, which should be the value of project.machine_name in blt/blt.yml).

  8. Congratulations, you now have a running local Drupal site using BLT! See Next steps.

Troubleshooting

If you have trouble creating the project, try clearing the Composer cache or increasing the process timeout:

    composer clear-cache
    export COMPOSER_PROCESS_TIMEOUT=2000

If you have trouble using the blt alias, make sure it’s installed correctly and then restart your terminal session:

    ./vendor/bin/blt blt:init:shell-alias -y
    source ~/.bash_profile

If you get syntax errors from vendor packages, check that the version of PHP on your host matches the version of PHP in your VM, or else make sure to always run composer commands from within the VM.

Finally, if you continue to have trouble, review the remaining BLT documentation, search for relevant issues, or create a new issue.
