This document is intended for developers who have joined a project that already has BLT installed. It is a quick-start guide for getting your local development environment set up and getting oriented with the project standards and workflows.
If you are attempting to add BLT to a project or create a new BLT-based project, do not use this document. Instead, refer to Installing BLT.
If you have been directed to this documentation by a project that’s using BLT to accelerate its development, testing, and deployment, we recommend exploring all of the BLT documentation first. Here’s what’s most important to do and know before getting started:
composer.json
file. This also means that you don’t need to install or
configure BLT globally on your computer, or as a separate tool—run
composer install
on the parent project and install a bash alias (as
described below), and you’re ready to go.develop
or main
). This should be referenced
in your project’s README file.Fork the primary GitHub repository for the project you are developing.
Clone your fork to your local computer. By convention, BLT refers
to your fork as origin
and the primary repository as upstream
):
git clone [email protected]:username/project-repo.git
git remote add upstream [email protected]:acquia-pso/project-repo.git
If your project uses separate main
and develop
branches,
checkout the develop
branch:
git checkout develop
With Composer already installed, run the following command:
composer install
Install the BLT Launcher:
./vendor/bin/blt blt:init:shell-alias
At this point, restart your shell for the alias work.
Acquia recommends that you take advantage of one of the many virtual personal development workspaces that are available for development. Acquia recommends that you use Cloud IDE or Lando using the Acquia recipe.
You must run BLT commands inside the virtual environment. For example, if the project is utilizing Lando:
Start the VM:
lando start
Build and install Drupal:
lando blt setup
If your project does not use a personal development environment, or your terminal session is already running inside the container(s), BLT commands can be run without the Lando (or other) prefix.
For more information about setting up a local *AMP stack or virtual development environment, see Local development with BLT.
As development progresses, you can use the following commands to reset your local environment (typically perform a git rebase and/or create a branch):
blt setup
to rebuild the codebase, install a clean Drupal website
from scratch, and run schema and configuration updates (most commonly used
early in development).blt sync
to rebuild the codebase, synchronize a database
from a remote environment, and run schema and configuration updates (most
commonly used later in development).Each of these commands is a wrapper for several more granular commands that
can be run individually if desired. For instance, blt sync
runs
blt drupal:update
which runs the necessary Drush commands to update the
database and import configuration. For a full list of available project tasks,
run blt
. For more information, see Project tasks.
For readability of commit history, set your name and email address properly:
git config user.name "Your Name"
git config user.email [email protected]
Ensure that your local email address correctly matches the email address for your JIRA account.
The project is configured to update the local environment with a local Drush
alias and a remote alias as defined in blt/blt.yml
or
blt/local.blt.yml
. Given that these aliases match those in
drush/sites/
, you can update the website with BLT.
To more easily identify developers in a project, be sure to set a name and profile picture in your GitHub profile.
When working with GitHub, the hub utility can be helpful when managing forks and pull requests. Installing hub can depend on your local environment, so follow the installation instructions accordingly.
