Onboarding with Acquia BLT¶

This document is intended for developers who have joined a project that already has Acquia 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 Acquia BLT to a project or create a new Acquia BLT-based project, do not use this document. Instead, refer to Installing Acquia BLT.

Before you start¶

If you have been directed to this documentation by a project that’s using Acquia BLT to accelerate its development, testing, and deployment, we recommend exploring all of the Acquia BLT documentation first. Here’s what’s most important to do and know before getting started:

Acquia BLT is distributed as a Composer package. This means that the project you are working on requires Acquia BLT as a dependency in its composer.json file. This also means that you don’t need to install or configure Acquia 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.
You will need some project-specific information to set up your local environment, specifically whether you are using a virtual development environment (for example, DrupalVM), and the name of your mainline development branch (develop or master). This should be referenced in your project’s README file.
If you need help, talk to your project team first, since they may have already encountered any issue you are experiencing. Then post an issue in the Acquia BLT issue queue. The issue queue isn’t only for bugs—we welcome feedback on all aspects of the developer experience.
Verify that your local system and network meet the Acquia BLT system requirements. Also ensure that you have dependencies installed for any virtual development environment (such as VirtualBox and Vagrant for DrupalVM).
Since Acquia BLT makes use of a variety of best practice development tools and processes (including Composer and Git), you should verify that you have the necessary skillset to develop with Acquia BLT.

Initial set up¶

Fork the primary GitHub repository for the project you are developing.
Clone your fork to your local computer. By convention, Acquia 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 master and develop branches, checkout the develop branch:
```
git checkout develop
```
With Composer already installed, run the following command:
```
composer install
```
Install blt alias:
```
./vendor/bin/blt blt:init:shell-alias
```
At this point, restart your shell for the alias work.

If your project uses a virtual development environment (such as Drupal VM), complete the following steps:

Start the VM:
```
vagrant up
```
SSH into the VM:
```
vagrant ssh
```
Build and install the Drupal installation:
```
blt setup
```

If your project does not use a virtual development environment, complete the following steps:

Set up your local LAMP stack with the web root pointing at your project’s docroot directory.
Run the following command:
```
blt blt:init:settings
```
This will generate docroot/sites/default/settings/local.settings.php and docroot/sites/default/local.drush.yml. Update these with your local database credentials and your local website URL.
Run the following command:
```
blt setup
```
This command will both build all project dependencies and install Drupal.

For more information about setting up a local *AMP stack or virtual development environment, see Local development with Acquia BLT.

Ongoing development¶

As development progresses, you can use the following commands to keep your local environment up to date:

Run blt setup to rebuild the codebase and reinstall your Drupal website (most commonly used early in development).
Run blt drupal:sync to rebuild the codebase, import a fresh 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 drupal:update runs database updates and imports configuration changes. For a full list of available project tasks, run blt. For more information, see Project tasks.

Local Git configuration¶

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.

Updating your local environment¶

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 Acquia BLT.

Local development tasks

GitHub configuration¶

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.

Next steps¶
