Local Development

Before You Begin​

The example local environment configurations outlined below are based on Lando. To install Lando, follow the Lando installation instructions.

Depending on your role, you may only need a local backend environment, or you may instead prefer a local environment that can run both the backend and frontend. The following sections outline the steps to set up a local environment for each of these use cases.

Backend Only Setup​

If you are creating a local environment for your Drupal backend only, you can use the default Pantheon recipe provided by Lando. For more information, see the Getting Started section of the Lando Pantheon Plugin documentation.

Combined Frontend and Backend Setup​

  • Create .lando.yml in the root of the project.
  • Copy the following config into .lando.yml
name: %SITE_NAME%
recipe: pantheon
config:
  framework: drupal9
  site: %SITE_NAME%
  id: %PANTHEON_SITE_ID%

proxy:
  frontend:
    - %SITE_NAME%-fe.lndo.site:%PORT-NUMBER%

excludes:
  - frontend/node_modules
  - node_modules

services:
  frontend:
    type: node:16
    globals:
      npm: latest
    build:
      - "npm install --prefix ./frontend"
    port: %PORT-NUMBER%
    ssl: true
    scanner: false

tooling:
  node:
    service: frontend
  npm:
    service: frontend
    cmd:
      - "npm --prefix ./frontend"
  yarn:
    service: frontend
    cmd:
      - "yarn --cwd=/app/frontend"

Note: Replace %SITE-NAME%, %PANTHEON_SITE_ID%, and %PORT-NUMBER%, with site name, site id and required port number for the frontend site.

  • Clone the frontend code base into the ./frontend directory. You will most likely want to add this directory to your .gitignore file for the project.
    cd frontend
    git clone [email protected]:pantheon-systems/example-fe-site.git .
  • Consult .env.example to create the required environment variables files for your frontend site.
  • Run lando start to start the containers.
  • Install the Drupal site and select profiles like: pantheon_decoupled_umami_demo & pantheon_decoupled_profile.
  • To start your frontend site, run lando npm run develop. It will now be available at the URL specified in the proxy section of the .lando.yml file.
