Drupal 8

Migrate API is awesome, and if you plan some custom migration, a few contributed modules does the heavy lifting for you. This article should be regarded as a list of steps to follow to achieve a simple migration from another SQL data source than Drupal. So we will not go in deep into the explanations of the Migrate theory, for this subject, refer to the documentation of the Migrate API. Also, we will finish with some debugging techniques and a first shot of a bash script for rerolling a migration from scratch in case of configuration change.

The first post of this serie focused on setting up easily a multilingual Drupal and React environment for a museum Audioguide web app. This one describes the steps to achieve a MVP that displays a list and a detail page of Audio contents, so we have the opportunity to cover several basic concepts under React : Components (add from a package repository, inherit, compose, create), Routes (default route and wildcard), Fetch to consume Rest, Localization via React Intl

The goal of this serie of posts is to achieve quickly a simple museum Audioguide web app based on a React isomorphic boilerplate with a Drupal 8 backend that uses the latest standards. The web app will be fully decoupled by being hosted on another domain than the Drupal one. As a real world case, we want it to be fully multilingual. This is the first post of a serie of 3. This first one focuses on having a Drupal and React setup that meets our requirements. The second one will define a MVP that will just fetch the audioguides list and a detail view (GET operation), the last one will then add extra features like getting user feedback (POST operation).

The scope of this article is to illustrate the responsibilities of several tools and techniques used in the Drupal ecosystem (Composer, Drupal Console, Drush, Configuration management) to achieve quickly a simple custom Google Maps use case: an Address field will be defined on a content type. We want the address to be geocoded automatically for each node on save to display a Google Map. The display of the map will be achieved by a custom module to allow further extension.

Things have evolved quickly, we have now a huge bunch of helpers since 8.2.x in core for Drupal to Drupal migration: Migrate, Migrate Drupal and Migrate Drupal UI.

This setup is intended for production use on a dedicated server (VPS, ...). For development purpose it should be preferable to use Drupal VM, it comes with a default Solr configuration that can be enabled via the config.yml file. If you are using Drupal VM and want to configure Search API for Solr, you can jump to point 4.

Some modules, like Address or Search API Solr, really needs an installation with Composer. We should now avoid to rely on Composer Manager (deprecated) so here is a kickstart.
