    2. If you don’t know how to fasten Composer packages to Drupal sideways , then after reading the Drupal publication , Symfony And Friends there should be less questions.

    Everything for a Drupal Developer

    1. Drupal Groups sometimes becomes literally a storehouse of interesting thought-provoking information. In this regard, the discussion in the topic DOM hacks for speeding up page download times , devoted to frontend optimization, became extremely interesting .
    2. Publishing Memory profiling in hooks is a great start for anyone who wants to understand why this particular Drupal site eats so much memory or slows down.
    3. Imagine that you need to select all the nodes through the code for which no Taxonomy term is selected as a category. By default , relying solely on EntityFieldQuery cannot be done. The article EntityFieldQuery, LEFT JOINs and IS NULL conditions represented a stunning overview of tricks that will help you achieve the goal.
    4. A fairly concise solution for switching display views, for example, from a grid to a list, is proposed in the article Simple Views display switch .
    5. It is entirely possible to agree with the authors of article 20 of the Usability Tips For E-Commerce Websites about the fact that a very large percentage of sites on Drupal today are electronic commerce, and their number is constantly growing. This article discusses the issues of increasing the usability of such sites; which almost automatically leads to an increase in their conversion .
    6. If you use Nginx to render statics or reverse-proxies, or just think about performance optimization issues when submitting the same pictures, you might be interested in the article G-WAN as a static Drupal file server , which presents a comparison of different approaches.

    9. If you use some kind of profile or distribution to work on your sites, then it is likely that it comes with some features that may constitute an arbitrary exported configuration, for example, content types. Sometimes there is a need to “clarify” basic features, for example, to remove or add a new field from (to) some type of content, and, like, rewriting plug-ins and features-with-profiles-and-distributions is not the most encouraged Drupal practice (Drupal way). There are several approaches to solving the problem. For example, you may find the Features Override module useful., which allows you to modify (alter) an arbitrary basic configuration. (author: there is not the most pleasant experience of using this approach - through features override, especially when the basic feature can be actively updated by developers, however, it may be useful for your project module). A wonderful article on How To Override Features has recently appeared on this topic , where the author compares many approaches.
    10. Some interesting uses for Varnish are presented in the Varnish Tips and Tricks article .
    11. Quite often, the topic of careful study of roles and access rights is not worked out as carefully as we would like. Try to introduce some system in this topic in the video Preventing Drupal Headaches: Permissions and Roles Checklist .

    2. In the Backdrop Does a Disservice to Developers article, the author continues a long-standing holivar on whether Backdrop CMS benefits or not. As a main argument, there is a risk that “lazy to retrain” developers have an additional incentive to never switch to 8 at all; on the other hand, it is noted that in the labor market, working with Drupal 8 (Symfony) may be more in demand. .
    3. The Responding to Events in Drupal 8 article discusses how to properly respond to events in Drupal 8 using the Symfony Event Dispatcher .

    Business and Community

    1. It is no secret that many organizations and studios involved in developing websites on Drupal quite often conduct audits of solutions of other developers (read, competitors). One of these studios recently published a prospectus on this subject. There is also interesting material on the website of this studio. How do you rate Maintainability? dedicated to such an important attribute of software quality as “serviceability”.
    2. Soon (March 9th), voting will begin on the post of director of communication with the Drupal Association community. Candidates have offered more than twenty candidates .

    Interesting modules

    1. The Asynchronous Prefetch Database Query Cache module , using MySQL native driver for PHP , optimizes Drupal's work with the MySQL database, in particular, prefetching caches, fixes a problem with deadlocks in cache tables, changes the engine to MEMORY for the semaphore table, and much more .
    2. Another attempt to implement a complete site preview system is waiting for us in the Preview Sync module . The authors approached the solution to the problem in a very original way: Preview Sync simply clones the current database into a remote environment, and there it performs all the necessary operations for previews, for example, switching the status of Workbench Moderation , and all this with Drush.
    3. One of the normal practices in auditing a site on Drupal is to check if someone has managed to get into the source code or the kernel of the system and make their own changes there. Hacked module ! allows you to automate this process. (QA: ).

Almost all Drupal developers sooner or later have to crop a large image when pasting, for example, when we are interested in some 200 by 200 pixel rectangle somewhere near the center of the 2000 by 2000 photo. The problem is that the standard Drupal tools (image styles) do not allow you to specify your preferred area. The Focal Point module helps with solving this problem. There is also a wonderful article on working with the module .
