How could I have possibly left out precisely Drupal's powerful CLI that enables you to: Debug Your Drupal 8 Projects with Drupal Console

it displays a toolbar at the bottom of your Drupal site, one presenting you with useful data about your memory usage, number of queries etc.ģ.Note: printing a variable content takes nothing but inserting the following syntax in a Twig template: you get to place the variable into a neatly formatted structure, one hiding/showing their levels of objects/arrays

Next, once you're done with those particular development/changes making tasks, you just need to rebuild your Drupal 8 cache and you're. It's the debug: true parameter that will actually enable Twig's debugging process and trigger the display of the used Twig templates along with their paths. They'll inevitably contain matching suggestion templates pointing out to you precisely those templates (menus, blocks, pages.) that you need to override, as well as their file names.

The ultimate convenience about using this mode is that you get to refine your searches (trying to discover which part of your HTML code has been written in which Twig templates) by the HTML comments surrounding your templates! How? By copying and pasting the following code either in the sites/default/services.yml file or in the one: parameters: Then switch your focus to Twig and run a debugging session on this template, too:ĭrupal 8 comes with an out-of-the-mode theme debugging mode that you just need to. Next, as you might already guess, you'll need to run a a couple of values uncomment/updating sessions, but I'm not going to get into details in this post about the lines that you need to focus on. Just copy (remember to rename it, too!) your sites/ file to sites/default/. Whether it's a Drupal 8 module or a Drupal theme that you're developing, clear the Drupal 8 cache so you can visualize the changes you're making, the whole work in progress in real time!Īnd with the solution comes the great news, too: catching (most of it) can get disabled right from a Drupal setting file. The solution? Turning off caching during development! With every change that we make we risk to be forced to rebuild the site cache, from scratch. The fact that Drupal 8 caches much more stuff than its predecessors (rendered Twig templates and blocks here included!) can inevitable overly complicate things when we're coding, right?

What looks like an enhancement brought to Drupal 8 can easily lead to. To lend you a hand, I've put together a selection for you, grouping the most popular techniques that range from the quick to use “track down and take out” ones, to the “top refined” methods of debugging! Here they are: And so, debugging turns into a matter of simply making up your mind, choosing the method that best suits your Drupal 8 project. Luckily, the “there's a module for any functionality you need in Drupal” stands when it comes to debugging, as well: you're “spoiled” with a plethora of ways to debug your Drupal 8 projects. Admit it: there's no such thing as unbeatable “bug-proofing” web development technique! Bugs will hit your Drupal 8 projects sooner or latter and you need to have the most effective techniques under your belt for tracking and taking them down.
