I was recently asked to compare the django ecosystem with the drupal ecosystem. Drupal is widely known as a huge open source CMS success with a massive community behind. 

However looking at Google Trend to my biggest surprise I realized that this is not true in 2019 anymore. The django ecosystem is bigger and on top of that, growing in a sustainable way.

Django (red) vs Drupal (blue) – Since 2016 django has surpassed Drupal. Shockingly, the decline in the interest in the Drupal CMS ecosystem is sharp.

It is my experience that most CMS come and go across the years. The django ecosystem appears to be much more robust than any CMS ecosystem because it doesnt just cover CMS functionality, as a web application framework it covers a much broader scope, with the django CMS package covering the CMS part.

As you can see here, Django is amongst the top three open source web technology ecosystems and it is on a continuous growth path:

django CMS itself is much leaner than other CMS, as it sits on the shoulder of a giant: django – this makes it more long-living and much more maintainable than other CMS projects.

I hope I could give you some insights into the advantages of django + django CMS. Please let me know if you have any questions.

For more information about the technology stack, I’d also point you to the slightly technical articles I wrote about django and django cms.

Disclaimer: At what.digital django and django CMS is our main backend technology stack.

Would you like to contribute to this article? Please let me know. For example, do you think Google Trends is a good way to look at how future-proof a technology is?

Divio is the company that originally founded django CMS a couple of years ago and that still contributes to developing it further together with the rest of the django CMS community.

Divio is a professional, modern cloud hosting company specialized in hosting python / django / django CMS projects in a highly secure, performant and efficient way.

Divio relies on data centers in Europa and North America via Amazon Web Services (AWS) and in Switzerland – its hosting is fully scalable, meaning that we could host websites with Divio that would be used by hundreds of thousands of daily users.

Amongst Divio’s customers are small to large enterprises in Switzerland and across the globe including S&P Fortune 500 companies and global financial institutions.

Divio is headquartered in Zurich, close to Hardbrücke and has offices in New York City and Stockholm as well as a technical team distributed around the world to be able to respond to support requests around the clock (24/7).

At what.digital what we like about divio.com hosting is:

• simplicity of the divio.com control panel to launch and maintain projects for our clients
• very competitive pricing
• simple backup
• quick responses from their support staff
• robust developer tools for django and django CMS projects

Django is a modern web application (backend) framework with lots of support to scaffold web applications.

Django was designed to help developers take applications from concept to completion as quickly as possible.

https://www.djangoproject.com/

The main advantages are:

• Secure: Django has built-in state-of-the-art security.
• Efficient: Django has some of the best scaffolding tools to build web applications fast and efficiently (ORM including fully automated database migrations, admin interface, form generation, user authentication, management and permissions, REST API support, and much more). This means that applications can be developed quicker and more cost-efficiently, and the maintenance cost is lower in comparison with other web frameworks.
• Popular: Django is very popular and has a huge community. Looking at Google Trends, Django emerges as a top-three web framework next to Spring and Laravel. Being so popular, Django has tons of well-maintained modules. These modules are well organized – check it out at https://djangopackages.org/.

By the way: Django also has very good Content Management (CMS) support via projects like Django CMS or wagtail.

Introduction

Why Django CMS? Django CMS is a good choice for companies that depend on their website to drive business and generate user value.

For Editors and Marketing Managers: Django CMS empowers editors to select from custom-made page templates and content elements without any dependency on developers. Watch the video below:

django CMS is user friendly and has a very intuitive drag and drop interface.
It’s built around the needs of multi-lingual publishing by default, not as an afterthought: all websites, pages and content can exist in multiple language versions

https://www.django-cms.org/en/

Full list of django CMS features:

• Frontend Editing
• Modular Content Management. Editors can choose from…
  • content elements (plugins)
  • templates for a whole page
  • templates for just parts of a page (sections)
• Full Multi-Language Support
• Simple publishing process (draft / published)
• Multi-Site Support (manage different sites with different domains in the same project)
• Support for all aspects of SEO and Social Media cards / integrations
• Full-fledged admin interface and site settings
• different levels of permissions for editors
• Full-text search
• Undo / Redo / Revert to published version for editors
• … and more

For Developers: Developers can use the full power of Django, a top-three open-source web framework which is also at the core of Django CMS, to build state-of-the-art applications (such as an online course booking tool) that integrate smoothly with the rest of the website. Moreover, developers can include CMS functionality in their applications, creating a perfect blend between application logic and manageable content.

Demo

Here you can create your own demo web server with Django CMS and a demo theme installed out of the box. No setup required.

The demo theme consists of standard components. It allows you to build your own page templates. Components include image sliders, text and images in one or multiple columns, tabbed content and much more.

First Steps: In Django CMS, all content can be edited right on the website itself. Append ?edit to the current URL and hit enter. Now you should see the admin bar where you can log in with the admin username and password that you received (or if already logged in, just hit the ‘Edit’ button). Then try double-clicking on a text anywhere on the page and an editor window will open.

The Structure Mode

The structure mode allows an editor to insert content elements (a.k.a. plugins) and to change their order on the page. Try it out! Here is how to use the DjangoCMS structure mode.

More Admin Tools

There are some additional admin tools that allow you to publish / unpublish pages, manage multi-language, etc: Read more at http://docs.django-cms.org/en/latest/user/reference/page_admin.html

Here is the link to the full documentation for editors: http://docs.django-cms.org/en/latest/user/index.html

The goal: What the app marketer would like to do: Prepare links with Google Analytics utm parameters that lead the user to the app (either via download & install through the app store or directly to the installed app) and then use these links in online marketing campaign across the board (email marketing, social media marketing, search engine marketing, display advertising, etc.)

The Solution (experimental): Firebase Dynamic Links

Here is how you can create such a Firebase Dynamic Link manually and here is the debug view of an example of a Firebase Dynamic Link: https://example.page.link/?link=https://www.our-client.com&d=1&utm_source=google&utm_medium=cpc&utm_campaign=summer-campaign

According to the official documentation, these links will work on both iOS and Android, whether the app is installed or not. Google Analytics utm_parameters appear to be fully supported.

Dynamic Links work across app installs: if a user opens a Dynamic Link on iOS or Android and doesn’t have your app installed, the user can be prompted to install it; then, after installation, your app starts and can access the link.

…

When a user opens one of your Dynamic Links, if your app isn’t yet installed, the user is sent to the Play Store or App Store to install your app (unless you specify otherwise), and your app opens. You can then retrieve the link that was passed to your app and handle the deep link as appropriate for your app.

There are some comparisons out there on the web, but they appear to be shallow. Most of them just cover performance (Django wins), security (Django wins), learning curve (Django wins) and API (django loses, even though there is excellent API support in the form of a well maintained package called Django Rest Framework).

Let’s try to find out the real differences by looking at the different steps needed to build a simple blog application.

Disclaimer: I know Django quite well and Laravel not at all. Which means I am biased. Please collaborate via mario@what.digital to improve the Laravel part of the comparison.

In most cases javascript code should be deferred so it doesnt block the page loading process.

Javascript files can be deferred simply like this, the execution order of deferred scripts will be strictly kept by browsers in the order of appearance in the HTML file:

<script defer="defer" src="vendor.js"></script>
<script defer="defer" src="app.js"></script>

However projects might require inline js code. That code will execute before the deferred scripts – which might throw errors if the inline js code depends on libraries loaded via deferred script tags. Inline js code can be deferred like described on stackoverflow:

<script>
    window.addEventListener('DOMContentLoaded', function() {
        (function($) {
            //
        })(jQuery);
    });
</script>

defer was introduced before async. Its execution starts after parsing is completely finished, but before the DOMContentLoaded event. It guarantees scripts will be executed in the order they appear in the HTML and will not block the parser.

https://hacks.mozilla.org/2017/09/building-the-dom-faster-speculative-parsing-async-defer-and-preload/

Once all of your js is either triggered by DOMContentLoaded or has the `defer tag it is easy to manage and maintain control of the execution order.

This is a proof of concept to get data from a google spreadsheet via frontend only and display it in a vuejs app, deployed via gitlab pages: https://what-digital.gitlab.io/vuejs-gsheet-query-api-search-demo

The purpose is to use Google Spreadsheet as a “cheap” data source for a widget on a website.

The project source is public: https://gitlab.com/what-digital/vuejs-gsheet-query-api-search-demo
