What is Drupal?
Drupal is the most popular CMS that can be used for small or large scale websites and applications. It is an efficient and powerful framework to handle large amounts of data, gives the flexibility to add functionality, scalable, secure, extensible, and SEO friendly.
Advantages of Drupal:
It is the most technically advanced CMS and has powerful tools that require experience and expertise to operate.
The platform can be integrated with wide plugins, themes, and configuration tools. It gives the option to edit the root file and code directly. The Drupal developers can easily make significant changes and customize the platform according to the business requirements.
Drupal software can be downloaded freely on Drupal.org and installed on the hosting server.
Drupal gives the ability to tag, organize, and categorize the complex content on the website or web applications.
What is AngularJS?
- A concise and lightweight framework that can make your website fascinating
- Web designers and developers love HTML as it is simple, clear, and intuitionism in the code structure. AngularJS extends the HTML to define the UI and lets you build interactive web apps that have high functionalities.
- Create reusable components using AngularJS
- The client-side ensures that it isn’t affected by cyber attacks
- It has a faster development process, asynchronous technique, multiple views, and SEO friendly development.
- AngularJS has a unit testing setup that makes it fast and easy for developers to test their codes
- It has two-way data binding that immediately triggers application objects and provides an interactive framework.
Benefits of AngularJS:
Maximize the performance
Adding AngularJS to Drupal which has a heavy server-side PHP framework adds some business logic on the client-side. This will improve coding performance as it needs less code for certain things.
AngularJS uses declarative programming that can give a quick sense of static, dynamic, variable names, and code execution.
AngularJS and Drupal
They are the perfect combination to make an impressive frontend and powerful backend content management framework. Drupal is a flexible and scalable CMS that is used to develop web applications for small and large scale businesses. The open-source CMS which is highly customizable and manages business requirements.
The developers usually faced difficulties in building applications, device and browser inconsistency, and program similarity. Let us see what the combination can do together:
Drupal Angular 6
Drupal can give a seamless experience even with heaps of functionality. Sometimes when you offload some business logic to the client-side in AngularJS you are unburdening the Drupal’s backend. AngularJS is used for themes, presentations, and Drupal for the backend data source which can boost the performance of the website or web applications. It allows you to move the display logic into the client-side and streamline the backend which results in increasing the speed of your website.
AngularJS follows the MVC framework that separates the model logic, controller, and business in web applications. The isolation of application logic from the UI gives clear results and a non-redundant coding structure. This helps in removing a lot of backend logic from Drupal thus making it efficient and light-weight.
Drupal assures to provide website security and follow the security protocols diligently. Being a part of a large community there is very little chance of having a security flaw that is not noticed or patched afterward. Headless Drupal and AngularJS together add the extra layer of security into the website. The browser generally communicates with the Angular that means there is no direct interaction with the server-side. This makes it difficult for online attackers to inject any malicious code into the database.
We have discussed the benefits of combining AngularJS and Drupal together. The Drupal Development Company can easily take advantage of AngularJS features and functionalities. You can hire developers that can add interactive elements, dynamic widgets, real-time updates, and many such features. Get in touch with us to know more benefits of this combination.
If you've ever wanted to use Angular for part of a Drupal project, you probably know that a quick google search is going to return all kinds of results about using Angular as a frontend for a detached, headless Drupal backend. But that's not always what you want. You might have an existing site that could be improved by a small scale Angular based component. Or maybe you're wary of the SEO issues that could arise from having an SPA.
Thankfully, this isn't a total no-man's-land. There's an excellent blog post on how to use Angular to provide a drupal component over at Sitepoint. But it's for the first version of Angular, which is unsurprising since it was was written in 2014. It's also trying to do two things at once - showing how to use Angular and providing a marginally useful output.
I'm going to show how to set up an Angular 2 boilerplate module. It doesn't do anything fancy, of course - what your project actually calls for is up to you. But this will get you over that first hurdle and let you start working.
The Drupal Module
Start by creating an empty module. This should be familiar territory. Again, this is going to be extremely bare-bones for now - just a menu item and an empty callback.
In order to keep this compact and reusable, we're going to use a theme function to define the template for this. Implement hook_theme in angular_demo.module so we can provide a template within the module.
Now, let's create a directory called theme inside our module, and inside of it create our template. We'll just use some basic HTML so we can smoke-test it.
This is almost enough to let us confirm that our module is working. Let's populate the page callback.
Enable your module and point your browser at /angular2 on your development environment. You should see the word Test displayed as an h1, inside your site's existing page structure, fully themed.
Adding Angular 2
We do need something for Angular 2 to do, and in that regard the Angular 2 Quickstart provides us the code we need for a Hello World. Note that I've linked to the JS quickstart - compiling JS from Typescript is outside the scope of this tutorial.
We'll start by actually getting the Angular code files. You could put them inside this module, but I'm going to put them in the libraries directory with the assumption that I might need to create another component later.
The quickstart gives us a package.json file. I'm going to put this in sites/all/libraries so that when I run npm-install, I'll have a node_modules directory in that location.
Now, I'm all but certain we don't need lite-server, and possibly concurrently, but I'm leaving them in to keep parity with the quickstart. Once you've created this file, go do sites/all/libraries on the command line and run npm-install. When it's done you should see a tree of installed components.
Angular Drupal Auth
Now we need to add the JS files to our render element, using #attached.
Create the JS files from the quickstart. I'm just going to put these in the module root for now - best practices for naming and location of these files is up to you.
Angular Dual List
And now we add these files to our #attached array.angular_demo.module (modification)
From here, the last step is to change our template file. If you look at the index.html in the quickstart guide, you'll see the expected markup is a single tag inside the body.
Reload your page, and you should see an H1 that says 'My First Angular App'. If it just says 'Loading...' then you've gone wrong somewhere - double check that all your JS files are being included.
If you're still having trouble, or just want to save yourself the copy/pasting efforts, you can find a working sample at the Alloy Github. Don't forget to copy package.json.dist to sites/all/libraries/package.json and run npm-install. It doesn't matter if you do it before or after enabling the module, but it does have to be done for it to work.
