About WordPress and Angular

WordPress is undoubtedly one of the most sought-after Content Management System or CMS. The work of a CMS is quite simple as it helps the different businesses manage all their content. And we all know that WordPress has been quite remarkable with that. As of late, there has been quite a trend of the decoupling of the front-end and back-end of a website via headless CMS. This is essentially a good practice for companies looking into the integration of a better UX in the web applications they have. A headless CMS has benefits such as helping keep the database and the representation entirely separate from each other. Once that is achieved, multiple front-end technologies can be used like Angular for a more splendid user interface.

The Angular app is a remarkable JavaScript framework that offers functionality out of the box with maximum productivity and maintenance and a wide selection of choices. WordPress CMS is another mind-blowing software when it comes to creating blogs. What about combining these two? Of course, you can create a new angular app by connecting it to a WordPress site, and this fantastic combination will give you a single-page website or CMS-powered angular website in a short period. It will provide you with a manageable content preview, including the title, content, and publishing date. WordPress tools such as content managing systems and plugins create a WordPress Angular combination that you have sought.

Getting started with the integration

Steps on Integrating Angular and WordPress

To begin, you must have Node JS and node package manager on your window system. You can install them easily through windows installers using download links of the latest software versions. After Angular has been established, now is the time to start navigation of the projects folder to create the first project. This is possible by typing the following command for the creation of a folder in the directory you currently reside:

ng new my-app

Enter the created folder and then type the command that will help you get the first skeleton app to run on localhost:4200 through default:

ng serve

Generation of Components and the Apps’ Backbone Building:

We will start with the building of the application via creating specific components through a state-of-the-art Angular tool – Angular CLI with an included official starter kit. It begins with the creation of four components header, footer, category, and single, respectively. The header and footer are self-explanatory, whereas the category and single components will be holding the category and single templates.

The ng generate component will work on creating a folder that will contain the HTML template of the overall composition and a stylesheet. This component will also provide an additional thing for you in the form of inclusion in the app module file and declaring them in a declarations array.

For the integration of Angular into the headless WordPress, there are two ways. The first is by the installation of WordPress directly in the Angular application. The second one is installing WordPress outside of the application and then integration via an Application Programming Interface or API. We will be focusing on the second method here; the headless WordPress website is ready, so now the next business of order is integrating the Angular application via API. For this integration to proceed, you will have to have a REST API plugin installed to extract the JSON data.

Before getting on with the displaying of the posts via the content of a WordPress website, there is a need for the installation of an Angular App. Let us look at how you can implement this to the front-end of your website.

  • Step 1: There is a need to access the app.module.ts and importing the module known as HttpClientModule
  • Step 2: Once the modules have been imported, you require the post variable's declaration and retrieving the data from the destination URL that was created in the static WordPress website.
  • Step 3: Now that the post variable's declaration is made, you have the option of displaying the post on a loop with the ul>li tags. With this, you can now create features such as post videos, images, blogs, and even texts. It has the tenacity of becoming an utterly user-generated content platform having a Headless CMS at its core, fully integrating the WordPress Angular into each other.
Understanding the language interations

PHP and Angular Resources

PHP, the language WordPress is built from, is one of the server languages that could be used to build server-side web apps, whereas; Angular is one of the client-side platforms for building front-end mobile apps and web apps. How could both technologies be connected to the development of the same app, making a useful Angular PHP?

Web applications have both a front-end and a back-end development "environment." PHP can be used in the back end to access the server resources such as a MySQL database and then use Angular in the front end for structuring and the building of the user interface that usually is based on the consumption and the rendering of the data coming from the servers.

Traditionally, the PHP takes care of all the preprocessing of the PHP code and rendering an HTML page, then sending it to the client browser. However, with Angular, that is no longer the case since all the processing done in PHP is now done inside the browser due to Angular. There are two ways the connection of the Angular front end to the PHP back-end:

The first one is the usage of separate PHP and Angular apps. In this way, building and exposing a REST API from the back-end PHP is needed. The PHP is then used for interaction with the database and sending front-end the JSON responses needed to build an Angular front-end app consuming the REST API by sending the HTTP calls to the API endpoints and rendering the received data. This is the best way as it allows for one to build a single back-end that is connected to multiple mobile apps and the web. The second way is the usage of a singular app containing both Angular and PHP. In this way, the PHP app requires an ability to serve the front-end Angular to create PHP and Angular Resources.
