Of course, you need a back-end framework as well. If you wish to have the backend built with PHP, you can hire a PHP application development company.
With each new version, Angular keeps becoming more powerful. However, a major problem with this framework is its complexity. When compared to some other frameworks like React JS and especially Vue JS, Angular may not be the wisest choice for programmers who want to keep things simple and easy. However, PHP can be used with each of these frameworks. Laravel (Blade) ships with Vue. No matter the framework you intend to use, you can go for a custom PHP development company.
Angular 6 provides a lot of packages for building enterprise-level web applications. It is possible to write codes to build real-time web applications with Angular 6 but this largely depends on what is considered a real-time application.
While Angular may play a role in building a functional real-time web application, you need some other tools to do that. For instance, if you are building a real-time chart, you might have to make use of Angular in conjunction with Socket.IO and maybe D3. Of course, you can also use some other tools to achieve this purpose but Angular alone may be somewhat limited.
What is considered a real-time web application is mostly an application that updates sections in real-time. Of course, Angular 6 has features to achieve this and even more. However, the framework’s component-based architectural design places some limitations in its efficiency for real-time applications. For instance, Angular is designed such that components wrap other components. While this is fine and efficient for most applications and usage, it may slow things down a bit in real-time applications.
This is why more direct processes are better for building real-time applications. Graphing packages like D3.JS, amCharts, Flot, Google Charts, and Highcharts are more suitable than Angular 6 for building real-time web applications. However, if you don’t mind the minor lag in performance, Angular 6 can be used for such applications.
Real-time web application development wouldn’t be complete without the backend. If you wish to build a robust real-time application, hire a PHP development services company.
