Application Development

When is it necessary to develop your own solution?

Now there are many ready-made template solutions that allow you to get a business tool for relatively little money and in a short time. Why then develop individual solutions?

Consider the cases when it is appropriate to resort to custom software development:

Your business has a rather complex and unique logic: there is simply no ready-made solution in the world that will do what you need, in the way you need. Development of software products is the best solution for your specific tasks.

You have a specific niche or product: in such conditions, it can also be difficult to find a ready-made solution, and individual development will help to take into account all the requirements and tasks.

It is difficult for you to choose a service as a service for your business: it often happens that in some packages you do not have enough functions, while in others there are too many of them, and you will have to overpay. This problem is easily solved by the development of your individual software.

Your business is growing and developing: or striving for it. A custom product will help you anticipate and lay out opportunities for future growth and scale so that you don’t have to buy more and more versions of the product every step of the way.

You need many different integrations: often a business uses a set of different tools that help automate as much as possible. For convenience and speed up processes, these tools are integrated with each other.

What is Angular?

Angular is an open source framework maintained by Google. First developed in 2010 as AngularJS, the framework has been updated nearly every year in architecture, syntax, and performance to work seamlessly with the entire JavaScript ecosystem.

Angular helps you run Single Page Applications, and the model-view-controller (MVC) feature makes developing and testing applications as easy and fast as possible. Angular-based applications scale without problems.

Angular is powered by TypeScript, which means code is easier to read, fewer bugs, and self-documenting.

Benefits of Angular

Detailed documentation. Developers can quickly find technical solutions and solve problems that arise.

Google support. The fact that Angular was developed by Google is an advantage in itself. For many developers, this is a sign of the quality and reliability of the framework.

Rich ecosystem of third-party components. The popularity of Angular has resulted in thousands of additional tools and components that can be used in applications. Thanks to this, get additional functionality and increase productivity.

Component architecture. In version 2, Angular moved from MVC to a component-based architecture. According to it, applications are divided into independent logical and functional components. They can be easily replaced and separated, and reused in other parts of the application. This independence simplifies testing of the web application and ensures that all components work smoothly.

Angular AOT Compiler. It converts TypeScript and HTML to JavaScript during the build process. This means that the code is compiled before the browser loads the web app, so it renders much faster. The AOT compiler is also much safer than the JIT compiler.

Angular Universal. This is a method of generating HTML templates on the server, which in turn has several advantages. First, it helps web crawlers to increase the ranking of the application in search engines. Secondly, it reduces page load time and improves performance on mobile devices. These advantages lead to an increase in the number of users.

CLI infrastructure. It automates the entire development process, making provisioning, configuring, and developing applications as easy as possible. The Angular CLI allows you to create a new Angular project, add features to it, and run unit and end-to-end tests with a few simple commands. This not only improves the quality of the code, but also makes development much easier. Ivy Renderer. Function

Ivy Renderer translates application components and templates into JavaScript code that can be displayed in the browser. The main characteristic of this instrument is the «shaking the tree» technique. During rendering, Ivy removes unused code, reducing the batch size. As a result, web applications load faster.

Who needs Angular apps?

Enterprise web applications. TypeScript has all the features you need to develop large scale projects. TypeScript is equipped with auto-completion, advanced refactoring, and navigation features. Moreover, the architecture of this tool makes it easy to reuse and maintain the code.

Applications with dynamic content. Since the main goal of Angular was to create single page web applications, it has a wide range of tools for developing single page application or SPA. What’s more, it’s ideal for websites where content needs to change dynamically based on user behavior and preferences. Dependency injection ensures that if one component changes, other related components will automatically change.

Progressive Web Apps (PWAs). Google developed PWA in 2015. These include applications where certain technologies provide reliability, speed, and attractiveness. Angular makes it easy for developers to turn native web applications into progressive ones.

Therefore, it is possible to single out those projects that do not need Angular. These include: lightweight sites with static content, SEO-optimized sites, short-term projects, and applications built using microservices architecture.

Angular Application Interface Example

Extensive libraries of user interface elements have been developed for the Angular framework: from icons and buttons to menus and sections.

An example of a vertical menu and sections:

An example of a record card, data fields, and a details tab:

An example of analytics, charts and dashboards:

Warehouse example:

Section Chats

All correspondence with clients is stored in the «Chats» section.

The iChat app allocates new chats to the least loaded operators who are in the Ready status. The chats assigned to the operator are reflected in his right communication panel. Mini cards in the right panel are sorted by the time of the last messages, the red indicator shows the number of unread messages.

Sanatel iChat

The Sanatel iChat solution is created and maintained by a Kazakh team of developers using a modern and reliable technology stack: Kubernetes, Node.js, C#. The solution is registered with RSE NIIS as an intellectual property object.

The Sanatel iChat application provides the ability to chat with users in various instant messengers and social networks, in a single operator interface, with chat history saved in the client card. The application also allows you to organize a chat bot based on rules (Rule based). The business process (the script of the chatbot) is built in the regular business process designer of the Creatio platform. Sanatel iChat’s own process designer can be used to build a process.

Support for all messengers

The application supports integration with all common instant messengers and social networks, including WhatsApp (via Infobip).

Including supported widget for the site.
