Development of a simple CosmoApps web application from scratch using no-code technology

CosmoApps is a next-generation web and mobile application development system that allows using only a web browser to develop serverless cloud applications deployed in the Microsoft Azure cloud.

Unlike systems such as 1C Bitrix, the emphasis is on automating the process of developing the application interface and excluding, where possible, writing program code. An application is a set of descriptions of objects (documents) of the application and the application as a whole (menu structure, security system, etc.). Thus, to develop an application, you do not need to be a specialist in PHP or ASP .NET – basic knowledge of JavaScript is enough to develop the structure and interface of the application.

When developing an application, you do not need to operate not only with HTML tags, but even with individual web components – the CosmoApps system takes care of all the work here, while the developer concentrates on non-standard tasks.

Application data is stored in the Cosmos DB document database. The use of a documentary database provides the ability to store objects (documents) of an arbitrary structure – any correct JSON can be saved as a document and automatically indexed by all its properties (fields). Each application is allocated a separate section in the collection of documents, which allows you to work with data from a huge number of applications independently and without delay, while making optimal use of resources.

In the above example, it can be seen that data from other types of documents can be included (in whole or in part) within a document...
