description: The purpose of the work is to create a web application to optimize and simplify the control of expiration dates, as well as the formation of a list of products subject to markdown. The subject area is investigated, the existing solutions are considered, the requirements for the finished application are formed. Approaches to the development of web applications are considered, frameworks for the client side are compared, the capabilities of the Node platform are studied.Js and PostgreSQL databases. A client-server web application with authorization and authentication using a JWT token has been developed. The finished application was tested using modular and integration testing. The Jest library was used for this. The developed solution was packaged in a Docker container. The result of the work was a ready-made web application for monitoring the shelf life of the product and its markdown.
