Exploring the possibilities of the node.js platform in the development of proxy servers, taking into account modern requirements for performance and stability

Abstract

Proxy servers play a key role in modern information systems, providing efficient, secure and scalable operation of networks. Their use allows you to optimize traffic, increase productivity, ensure confidentiality and stability in various environments from corporate networks to personal users. In the field of proxy server development, asynchronous platforms have gained significant popularity and importance. They can significantly increase productivity, improve scalability and ensure smooth servicing of a large number of simultaneous connections. The paper examines the capabilities of the Node.js platform for developing a proxy server using an asynchronous approach and the implementation of independent subservices, in particular, the process of creating your own proxy server implementation is described, including architectural solutions and the modules used. Performance testing was conducted in the FOGLDN Proxy Tester program for the proposed solution, the results of which were compared with the indicators of other popular implementations of Squid Proxy and Tinyproxy. Based on the obtained data, an analysis of the proposed proxy server efficiency was performed, which emphasized the prospects of using Node.js to create proxy servers in scenarios where the balance between performance and ease of implementation is important. The JavaScript programming language, Node.js platform, SQLite database, ORM Sequelize, PM2 process manager, and React library were used to implement the software package.
