Express.js

Express.js is a backend framework for developing web applications and APIs. It builds on the Node.js platform and is one of the most popular technologies in this ecosystem.

Low cost and easy extensibility make Express.js a practical solution for projects in the early stages of development. Its main advantages include simplicity, flexibility, and rapid deployment. This makes it often used in minimum viable product (MVP) development, where the goal is to bring an application to market as quickly as possible and then modify it based on user feedback.

When combined with Node.js, Express.js handles heavy workloads and allows the architecture to be tailored to the specific needs of the project. It is therefore also applicable for applications that process a large number of requests in real time - for example, reservation systems, analytics tools or communication platforms.

In addition, the application can be further developed and adapted to new requirements without having to interfere with its basic structure. This flexibility facilitates planning and reduces the cost of future modifications.

Companies that use Express.js include Uber, IBM, Accenture and PayPal. The framework has been applied to a wide range of digital products - from internal tools to large-scale public platforms.
