What language is best suited for your backend depends on a number of considerations such as scalability, security, maintenance, etc. Among the most widespread backend technologies are Java, Node.js/NestJS and Laravel. Each of these has particular use cases it is suited for and our team of developers can ensure the best backend for your project with all of them.
Since its introduction in 2009 as an open-source project, the interest in Node.js has been steadily rising and peaked especially during the past couple of years. Node.js is neither framework nor programming language, but a runtime environment especially suited for building fast and highly scalable back-end services like APIs and web apps.
What makes Node.js stand out is for one its single thread structure. According to that concept, new requests to the server don’t each require a new thread. Therefore, a single server using Node.js can handle thousands of concurrent connections without having to deal with the burden of thread concurrency that would otherwise cost a lot of resources.
NestJS is a TypeScript-compatible framework for Node.js that provides a comprehensive out-of-the-box architecture made up of Controllers, Providers, Modules, etc. and is thus modeled after Angular. It has definitely been one of the fastest growing Node.js frameworks in the past 3 years in terms of popularity and is backed by a large community and support system.
One of the great advantages of NestJS in comparison with its most widely used counterpart Express.js is the fact that it provides all essential functionality out-of-the-box, which makes it particularly suitable for enterprise apps. It therefore relies far less on external dependencies, much the same the way Angular does in contrast to React.
What’s more, NestJS is based on a concept called platform agnosticism. What is meant by this is that logical parts can be reused with different HTTP frameworks (like Express or Fastify) or even different types of applications (such as microservices, web sockets, etc.) without needing to be specially adapted.
Ensuring that your server-side code and the data it processes are safe from manipulation is a crucial concern of backend development. Security standards therefore have to be enforced in order to avoid attacks in their most common forms:
To counteract vulnerabilities such as these, a number of steps can be taken such as ensuring proper authentication, fine-tuning access rights, using firewalls, strong encryption, data validation, etc. Our backend developers incorporate their security expertise in the entire development process and make sure that your future software adheres to the highest security standards.
