NestJS: the engine behind the systems that keep your business running
What happens behind the scenes of your website or app, and why we use NestJS to build that part
The website or app your customers see is just the storefront. Behind it is a part nobody sees but that makes everything work: it stores sign-ups, checks logins, records orders, calculates prices, sends emails and talks to other systems. This is what we call the back end.
At Ritthec, we build that part with NestJS, a free, open source technology created in 2017. Below we explain, without technical jargon, why it is a great choice for your business.
The engine nobody sees, but everyone feels
When a system is slow, loses data or goes down, the problem is almost always behind the scenes. A well-built back end is what makes sure your customers can sign up, pay and get their confirmation without surprises.
An example close to home: the posts on this blog and our portfolio are published by an API we built with NestJS.
Organized like a well-run company
NestJS splits the system into modules, like the departments of a company: one handles customers, another orders, another payments. Each part has its own responsibility and talks to the others in a predictable way.
In practice, this makes the system easier to maintain and evolve. A new feature comes in without breaking what already works, and a new developer understands the project quickly. The result: lower costs over the years.
- Back end organized in modules, easy to maintain
- Login, permissions and data validation from the start
- TypeScript: fewer errors reaching your customers
- Integrates payments, WhatsApp, email and ERPs
- Used by IBM, Adidas, BMW, GitLab and Decathlon
Security from the ground up
NestJS comes ready for the protections a serious system needs: login, permission levels (who can see or change what) and checks on every piece of data that comes in, before anything is saved.
It also uses TypeScript, a way of programming that catches many mistakes while the system is still being built, not when your customers are already using it. Fewer failures in production mean fewer losses and more trust in your brand.
Ready to connect with other systems and grow
No business works in isolation today. With NestJS, we connect your system to payment providers, WhatsApp, email, Google, management systems (ERP) and whatever else your operation uses.
And when traffic grows, the system grows with it: it can be split into independent parts that serve more and more people, without starting from scratch.
Who else uses NestJS
According to the project's official website, companies like these use NestJS:
• IBM • Adidas • Mercedes-Benz • BMW • GitLab • Decathlon • Roche • Sanofi
If the technology serves companies of this size, it can easily support your business's growth. Need a system, a client area or an integration? Get in touch.
