It’s easy to understand that the new files belong to a folder called services. Express does not require a specific structure, which can provide flexibility for small or one-person development teams. However, this can become a problem as team size or app complexity grows, especially with developers working on different https://wizardsdev.com/en/vacancy/middle-senior-nestjs-developer/ aspects of the app. Nest can organize your application into self-contained modules, each with its own responsibility. A module can contain related controllers and services and keep them fairly isolated from the rest of your application. The whole of the stack is JS related what helps us to keep development on a track.
Instead of hardcoding configurations and sensitive data directly into your application, environment variables let you abstract these settings. This aids in creating scalable, secure, and maintainable applications. Next.js is an extraordinary framework that utilizes React to build server-side rendered web applications. The majority of developers using Next.js are convinced about its utility and feature range and consider it to be one of the best tools for building websites. I am quite sure that you know the answer to your problem. I have worked with the most popular Nodejs frameworks and I can sure you that there’s no stack better than NestJS (at all).
Angular-like Development
I have decided to use JavaScript & React on the front-end and MySQL for the database. I’m familiar with Node.js, but when I search for ERP (CRM & order mgt) projects on Youtube, I see that most build with Python (Django). One of the most common issues is not finding the expected environment variable.
One advantage I see with the node.js is the number of tutorials available and the ease with which I can code. If you use Nodejs, you should use one more frontend language like reactjs or angularjs. Hey if you are allready familar with nodejs then just go with it.
Using .env File With Dotenv
This means if you are already familiar with Express processing, you’ll be able to adapt your Express middleware to use within Nest. Nest includes an exceptions layer that is responsible for handling all unhandled exceptions across an application. When an exception is not handled by your application code, it is caught by this layer, which sends an appropriate user-friendly response automatically. However, Nest is platform agnostic, meaning it can work with any Node HTTP framework.
It’s important to choose the right framework for your needs, considering what you hope to achieve before getting started. Next.js users have access to an extensive list of tutorials, blog posts, and videos created by the Next.js community. This can be very helpful if you find yourself stuck or needing a refresher on a topic.
What is Express.js?
When a service, interceptor, or controller is created, the CLI creates a spec file. This file includes auto-generated testing bed code, eliminating the need for developers to write additional code for unit testing. We choose Next.js for our React framework because it’s very minimal and has a very organized file structure. Also, it offers key features like zero setups, automatic server rendering and code splitting, typescript support. Our app requires some loading time to process the video, server-side rendering will allow our website to display faster than client-side rending. A misstep can expose sensitive data or disrupt application functionality.
Environment variables provide a way to influence the behavior of software on the system. For Node.js applications, they allow developers to store environment-specific settings, like database connection details or API keys, without having to change the application’s code. Properly setting up environment variables is essential for the security and flexibility of your Node.js applications. By abstracting configurations, you ensure the application behaves differently across various environments without code changes. Node.js environment variables are external values that dictate how an application runs.
A basic Node + Express App
Developers looking to create responsive, secure, and scalable web apps using the Nest.js framework are expected to have a comprehensive knowledge of Javascript. This is because Nest was developed as an extension of Node.js, which provides a server-side platform for developers who wish to use Javascript within their applications. On the other hand, Node.JS is a platform developed on Chrome’s Javascript runtime. However, node.js development services can also be built into fast and scalable applications. With loosely typed languages like PHP, Python, or JavaScript developers might write a bunch of code quickly.
- Through this, we can create domain wise clear boundaries, write reusable modules, and write loosely coupled and maintainable code.
- We’re a new startup so we need to be able to deliver quick changes as we find our product market fit.
- Avoid having multiple mechanisms to set environment variables.
- The code above is messy and the folder structure is not optimal as well.
- By looking at those, you can then decide which language you’ll use for the backend.
I will be using Angular as front-end framework, but for the back-end I am not sure which framework to use between Spring Boot and NestJS. I have worked with Spring Boot before, but my new project contains a lot of I/O operations, in fact it will show a daily report. Regardless, I don’t think “lesser scope” is a valid strike against Node.js here. Node.js fulfills JavaScript’s original vision of an everywhere language and can run anywhere that Java can.

However, as things start to get complex and you add more features to your application, your code will start to get a little messier and harder to manage. This framework is inspired by Angular, so most of what you find in Angular can also be found in Nest, including providers, middleware, components, and services. It is safe to say that Nest can be easily learned by Angular developers for any type of project.
It’s a module, service, controller, pipe, decorators — everything’s syntax, usage, and philosophy exactly matches that of Angular. A frontend Angular developer can easily jump into the backend NEST project — feeling like working in the same project. With the same concept and philosophy for both backend and frontend without much time wasted in context switching.
