NestJS is database agnostic which means it can work with any database engine. As soon as you choose the relevant one, you just have to connect it in the same way as you would do when using Express or Fastify. If you decide full-stack developer on MongoDB, for example, you can use a dedicated @nestjs/mongoose package. You already know that NestJS is heavily based on TypeScript which is why the vast majority of its features are built around the ES2016 decorators.
Benefits of using NestJS
Perhaps you have to quickly start off the development process with a good boilerplate and adding not only new controllers but also services manually makes you sick. Maybe you want to build a big scalable app that will be easy to maintain. Or you may just want to work in a more effective and convenient way. Regardless of which one is true in your case, it may turn out that Nest.js is just the right answer to your needs. Nest, developed and designed by Kamil Myśliwiec is a minimalistic backend application framework, inspired by Angular.
- Furthermore, there are no limits to what you can build with the framework.
- My role is a backend engineer and come from an ‘enterprise’ culture (i.e. C#, MS stack).
- You can use it to build robust and reliable server-side applications that are both high-performing and secure.
- Finally, we open-sourced our NestJS project boilerplate in GitHub, originally written by Vitaly Melnitchuk, Software Engineer at Argus.
- Typescript allows Javascript users to write cleaner and safer code, making them simple and easy to learn.
What is the entry file of NestJs application?
In this blog, we will look at the key differences between the two so you can decide which one’s ideal for you. We can access the request object by instructing Nest to inject it by adding the @Req() decorator to the handler’s signature. Identify dependencies and connections between modules, and dive deep into the inner workings of your classes. Create loosely coupled, independently deployable services for increased agility and scalability. Introduces design patterns and well-established solutions to the Node.js landscape. We read every piece of feedback, and take your input very seriously.
The open source platform designed for the future. Build enterprise.
After a quick exploration, we understood that the TypeScript files can easily be used with ExpressJS. If one day our team decides to stop using NestJS, we will simply transition to ExpressJS in a matter of a few days. All you need to do to begin the development is to set up a new app and it’s ready to go. Equally importantly, not only does this framework give a huge boost at the very beginning but it also facilitates further steps by defining the proper app architecture. A few other things we like about Nest applications is that the framework is more opinionated than Express, another Node.js framework, or TSOA, which is good for a growing team. Nest offers a lot of flexibility with its Guards and custom Decorators, plus they have more context than basic middleware.
- NestJS is a powerful framework for building efficient and scalable server-side applications.
- We read every piece of feedback, and take your input very seriously.
- Add either the standalone eBook or the eBook and print book bundle to your shopping cart.
- As the team has experience in Typescript, we are looking for a backend solution in Typescript and the go-to solution seems to be nest with express as backbone as the framework.
- In case you’re looking for professional help, you can also hire a Fastify developer via platforms like arc or upstack.
- You can customize this data to your needs by filtering for geography, industry, company size, revenue, technology usage, job postions and more.
As of January 2020, it boasts over 23k GitHub stars and its weekly npm download rate is almost 180k. Both NestJS and Fastify are reliable and high-performing Node.js frameworks. Rather than asking which one’s more popular – it’s better to go with the one that’s most optimized for the job. You may consider looking through their documentation and the source code before making a decision. Nest JS is a server-side/backend framework shaped to support a developer’s productivity. Once we addressed the concerns regarding community size Strong Junior/Middle Nest.js developer job and maturity level, our team decided to check what we can do in a future case when NestJS is no longer developed and maintained.
What you will learn
It quickly gained popularity due to its robust features, TypeScript support, and modular architecture. NestJS has since become a key player in the Node.js ecosystem, offering a structure that accelerates development and improves code maintainability. If you’re still unsure which one would be right for you, let us help. To get started, simply give us a line, and our team will be happy to help. Today, Node.js is among the top 10 JavaScript frameworks, primarily because it’s light, scalable and open-source. Two of the most prominent Node.js frameworks are NestJS and Fastify.
What is the role of migration scripts in TypeORM, and how can you create and run migrations in a NestJS application?
You can develop everything from a minimal web application to a highly intricate enterprise solution. My role is a backend engineer and come from an ‘enterprise’ culture (i.e. C#, MS stack). As the team has experience in Typescript, we are looking for a backend solution in Typescript and the go-to solution seems to be nest with express as backbone as the framework. Nest framework supports middleware, exception filters, pipes, guards, interceptors, GraphQL, Websockets and many other components.
