Are you looking to take your JavaScript development to the next level?
Do long lines of code give you more headaches than solutions?
Well, then, it's time to start nesting!
This in-depth guide will cover what Nest.js is and how it works.
Also, we'll dive into features and benefits to ensure your back-end skills are complete.
Get ready to nest—let's dive in on everything Nest.js!
What is Nest js?
Nest.js is a robust server-side framework for building scalable modern web applications.
Based on Express.js, the popular Node.js framework, Kamil Mysliwiec created Nest.js in 2017.
The framework aims to make developing and maintaining complex web applications easier.
It provides a range of features and tools that make building and managing web apps easier.
Nest.js relies on TypeScript, which combines JavaScript's power with strong typing.
It also supports modern web technologies such as GraphQL and WebSockets.
Plus, Nest.js works great with cloud platforms like AWS, Azure, and Google Cloud Platform.
These services provide scalability, reliability, and cost savings compared to traditional hosting solutions.
Nest.js Features
Nest.js has many features, making it an excellent choice for developers:
- CLI. Nest.js has a powerful command-line interface (CLI) that eases application building, deployment and management.
- Easy-to-use API. Its API ease getting started, with several tools that simplify development and maintenance.
- Built-in Testing. Nest's built-in tools make testing easier to identify and fix issues quickly and debug applications.
- Support. Nest.js supports web technologies such as GraphQL and WebSockets to build applications with these technologies.
- Documentation. With vast documentation, Nest encourages developers to get started.
When to Use Nest.js
Nest.js is an ideal choice for devs aiming to build products with modern architecture.
Here are some examples of how developers can use Nest.js to build powerful web applications:
- Web Servers. Nest.js allows building servers to handle user requests, deliver content or provide APIs access for other apps.
- Web Apps. Nest.js delivers complex webapps with a scalable architecture that includes principles like SOLID, Dependency Injection, and TDD.
- Mobile Apps. Nest.js can build mobile applications that create, store, and retrieve data, with built-in UIs that provide API access.
- GraphQL Servers.Nest.js is excellent for GraphQL servers as it provides many tools to help create and test GraphQL apps quickly and easily.
Pros and Cons of Nest.js
Nest.js is a robust framework that eases complex products' dev and maintenance.
Yet, like any technology, it has its pros and cons. Here are some of the pros and cons of Nest.js:
Pros of Nest.js
- Strong. Nest.js has an easy-to-use API and extensive documentation for devs to get started easily.
- Architecture. The framework saves time with a firm architecture that boosts development processes.
- Settings. Its "batteries included" approach allow developers to not waste time setting their environment.
- JavaScript. Being like other JS frameworks makes it easier for those familiar with its syntax.
Cons of Nest.js
- Tricky. It might be challenging for newbie developers with no Angular background or those who do not use TypeScript.
- Resources. As its newer than frameworks like React.js, resources are available yet limited in comparisson.
- Flexibility. While some third-party libraries allow it, plain Nets is not suitable for cross-platform mobile apps.
The Future of Nestjs
With its seamless TypeScript code, Nest has the potential within back-end development.
Long gone will be the days of coding in several languages down different stacks.
Nest.js allows writing everything they need in one language. In turn, it creates a smooth, fast, and efficient final product.
The library is becoming well known due to its slight learning curve and vast abilities.
As it grows popular and undergoes further improvement, Nest.js will likely look different soon!
Conclusion
Why should you give Nest.js a try?
It’s an ideal framework with out-of-the-box features, enhancing app creation without much code.
Yes, it still needs more online available resources compared to other frameworks.
Nonetheless, its basic structures' make it easy for JS users. Hence, they can take full advantage of Nest.js' benefits.
Setting up a proper environment can be challenging due to the complexity involved.
Still, once you get used to it, there's no doubt that Nest.js will improve your productivity!
