Which nodejs framework is easy to use as backend?

With the advent of the mobile Internet era, Web applications are becoming more and more important. In web applications, Node.js has gained popularity as a backend development. Node.js is single-threaded, event-driven, and non-blocking I/O, making it highly efficient and scalable in web application development. Node.js allows us to develop backend applications quickly, easily and elegantly.

However, for beginners and developers, choosing the right framework can save time and increase productivity. Before choosing a Node.js framework that suits you, it is worth mentioning that each framework has its own unique advantages and disadvantages, and you need to choose based on the actual situation.

This article will provide some popular Node.js frameworks and discuss their advantages and disadvantages, as well as their applicable application scenarios.

1. Express

Express is one of the most popular Node.js frameworks and is widely used. It has good performance and scalability, and has an active community that provides a large number of plug-ins and middleware. It is also one of the most popular web application frameworks that helps developers easily build Node.js-based web applications.

Advantages:

• Easy to learn and quick to use.
• Rich HTTP request methods and middleware.
• High degree of freedom, you can expand functions according to your own needs.

Disadvantages:

• Many functions in Express need to be implemented through middleware. This makes the code base complex, especially when multiple middlewares are required.
• Some manual configuration is required to ensure the security of the code.
• Some people think that the Express framework is too verbose and lacks simplicity.

Applicable scenarios:

• For developers who need to build small to medium-sized web applications, Express is an essential choice.
• Express is also a good choice for developers who need a deeper understanding of how web applications work.

2. Koa

Koa is another popular Node.js framework that was designed by the original author of Express. The Koa framework was created to take better advantage of ES6 and ES7, making it simpler and easier to use. It uses asynchronous functions to handle requests and responses, making the code look cleaner.

Advantages:

• Extremely high flexibility – any functionality can be easily extended through middleware solutions.
• More concise than Express.
• is more elegant and concise in terms of code.
• It has more Promise function than Express framework.

Disadvantages:

• The flexibility and simplicity of the Koa framework make it more developer-specific than Express.
• Koa does not support the more common callback function like Express.

Applicable scenarios:

• Koa is suitable for developers of large-scale web applications and APIs who require higher scalability and efficiency.
• For developers who want to write more elegant code, Koa is a good choice.

3. Nest.js

Nest.js is a new popular Node.js framework based on Angular’s ​​architectural pattern. Nest.js is considered as one of the modern, robust and scalable web application platforms. It has extensive plugins and support and is known for its reliability and scalability.

Advantages:

• Based on the TypeScript framework, type checking is provided to make the code more stable and reliable.
• Supports a wide range of plug-ins that are easy to develop.
• Nest also has rich CLI tools. With these tools, you can create, manage and deploy your applications more easily.
• Built-in dependency injection function.

Disadvantages:

• Nest may be a bit difficult for beginners. Because it makes extensive use of design patterns and requires proficiency in how to use it to extend application functionality.
• If you have no experience using Angular to develop web applications, you may encounter some challenges when using Nest.

Applicable scenarios:

• For developers who need to build large-scale web applications, Nest is the best choice.
• Nest is a great tool for developers who are familiar with Angular.

4. Meteor

Meteor is a popular full-stack framework. It allows you to handle front-end and back-end in one code base and allows real-time data delivery. Meteor also allows you to use a range of plugins and handy tools to speed up your development.

Advantages:

• Meteor has a full JavaScript stack that can handle both front-end and back-end.
• It provides very good tools and utilities for real-time data.
• You can use Meteor's integrated approach to easily develop web and mobile applications.

Disadvantages:

• Meteor has a higher threshold and a certain learning curve.
• It is relatively less flexible than other Node.js frameworks.

Applicable scenarios:

• Meteor is best suited for web applications that need to process real-time data.
• Meteor is a good choice for developers who need to build responsive web applications.

Summarize

The above are some popular frameworks in Node.js. Each framework has its unique advantages and limitations. You can choose one or more of these depending on your project needs and skill level.

• For beginners, Express and Koa are both good choices.
• If you need to process large amounts of real-time data, Meteor may be your best choice.
• If you need a more efficient, scalable and efficient framework, there is no better choice than Nest.

No matter which framework you choose, using and mastering these frameworks will help you build Node.js applications more efficiently.
