What are the node.js background frameworks?

Node background frameworks include: 1. Koa, an open source Node web framework that uses Generator to implement middleware process control and try/catch to enhance exception handling; 2. Nest, an open source framework for building efficient , a framework for scalable Node server-side applications; 3. Socket, a framework used to create real-time two-way communication between the client and the server; 4. Sails, a very solid Node framework that provides the ability to build any scale All the features a web application needs.

The operating environment of this tutorial: Windows 7 system, nodejs version 16, DELL G3 computer.

Node is the most agile server-side web application platform because it provides application development companies with the convenience of building a scalable single programming language web platform. It is one of the most popular open source JavaScript runtime frameworks and has cross-platform properties, allowing us to run code outside the browser.

node.js background framework

1. Koa

Koa is more like a " Frame of frames” because it’s so simple and extremely freeing in itself. Koa uses Generator to implement middleware process control and try/catch to enhance exception handling. At the same time, you can no longer see complex callbacks in the Koa framework. The Koa framework itself is very small and only packages some necessary functions. There is no process management and it needs to be used with third-party packages.

Koa.js can be used for:

• Front-end system

• Back-end system

• Hybrid system

Koa.js main features:

• represents modernity And the future

• Smaller size compared to all Node.js frameworks.

• Has a built-in error catcher to prevent website crashes.

• Use the context object, which holds both request and response objects.

2. Nest

Nest is a server-side application for building efficient and scalable Node.js The framework of the program. A truly complete, industrial-grade framework. It uses progressive JavaScript, has built-in and full support for TypeScript (but still allows developers to write code in pure JavaScript) and combines elements of OOP (Object-Oriented Programming), FP (Functional Programming) and FRP (Functional Reactive Programming). Provide a complete solution, from code to module splitting to microservice model. And the underlying HTTP platform of its framework is implemented based on Express by default, so there is no need to worry about the lack of third-party libraries. It also provides an out-of-the-box application architecture that allows developers and teams to create applications that are highly testable, scalable, loosely coupled, and easy to maintain.

Nest.js can be used to:

• Write clearer and reusable code.

• Write code with higher-level structures, such as interceptors, filters, pipes, etc.;

• Write code that is extensible, testable, and Loose applications.

Nest.js Main Features

• ##Easy to extend: can be used with other libraries.

• Allows developers to code entirely in pure JavaScript.

• combines the characteristics of functional programming, object-oriented programming and reactive programming.

• Open framework API to help developers use various third-party modules on various platforms.

• It has a detailed and well-maintained documentation.

3、Total

Total.js is a good way to help you create Node.js, Web pages/applications The framework also supports the MVC architecture.

4. Socket

Socket.io is a framework used to create real-time two-way communication between the client and server. To do this, the client needs to install http://Socket.io in the browser, and the server needs to integrate the http://Socket.io package. This allows data to be shared in millions of forms. However, the most popular method is still JSON.

Socket.io consists of two parts:

• JavaScript Service: Node.js

• JavaScript Client Library: Node.js

Note: Socket.io is also compatible with many other languages, such as Java, C, Swift, Dart, .Net and Python.

Socket.io can be used for:

• Various namespaces

• Broadcast

• Event handling

• Error handling

• Logging and debugging

• Chat Application

• Internal

Socket.io Key Features:

• Encode information into named JSON or binary events.

• Add "real time" capabilities to your application.

• Supports automatic reconnection

• Excellent speed and reliability

• Instant messaging and chat

5. Sails

Sails is a very solid Node.js framework that provides the ability to build web applications of any scale. All features needed. The Express framework is used at the bottom to provide processing of HTTP requests, and the Socket.IO framework is used to process WebSocket requests. It also implements ORM functionality, allowing your application to switch from one backend database to another without making major modifications. Sails is particularly suitable for developing applications that have high requirements for real-time updates of data, and its annotations are so detailed that you may not know how to use them. A framework that cares about developers can last long.

6, Egg

Egg is based on Koa, constrains and standardizes team development, and its core is to help development teams and developers reduce development and maintenance costs . It provides the ability to customize the upper-layer framework based on Egg, a highly scalable plug-in mechanism, built-in multi-process management,

excellent performance, and stable framework. It has been used in many Alibaba product lines, which can prove its safety and reliability, so please feel free to use it.

7. Hapi.js

##Hapi.js continues all the advantages of Express.JS and adds some features. Developers no longer have to waste time building infrastructure and can use this time to write reusable application logic. Some of its advantages: fixing bugs and adding new features does not take time, building APIs for different types of clients, plugin-based architecture makes scaling easy, better control over how requests are processed.

Hapi.js can be used for:

• Website

• HTTP proxy application

• Application Programming Interface Service

Hapi.js Main Features:

• Input validation

• Log

• Error handling

• Code reusability

• Cache

• No external dependencies

• Configuration-based functionality

• Integrated framework: Provides comprehensive authentication and authorization API support in the Node framework.
