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.
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
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:
Socket.io can be used for:
Socket.io Key Features:
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:
Hapi.js Main Features:
