Which nodejs framework is simpler?

Node.js is a very popular server-side JavaScript environment that is efficient and lightweight. When developing Node.js applications, using frameworks can help us quickly build, develop, test, and maintain applications and reduce unnecessary duplication of code. There are many Node.js frameworks to choose from, so how do we choose which one is the easiest?

First of all, we need to make it clear: all Node.js frameworks have their own advantages and applicable scenarios. There is no absolute "which framework is the simplest". Therefore, before choosing a framework, we need to first understand some common Node.js frameworks and understand their characteristics.

1. Express.js
   Express.js is one of the most popular Node.js frameworks out there, with a mature and extensive ecosystem. It is characterized by being lightweight, highly flexible, and can be customized according to needs. Although it uses a basic MVC pattern, it can be integrated with various official or third-party template engines. Express.js brings routing, middleware, error handling and other functions, and a rich plug-in library can meet the various needs of developers. Express.js is well documented, focuses on ease of use, and is easy to learn.
2. Koa.js
   Koa.js is a new framework written by the original author of Express.js. It is based on the compilation of ECMAScript 6 and extensively uses the new features of ES6, such as Generators, Promises, async/await and other syntax to implement code logic. Koa.js is also a lightweight framework. Its functions are not comprehensive, but it ensures that the processing method is process control. Compared with Express.js, the API of Koa.js is simpler and very easy to customize.
3. Hapi.js
   Hapi.js is one of the Node.js frameworks. It is characterized by strict structure and specifications, making it very suitable for large-scale enterprise applications. Hapi.js has an excellent routing and plug-in system. It is also very flexible and powerful in handling authentication, authorization and input validation, which can greatly simplify the development process and maintenance difficulty of the project.
4. Meteor
   Meteor is a full-stack JavaScript framework, which is not only suitable for the server side, but also for the front end. Meteor provides a unified and integrated development platform that can complete front-end and back-end development without switching between different technology stacks. Meteor has complete front-end and back-end communication. The built-in data layer can directly synchronize front-end changes to the database. Meteor's automatic reloading also makes front-end and back-end development convenient.

Based on the characteristics of these frameworks, we can choose a suitable framework based on our own development experience and needs. If you are new to Node.js, Express.js is a good choice; if you want to learn the latest JavaScript syntax and the project needs a process control framework, you can choose Koa.js; if the development team needs to develop large-scale enterprise-level For applications with more standardized and strict requirements, choosing Hapi.js is a wise choice; if you need to quickly develop full-stack applications without switching technology stacks, Meteor is indispensable.

Overall, there is no such question as "which framework is the easiest". Each framework has its pros and cons and has its own unique value in the right context. Before choosing, we need to understand our needs and skill levels, weigh the characteristics of each framework, verify Docker packaging and deployment, and finally make a reasonable choice.
