As the demand for web development continues to increase, web frameworks in various languages ????are gradually diversified, and the Go language is no exception. Among the many web frameworks in Go language, gin, echo and iris are the three most popular frameworks. In this article, we will compare the pros and cons of these three frameworks to help you choose the right one for your project.

1. gin

gin is a lightweight web framework that features high performance and flexibility. It supports middleware and routing features, which makes it ideal for building RESTful APIs. Its documentation is detailed and easy to learn and use, making it the first choice for many developers.

Advantages:

• High performance and flexibility.
• Routing and middleware support make it ideal for building web applications and RESTful APIs.
• Complete documentation and easy-to-learn and use API.

Disadvantages:

• The author of gin uses a lot of different naming conventions and ways of handling error mechanisms and router settings, which can lead to confusion.
• In terms of view rendering, gin's support is relatively limited.
• The Chinese community is relatively small and it is difficult to obtain rich information and support.

2. echo

echo is another popular web framework and a lightweight framework with excellent performance and flexibility. Unlike gin, echo was developed with a focus on configurability and ease of extensibility, making it a great choice for creating modern web applications.

Advantages:

• Excellent performance and flexibility, easy to expand and adapt.
• Has many practical tools, such as HTML/template rendering, static file serving, etc., supports various plug-ins.
• Supports middleware and routing, ideal for building web applications and RESTful APIs.

Disadvantages:

• For novices, the configurability and scalability of echo may cause some confusion.
• The documentation of the echo framework is relatively not detailed enough, and there are relatively few examples, which can cause some inconvenience to novices.
• Similar to gin, there may be relatively little Chinese information on the echo framework.

3. iris

Iris is a relatively new Go language web framework. Compared with GIN and Echo, Iris is slightly behind in performance. However, Iris has rich features in terms of scalability and maintainability, providing developers with excellent solutions for creating complex web applications.

Advantages:

• It has excellent scalability and maintainability, and supports various middleware and router types.
• Provides powerful command line tools, template engines, and other features related to web applications.
• Many common web development tasks, such as cookie and session management, database abstraction, routers and templates, are fully supported in Iris.

Disadvantages:

• Although Iris is very customizable, it requires a certain learning curve to master all the concepts and techniques.
• Compared with gin and echo, the Iris community has less materials for learning and guidance, so novices may need to spend more time and energy.

Taken together, gin, echo and iris are all excellent Go language web frameworks, and they all have their advantages and disadvantages. gin is suitable for small applications that need to quickly build RESTful APIs, echo is suitable for medium-sized applications, and iris is the first choice for larger projects. Of course, which framework to choose needs to be the best choice based on the needs of the project.
