Go to Golang to learn the progressive practice of web development

With the development of Internet technology, Web development has become a highly demanded technology. Web development is not only about user interface design, but more importantly, about service performance and stability. At this level, Golang has become a well-recognized framework that is widely used in many fields for its concurrency, simplicity, and maintainability. In this article, we will introduce the progressive practice of using Golang for web development.

1. Determine the development environment

Before we begin, we need to determine which development environment we will use. Golang provides its own integrated development environment, GoLand, and a community development environment based on VS Code. Among these tools, we can choose the development environment we are most familiar with and install relevant plug-ins and extensions according to our needs.

2. Choose Web Framework

An important concept in Golang is Web framework. Web frameworks help organize code and make it easier to maintain. In Golang, I recommend using the three frameworks Gin, Echo or Iris.

Gin is a lightweight web framework that provides high-performance routing and intelligent middleware management. Echo is another very popular web framework that works well on both mobile and web. Iris is an intelligent and flexible web framework for building high-performance web applications.

No matter which framework you choose, you should pay attention to their support for features such as HTTP/2, because these features will have a significant impact on the performance and response time of web applications.

3. Designing API

Before writing an API, take the time to design it carefully. APIs should be carefully designed to achieve the best user experience and program quality.

In API design, you need to first determine the operations that each API should perform, and then create API endpoints based on these operations. If necessary, we can also use middleware and interceptors in the API.

4. Implementing the Web Application

Once the API design is completed, we can start implementing the Web application. In this step we need to:

• Create appropriate routes using the specified web framework.
• Add specific middleware and interceptors that reference other modules.
• Design the database model and then implement the model in the application.
• Write business logic code.
• Verify the code by launching the web application.

5. Testing and debugging applications

During the development process of web applications, we should conduct timely testing and debugging. Here are several ways to test and debug:

• Unit testing. Unit testing is a testing method that can be used to test segments of code.
• Integration Testing. Integration testing is testing the functionality of individual components of an application to ensure they work as expected.
• Manual testing. Manual testing helps us verify that the application behaves as expected.
• debug. Debug your code by using a debugger to find errors and implement better code.

6. Deploying Web Applications

The method for deploying Web applications is related to the needs and circumstances of your development team. The following are several common deployment methods:

• Deployed on the Internet. In this approach, you deploy your application on a cloud server. This method is usually optimal because it allows you to expose your application over the Internet.
• Deployed in the local network. In this approach, you deploy the application into your local network. This approach is typically suitable for small business and private application scenarios.
• Deployed on a separate computer. In this method, you deploy the application to a separate computer. This approach is suitable for a single developer's personal projects.

Summary

Golang is a very powerful programming language and is widely used in the field of web development. In this article, we introduce the progressive practices of how to use Golang for web development, including choosing a development environment, selecting a web framework, designing an API, implementing a web application, testing and debugging, and deploying. These practices should help you better understand web development with Golang and help you implement your own web applications.
