Learn go-zero from scratch: In-depth understanding of microservice architecture design in vertical fields

With the rapid development of the Internet, microservice architecture is becoming more and more popular in the field of software development. In order to meet the growing business needs, microservice architecture design in vertical fields has become increasingly important. In this article, we will introduce go-zero, a powerful microservice framework, explain in detail how to learn this framework from scratch, and gain an in-depth understanding of microservice architecture design in vertical fields.

1. What is go-zero?

First of all, let us understand what go-zero is. go-zero is a microservice framework built on golang, which is designed to improve productivity and project quality. go-zero has a powerful dependency injection mechanism, pluggable architecture, high-performance RPC and API functions, making it a very good microservice framework.

2. Basic knowledge of go-zero

Before we start to learn go-zero in depth, we need to understand some basic knowledge. First of all, we need to be familiar with the golang programming language and go to the official website (https://golang.org/) to learn golang.

Next, we need to understand some basic knowledge about microservices. Microservices is an architectural style that structures applications as a set of small, independent services, each running in its own process. These services can interact in multiple programming languages ​​and frameworks to implement distributed systems.

3. Install go-zero framework

Before learning go-zero, we need to install it. You can go to the official website of go-zero (https://go-zero.dev/) to download the latest version of go-zero. Before installation, you need to install golang and etcd. After installing golang, etcd and go-zero, we can start using it.

4. Core concepts of go-zero

Before learning go-zero in depth, we need to understand some core concepts. These concepts include:

• Service: Service is a basic concept in go-zero. It represents an application or business logic and can contain multiple Handlers.
• Handler: Handler is another important concept in go-zero. It is the business logic for processing requests and can access various data and functions in the Service.
• Middleware: Middleware is the third core concept in go-zero. It is some operations performed between the request and the response, such as logging, validation, error handling, etc.
• Routing: Routing refers to how to pass the request to the appropriate Handler. In go-zero, routing is implemented by injecting Router.

5. The design idea of ​​go-zero

Before we understand go-zero in depth, let us first understand its design idea. The design idea of ​​go-zero is simple and efficient. It provides some tools and interfaces to help us build high-performance applications. Its design ideas can be summarized as the following points:

• Simple and easy to use: go-zero's design is very simple and easy to get started and use.
• High performance: go-zero has high-performance RPC and API functions, which can support high concurrency and large-scale applications.
• Extensible: go-zero's architecture is pluggable, and various components can be added or removed according to application needs.
• Testable: go-zero provides some tools and interfaces to help with unit testing and performance testing.
• Standardization: go-zero follows certain design specifications to ensure code quality and maintainability.

6. Advantages of go-zero

go-zero has many advantages, which is why it has become a very popular microservice framework. Here are some of the most notable advantages:

• Extensible: go-zero has a pluggable architecture where components can be added or removed based on application needs.
• High performance: go-zero has high-performance RPC and API functions, which can support high concurrency and large-scale applications.
• Easy to use: Since go-zero is written in golang, it is also very easy to learn to use go-zero.
• Utilities: go-zero provides many practical tools, such as rpcx, kratos, etc., that can help developers build microservice architecture faster.

7. Application scenarios of go-zero

go-zero can be used in many scenarios. The following are some of the most common application scenarios:

• Large-scale distributed applications: Because go-zero is high-performance and scalable, it can handle large-scale distributed applications.
• Game Server: go-zero’s high-performance rpc and API capabilities also make it a good choice for building a game server.
• E-commerce platform: For e-commerce platforms, go-zero provides various tools and interfaces to help build high-performance and high-availability e-commerce systems.

8. The future development of go-zero

With the rapid development of microservices, go-zero is also constantly developing. In the future, we can expect go-zero to have the following features:

• Better scalability and pluggability;
• Higher performance and better load balancing;
• Better fault tolerance and fault handling;
• More tools and framework integration.
