Best practices for building highly available web applications using Go and React

With the popularity of web applications and the increase in demand, building highly available web applications has become increasingly important. Go language and React are two very popular web development tools, both of which are efficient, fast and scalable. In this article, we will explore the best practices for building highly available web applications using these two tools.

1. Develop a stable backend

As a modern system programming language, Go language has built-in support for concurrency and parallel execution, which makes it an ideal choice for building high-end systems. An excellent choice for concurrent and high-availability systems. Here are some best practices for developing a stable backend:

• Design HTTP API: When developing backend services using Go language, it is very important to design the HTTP API well. Make sure your HTTP interface is well documented, standardized, and MIME types, and understand HTTP status codes so you can properly handle error conditions.
• Use modular design: Using modular design makes the development process simpler, more maintainable, and more reusable. The Go language supports modular design perfectly, and you can use packages and interfaces to isolate different parts of the application and improve the maintainability of the application.
• Write testable code: Always consider the testability of your code during development. You can use the Go language's built-in testing framework to write test code to ensure the quality and correctness of your code.

2. Optimize front-end performance

React is a JavaScript library based on component architecture, focusing on building user interfaces. The following are some best practices to pay attention to in React front-end optimization:

• Optimize page rendering: React exists in the form of virtual DOM and optimizes the rendering process by efficiently utilizing virtual DOM, thus improving Rendering performance. However, in order to further improve the page rendering speed, you can take some measures, such as using React.lazy, using shouldComponentUpdate, etc.
• Use code splitting: Code splitting is a technique that saves users time and bandwidth when loading applications. React has a built-in code splitting tool that automatically splits code and optimizes network requests.
• Caching static resources: For static resources, such as images, CSS, and JavaScript files, you can use browser caching to improve first-time loading efficiency. You can use React's built-in webpack or other build tools to optimize your caching strategy.

3. Exception handling and monitoring

Any web-based application may encounter exceptions, and health monitoring of the system is crucial. Here are some best practices for implementing exception handling and monitoring in your applications:

• Unified Logging: Logging errors and exceptions in web applications is very important, you can use The standard library log package accomplishes this task. Each web request should have a unique ID, and this ID should be appended to each log message to facilitate checking for exceptions.
• Real-time monitoring: Real-time monitoring is necessary and is also a good way to detect abnormalities in time. Service containers need to be considered, such as Kubernetes, Docker, etc. These containers can help you quickly deploy and maintain web applications, and provide some common monitoring and alerting tools to make your applications more robust.
• Prevent DDoS attacks: DDoS attacks can crash your application. Therefore, precautions such as using network layer firewalls and load balancers must be taken to handle traffic and stop attackers.

Summary

The Go language and React are powerful tools for building highly available web applications, but in practice, there are many factors to consider. In this article, we explore some best practices, including stable backend development, frontend performance optimization, and application exception handling and monitoring. Applying these best practices will help you build a more robust, efficient, and reliable web application.
