Can golang be used as front-end?

Title: Application of Golang in the front-end

Abstract: Golang is a commonly used back-end language, but you may not know that it can also be used in the front-end. This article will introduce the application of Golang in the front-end, including WebAssembly compilation, React Native development and creating single-page applications (SPA).

Text:

As an efficient backend language with strong concurrency features, Golang is very popular in the industry because it can easily build scalable backends app. However, in recent years, developers have started using Golang in the front-end, which may seem a little strange since Golang is usually used for writing high-performance server applications. In this article, we will explore the application of Golang in front-end.

1. WebAssembly compilation

Golang can use WebAssembly compilation to perform high-performance computing in a web browser. WebAssembly is a flexible binary format commonly used to perform computationally intensive tasks efficiently in web browsers. For example, Golang can use WebAssembly to create a high-performance web image editor, or to perform certain tasks that require computational processing, such as machine learning.

The WebAssembly 1.0 specification was released in 2019. As a standard for the Web platform, it can be integrated with JavaScript. Using WebAssembly, Golang's front-end applications can be implemented using WebAssembly-based build tools or using existing JavaScript libraries. Additionally, WebAssembly improves the performance of Golang front-end applications by more than ten times, making them even more powerful.

2. React Native Development

React Native is a popular open source mobile application framework that allows developers to build native applications on different platforms. React Native uses JavaScript as the development language, but Golang also has its application scenarios in React Native. Specifically, Golang can be used to build APIs for React Native applications, while JavaScript is used to get data from the API and render it natively.

One of the features of React Native is cross-platform compatibility, that is, it can be used not only on iOS and Android platforms, but also for the development of web applications. Therefore, using Golang to build APIs for React Native applications allows developers to easily deploy their applications on multiple platforms.

3. Create a single page application (SPA)

A single page application (SPA) is an application developed using front-end technologies such as JavaScript. This application Instead of reloading the entire page through the browser, the program loads only part of the content, which makes the application faster and more responsive. Although SPA usually uses JavaScript as the development language, Golang can also be used to create the backend of SPA.

Golang’s backend support provides security, high performance and scalability for SPA. These features are all very important. Additionally, Golang’s powerful concurrency features provide SPA with higher performance and response time as it can handle multiple client requests.

Conclusion

Although Golang is mainly used for building back-end applications, its front-end application scenarios are also increasing. The advantages of using Golang in WebAssembly, React Native and SPA include efficiency, high performance, scalability and concurrency. So, if you want an efficient language in the front-end to create responsive and performant applications, Golang might be a good choice.
