How to Run GoLang (1.15+) Code in a Browser Using WebAssembly
Why Do We Need WebAssembly?
Today web and mobile applications are the primary vehicles for providing software solutions to users around the world. Applications that we had only in desktop apps today are available for browsers like graphics, photo and video editors; music and video players; and so on.
To use a sophisticated tool in a web browser, sometimes you need to use a specific language, not JavaScript. We have to use a language that provides an easy way to build that type of application. For example, if you want to execute many things in parallel, Go enables a developer to make use of concurrency via goroutines and channels.
In this article, we will learn how to create a project with GoLang in a browser using WebAssembly.
Getting Started
Step 1: Create Our Go File
First, we will create a sample Go file to compile to Wasm (WebAssembly binary code). In this case, we will print “Hello, WebAssembly” in the console. After these initial steps, we will add more content to this file to make it a more useful example.
