Go has built-in support that makes WASM (WebAssembly) simple and possible. Let’s attempt to use WASM for the first time. A few packages are needed before running this on your system.

Begin by creating a .dockerfile and installing Docker on your host machine:

Here, we have an Alpine-based Go .dockerfile

This is a minimum-sized Docker image with Go already installed.

We will create a working directory called /app and then install git by using the command apk add with the argument --no-cache.

This will prepare our Alpine instance to allow for Git modules to be pulled in later in…
