Golang WebAssembly (WASM) Project Structures - Golang Web Development
In this Golang Web Development Series #12, we'll learn the Golang WebAssembly (WASM) web application project structures that are ideal, scalable, and organized with step by step guide here in Golang's Web Development Series.
Example Syntax on How to Build Golang WASM in different OS:
BUILD WASM IN UBUNTU:
GOOS=js GOARCH=wasm go build -o /var/www/html/maharlikanscode.com/public_html/static/assets/js/auth/auth.wasm main.go
BUILD WASM IN WINDOWS:
set GOOS=js
set GOARCH=wasm
go build -o "C:\maharlikans_code\go\Golang Web Development\gowebapp\static\assets\js\auth\auth.wasm" main.go
