Go WebAssembly Boilerplate

This project demonstrates how to run a Go program in the browser using WebAssembly. It outputs "Hello, World!" to the webpage and browser console.

Setup

1. Clone the Repo:

   git clone https://github.com/yourusername/go-wasm-hello-world.git
   cd go-wasm-hello-world
   

2. Get wasm_exec.js:
   Copy it from your Go installation:

   • Windows:

     copy "%GOROOT%\misc\wasm\wasm_exec.js" .
     

   • Mac/Linux:

     cp "$(go env GOROOT)/misc/wasm/wasm_exec.js" .
     

3. Build WebAssembly:

   GOOS=js GOARCH=wasm go build -o hello.wasm hello.go
   

4. Run the Web Server:

   go run server.go
   

5. Open in Browser:
   Visit http://localhost:8080.
