    see 《install go on ubuntu》

 

II. go wasm

 

1. compile

set GOARCH=wasm
set GOOS=js
go build -o helloworld.wasm helloworld.go

 

2. set mime type

/etc/mime.types
Ln132:

application/wasm        wasm

 

 

3. run

(1) other files

1) wasm_exec

to e:\go-project

 

2) helloworld.html

    
        "utf-8">
        
        
    
    

 

 

(2) exec

cd /mnt/e/go-project

 

python -m SimpleHTTPServer 8080

 

http://localhost:8080/helloworld.html

 

 

src: helloworld.go

package main

import (  
    "fmt"  
)


func main() {
    var str string
    var i = 1
    str = "Hello, WebAssembly!"
