Building WebAssembly Applications in Go with silicone
Introduction:
silicone is an open-source library designed for creating WebAssembly applications in Go. It offers a simple and user-friendly API that empowers developers to compile and run WebAssembly code seamlessly within their Go applications.
Example: Creating a Basic WebAssembly Application
package main
import (
"fmt"
"github.com/silicone/silicone"
)
func main() {
// Create a WebAssembly application
app := silicone.New("hello.wasm")
// Run the WebAssembly application
result, err := app.Run()
if err != nil {
panic(err)
}
// Print the output of the WebAssembly application
fmt.Println(result)
}
In this example, a straightforward WebAssembly application is created to print the string "Hello, world!"
Example: Performing Calculations with WebAssembly
package main
import (
"fmt"
"github.com/silicone/silicone"
)
func main() {
// Create a WebAssembly application
app := silicone.New("add.wasm")
// Call a function in the WebAssembly application
result, err := app.Call("add", 1, 2)
if err != nil {
panic(err)
}
// Print the output of the WebAssembly application
fmt.Println(result)
}
This example demonstrates a WebAssembly application capable of calculating the sum of two numbers.
Example: Storing and Retrieving Data with WebAssembly
package main
import (
"fmt"
"github.com/silicone/silicone"
)
func main() {
// Create a WebAssembly application
app := silicone.New("store.wasm")
// Store data in the WebAssembly application
err := app.Store("name", "Bard")
if err != nil {
panic(err)
}
// Read data from the WebAssembly application
result, err := app.Load("name")
if err != nil {
panic(err)
}
// Print the data from the WebAssembly application
fmt.Println(result)
}
In this example, a WebAssembly application is used to store and retrieve data.
Example: Interacting between WebAssembly and Go
package main
import (
"fmt"
"github.com/silicone/silicone"
)
func main() {
// Create a WebAssembly application
app := silicone.New("communicate.wasm")
// Set a callback function for the WebAssembly application
app.SetCallback("message", func(message string) {
fmt.Println("Received a message from the WebAssembly application:", message)
})
// Send a message to the WebAssembly application
err := app.Call("send", "Hello, world!")
if err != nil {
panic(err)
}
// Wait for the callback function from the WebAssembly application
app.Wait()
}
This example illustrates a WebAssembly application that can send messages to a Go application and receive callbacks.
