🚀 How to use it?

Receiving a byte array

package main

import (
    "io"
    "github.com/LegendaryB/go-native-messaging"
)

func main() {
    host := nativemessaging.NewNativeMessagingHost(nil)

    for {
        b, err := host.ReadBytes()
	
        if err != nil {
	    if err == io.EOF {
		break
	    }
	}
	
	// just echo the received message back to the extension
	host.Write(msg)
    }
}

Note: If you need to write a plain byte array by yourself you can use the following method:
func (host *NativeMessagingHost) WriteBytes(bytes []byte) error

Receiving a complex object

package main

import (
    "io"
    "github.com/LegendaryB/go-native-messaging"
)

type Message struct {
    Value string `json:"value"`
}

func main() {
    host := nativemessaging.NewNativeMessagingHost(nil)
    msg := &Message{}

    for {
        if err := host.Read(msg); err != nil {
	    if err == io.EOF {
		break
	    }
	}

	// just echo the received message back to the extension
	host.Write(msg)
    }
}

Sending a byte array

See last line in section Receiving a byte array.

Sending a complex object

See last line in section Receiving a complex object.

⚙️ Debugging

In the samples above we were passing a nil to the NewNativeMessagingHost method. If you need to receive the error messages you can pass in a io.Writer instance. If the parameter is nil the error messages are written to os.stderr.

Redirecting error messages to a file

package main

import (
    "io"
    "os"
    "github.com/LegendaryB/go-native-messaging"
)

func main() {
    f, _ := os.Create("stderr.txt")
    host := nativemessaging.NewNativeMessagingHost(f)
}
