About the lifecycle of dll in edge

[yaphone]

Hello, I am a newer of edge-js, I create a C# dll project, source code as bellow:

namespace NodeDemo
{
    public class Printer
    {
        private string name;

        public async Task<object> Init(string param)
        {
            this.name = param;
            return this.name;
        }

        public async Task<object> SayHello(string param)
        {
            return "Hello, " + name;
        }

        public async Task<object> SayGoodbye(string param)
        {
            return "Goodbye, " + name;
        }
    }
}

And I got the dll file, put it in my node project, then create an api.js like this:

var edge = require('edge')
var path = require('path')

var init = edge.func({
    assemblyFile: path.join(__dirname, '../dll/NodeDemo.dll'),
    typeName: 'NodeDemo.Printer',
    methodName: 'Init'
}) 


var sayHello = edge.func({
    assemblyFile: path.join(__dirname, '../dll/NodeDemo.dll'),
    typeName: 'NodeDemo.Printer',
    methodName: 'SayHello'
}) 

var sayGoodbye = edge.func({
    assemblyFile: path.join(__dirname, '../dll/NodeDemo.dll'),
    typeName: 'NodeDemo.Printer',
    methodName: 'SayGoodbye'
})

module.exports = {
    init,
    sayHello,
    sayGoodbye
}

Finally, I create an index.js like this:

var printer = require('./api/printer')

printer.init('yaphone', function(err, result) {
    if (err) throw err
    console.log(result)
})

printer.sayHello('', function(err, result) {
    if (err) throw err
    console.log(result)
})

printer.sayGoodbye('', function(err, result) {
    if (err) throw err
    console.log(result)
})

I try to run node index.js, and I got output in the console like this:

yaphone
Hello,
Goodbye,

But, my expect output is this:

yaphone
Hello, yaphone
Goodbye, yaphone

I suspect this is related to the life cycle of the dll, because I load the dll three times in node. So, how can I load once, and use the three methods in the dll?

Thx for any replies!

I am looking at using Edge and wanted to see what kind of defects it has.
Looks like the project might be dead (not updated for 2 years).

I noticed your question, but it looks like you are expecting a bunch of async function to behave as if they were sync. What if you await for your init to complete?

THX for your reply. I was a fresher when I ask this question, and I use edge in a wrong way. I write a dll with C#, and I need to use in my electron program, so at last I use 'electron-edge-js'.

In my program, I need to init something like the ca cert and the environment, finally, I write two dlls, electron-edge-js call the first dll, and the first dll call the second to do the init function.

Is there any other way of doing this without using intermediate dll?
