Is it possible to call a function in main.js file from web to electron?

Question

So I have a function in main file main.js which creates Electron BrowserWindow. Lets say:

function HelloWorld(name){
    return 'Hello World! said ' + name;
}

Can I call it in the html page loaded by Electron?

<html>
    <head>
        <script type="text/javascript">
            const hello = require('electron').HelloWorld
        </script>
    </head>
    <body onLoad="alert(hello);">
    </body>
</html>

Can I do that?

Yes you can.

In your main process (probably main.js) put this line in your main process :

global.HelloWorld = function(name){
    return 'Hello World! said ' + name;
}

and in your HTML :

<html>
    <head>
        <script type="text/javascript">
            let {remote} = require('electron');
            const hello = remote.getGlobal("HelloWorld")(); // <-- () this is important
        </script>
    </head>
    <body onLoad="alert(hello);">
    </body>
</html>

But I suggest use ipcMain and ipcRenderer to send data between process.
