• javascript
• node.js
• electron

• 1 I can see the benefit of both, using an object and passing multiple arguments. However, I would lean more towards passing an object (or even multiple objects as arguments) as it would more closely follow general development guidelines of using data transfer objects. – user3268346 Commented Mar 14, 2019 at 4:55
• Yes, that is what I ended up doing. Personally I like it better this way, since it becomes much simpler to organized your data once received on the other side. Thanks for your comment! – Otto Gutierrez Commented Mar 27, 2019 at 19:29

I would recommend an object for parameter transfer. In consequence, you can also think about implementing a consistent API for your application:

var _myreq = {
  state: 0, //0 is no error, 4 is error with message, etc.
  message: "", //can include error message (if any)
  data: [0,4,6] //application data for request (String, Array, Object)
};
ipc.send('mychannel-functiona', _myreq);

Docs clearly shows that you can pass any number of argument to send.

Send a message to the main process asynchronously via channel, you can also send arbitrary arguments. Arguments will be serialized in JSON internally and hence no functions or prototype chain will be included.

From that point on you have no restrictions on how to use those arbitrary arguments. It depends on your needs, your codebase style etc.

We can pass many arguments for the ipcRenderer, you can refer this page: https://electronjs.org/docs/api/ipc-renderer.
