What’s the proper way to handle forms in Electron?

We use a service (Angular) to process form data in a window. Then notify the remote, if needed.

From your renderer you can send data to the ipc, then in your main.js you catch this event and the passed form data:

// renderer.js
let ipcRenderer = require('electron').ipcRenderer;
ipcRenderer.send('submitForm', formData);

// main.js
ipcMain.on('submitForm', function(event, data) {
   // Access form data here
});

You can also send messages back to the renderer from the main.js.

Either sync:

// main.js
ipcMain.on('submitForm', function(event, data) {
   // Access form data here
   event.returnValue = {"any": "value"};
});

Or async:

// main.js
ipcMain.on('submitForm', function(event, data) {
   // Access form data here
   event.sender.send('formSubmissionResults', results);
});

// renderer.js
ipcRenderer.on('formSubmissionResults', function(event, args) {
   let results = args.body;
});
