svelte multiple api calls with subsequent click on a button?

It seems that when using electron api each individual press of a button calls the api function x+1 times where x is the times you've pressed the button prior.

Main.js

ipcMain.on('to-main', (event, args) => {
    if(args == "get-file"){
        let result = dialog.showOpenDialogSync({
            title: "Select a folder!",
            properties: ["openDirectory"],
        })
        event.reply('from-main', result.join(""));
    }
    event.reply('from-main', "-")
})

ipcMain.on('to-main', (event, args) => {

            properties: ["openDirectory"],
        })

preload.js

const { contextBridge, ipcRenderer } = require("electron");

console.log('preload.js loaded');
contextBridge.exposeInMainWorld(
    'api', {
    send: (channel, data) => {
        ipcRenderer.send(channel, data)
    },
    sendSync: (channel, data) => {
        ipcRenderer.sendSync(channel, data)
    },
    receive: (channel, func) => {
        ipcRenderer.on(channel, (event, ...args) => func(...args))
    }
});

const { contextBridge, ipcRenderer } = require("electron");

@MartynasXS you're probably better off asking this in the svelte discord

MartynasXS•10mo ago

probably

hyprsonic•10mo ago

Yeah, the support in there is a lot better

    receive: (channel, func) => {
        ipcRenderer.on(channel, (event, ...args) => {
            func(...args)
            ipcRenderer.removeAllListeners(channel)
        })
    }

    receive: (channel, func) => {
        ipcRenderer.on(channel, (event, ...args) => {
            func(...args)
            ipcRenderer.removeAllListeners(channel)
        })
    }
