Can't connect to NeDB on render process Electron

问题

I have problem with connect NeDB to my react-electron app. Now I install NeDB on my project and connect him to electron.js file.

const Datastore = require('nedb');
let db = {};
db.students = new Datastore({
    filename:'./students.json',
    autoload: true
})
db.students.insert({name : "Putin V.V.", year: 1952});

Now I need connect this db to my app.js file. How I can manipulate with this file on render part?

You can achive your idea by using ipc at Electron. I posted an answer before. Please check the below.

how to communicate between react and electron

But here is the pre-requirements.

You should enable the nodeintegration when you are creating the BrowserWindow So at your code, it should be like this

mainWindow = new BrowserWindow({
        width: 1280,
        height: 720,
        minWidth: 900,
        minHeight: 600,
        show: false,
        icon: "",
        webPreferences: {
            nodeIntegration: true
        }
    });

After this, you can use this ipcRenderer at renderer(your react app). If you don't set this option. Then you will face the similar issue as below
