I am facing the sqlite db issue in production mode.
Its working fine on using npm start (on normally run) but not working when i try to create release file for linux using electron-builder build --linux
my package.json file is as follows
{
"name": "test",
"version": "1.0.0",
"description": "test",
"main": "main.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "electron .",
"dist": "electron-builder"
},
"author": "",
"license": "ISC",
"devDependencies": {
"electron": "^13.1.0",
"electron-packager": "^15.2.0"
},
"build": {
"appId": "pkg.dmo.com",
"productName": "sample",
"copyright": "Copyright",
"mac": {
"target": [
"zip"
],
"publish": [

]
},
"win": {
"target": [
"nsis"

},
"linux": {
"target": [

},
"dmg": {
"icon": "build/icon.icns"
}
},
"dependencies": {
"jquery": "^3.6.0",
"sqlite3": "^5.0.2"
}
}
and my sqlite code is as follows:
let $ = (jQuery = require("jquery"));
const sqlite3 = require("sqlite3").verbose();
const path = require('path')
const dbPath = path.join(__dirname, 'testdb.db');
$( document ).ready(function() {
let db = new sqlite3.Database(
dbPath,
sqlite3.OPEN_READWRITE,
(err) => {
if (err) {
console.error(err.message);
}
}
);
db.each("SELECT * FROM Mouse", [], function (err, row) {
console.log("helli");
if (err) {
console.log(err);
return console.error(err.message);
}
console.log("mouse row is =>", row);
});
});
i have tried
var db = new sqlite3.Database( path.resolve(__dirname, 'testdb.db') );
and
var db = new sqlite3.Database( path.join(__dirname,
'testdb.db').replace('/app.asar', '') );
still getting same error in exe but working on local(when npm start)

so I'll keep it short. I've been following this tutorial: https://www.techandstartup.org/tutorials/release-electron-app-on-mac-app-store
However as you'll see we need a pkg file to be uploaded to Transporter for App Store Connect. But when I run 'electron-builder' command I only get an 'Application' .I don't get any .dmg files or .pkg file. This is how my .plis looks like `

Have you ever had this issue:
I was working on my app in development, and everything works fine, but when I created the executable and try to click on my button throw this error:
This the code that is executed when I press my button:
const { exec } = require("child_process");
let myBtn = document.getElementById('my-btn');
myBtn.addEventListener('click', (e) => {
e.preventDefault();
exec("node index.js", (error, data, getter) => {
if(error){
console.log("error",error.message);
return;
}
if(getter){
console.log("data",data);
return;
}
console.log("data",data);
});
});
This the error:
Not recognize the module node and my file index.js
error Command failed: node index.js
internal/modules/cjs/loader.js:1068
throw err;
^

Already updated my node and angular. When doing ng build I get error:
Schema validation failed with the following errors:
Data path "" should NOT have additional properties(scripts).

I have a few JSON files inside a directory named data in the working directory of my Electron project. I succeeded in building the app using electron-build with the following configuration (package.json).
{
"name": "My App",
"version": "0.0.9",
"description": "TEST DESC",
"main": "main.js",
"scripts": {
"start": "electron .",
"pack": "build --dir",
"dist": "build"
}
"author": "Test",
"license": "CC0-1.0",
"build": {
"appId": "test.tester.test",
"directories": {
"app": ""
},
"extraFiles": [
"data"
],
"dmg": {
"contents": [
{
"x": 110,
"y": 150
},
{
"x": 240,
"y": 150,
"type": "link",
"path": "/Applications"
}
]
},
"win": {
"target": "squirrel",
"icon": "build/icon.ico"
}
},
"devDependencies": {
"electron": "~1.7.8",
"electron-builder": "^20.11.1"
},
"dependencies": {
"electron-settings": "^3.1.4",
"jquery": "^3.3.1",
"leveldown": "^3.0.0",
"mkdirp": "^0.5.1",
"shelljs": "^0.8.1"
}
}
I suppose the data directory is not getting added to the build file. Because I am using the files inside of the data directory to render the views in the app, which is not working in the built app. Please suggest a solution.
I am using these JSON files inside the app like this:
fs.readFile('./data/userdata.json', 'utf8', function readFileCallback(err, data) {
if(data == '') { data = '[]'; }
var users = JSON.parse(data);
//Render Code
});
"build": {
"extraResources": [
{
"from": "data",
"to": "data"
}
]
}
After add like this then Electron-builder will copy the data folder to app's resource/data after packing the app. So that you can read the files with
this.
const dataPath =
process.env.NODE_ENV === 'development'
? path.join(__dirname, '../../data')
: path.join(process.resourcesPath, 'data');
fs.readFile(path.join(dataPath,'userdata.json', 'utf8', function readFileCallback(err, data) {
if(data == '') { data = '[]'; }
var users = JSON.parse(data);
//Render Code
});
I ran the node code on this site https://firebase.googleblog.com/2016/08/sending-notifications-between-android.html by using:
node app
I get the following error:
TypeError: request.ref is not a function.
which corresponds to the following line:
sendNotificationToUser("username","new msg",function() {request.ref().remove();} );
This is my package.json file:
{
"name": "myApp",
"version": "1.0.1",
"description": "listen for addition of msgs",
"main": "app.js",
"scripts": {
"start": "node app.js",
"monitor": "nodemon app.js",
"deploy": "gcloud app deploy"
},
"author": "my name",
"engines": {
"node": "~4.2"
},
"license": "ISC",
"dependencies": {
"firebase": "^3.2.1",
"request": "^2.74.0"
}
}
There are indeed some typos in the code. The actual version I run with uses this to remove the messages that have been sent:
requestSnapshot.ref.remove();
The entire listenForNotificationRequests method (in case I made any other edit mistakes while porting to the blog):
function listenForNotificationRequests() {
var requests = ref.child('notificationRequests');
requests.on('child_added', function(requestSnapshot) {
var request = requestSnapshot.val();
sendNotificationToUser(
request.username,
request.message,
function() {
requestSnapshot.ref.remove();
}
);
}, function(error) {
console.error(error);
});
};
