I am trying to run an app on my local machine but everytime I run it after packaging it throws me following error:
Uncaught Exception:
Error: SQLITE_CANTOPEN: unable to open database file
at Error (native)
If I run it through command line npm start then it works fine.
Here is my code:
var sqlite3 = require('sqlite3').verbose();
var db = new sqlite3.Database('./todo.db');
var http = require('http');
var dispatcher = require('httpdispatcher');
const PORT=6200;
var create_todos = "CREATE TABLE IF NOT EXISTS todos (description TEXT, done BOOL);",
get_todos = "SELECT rowid AS id, description, done FROM todos ORDER BY done ASC, id DESC",
add_todo = "INSERT INTO todos (description, done) VALUES (?, 0)",
delete_todo = "DELETE from todos WHERE rowid=?",
toggle_todo = "UPDATE todos SET description=? WHERE rowid=?";
db.run(create_todos);
function handleRequest(request, response){
try {
//log the request on console
console.log(request.url);
//Disptach
dispatcher.dispatch(request, response);
} catch(err) {
console.log(err);
}
}
//Create a server
var server = http.createServer(handleRequest);
//Lets start our server
server.listen(PORT, function(){
//Callback triggered when server is successfully listening. Hurray!
console.log("Server listening on: http://localhost:%s", PORT);
});
dispatcher.onGet("/get", function(req, res) {
var todos = [];
db.each(get_todos,
function(err, row) {
todos.push({'id' : row.id, 'title' : row.description});
}, function () {
res.end(JSON.stringify(todos));
}
);
res.writeHead('200', {'Content-Type': 'application/json'});
res.end(todos);
});
dispatcher.onPost("/create", function(req, res) {
const data = JSON.parse(req.body);
db.run(add_todo, data.title);
res.writeHead('200', {'Content-Type': 'text/plain'});
res.end('true');
});
dispatcher.onPost("/update", function(req, res) {
const data = JSON.parse(req.body);
db.run(toggle_todo, data.title, data.id);
res.writeHead('200', {'Content-Type': 'text/plain'});
res.end('true');
});
dispatcher.onPost("/delete", function(req, res) {
const data = JSON.parse(req.body);
db.run(delete_todo, data.id);
res.writeHead('200', {'Content-Type': 'text/plain'});
res.end('true');
});
From error it looks like it is not able to find the sqllite db file, but I tried with various different paths. Same error. To generate setup file I am using following command:
electron-packager ./ todo --platform=darwin --arch=x64 --version=0.37.2
