Create a favorite list in Ionic Framework - angularjs

Question

I am very new to Ionic Framework. I am learning the framework and have tried to build a simple android app, which displays a simple list using json. Now, I want add a favorite list which will show user selected items in it. When user clicks on a button it should add that item in a favorite list. And When user click on Favorite tab it should show list of all favorite items.
At present I am trying to do this with simple json and global controller. But I am afraid if this is used on android app on a phone it will not store all favorites, it would remove all favourites once app is closed. Can anyone please suggest a better approach towards it.
Many thanks in advance.

Answer 1

I see you tagged the question with local storage, so why not use that? Also, you could use one of the popular mBaaS solutions like Firebase or gunDB.
As for the logic, it's quite easy: you create a new array which you use for storing these favorites (you handle the adding/removing on the favorite button click). You then use the ng-repeat on the Favorites tab to list the favorites array.

The best way to do this would be pouchdb, i m using in same way.!
Install pouchdb using command:
bower install pouchdb
add below line in index.html
<script src="lib/pouchdb/dist/pouchdb.min.js"></script>
make a service:
.factory('FavService', function (UserService) {
var FavService = {};
var localDB;
var user = UserService.getUser();
if (user) {
localDB = new PouchDB('u_' + user.id);
}
FavService.configDbs = function () {
//console.log('config dbs');
var user = UserService.getUser();
if (user) {
localDB = new PouchDB('u_' + user.id);
}
};
FavService.storeToLocal = function (product) { //change function name
if (localDB && product !== "") {
localDB.post(product);
// console.log("Action completed");
} else {
// console.log("Action not completed");
}
};
FavService.getLocalList = function (callback) {
if (localDB) {
localDB.allDocs({
include_docs: true
}).then(function (response) {
// console.log("response :"+JSON.stringify(response));
localDB = response.rows;
callback(response.rows);
}).catch(function () {
callback(null);
});
} else {
FavService.configDbs();
}
};
});
