Using Local storage in phone gap

Question

I wanted to create an mobile app for my web project. I found phonegap. It says Easily create apps using HTML, CSS, and JavaScript. I have not created a mobile app using phone gap before. There are three storage options memory-store.js (MemoryStore), ls-store.js (LocalStorageStore) and websql-store.js (WebSqlStore). I just want to save a token to recognise the user. Which storage is best suited. Is there a better way to build an mobile app.

I appreciate any help.

Using Local Storage will probably be easiest for your needs.

Fundamentally speaking PhoneGap apps are native apps (so they can be distributed through app stores) that simply run a web page or pages. The PhoneGap API then provides JavaScript hooks into the device functions like camera etc. Theres more to it but for now thats the background.

So since the app is essentially a web page (HTML5, CSS, JS) you can make use of LocalStorage (part of HTML5).

Example local storage usage:

Setting values:

localStorage.myname = "Greg";

Getting values:

localStorage.myname; // returns "Greg"

More information here for local storage: http://diveintohtml5.info/storage.html

For Windows Phone 7 : http://docs.phonegap.com/en/3.4.0/cordova_storage_storage.md.html#Storage

The syntax is as below

localStorage.setItem("name", "Alen");

localStorage.getItem("name"); //will return Alen
