ASP.NET MVC 4 with Entity Framework offline with HTML5

Question

I have a form using Entity Framework in MVC. I need to be able use the form offline. How would you push the collected form data to the IndexedDB instead of the server when offline, if even possible?

Answer 1

you can serialize the form data into JSON format and save that into the indexeddb database. Keep in mind that only modern browsers support the indexeddb API. If the data is limited and less than 5 MB I would advice you to take a look at local storage instead. Certainly if you want to support older browsers.

Answer 2

You can use JayData library to managa inbrowser (WebSQL/IndexedDB/HTML5 localstorage) with the same syntax. This tutorial is a good start - How to create a synchronized Online/Offline data application with EntityFramework, JavaScript and JayData
