Various Storage provided by browser now

With Advent of Html5 , we have got various option to cache or store info on client browser. Previously we were having only cookies , which were very restrictive and size of cookies was very small. but now we local storage and session storage as well. and cookies has been talk of past , though it is getting used for various purposes. let's talk about all these

LocalStorage

localStorage is a way to store data on the client’s computer. It allows the saving of key/value pairs in a web browser and it stores data with no expiration date. localStorage can only be accessed via JavaScript, and HTML5. However, the user has the ability to clear the browser data/cache to erase all localStorage data.

Pros:

  • stores data with no expiration date
  • storage limit is about 5MB
  • data is never transferred to the server

Cons:

  • plaintext, hence not secure by design
  • limited to string data, hence need to be serialized
  • can only be read on client-side
