We all love localstorage, no database needed to store simple things for our user.
But what if the data is more than a string or number?
Let’s see how to store and read object in localstorage?
How to store object in localstorage
We need to turn json into a string with JSON.stringify
localstorage.setItem(key, JSON.stringify(val));
How to read/retrieve object from localstorage
We need to parse into json with JSON.parse
JSON.parse(localstorage.getItem(key))
Bonus: Helper for read and write objects in localstorage
function getObjectLS(key) {
return JSON.parse(localStorage.getItem(key))
}
function setObjectLS(key, val) {
localStorage.setItem(key, JSON.stringify(val));
}
