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));
}
