I have encountered utilizing localStorage in one of my projects back when I was in coding bootcamp. I knew of its existence when we were taught of ...
For further actions, you may consider blocking this person and/or reporting abuse
This is an excellent post on how localStorage works and use it to store data beyond simple strings with
JSON.parseandJSON.stringify❤️With this pattern you can actually use localStorage like an in-browser NoSQL Database
I've exploited this pattern to develop a small Vuejs App allowing a user to store meals and plan which meals to cook the next week
Anyways, I meant to write a post about localStorage, but I think if I write about that app, I will just link back to this post to cover localStorage 😄
Thank you! I still don’t know much besides the basic functionalities but I would love to know more! I’ll keep an eye if you get to post more about localStorage!
Don't use LocalStorage anymore in apps, use IndexedDB
Okay, thanks for the tip.
What are the advantages of indexedDB over localStorage?
It is not blocking javascript I recommend watching youtu.be/NNuTV-gjlZQ
Nice, so thank you for pointing out IndexedDB, since I wasn't familiar with it. One more advantage I have found is, that it can be used with Service Workers (or Web Workers in general) 👍
But if you designed multiple games and stored the high scores of all in local storage then you call clear().
Then will it clear all high scores or only clear that specific games high score in which you call clear() ?
Thanks! Lots I didn't know here, especially about the limitations. One use I had was for users to see a live version of their edits to a profile before committing them. That way if they wanted to return to edits they could without updating the underlying data.
I've been wondering - what are the limitations of using localStorage as if it were global state in a React app (say for folks who want to avoid Redux)?
I tried to use locaStorage as a global state on a project, and it doesn’t automatically reflect the updates or changes in state unlike using Redux or there was somewhat of a delay since it needs to getItem then setItem and then return it.
Congratulations for a awesome post! I was just thinking about this these days, and your article came in perfect timing haha. I was working on a project these days and I was suffering on how to keep variables from a page to other, ans local storage was the way to go!
Oh yes! this is a good thing to point out! Thank you!
A more general topic is Web Storage, that talks about local storage and session storage. Learn more at devopedia.org/web-storage
LocalStorage should not be used anymore in production apps, there is indexeddb.
Even if you're saving only one or two name value pair?
localStorage is extremely easy to use and is secure.
Now, you may want to say something like:
"Cookies should not be used anymore in production apps, there is localStorage."
Even then yes, LocalStorage is blocking the main thread, for this I recommend idb-keyval which lets you store small things like you mentioned in indexeddb also watch this video please to learn more youtu.be/NNuTV-gjlZQ
Thank you, this post clearify what localStorage is.
Thank you!
