svelte-persisted-store VS mitt

svelte-local-storage-store: A Svelte store that persists to localeStorage

This is a great library for this I’ve used recently if you end up going this route: https://github.com/joshnuss/svelte-local-storage-store

created with https://github.com/joshnuss/svelte-local-storage-store

idb-keyval is a great library for storing simple data in the browser using IndexedDB. secure-ls is great for storing data securely in Local Storage in the browser. There is also svelte-local-storage-store for saving and retrieving data to/from Local Storage in the browser easily with just a svelte store.

Even better, you could use svelte-local-storage-store.

Do you need a persistent writable store? Check out svelte-local-storage-store.

Without SSR, I just used a localstore-backed store for the JWT ( https://github.com/joshnuss/svelte-local-storage-store ) and used onMount() rather than preload()/load() so it only ran authenticated functions on the front end.

I've been using svelte-local-storage-store. It's essentially a wrapper around Svelte store that uses Local Storage, which makes a stores persistent.

Mitt is a small (200 bytes) library that provides the same functionality. It doesn't have many updates, because it's simply perfect and there are not many things to improve there. It gets the job done. Don't be frightened, if in 2 years npm will say it's 2 years old. This library is just perfect with no bloatware. In the worst case, just copy-paste its code to your app.

The implementation can vary widely depending on the requirements. For our application, we will take a small library that will do almost everything for us:

You can use an event bus for this, looks like they removed this functionally from vue 3 so you'll need a 3rd party package like mitt

then we need to install an external library implementing the event emitter interface, in this case mitt

date-fns and mitt (event emitter) are also frequent helpers, but I'm considering dayjs and nanoevents for these cases.

Not sure I understood the post right, bit you may want to check Mitt. It's popular event emitter package that quite nicely deals with this very issue.

As suggested in official docs you could use mitt library to dispatch events across components.

You can use it mitt library. https://github.com/developit/mitt

For situations like this, I use simple event emitter / pubsub library called mitt. It's small and lightweight, however there are many similar libraries that would work.

In this article I want to show you how I have implemented this pattern in my Nuxt 3 applications using Mitt which already provides full TypeScript support. To fully understand what's happening under the hood I recommend to have a quick read of Mitt documentation before continue reading.
