Install

To install SPA Storage Plugin on your app:

with npm

``bash
npm i spa-storage
`

$3



`javascript

// importing spaStorage
import { spaStorage, svelteFunctions, piniaFunctions } from "spa-storage";

// starting forage to use IndexedDB
spaStorage.startForage(undefined, { name: "SS_MY_CUSTOM_NAME", storeName: "SS_CUSTOM_STORE_NAME" });

// starting storage to use localStorage
export { spaStorage, svelteFunctions, piniaFunctions };

`

Now to use it you have just to import it in your stores and use!

#### SVELTE USAGE

`javascript
// DEFINING APP STORE! It could be any store!
// importing spaStorage configured as above
import { writable } from "svelte/store";
import { assign } from "../helpers.js"; // same as cloneDeep from lodash
import { svelteFunctions as SF } from "./storage.js";

const STORAGE_KEY = "SS_APP_STORE";

const storeTemplate = {
themeDark: false,
};

const store = writable(assign({}, storeTemplate));

// ------------------------------------------------------------------------------------------------
// -------------- darkTheme Property ------------------------------------------------------------

async function setThemeDark(themeDark) {
SF.updateStoreKey(store, { themeDark });
await SF.setSvelteStoreInStorage(store, STORAGE_KEY);
}

function getThemeDark() {
return SF.getStoreKey(store, "themeDark");
}

// ------------------------------------------------------------------------------------------------

`

Now to retrieve the information - when you first load the app

`javascript

import { svelteFunctions as SF } from "./storage.js";
import appStore from "./app.js";

export let IS_READY = false;
export async function loadStores() {
if (IS_READY) return true;

try {
// now that we have the store defined we can retrieve information from the browser navigator
// this will load the information from the browser to the app store
await SF.getSvelteStoreInStorage(appStore.store, appStore.STORAGE_KEY);
IS_READY = true;
return true;
} catch (error) {
console.error(error);
throw error;
}
}

export { appStore };

`

#### PINIA USAGE

Pinia is a little more "simple" because it isn't as sofisticated as SVELTE

`javascript

// importing your store definition
import useAppStore from "./app.js";

// exporting for usage in the application
export const appStore = useAppStore();

// loading from browser information to the Pinia store
await getPiniaStoreInStorage(appStore, appStore.$id);

// now you can use subscribe to listen any changes and update the store automatically
// as below
await setPiniaStoreInStorage(
appStore,
appStore.$id,
undefined,
[
"header_options_opened",
"menu_opened",
"menu_filter",
]
);
