The following command shows how to install egjs-persist using npm.
$ npm install @egjs/persistimport Persist from "@egjs/persist";
const persist = new Persist(key);
// Get information about that page.
const aInfo = persist.get("a");
// Set information about that page.
persist.set("a", "aa");
// Remove information about that page.
persist.remove("a");If the information stored in Persist exceeds the storage quota, a PersistQuotaExceededError error occurs.
The template of the error message is as follows.
Uncaught PersistQuotaExceededError: Setting the value (size: 000) of 'Key' exceeded the SessionStorage's quota. The highest values of SessionStorage are {"key0":0}, {"key1":0}, {"key2":0}.
If you handle the error, you can check the storage information, the key you want to save, and the size of the information.
import Persist, { PersistQuotaExceededError } from "@egjs/persist";
const persist = new Persist(key);
try {
// Get information about that page.
const aInfo = persist.get("a");
// Set information about that page.
persist.set("a", "aa");
// Remove information about that page.
persist.remove("a");
} catch (e) {
if (e instanceof PersistQuotaExceededError) {
console.log(e.key, e.size);
}
}We cannot detect changes in history. The entity using the SPA must respond to changes.
import { updateDepth, replaceDepth } from "@egjs/persist";
// use pushState function
const orgPushState = history.pushState;
Object.defineProperty(history, "pushState", {
configurable: true,
value: (...args) => {
orgPushState.call(history, ...args);
updateDepth();
},
});
// or
history.pushState("/aa", "title", {});
updateDepth();
// use replaceState function
const orgReplaceState = history.replaceState;
Object.defineProperty(history, "replaceState", {
configurable: true,
value: (...args) => {
orgReplaceState.call(history, ...args);
replaceState();
},
});
// or
history.replaceState("/aa", "title", {});
replaceDepth();import React, { useEffect } from "react";
import { Router } from "react-router-dom";
import { createBrowserHistory } from "history";
import { updateDepth } from "@egjs/persist";
const customHistory = createBrowserHistory();
export default function App() {
useEffect(() => customHistory.listen(() => {
updateDepth();
}), []);
return (
<Router history={customHistory}>
...
</Router>
);
}import VueRouter from "vue-router";
import { updateDepth } from "@egjs/persist";
const router = new VueRouter();
router.afterEach(() => {
updateDepth();
