Use localstorage with faster read.

localStorage

class LocalStorage {
    private cache: Record<string, any> = {};
    static instance: any;

    constructor() {        
        if (!!LocalStorage.instance) {
            return LocalStorage.instance;
        }        
        LocalStorage.instance = this;            
        this.hydratedCache();
        return this;
    }

    get(key: string) {
        if (this.cache[key]) {
            return this.cache[key];
        }

        const inLS = localStorage.getItem(key);

        if (inLS) {
            return JSON.parse(inLS);
        }

        return null;
    }

    set(key: string, value: Record<string, any> | string | number) {
        this.cache[key] = value;
        localStorage.setItem(key, JSON.stringify(value));
    }

    remove(key: string) {
        delete this.cache[key];
        localStorage.removeItem(key);
    }

    private hydratedCache() {
        try {
            const cache = {};
            const keys = Object.keys(localStorage);
            for (let i in keys) {
                const key = keys[i];
                this.cache[key] = JSON.parse(localStorage[key])
            }
        }catch(err) {
            console.log('failed to hydratedCache', err)
        }        
    }
