What is T-storage?

T-storage is a storage plugin based on modern browsers that encapsulates LocalStorage and SessionStorage.

It borrows the idea of a database and stores the data you need to store according to the three levels of DB_NAME => TABLE_NAME => FIELD_NAME. The time option is added to the data () storage process to limit the length of data storage.

Features

• Store data of the same type together to avoid naming conflicts and variable pollution.
• There is a time limit on the data stored.

Install

Introduced through script tags

https://cdn.jsdelivr.net/npm/t-storage/dist/tstorage.min.js

var storage = window.Tstorage;

Introduced through npm

npm install t-storage -S

import storage from 't-storage'

Usage

// localStorage
storage.data();


// sessionStorage
storage.session.data()

// Most used LocalStorage
let dog1 = storage.data('dog', {
  key: 'dog1',
  value: 'Tom'
})
console.log(dog1);
console.log(storage.data('dog'));
console.log('🐶');

let dog2 = storage.data('dog', {
  key: 'dog2',
  value: {
    name: 'Charlie',
    age: 'tow'
  }
})
console.log(dog2);
console.log(storage.data('dog'));
console.log('🐶');


// The usage of sessionStorage is exactly the same as localStorage
// But sessionStorage does not support the time option
let Fish = storage.session.data('Fish', {
  key: 'Fish1',
  value: 'Gldli'
})
console.log(Fish);
console.log(storage.session.data('Fish'));
console.log('🐠');


// Time-Limited Storage: Time in Seconds
// Don't milliseconds
let cat1 = storage.data('cat', {
  key: 'cat1',
  value: {
    name: 'Cleo',
    age: 'one'
  },
  time: 5 * 60 * 60, // 5 hours
  // time: '2020/3/7 8' // Future time YES
  // time: '2020/3/7 8:59' // Future time YES
  // time: '22020/3/7 08:23:23:14:58' // Malformed
  // ...
})
console.log(cat1);
console.log(storage.data('cat'));
console.log('🐱');

• localStorage uses storage.data (), sessionStorages uses storage.session.data ()
• time parameter you can pass the number of seconds, representing the length of time you want to store, for example you want to store 1 hour, time should pass 1 * 60 * 60
• You can also pass a date format to the time parameter, which means that this storage will be deleted on a certain date in the future. For the date format, see demo
