odd-storage

odd-storage is JavaScript library that has two interfaces (sql and sync) for store data in node.js and browsers.

Example

import oddStorage from 'odd-storage'

let storage = new oddStorage.LocalStorage({prefix: '...'})

$('#change-balance-btn').click(() => {
  storage.withLock(async () => {
    let user = $('#change-balance-user')
    let value = parseInt($('#change-balance-value').val(), 10)
    $('#change-balance-value').val('')

    let isAllow = await request(..., {value: value})
    if (!isAllow) {
      return setTimeout(() => {
        alert(`Action forbidden for user: ${user}, value: ${value}`)
      }, 0)
    }

    let balance = await storage.get(user)
    let newBalance = (balance === null ? 0 : balance) + value

    await storage.set(user, newBalance)
    setTimeout(() => {
      alert(`Balance changed for user: ${user}, new balance: ${balance}`)
    }, 0)
  })
})
