lowdb

vue3+js+lowdb封装,简例

瞎写 写错了告诉我 谢谢

import {Low} from 'lowdb'
import { LocalStorage } from 'lowdb/browser'
import { getUuid } from '@/utils/uuid'
import { cloneDeep } from 'lodash-es'
import { STORE_KEY } from '@/constant'

const adapter = new LocalStorage(STORE_KEY)
const db =new Low(adapter,{
  sys: {
    public: {},
    user: {
      'ghost-uuid': {}
    }
  },
  database: {}
})
export default db
export async function pathInit({
  dbName = 'database',
  path = '',
  user = true,
  validator = () => true,
  defaultValue = ''
}) {
  db.read();
  let uuid = getUuid()
  uuid = uuid === undefined || uuid === null || uuid === '' ? 'ghost-uuid' : (uuid + '')

  const currentPath = `${dbName}.${user ? `user.${uuid}` : 'public'}${path ? `.${path}` : ''}`
  
  
  const value = await getValue(currentPath)
  if (!(value !== undefined && validator(value))) {
    setValue(currentPath, defaultValue)
      
  }
  return currentPath
}
export async function dbSet({
  dbName = 'database',
  path = '',
  value = '',
  user = false
}) {
  let current = await pathInit({dbName,path,user})
  setValue(current, value)
}

async function setValue(path,value){
  await db.read();
  const keys = path.split('.');
  let current = db.data;
  for (let i = 0; i < keys.length - 1; i++) {
    const key = keys[i];
    if (current[key] === undefined) {
      current[key] = {};
    }
    current = current[key];
  }
  current[keys[keys.length - 1]] = value;
  await db.write();
}
