Dasmet

Dasmet is a light weight data management(e.g. store, dict) util library

if you hate ugly API usage for plain data store management, you may try dasmet

| | vuex or other state management system | data model | dasmet | | ----------------------------------- | ------------------------------------- | ---------- | ---------------- | | data init | ☹️ Complicated | 🙂 Simple | 🙂 Simple | | accessing data | 😐 A little complicated | 🙂 Simple | 🙂 Simple | | setting by k-v | Must via commit(maybe complicated) | 🙂 Simple | 🙂 Simple | | setting by object merging | Must via commit(maybe complicated) | ❌ No | ✅ Yes yet simple | | data snapshot | ✅ Yes | ❌ No | ❌ No | | weight | ☹️ Heavy | 🙂 Light | 🙂 Light | | native Array bonus util support | ❌ No | ❌ No | ✅ Yes |

Tip: Please note that if you need data snapshot, a state management system is still better solution. But if you are aware of that #YouMayNotNeedStateManagement#, you should avoid using state management system in you project from now.

Features

• Easy API design as first-class rule
• Array.get() like map

Install

Install it via npm

npm i -S @youngbeen/dasmet

Import

import { newStore } from '@youngbeen/dasmet'

Usage

Store Usage

// generating data store instance
let userStore = newStore({
  userName: '',
  userId: ''
})

// setting value by k-v
userStore.set('userName', 'you')
userStore.set('newKey', 1)
/* -> {
  userName: 'you',
  userId: '',
  newKey: 1
} 
*/
// setting value by object merging (merge value)
userStore.set({
  userName: 'youngbeen',
  userId: '21'
})
/* -> {
  userName: 'youngbeen',
  userId: '21',
  newKey: 1
} 
*/

// accessing value
userStore.get('userName') // -> 'youngbeen'
// or
userStore.value.userId // -> '21'

Dict Usage

New ES6+ Array has many amazing features like filter, map etc. In a dict model we ofter want to get an item directly, however it is not convenient using dict.someDictTypes.find(item => item.key === targetKey)

Dasmet brings a native support(via Array.prototype) of Array.get method

Array.get(value, [keyName])

e.g.

// finding item by specific value
dict.someDictTypes.get(targetKey)

Meanwhile, you can choose which key to get

dict.someDictTypes.get(targetKey, myKeyName)

Tip: if keyName not set, default get priority is id > key > value
