Data Kit by Veen Labs

Highly opinionated utilties for redux/react and async services. Suitable for enterprise level applications to toy apps.

Motivation

To avoid writting repeating/redux-bolier-plate codes.

Installation

# NPM
npm install @veen2/data-kit

# Yarn
yarn add @veen2/data-kit

Peer dependecies

Veen Data Kit expects you already installed the below list of packages. If not you can install yourself

# NPM
npm install axios immer lodash react redux react-redux redux-logger redux-saga


# Yarn
yarn add axios immer lodash react redux react-redux redux-logger redux-saga

Purpose

Veen Datakit is created to addresss following issues

• I have to write a lot of boiler plate codes just to create a Toy app
• Enterpise apps are filled with repeating codes and their coverage
• If I have to make an API call and display the results, then why I have to write lots of call.
• Why I should write code to maintain status of Async operations(like APIS)
• To me Redux thunk looks too ugly
• Redux Toolkit doesn't follow the simplicity of Redux

What's Included

@veen2/data-kit includes two main packages

• AsyncService : For making any kind of API operations
• StateService : To write redux logic, create/dispatch actions. Read data

APIs of AsyncService

• addConfiguration():
• addOperations():
• asyncService:
• types :
• AsyncServiceStatusProvider :
• useAsyncServiceStatus():

APIs of StateService

• createSlice()
• configureStore()
• setup()
• useActions()
• getActions()
• useReset()
• useSliceSelector()
• getSliceSelectors()

Get Started

Lets create an api service using AsyncService

import { AsyncService } from '@veen/data-kit'
const { addConfiguration, addOperations, types } = AsyncService

// Add configurations. (You can have multiple configurations). Check documents for more details
addConfiguration({
  baseUrl: 'http://localhost:8088',
  type: types.webType,
})


// Add apis. You can configure each operation more than just shown in the below examples. Check documents for more details
addOperations({
  createProduct: ['/api/v1/products', 'POST'],
  listProducts: '/api/v1/products',
})

Lets configure redux, add slices and use them in React. Let the fun begin.

createSlice()

import { AsyncService, StateService } from '@veen2/data-kit'

const { asyncService } = AsyncService
const { createSlice } = StateService

const userSlice = createSlice({
  name: 'products',
  initialState: null,
  selectors: {
    getProducts: (s) => s.products || [],
    topProduct: (s) => (s.products || []).sort((a, b) => a - b), // some logic
  },
  actions: {
    // Just api service is mentioned as action. Data will fetched and stored in state
    listProducts: asyncService.listProducts,

    // This is a little complex action, it has three stages. (request, success, failure)
    // All stages are optional
    createProduct: {
      // In request stage we just mentioned the api service
      request: asyncService.createProduct,

      // In success stage we receive the data from request stage. We use it update state ourselves
      success: {
        reducer: (state, action) => {
          // A new product is created. Let's add to the state
          return Array.isArray(state) ? state.push(action.payload) : action.payload
        },
      },

      // Optional failure stage
      failure: {
        // Do something
      },
    },
  },
})

export default userSlice

Configure Store

import { StateService } from '@veen/data-kit'
import productsSlice from './slices/products'
import someOtherSlice from './slices/someOtherSlice'

const { configureStore, setup } = StateService

setup({
  logEnabled: true,
  beforeHandleSaga: function* (action, extraOptions) {
    console.log({ action, extraOptions })
    console.log('Saga starts....')
  },
  afterSuccessHandleSaga: function* () {
    console.log('Saga end....')
  },
})

const store = configureStore(productsSlice, someOtherSlice)

export default store

Configure app

import React from 'react'
import { AsyncService } from '@veen/data-kit'
import { Provider } from 'react-redux'

import './data/apiSetup'
import store from './data/store'
import Products from './components/Products'

const { AsyncServiceStatusProvider } = AsyncService

const Main = () => {
  return (
    <Provider store={store}>
      <AsyncServiceStatusProvider>
        <Products />
      </AsyncServiceStatusProvider>
    </Provider>
  )
}

function App() {
  return <Main />
}

export default App

Add a component

import React from 'react'
import { AsyncService, StateService } from '@veen2/data-kit'

const { useAsyncServiceStatus } = AsyncService
const { useActions, useSliceSelector } = StateService

function Products() {
  const createProductApiStatus = useAsyncServiceStatus('createProduct')
  const listProductsApiStatus = useAsyncServiceStatus('listProducts')

  // There are other ways avaliable to consume useActions then mentioned below
  const { listProducts, createProduct } = useActions('products')

  // There are other ways avaliable to consume useSliceSelector then mentioned below
  const products = useSliceSelector('products:getProducts')
  const topProduct = useSliceSelector('products:topProduct')

  React.useEffect(() => {
    // Fetch items when component mounts
    listProducts()
  }, [])

  return (
    <div>
      <h1>Api Statuses</h1>
      <div>createProduct: {createProductApiStatus}</div>
      <div>listProducts: {listProductsApiStatus}</div>

      <h1>Data List and creation</h1>

      <h3>Top Product</h3>
      <div>
        <button onClick={() => createProduct('Add a product')}>Add product</button>
      </div>
      <div>{topProduct}</div>

      <h3>Products</h3>
      <div>{products.join(' - ')}</div>
    </div>
  )
}

export default Products
