React Use Query

A fast and efficient library for making requests and manage state result in a global level, that give data access from all components of any level, using in React with cache and browser event superpowers. From version 2 was itroduced a custom global state management system, check it out here.

New version of react use query library. Check on npm and github.

🎉 Version 2.0.x is live 🎉

What is React Use Query?

Package to manage all types of queries, using useQuery(url<String>, options<QueryOptions>) hook, with cache control system and granular access to context state. It can be used to optimize all request process.

It is fast and don't make useless request thanks to cache control system. It can also give you access to context state everywhere in your app thanks to useQueryState(name) hook and <QueryProvider>.

If you need to trigger request just after an event like button click, in an efficient way, you should use useQueryEvent(url<String>, options<QueryOptions>) hook instead (example here).

Pagination

import { QueryProvider } from "@aredant/use-query-manager"

ReactDOM.createRoot(document.getElementById('root')).render(
  <QueryProvider>
    <App />

App.jsx

import { useState, useEffect } from 'react'
import { useQuery } from '@aredant/use-query-manager'

const API_URL = "https://dummyjson.com/products";

const _formatSkip = (limit, page) => {
  return limit * (page - 1);
}

const App = () => {
  const [page, setLimit] = useState(1);
  const [limit, setPage] = useState(10);
  const [url, setUrl] = useState(`${API_URL}?limit=${limit}&skip=${_formatSkip(limit, page)}`);

  const { data: products, error, loading, mutate, refresh, cache } = useQuery(url, {

            ))
          }
        </tbody>
      </table>
    </>
  )
}

export default App

Request on event

If you want to trigger the request on event like click you can use useQueryEvent hook. Check the following example:

main.jsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'

import { QueryProvider } from "@aredant/use-query-manager"

ReactDOM.createRoot(document.getElementById('root')).render(
  <QueryProvider>
    <App />
  </QueryProvider>,
)

App.jsx

import { useEffect, useState } from 'react';
import { useQueryState, useQueryEvent } from './hooks';

import "./App.css";

const App = () => {
  const [id, setId] = useState(1);
  const [url, setUrl] = useState(`https://dummyjson.com/products/${id}`);

  const { sendRequest, isSending, data, error, loading, refresh } = useQueryEvent(url, {
    name: "product",
    isDebuggerActivated: true
  });

  useEffect(() => {
    setUrl(`https://dummyjson.com/products/${id}`);
  }, [id])

  return (
    <>
      <div>
        <input type="text" value={id} onInput={({ target }) => setId(target.value)} />
        <button onClick={sendRequest} disabled={isSending}>Send Request</button>
      </div>
      <div>
        {
          loading ? (
            <p>Loading...</p>
          )
          :
          error ? (
            <p>{error.message}</p>
          )
          :
          (
            <pre>
              {
                data && JSON.stringify(data, null, 2)
              }
            </pre>
          )
        }
      </div>
    </>
  )
}

export default App

Of course you can use a combination of useQuery and useQueryEvent inside the same component.

Using selector

main.jsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'

import { QueryProvider } from "@aredant/use-query-manager"

ReactDOM.createRoot(document.getElementById('root')).render(
  <QueryProvider>
    <App />
  </QueryProvider>,
)

App.jsx

import { useEffect } from 'react'
import { useQuery } from '@aredant/use-query-manager'

import InnerComponent from './InnerComponent'

const App = () => {
  const { data, error, loading, mutate, refresh, cache } = useQuery("https://dummyjson.com/products", {
    name: "products", // State name to select right context
    selector: "products", // Selector for first level request data
    method: "GET", // Request method
    headers: {}, // Request headers
    body: undefined, // Request body
    transform: (data) => { // Transform response data
      return data.filter((item) => item.id % 2 === 0);
    },
    pick: (key, value) => { // Pick a portion of data
      if (typeof value === "string" || key === "images") return undefined;
      return value;
    },
    cacheTimeout: 5000, // Timeout to auto-clear cache, 0 if you don't want to auto-clear cache
    isDebuggerActivated: true, // -> Take a look to the inspector console 
  });

  useEffect(() => {
    console.log(data, error, loading);
  }, [data, error, loading]);

  return (
    <>
      <pre>
        <InnerComponent />
      </pre>
    </>
  )
}

export default App

InnerComponent.js

import { useQuerySelector } from '@aredant/use-query-manager'

const InnerComponent = () => {
  const products = useQuerySelector((state) => state.products); // Get just a portion of data by name using query selector callback function

  return (
    <pre>
        {products && JSON.stringify(products, null, 2)}
    </pre>
  )
}

export default InnerComponent;

Global state management

From version 2.0.0 is available a fully featured global state management system.

Work with global State

First of all you need to setup a store using createQueryStore and all dispatchers usign createDispatcher and pass them to QueryProvider as follow:

store.js

import { createQueryStore } from '@aredant/use-query-manager'

export default createQueryStore({
  auth: { // !IMPORTANT Must match with dispatcher name
    token: null,
    user: null,
  }
});

dispatchers/authDispatcher.js

import { createQueryDispatcher } from '@aredant/use-query-manager'

export default createQueryDispatcher({
  name: "auth", // !IMPORTANT Must match with store key object name
  actions: {
    login: (state, payload) => {
      state.token = payload.token;
      state.user = payload.user;
    },
    logout: (state) => {
      state.token = null;
      state.user = null;
    }
  }
});

main.jsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'

import { QueryProvider } from '@aredant/use-query-manager'

import store from './store'
import authDispatcher from './dispatchers/authDispatcher'

import './index.css'

const dispatchers = [
  authDispatcher,
]

ReactDOM.createRoot(document.getElementById('root')).render(
  <QueryProvider store={store} dispatchers={dispatchers}>
    <App />
  </QueryProvider>,
)

Then you can use dispatcher inside any component of your app.

App.jsx

import { useQueryState, useQuerySelector, useQueryDispatcher } from '@aredant/use-query-manager';

import "./App.css";

const App = () => {
  const [data, setData] = useQueryState("auth");

  const auth = useQuerySelector(({ auth }) => auth);
  const { login, logout } = useQueryDispatcher("auth");

  return (
    <>
      <div>
        <p>Token: {auth.token}</p>
        <p>User: {auth.user}</p>
        <button onClick={() => login({ token: "1234abcd", user: "Alex" })}>Login</button>
        <button onClick={() => logout()}>Logout</button>
      </div>
      <div className="container">
        <pre>
            // ====================== <br />
            // -------- DATA -------- <br />
            // ======================
            <br />
            <br />
            {data && JSON.stringify(data, null, 2)}
        </pre>
      </div>
    </>
  )
}

export default App
