Front-End Web Developer with Redux Salary in 2024

Where is Redux used?

Redux Alternatives

Context API

Built into React for state management, simplifying component-state sharing without 3rd-party libraries.

// Context creation
const MyContext = React.createContext(defaultValue);

// Context Provider

  {/* Components */}


// Context Consumer

  {value => /* render something based on the context value */}

• Integrated in React, no extra library needed.

• Ideal for small to medium-size apps.

• Simpler API compared to Redux.

• Lack of middleware support.

• Not as scalable for complex state management.

• Less dev tools compared to Redux.

MobX

Reactive state management solution leveraging observables for automatic updates of the UI responsive to state changes.

// Defining an observable state
const store = observable({
  count: 0,
  increment() {
    this.count++
  }
});

// Reacting to state changes
autorun(() => {
  console.log(store.count);
});

// Triggering state changes
store.increment();

• Simple and effective for complex states.

• Automatic reactions to state changes.

• Less boilerplate code than Redux.

• Less predictable state mutations.

• Can be overkill for simple state management.

• Potential performance issues with large object trees.

Recoil

A state management library for React providing a more granular approach to state updates with atoms and selectors.

// Atom definition
const textState = atom({
  key: 'textState', // unique ID
  default: '', // default value
});

// Component using atom
function TextInput() {
  const [text, setText] = useRecoilState(textState);

  return (
     setText(e.target.value)} />
  );
}

• Granular control over state and re-rendering.

• Components can subscribe to only parts of the state.

• Built-in async queries support.

• Still in experimental phase.

• Smaller community and ecosystem.

• APIs may change, as it is not fully stable yet.

Quick Facts about Redux

Redux: The State Wrangler

Once upon a time in 2015, two JavaScript cowboys, Dan Abramov and Andrew Clark, corralled the chaos of state management into a harmonious library known as Redux. Inspired by Facebook's Flux and the functional fervor of Elm, they concocted a single source of truth that made state mutations in the web dev saloon predictable and trackable. Behold, the Redux revolution began!

The Immutable Time Machine

Redux brought a sherif-like order to the Wild West of states with its unchanging, or 'immutable', state containers. Every action was like a "Wanted" poster, telegraphing the wanted changes without a single tumbleweed of state being altered along the way. Time-travel debugging? Yep, that futuristic voodoo was baked right in, allowing developers to rewind and replay application states faster than a gunslinger could draw!

The Version Saga

Since its inception, Redux has been through a saga of versions, each more refined than the last. Beginning with its beta release faster than a jackrabbit, it sprinted past v1.0 in the same year of its birth. The community lassoed in with creative addons like Redux-Saga, and like a beloved folk hero, Redux has become an essential tale in the developer's lore, with its epic last stand at version 4.x.x as of my update, holding the fort with new features and fixes.

Here's a snippet of Redux in its natural habitat, taming a wild action in the vast plains of an app:

const ADD_TODO = 'ADD_TODO';

function addTodoAction(text) {
  return {
    type: ADD_TODO,
    text
  };
}

Top 10 Redux Related Tech

1. 
   

   JavaScript

   
   

   Imagine trying to dance without music; that's coding Redux without JavaScript. This programming language is the salsa sauce to your nachos, the foundation of all things Redux. Without it, you're just wiggling your fingers on a keyboard making magic spells.

   
   

   const action = { type: 'DANCE', steps: 'salsa' };

   React

   
   

   React and Redux are like Batman and Robin, peanut butter and jelly, weekends and sleeping in. This library is essential for rendering dynamic UI with states managed beautifully by Redux. It's like having a genie to maintain your app's views while you focus on granting wishes.

   
   

   import React from 'react';
   import { useSelector } from 'react-redux';
   
   const DanceMoves = () => {
     const moves = useSelector((state) => state.moves);
     return <div>{moves}</div>;
   };

   Redux Toolkit

   
   

   Redux Toolkit is like your Swiss Army knife in the wilderness of state management. It packages simple patterns and best practices into one delightful bundle. RTK slices, dices, and makes managing Redux state as easy as pie (mmm, pie...).

   
   

   import { configureStore } from '@reduxjs/toolkit';
   import reducer from './reducer';
   
   const store = configureStore({ reducer });

   Redux DevTools Extension

   
   

   Ever wanted to be a time traveler? Redux DevTools is the closest thing to a DeLorean in the Redux universe, allowing you to jump to different states faster than Marty McFly says "Great Scott!" It's a must-have for nipping bugs in their buggy buds.

   
   

   import { composeWithDevTools } from 'redux-devtools-extension';
   
   const store = createStore(reducer, composeWithDevTools());

   Redux-Saga

   
   

   Picture Redux-Saga as the orchestra conductor for the asynchronous symphony in your app. It makes async flows (like data fetching) as elegant as a tuxedo-clad Maestro waving a baton at a room full of musical prodigies.

   
   

   import { call, put, takeEvery } from 'redux-saga/effects';
   
   function* fetchUser(action) {
     const user = yield call(Api.fetchUser, action.payload.userId);
     yield put({ type: 'USER_FETCH_SUCCEEDED', user });
   }
   
   function* mySaga() {
     yield takeEvery('USER_FETCH_REQUESTED', fetchUser);
   }

1. 
   

   Redux-Thunk

   
   

   Need to kick back and dispatch actions with delayed gratification? Redux-Thunk is like that friend who tells you, "Chill, I got this," and then actually does. It's middleware that allows you to write action creators that return a function instead of an action.

   
   

   const fetchUser = (userId) => {
     return (dispatch) => {
       dispatch({ type: 'USER_FETCH_STARTED' });
       fetchUserById(userId).then(user =>
         dispatch({ type: 'USER_FETCH_SUCCEEDED', user })
       );
     };
   };

   Reselect

   
   

   Imagine having a personal assistant who remembers all your preferences. That's Reselect in the Redux world. It’s a selector library for Redux, optimizing state computation and giving your components what they need without breaking a sweat.

   
   

   import { createSelector } from 'reselect';
   
   const getMoves = state => state.moves;
   const getRhythm = createSelector(
     getMoves,
     moves => moves.filter(move => move.isRhythmic)
   );

   Immutable.js

   
   

   With Immutable.js, your state's untouchability rivals that of King Tut's tomb. It helps keep your state read-only, leading to fewer bugs and a happier coding life (And fewer curses than King Tut's visitors).

   
   

   import { Map } from 'immutable';
   
   const initialState = Map({ isDancing: false });
   function danceReducer(state = initialState, action) {
     switch (action.type) {
       case 'START_DANCING':
         return state.set('isDancing', true);
       default:
         return state;
     }
   }

1. 
   

   Typescript

   
   

   Ever wanted a bouncer at the door of your code checking types like IDs? Enter TypeScript—the strongly typed bouncer for JavaScript. It adds a layer of type safety, reducing runtime errors and making refactors less scary than clowns at a birthday party.

   
   

   interface DanceState {
     isDancing: boolean;
   }
   
   type DanceAction = { type: 'START_DANCING'; };
   
   const danceReducer: Reducer<DanceState, DanceAction> = (state = { isDancing: false }, action) => {
     // reducer logic
   };

   Webpack/Babel

   
   

   Webpack bundles your assets like a financial advisor consolidates your investments. Pair it with Babel, the translator who turns your modern JavaScript into something even Internet Explorer can understand (almost a miracle worker).

   
   

   module.exports = {
     entry: './src/index.js',
     output: {
       path: __dirname + '/dist',
       filename: 'bundle.js'
     },
     module: {
       rules: [{ test: /\.js$/, exclude: /node_modules/, loader: 'babel-loader' }]
     }
   };
