Overview of React Hooks Redux CRUD example
We will build a React Redux Tutorial Application with Rest API calls in that:
- Each Tutorial has id, title, description, published status.
- We can create, retrieve, update, delete Tutorials.
- There is a Search bar for finding Tutorials by title.
Here are screenshots of our React Redux CRUD Application.
– Create a Tutorial:
– Retrieve all Tutorials:
– Click on Edit button to update a Tutorial:
On this Page, you can:
- change status to Published using Publish button
- delete the item using Delete button
- update the item details with Update button
If you need Form Validation with React Hook Form 7, please visit:

– Search Tutorials by title:
– Check Redux State with Dev-tool:
This React Client consumes the following Web API:
Methods | Urls | Actions |
---|---|---|
POST | /api/tutorials | create new Tutorial |
GET | /api/tutorials | retrieve all Tutorials |
GET | /api/tutorials/:id | retrieve a Tutorial by :id |
PUT | /api/tutorials/:id | update a Tutorial by :id |
DELETE | /api/tutorials/:id | delete a Tutorial by :id |
DELETE | /api/tutorials | delete all Tutorials |
GET | /api/tutorials?title=[keyword] | find all Tutorials which title contains keyword |

React Hooks Redux CRUD Component Diagram with Router & Axios
Now look at the React components that we’re gonna implement:
– The App
component is a container with React Router
. It has navbar
that links to routes paths.
– Three pages that dispatch actions to Redux Thunk Middleware
which uses TutorialDataService
to call Rest API:
TutorialsList
gets and displays Tutorials.Tutorial
has form for editing Tutorial’s details based on:id
.AddTutorial
has form for submission new Tutorial.
– TutorialDataService
uses axios
to make HTTP requests and receive responses.
React Hooks + Redux with API example
This diagram shows how Redux elements work in our React Hooks Application:
We’re gonna create Redux store
for storing tutorials
data. Other React Components will work with the Store via dispatching an action
or getting value using React-Redux Hooks API.
The reducer
will take the action and return new state
.
Technology
- React 17/16
- react-redux 7.2.3
- redux 4.0.5
- redux-thunk 2.3.0
- react-router-dom 5.2.0
- axios 0.21.1
- bootstrap 4
Project Structure
I’m gonna explain it briefly.
– package.json contains main modules: react
, react-router-dom
, react-redux
, redux
, redux-thunk
, axios
& bootstrap
.
– App
is the container that has Router
& navbar.
– There are 3 pages: TutorialsList
, Tutorial
, AddTutorial
.
– http-common.js initializes axios with HTTP base Url and headers.
– TutorialService
has methods for sending HTTP requests to the Apis.
– .env configures port for this React CRUD App.
About Redux elements that we’re gonna use:
– actions folder contains the action creator (tutorials.js for CRUD operations and searching).
– reducers folder contains the reducer (tutorials.js) which updates the application state corresponding to dispatched action.
If you want to use Redux-Toolkit instead, please visit:
Redux-Toolkit CRUD example with React Hooks
Setup React.js Project
Open cmd at the folder you want to save Project folder, run command:
npx create-react-app react-hooks-redux-crud
After the process is done. We create additional folders and files like the following tree:
public
src
actions
types.js
tutorials.js (create/retrieve/update/delete actions)
reducers
index.js
tutorials.js
components
AddTutorial.js
Tutorial.js
TutorialsList.js
services
TutorialService.js
App.css
App.js
index.js
store.js
package.json
Install Bootstrap to React Hooks Redux CRUD App
Run command: npm install bootstrap
.
Open src/App.js and modify the code inside it as following-
import React from "react";
import "bootstrap/dist/css/bootstrap.min.css";
function App() {
return (
...
);
}
export default App;
Add React Router to React Hooks Redux CRUD App
– Run the command: npm install react-router-dom
.
– Open src/App.js and wrap all UI elements by BrowserRouter
object.
...
import { BrowserRouter as Router } from "react-router-dom";
function App() {
return (
<Router>
...
</Router>
);
}
export default App;
The App
component is the root container for our application, it will contain a navbar
inside <Router>
above, and also, a Switch
object with several Route
. Each Route
points to a React Component.
Now App.js looks like:
import React from "react";
import { BrowserRouter as Router, Switch, Route, Link } from "react-router-dom";
import "bootstrap/dist/css/bootstrap.min.css";
import "./App.css";
import AddTutorial from "./components/AddTutorial";
import Tutorial from "./components/Tutorial";
import TutorialsList from "./components/TutorialsList";
function App() {
return (
<Router>
<nav className="navbar navbar-expand navbar-dark bg-dark">
<a href="/tutorials" className="navbar-brand">
bezKoder
</a>
<div className="navbar-nav mr-auto">
<li className="nav-item">
<Link to={"/tutorials"} className="nav-link">
Tutorials
</Link>
</li>
<li className="nav-item">
<Link to={"/add"} className="nav-link">
Add
</Link>
</li>
</div>
</nav>
<div className="container mt-3">
<Switch>
<Route exact path={["/", "/tutorials"]} component={TutorialsList} />
<Route exact path="/add" component={AddTutorial} />
<Route path="/tutorials/:id" component={Tutorial} />
</Switch>
</div>
</Router>
);
}
export default App;
Initialize Axios for React Hooks Redux CRUD HTTP Client
Let’s install axios with command: npm install axios
.
Under src folder, we create http-common.js file with following code:
import axios from "axios";
export default axios.create({
baseURL: "http://localhost:8080/api",
headers: {
"Content-type": "application/json"
}
});
You can change the baseURL
that depends on REST APIs url that your Server configures.
For more details about ways to use Axios, please visit:
Axios request: Get/Post/Put/Delete example
Create Data Service
In this step, we’re gonna create a service that uses axios object above to send HTTP requests.
The service exports CRUD functions and finder method:
- CREATE:
create
- RETRIEVE:
getAll
,get
- UPDATE:
update
- DELETE:
remove
,removeAll
- FINDER:
findByTitle
services/TutorialService.js
import http from "../http-common";
const getAll = () => {
return http.get("/tutorials");
};
const get = id => {
return http.get(`/tutorials/${id}`);
};
const create = data => {
return http.post("/tutorials", data);
};
const update = (id, data) => {
return http.put(`/tutorials/${id}`, data);
};
const remove = id => {
return http.delete(`/tutorials/${id}`);
};
const removeAll = () => {
return http.delete(`/tutorials`);
};
const findByTitle = title => {
return http.get(`/tutorials?title=${title}`);
};
const TutorialService = {
getAll,
get,
create,
update,
remove,
removeAll,
findByTitle
};
export default TutorialService;
We call axios (imported as http) get
, post
, put
, delete
method corresponding to HTTP Requests: GET, POST, PUT, DELETE to make CRUD Operations.
Create Redux Actions
We’re gonna create actions in src/actions folder:
actions
types.js
tutorials.js (create/retrieve/update/delete actions)
Action Types
First we defined some string constant that indicates the type of action being performed.
actions/type.js
export const CREATE_TUTORIAL = "CREATE_TUTORIAL";
export const RETRIEVE_TUTORIALS = "RETRIEVE_TUTORIALS";
export const UPDATE_TUTORIAL = "UPDATE_TUTORIAL";
export const DELETE_TUTORIAL = "DELETE_TUTORIAL";
export const DELETE_ALL_TUTORIALS = "DELETE_ALL_TUTORIALS";
Actions Creator
This is creator for actions related to tutorials. We’re gonna import TutorialDataService
to make asynchronous HTTP requests with trigger dispatch
on the result.
– createTutorial()
- calls the
TutorialDataService.create()
- dispatch
CREATE_TUTORIAL
– retrieveTutorials()
- calls the
TutorialDataService.getAll()
- dispatch
RETRIEVE_TUTORIALS
– updateTutorial()
- calls the
TutorialDataService.update()
- dispatch
UPDATE_TUTORIAL
– deleteTutorial()
- calls the
TutorialDataService.remove()
- dispatch
DELETE_TUTORIAL
– deleteAllTutorials()
- calls the
TutorialDataService.removeAll()
- dispatch
DELETE_ALL_TUTORIALS
– findTutorialsByTitle()
- calls the
TutorialDataService.findByTitle()
- dispatch
RETRIEVE_TUTORIALS
Some action creators return a Promise
for Components using them.
actions/tutorials.js
import {
CREATE_TUTORIAL,
RETRIEVE_TUTORIALS,
UPDATE_TUTORIAL,
DELETE_TUTORIAL,
DELETE_ALL_TUTORIALS,
} from "./types";
import TutorialDataService from "../services/TutorialService";
export const createTutorial = (title, description) => async (dispatch) => {
try {
const res = await TutorialDataService.create({ title, description });
dispatch({
type: CREATE_TUTORIAL,
payload: res.data,
});
return Promise.resolve(res.data);
} catch (err) {
return Promise.reject(err);
}
};
export const retrieveTutorials = () => async (dispatch) => {
try {
const res = await TutorialDataService.getAll();
dispatch({
type: RETRIEVE_TUTORIALS,
payload: res.data,
});
} catch (err) {
console.log(err);
}
};
export const updateTutorial = (id, data) => async (dispatch) => {
try {
const res = await TutorialDataService.update(id, data);
dispatch({
type: UPDATE_TUTORIAL,
payload: data,
});
return Promise.resolve(res.data);
} catch (err) {
return Promise.reject(err);
}
};
export const deleteTutorial = (id) => async (dispatch) => {
try {
await TutorialDataService.remove(id);
dispatch({
type: DELETE_TUTORIAL,
payload: { id },
});
} catch (err) {
console.log(err);
}
};
export const deleteAllTutorials = () => async (dispatch) => {
try {
const res = await TutorialDataService.removeAll();
dispatch({
type: DELETE_ALL_TUTORIALS,
payload: res.data,
});
return Promise.resolve(res.data);
} catch (err) {
return Promise.reject(err);
}
};
export const findTutorialsByTitle = (title) => async (dispatch) => {
try {
const res = await TutorialDataService.findByTitle(title);
dispatch({
type: RETRIEVE_TUTORIALS,
payload: res.data,
});
} catch (err) {
console.log(err);
}
};
You can simplify import statement with:
Absolute Import in React
Create Redux Reducer
There will be a reducer in src/reducers folder, the reducer updates the state corresponding to dispatched Redux actions.
reducers
index.js
tutorials.js
Tutorials Reducer
The tutorials
reducer will update tutorials
state of the Redux store:
reducers/tutorials.js
import {
CREATE_TUTORIAL,
RETRIEVE_TUTORIALS,
UPDATE_TUTORIAL,
DELETE_TUTORIAL,
DELETE_ALL_TUTORIALS,
} from "../actions/types";
const initialState = [];
function tutorialReducer(tutorials = initialState, action) {
const { type, payload } = action;
switch (type) {
case CREATE_TUTORIAL:
return [...tutorials, payload];
case RETRIEVE_TUTORIALS:
return payload;
case UPDATE_TUTORIAL:
return tutorials.map((tutorial) => {
if (tutorial.id === payload.id) {
return {
...tutorial,
...payload,
};
} else {
return tutorial;
}
});
case DELETE_TUTORIAL:
return tutorials.filter(({ id }) => id !== payload.id);
case DELETE_ALL_TUTORIALS:
return [];
default:
return tutorials;
}
};
export default tutorialReducer;
Combine Reducers
reducers/index.js
import { combineReducers } from "redux";
import tutorials from "./tutorials";
export default combineReducers({
tutorials,
});
Because we only have a single store in a Redux application. We use reducer composition instead of many stores to split data handling logic.
For example, if you have Auth Reducer that manages authentication logic, you can use combineReducers()
like following code:
import { combineReducers } from "redux";
import tutorials from "./tutorials";
import auth from "./auth";
export default combineReducers({
tutorials,
auth
});
Create Redux Store
This Store will bring Actions and Reducers together and hold the Application state.
Now we need to install Redux, Thunk Middleware and Redux Devtool Extension.
Run the command:
npm install redux react-redux redux-thunk
npm install --save-dev redux-devtools-extension
In the previous section, we used combineReducers()
to combine 2 reducers into one. Let’s import it, and pass it to createStore()
:
store.js
import { createStore, applyMiddleware } from 'redux';
import { composeWithDevTools } from "redux-devtools-extension";
import thunk from 'redux-thunk';
import rootReducer from './reducers';
const initialState = {};
const middleware = [thunk];
const store = createStore(
rootReducer,
initialState,
composeWithDevTools(applyMiddleware(...middleware))
);
export default store;
Provide State to React Components
We start by wrapping our entire application in a <Provider>
component to make the store
available to its child components.
Open src/index.js
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
...
import { Provider } from 'react-redux';
import store from './store';
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('root')
);
Create React Components
Now we’re gonna build 3 components corresponding to 3 Routes defined before.
Add Object
This component has a Form to submit new Tutorial with 2 fields: title
& description
.
components/AddTutorial.js
import React, { useState } from "react";
import { useDispatch } from "react-redux";
import { createTutorial } from "../actions/tutorials";
const AddTutorial = () => {
const initialTutorialState = {
id: null,
title: "",
description: "",
published: false
};
const [tutorial, setTutorial] = useState(initialTutorialState);
const [submitted, setSubmitted] = useState(false);
const dispatch = useDispatch();
const handleInputChange = event => {
const { name, value } = event.target;
setTutorial({ ...tutorial, [name]: value });
};
const saveTutorial = () => {
const { title, description } = tutorial;
dispatch(createTutorial(title, description))
.then(data => {
setTutorial({
id: data.id,
title: data.title,
description: data.description,
published: data.published
});
setSubmitted(true);
console.log(data);
})
.catch(e => {
console.log(e);
});
};
const newTutorial = () => {
setTutorial(initialTutorialState);
setSubmitted(false);
};
return (
...
);
};
export default AddTutorial;
First, we define and set initial state: tutorial
& submitted
.
Next, we create handleInputChange()
function to track the values of the input and set that state for changes.
We also have a function to get tutorial
local state and send the POST request to the Web API. It dispatchs action with createTutorial()
action creator with useDispatch()
. This hook returns a reference to the dispatch
function from the Redux store.
const dispatch = useDispatch();
dispatch(createTutorial(...));
For return
, we check the submitted
state, if it is true, we show Add button for creating new Tutorial again. Otherwise, a Form with Submit button will display.
...
const AddTutorial = () => {
...
return (
<div className="submit-form">
{submitted ? (
<div>
<h4>You submitted successfully!</h4>
<button className="btn btn-success" onClick={newTutorial}>
Add
</button>
</div>
) : (
<div>
<div className="form-group">
<label htmlFor="title">Title</label>
<input
type="text"
className="form-control"
id="title"
required
value={tutorial.title}
onChange={handleInputChange}
name="title"
/>
</div>
<div className="form-group">
<label htmlFor="description">Description</label>
<input
type="text"
className="form-control"
id="description"
required
value={tutorial.description}
onChange={handleInputChange}
name="description"
/>
</div>
<button onClick={saveTutorial} className="btn btn-success">
Submit
</button>
</div>
)}
</div>
);
};
export default AddTutorial;
List of Objects
This component has:
- a search bar for finding Tutorials by title.
- a tutorials array displayed as a list on the left.
- a selected Tutorial which is shown on the right.
Beside global state tutorials
, we also have following local state:
searchTitle
currentTutorial
andcurrentIndex
We also need to use 3 action creators:
retrieveTutorials
findTutorialsByTitle
deleteAllTutorials
To connect the Redux store with local Component state and props, we use useSelector()
and useDispatch()
.
const tutorials = useSelector(state => state.tutorials);
const dispatch = useDispatch();
When using useSelector
with an inline selector above, a new instance of the selector is created whenever the component is rendered.
Now we can work with tutorials
state and dispatch actions like this:
// use state
tutorials.map(...);
// dispatch actions
dispatch(retrieveTutorials());
dispatch(findTutorialsByTitle(...));
dispatch(deleteAllTutorials(...));
components/TutorialsList.js
import React, { useState, useEffect } from "react";
import { useDispatch, useSelector } from "react-redux";
import {
retrieveTutorials,
findTutorialsByTitle,
deleteAllTutorials,
} from "../actions/tutorials";
const TutorialsList = () => {
const [currentTutorial, setCurrentTutorial] = useState(null);
const [currentIndex, setCurrentIndex] = useState(-1);
const [searchTitle, setSearchTitle] = useState("");
const tutorials = useSelector(state => state.tutorials);
const dispatch = useDispatch();
useEffect(() => {
dispatch(retrieveTutorials());
}, []);
const onChangeSearchTitle = e => {
const searchTitle = e.target.value;
setSearchTitle(searchTitle);
};
const refreshData = () => {
setCurrentTutorial(null);
setCurrentIndex(-1);
};
const setActiveTutorial = (tutorial, index) => {
setCurrentTutorial(tutorial);
setCurrentIndex(index);
};
const removeAllTutorials = () => {
dispatch(deleteAllTutorials())
.then(response => {
console.log(response);
refreshData();
})
.catch(e => {
console.log(e);
});
};
const findByTitle = () => {
refreshData();
dispatch(findTutorialsByTitle(searchTitle));
};
return (
...
);
};
export default TutorialsList;
Let’s continue to implement UI elements:
...
import { Link } from "react-router-dom";
const TutorialsList = () => {
...
return (
<div className="list row">
<div className="col-md-8">
<div className="input-group mb-3">
<input
type="text"
className="form-control"
placeholder="Search by title"
value={searchTitle}
onChange={onChangeSearchTitle}
/>
<div className="input-group-append">
<button
className="btn btn-outline-secondary"
type="button"
onClick={findByTitle}
>
Search
</button>
</div>
</div>
</div>
<div className="col-md-6">
<h4>Tutorials List</h4>
<ul className="list-group">
{tutorials &&
tutorials.map((tutorial, index) => (
<li
className={
"list-group-item " + (index === currentIndex ? "active" : "")
}
onClick={() => setActiveTutorial(tutorial, index)}
key={index}
>
{tutorial.title}
</li>
))}
</ul>
<button
className="m-3 btn btn-sm btn-danger"
onClick={removeAllTutorials}
>
Remove All
</button>
</div>
<div className="col-md-6">
{currentTutorial ? (
<div>
<h4>Tutorial</h4>
<div>
<label>
<strong>Title:</strong>
</label>{" "}
{currentTutorial.title}
</div>
<div>
<label>
<strong>Description:</strong>
</label>{" "}
{currentTutorial.description}
</div>
<div>
<label>
<strong>Status:</strong>
</label>{" "}
{currentTutorial.published ? "Published" : "Pending"}
</div>
<Link
to={"/tutorials/" + currentTutorial.id}
className="badge badge-warning"
>
Edit
</Link>
</div>
) : (
<div>
<br />
<p>Please click on a Tutorial...</p>
</div>
)}
</div>
</div>
);
};
export default TutorialsList;
If you click on Edit button of any Tutorial, the app will direct you to Tutorial page.
We use React Router Link
for accessing that page with url: /tutorials/:id
.
Object details
This component will use TutorialDataService.get()
method in the Effect Hook useEffect()
to get Tutorial by id in the URL.
For update, delete the Tutorial, we work with following action creators:
updateTutorial
deleteTutorial
components/Tutorial.js
import React, { useState, useEffect } from "react";
import { useDispatch } from "react-redux";
import { updateTutorial, deleteTutorial } from "../actions/tutorials";
import TutorialDataService from "../services/TutorialService";
const Tutorial = (props) => {
const initialTutorialState = {
id: null,
title: "",
description: "",
published: false
};
const [currentTutorial, setCurrentTutorial] = useState(initialTutorialState);
const [message, setMessage] = useState("");
const dispatch = useDispatch();
const getTutorial = id => {
TutorialDataService.get(id)
.then(response => {
setCurrentTutorial(response.data);
console.log(response.data);
})
.catch(e => {
console.log(e);
});
};
useEffect(() => {
getTutorial(props.match.params.id);
}, [props.match.params.id]);
const handleInputChange = event => {
const { name, value } = event.target;
setCurrentTutorial({ ...currentTutorial, [name]: value });
};
const updateStatus = status => {
const data = {
id: currentTutorial.id,
title: currentTutorial.title,
description: currentTutorial.description,
published: status
};
dispatch(updateTutorial(currentTutorial.id, data))
.then(response => {
console.log(response);
setCurrentTutorial({ ...currentTutorial, published: status });
setMessage("The status was updated successfully!");
})
.catch(e => {
console.log(e);
});
};
const updateContent = () => {
dispatch(updateTutorial(currentTutorial.id, currentTutorial))
.then(response => {
console.log(response);
setMessage("The tutorial was updated successfully!");
})
.catch(e => {
console.log(e);
});
};
const removeTutorial = () => {
dispatch(deleteTutorial(currentTutorial.id))
.then(() => {
props.history.push("/tutorials");
})
.catch(e => {
console.log(e);
});
};
return (
...
);
};
export default Tutorial;
And this is the code inside return
:
...
const Tutorial = (props) => {
...
return (
<div>
{currentTutorial ? (
<div className="edit-form">
<h4>Tutorial</h4>
<form>
<div className="form-group">
<label htmlFor="title">Title</label>
<input
type="text"
className="form-control"
id="title"
name="title"
value={currentTutorial.title}
onChange={handleInputChange}
/>
</div>
<div className="form-group">
<label htmlFor="description">Description</label>
<input
type="text"
className="form-control"
id="description"
name="description"
value={currentTutorial.description}
onChange={handleInputChange}
/>
</div>
<div className="form-group">
<label>
<strong>Status:</strong>
</label>
{currentTutorial.published ? "Published" : "Pending"}
</div>
</form>
{currentTutorial.published ? (
<button
className="badge badge-primary mr-2"
onClick={() => updateStatus(false)}
>
UnPublish
</button>
) : (
<button
className="badge badge-primary mr-2"
onClick={() => updateStatus(true)}
>
Publish
</button>
)}
<button className="badge badge-danger mr-2" onClick={removeTutorial}>
Delete
</button>
<button
type="submit"
className="badge badge-success"
onClick={updateContent}
>
Update
</button>
<p>{message}</p>
</div>
) : (
<div>
<br />
<p>Please click on a Tutorial...</p>
</div>
)}
</div>
);
};
export default Tutorial;
Add CSS style for React Components
Open src/App.css and write CSS code as following:
.list {
text-align: left;
max-width: 750px;
margin: auto;
}
.submit-form {
max-width: 300px;
margin: auto;
}
.edit-form {
max-width: 300px;
margin: auto;
}
Configure Port for React Redux CRUD with Web API
Because most of HTTP Server use CORS configuration that accepts resource sharing retrictted to some sites or ports, so we also need to configure port for our App.
In project folder, create .env file with following content:
PORT=8081
Now we’ve set our app running at port 8081
.
Run React Hooks Redux CRUD App
You can run our App with command: npm start
.
If the process is successful, open Browser with Url: http://localhost:8081/
and check it.
This React Client will work well with following back-end Rest APIs:
– Express, Sequelize & MySQL
– Express, Sequelize & PostgreSQL
– Express, Sequelize & SQL Server
– Express & MongoDb
– Spring Boot & MySQL
– Spring Boot & PostgreSQL
– Spring Boot & MongoDB
– Spring Boot & SQL Server
– Spring Boot & H2
– Spring Boot & Cassandra
– Spring Boot & Oracle
– Django & MySQL
– Django & PostgreSQL
– Django & MongoDB
Conclusion
Today we’ve built a React Hooks Redux CRUD example successfully with React Router & Axios. Now we can consume REST APIs, display, search and modify data with Redux Store in a clean way. I hope you can make API call (GET/POST/PUT/DELETE) in your project at ease.

There is warnings on src\components\TutorialsList.js
warning message: Line 20:6: React Hook useEffect has a missing dependency: ‘dispatch’. Either include it or remove the dependency array react-hooks/exhaustive-deps
how to fix it?
solution
Can you briefly describe what is happening with this solution and why it is needed? Thank you!
Best solution is to remove array argument. It should be as follows:
useEffect(() => {
dispatch(retrieveUsers());
});
Instead of:
useEffect(() => {
dispatch(retrieveUsers());
},[]);
And this is already suggested in warning text.
Removing the second argument will cause useEffect to be called continuously. If you console.log(‘in on useEffect’); you will see in the terminal that it just keeps calling this function.
I tried adding “dispatch” to the second argument like this:
useEffect(() => {
dispatch(retrieveManagers());
}, [dispatch]);
and it is working just fine.
