Overview of React Typescript with API call example

We will build a React Hooks Typescript Tutorial Application 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 Typescript CRUD Application.

– Create a Tutorial:

– Retrieve all items:

– Click on Edit button to update an item:

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

React Typescript App Diagram with Axios and Router

Let’s see the React Application Diagram that we’re gonna implement:

– The App component is a container with React Router. It has navbar that links to routes paths.

– TutorialsList gets and displays Tutorials.
– Tutorial has form for editing Tutorial’s details based on :id.
– AddTutorial has form for submission new Tutorial.

– They call TutorialDataService functions which use axios to make HTTP requests and receive responses.

If you want to work with Redux like this:

Technology

• React 17/16
• typescript 4.3.5
• react-router-dom 6
• axios 0.26.1
• bootstrap 4.6.0

React Typescript Project structure

Now look at the project directory structure:

Let me explain it briefly.

– package.json contains 5 main modules: react, typescript, react-router-dom, axios & bootstrap.
– App is the container that has Router & navbar.
– types/Tutorial.ts exports ITutorialData interface.
– There are 3 components: TutorialsList, Tutorial, AddTutorial.
– http-common.ts 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.

Setup React Typescript with API call Project

Open cmd at the folder you want to save Project folder, run command:
npx create-react-app react-typescript-api-call --template typescript

After the process is done. We create additional folders and files like the following tree:

---

public

src

components

AddTutorial.tsx

Tutorial.tsx

TutorialsList.tsx

services

TutorialService.ts

types

Tutorial.ts

App.css

App.tsx

index.tsx

package.json

---

Install Bootstrap for React Typescript Project

Run command: npm install [email protected].

Open src/App.tsx 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 Typescript Project

When using Typescript with React.js, we don’t use Proptypes. Typescript is stronger than Propstypes.

– Run the command: npm install react-router-dom.
– Open src/index.tsx and wrap App component by BrowserRouter object.

import ReactDOM from 'react-dom';
import { BrowserRouter } from "react-router-dom";

import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById('root')
);

reportWebVitals();

Add Navbar to React Typescript Project

Open src/App.tsx, this App component is the root container for our application, it will contain a navbar, and also, a Switch object with several Route. Each Route points to a React Component.

import React from "react";
import { Routes, 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";

const App: React.FC = () => {
  return (
    <div>
      <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">
        <Routes>
          <Route path="/" element={<TutorialsList/>} />
          <Route path="/tutorials" element={<TutorialsList/>} />
          <Route path="/add" element={<AddTutorial/>} />
          <Route path="/tutorials/:id" element={<Tutorial/>} />
        </Routes>
      </div>
    </div>
  );
}

export default App;

Define Data Type

Now we need to define the data type for Tutorial. Create and export ITutorialData interface in types/Tutorial.ts.

export default interface ITutorialData {
  id?: any | null,
  title: string,
  description: string,
  published?: boolean,
}

Initialize Axios for React Typescript API call example

Let’s install axios with command: npm install axios.
Under src folder, we create http-common.ts 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.ts

import http from "../http-common";
import ITutorialData from "../types/Tutorial";

const getAll = () => {
  return http.get<Array<ITutorialData>>("/tutorials");
};

const get = (id: any) => {
  return http.get<ITutorialData>(`/tutorials/${id}`);
};

const create = (data: ITutorialData) => {
  return http.post<ITutorialData>("/tutorials", data);
};

const update = (id: any, data: ITutorialData) => {
  return http.put<any>(`/tutorials/${id}`, data);
};

const remove = (id: any) => {
  return http.delete<any>(`/tutorials/${id}`);
};

const removeAll = () => {
  return http.delete<any>(`/tutorials`);
};

const findByTitle = (title: string) => {
  return http.get<Array<ITutorialData>>(`/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.

You can simplify import statement with:
Absolute Import in React

Create React Typescript with API call 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.tsx

import React, { useState, ChangeEvent } from "react";
import TutorialDataService from "../services/TutorialService";
import ITutorialData from '../types/Tutorial';

const AddTutorial: React.FC = () => {
  const initialTutorialState = {
    id: null,
    title: "",
    description: "",
    published: false
  };
  const [tutorial, setTutorial] = useState<ITutorialData>(initialTutorialState);
  const [submitted, setSubmitted] = useState<boolean>(false);

  const handleInputChange = (event: ChangeEvent<HTMLInputElement>) => {
    const { name, value } = event.target;
    setTutorial({ ...tutorial, [name]: value });
  };

  const saveTutorial = () => {
    var data = {
      title: tutorial.title,
      description: tutorial.description
    };

    TutorialDataService.create(data)
      .then((response: any) => {
        setTutorial({
          id: response.data.id,
          title: response.data.title,
          description: response.data.description,
          published: response.data.published
        });
        setSubmitted(true);
        console.log(response.data);
      })
      .catch((e: Error) => {
        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 state and send the POST request to the Web API. It calls TutorialDataService.create() method.

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: React.FC = () => {
  ...

  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 Component

There will be:

• 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.

So we will have following state:

• searchTitle
• tutorials
• currentTutorial and currentIndex

We also need to use 3 TutorialDataService functions:

• getAll()
• removeAll()
• findByTitle()

We’re gonna use the Effect Hook: useEffect() to fetch the data from the Web API. This Hook tells React that the component needs to do something after render or performing the DOM updates. In this effect, we perform data fetching from API.

components/TutorialsList.tsx

import React, { useState, useEffect, ChangeEvent } from "react";
import TutorialDataService from "../services/TutorialService";
import ITutorialData from '../types/Tutorial';

const TutorialsList: React.FC = () => {
  const [tutorials, setTutorials] = useState<Array<ITutorialData>>([]);
  const [currentTutorial, setCurrentTutorial] = useState<ITutorialData | null>(null);
  const [currentIndex, setCurrentIndex] = useState<number>(-1);
  const [searchTitle, setSearchTitle] = useState<string>("");

  useEffect(() => {
    retrieveTutorials();
  }, []);

  const onChangeSearchTitle = (e: ChangeEvent<HTMLInputElement>) => {
    const searchTitle = e.target.value;
    setSearchTitle(searchTitle);
  };

  const retrieveTutorials = () => {
    TutorialDataService.getAll()
      .then((response: any) => {
        setTutorials(response.data);
        console.log(response.data);
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  const refreshList = () => {
    retrieveTutorials();
    setCurrentTutorial(null);
    setCurrentIndex(-1);
  };

  const setActiveTutorial = (tutorial: ITutorialData, index: number) => {
    setCurrentTutorial(tutorial);
    setCurrentIndex(index);
  };

  const removeAllTutorials = () => {
    TutorialDataService.removeAll()
      .then((response: any) => {
        console.log(response.data);
        refreshList();
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  const findByTitle = () => {
    TutorialDataService.findByTitle(searchTitle)
      .then((response: any) => {
        setTutorials(response.data);
        setCurrentTutorial(null);
        setCurrentIndex(-1);
        console.log(response.data);
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  return ( ... )
};

export default TutorialsList;

Let’s continue to implement UI elements:

...
import { Link } from "react-router-dom";

const TutorialsList: React.FC = () => {
  ...

  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.

You can add Pagination to this Page, just follow instruction in the post:
React Pagination using Hooks example

Object details Component

For getting data & update, delete the Tutorial, this component will use 3 TutorialDataService functions:

• get()
• update()
• remove()

We also use the Effect Hook useEffect() to get Tutorial by id in the URL (with the help of useParams() hook).

components/Tutorial.tsx

import React, { useState, useEffect, ChangeEvent } from "react";
import { useParams, useNavigate } from 'react-router-dom';

import TutorialDataService from "../services/TutorialService";
import ITutorialData from "../types/Tutorial";

const Tutorial: React.FC = () => {
  const { id }= useParams();
  let navigate = useNavigate();

  const initialTutorialState = {
    id: null,
    title: "",
    description: "",
    published: false
  };
  const [currentTutorial, setCurrentTutorial] = useState<ITutorialData>(initialTutorialState);
  const [message, setMessage] = useState<string>("");

  const getTutorial = (id: string) => {
    TutorialDataService.get(id)
      .then((response: any) => {
        setCurrentTutorial(response.data);
        console.log(response.data);
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  useEffect(() => {
    if (id)
      getTutorial(id);
  }, [id]);

  const handleInputChange = (event: ChangeEvent) => {
    const { name, value } = event.target;
    setCurrentTutorial({ ...currentTutorial, [name]: value });
  };

  const updatePublished = (status: boolean) => {
    var data = {
      id: currentTutorial.id,
      title: currentTutorial.title,
      description: currentTutorial.description,
      published: status
    };

    TutorialDataService.update(currentTutorial.id, data)
      .then((response: any) => {
        console.log(response.data);
        setCurrentTutorial({ ...currentTutorial, published: status });
        setMessage("The status was updated successfully!");
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  const updateTutorial = () => {
    TutorialDataService.update(currentTutorial.id, currentTutorial)
      .then((response: any) => {
        console.log(response.data);
        setMessage("The tutorial was updated successfully!");
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  const deleteTutorial = () => {
    TutorialDataService.remove(currentTutorial.id)
      .then((response: any) => {
        console.log(response.data);
        navigate("/tutorials");
      })
      .catch((e: Error) => {
        console.log(e);
      });
  };

  return ( ... );
};

export default Tutorial;

And this is the code inside return:

const Tutorial: React.FC<Props> = (props: 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={() => updatePublished(false)}
            >
              UnPublish
            </button>
          ) : (
            <button
              className="badge badge-primary mr-2"
              onClick={() => updatePublished(true)}
            >
              Publish
            </button>

Add CSS style for React Typescript 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 Typescript Client with API call

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 Typescript 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
– Python/Django & MySQL
– Python/Django & PostgreSQL
– Python/Django & MongoDB

Conclusion

Today we’ve built a React Typescript CRUD example with API call successfully with Axios & React Router. Now we can consume REST APIs, display, search and modify data in a clean way. I hope you apply it in your project at ease.

For larger data, you may need to make pagination:
