Display response from request using Fetch API in Reactjs

by vsasikalabe Updated: Jan 24, 2023

In this kit, we're going to see how to display response from request using Fetch API in Reactjs with simple steps.The Fetch API through the fetch() method allows us to make an HTTP request to the backend.The Response interface of the Fetch API represents the response to a request.The Fetch API allows you to asynchronously request for a resource. Use the fetch() method to return a promise that resolves into a Response object. To get the actual data, you call one of the methods of the Response object e.g., text() or json() . These methods resolve into the actual data.The json() method of the Response interface takes a Response stream and reads it to completion. It returns a promise which resolves with the result of parsing the body text as JSON.

Please check the code below,

Preview of the output that you will get on running this code from your IDE.

Code:

In this solution we use the React library.

import React from "react";

class Api extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: null
    };
  }

  componentDidMount() {
    const that = this;
    const apiUrl =
      "https://us-east-1.aws.webhooks.mongodb-realm.com/api/client/v2.0/app/cv-xfzvw/service/cv/incoming_webhook/api?secret=cv";
    fetch(apiUrl)
      .then((res) => res.json())
      .then((json) => {
        that.setState({ data: JSON.stringify(json) });
      });
  }
  render() {
    return <div>my data: {this.state.data}</div>;
  }
}
export default Api;

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in App.js file(remove the earlier code from App.js).
Open the terminal from IDE.
npm start to run the file.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.

I found this code snippet by searching for 'Fetch API in Reactjs' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

The solution is created in VS Code 1.73.1 version.
The solution is tested on Nodejs 16.14.2 version.
react 18.2.0 version.

Using this solution, we are able to display the response from request using fetchAPI with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to display the response from request using fetchAPI.
