Package description
The isomorphic-fetch npm package is a library that enables the use of the Fetch API in both server-side (Node.js) and client-side (browser) environments. It provides a consistent interface for making HTTP requests, allowing developers to write universal code that works across different platforms.
Making HTTP GET requests
This code sample demonstrates how to make a simple HTTP GET request to retrieve data from a specified URL and then process the JSON response.
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));Making HTTP POST requests
This code sample shows how to make an HTTP POST request to send JSON data to a server and then handle the JSON response.
fetch('https://api.example.com/data', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({ key: 'value' })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));Handling HTTP errors
This code sample illustrates how to handle errors in HTTP requests by checking the response status and throwing an error if the response is not successful.
fetch('https://api.example.com/data')
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('Error:', error));Axios is a popular HTTP client for the browser and Node.js. It provides a promise-based API and has a similar feature set to isomorphic-fetch, including interceptors, automatic transforms for JSON data, and cancellation of requests. Axios also provides more detailed configuration options for requests compared to isomorphic-fetch.
Node-fetch is a light-weight module that brings the Fetch API to Node.js. It is similar to isomorphic-fetch but is specifically designed for Node.js environments. Unlike isomorphic-fetch, node-fetch does not provide a polyfill for the browser environment.
Whatwg-fetch is a polyfill for the Fetch API for browsers that do not support it natively. It is similar to isomorphic-fetch in that it allows the use of the Fetch API in the browser, but it does not provide support for Node.js environments.
Cross-fetch is another library that provides a polyfill for the Fetch API for both Node.js and browser environments. It is similar to isomorphic-fetch in its universal approach, but it may have different implementation details or additional features.
Readme
Fetch for node and Browserify. Built on top of GitHub's WHATWG Fetch polyfill.
fetch as a global so that its API is consistent between client and server.npm install --save isomorphic-fetch es6-promise
bower install --save isomorphic-fetch es6-promise
require('es6-promise').polyfill();
require('isomorphic-fetch');
fetch('//offline-news-api.herokuapp.com/stories')
.then(function(response) {
if (response.status >= 400) {
throw new Error("Bad response from server");
}
return response.json();
})
.then(function(stories) {
console.log(stories);
});
