ky

What is ky?

The ky npm package is a tiny and elegant HTTP client based on the browser's Fetch API. It provides a simpler and more powerful interface for making HTTP requests and handling responses. It is designed to be used with modern JavaScript, including support for async/await syntax.

What are ky's main functionalities?

GET requests

This feature allows you to perform GET requests to retrieve data from a specified resource. The example code demonstrates how to make a GET request and parse the response as JSON.

const json = await ky.get('https://jsonplaceholder.typicode.com/todos/1').json();

POST requests

This feature enables you to send POST requests to submit data to a server. The example code shows how to make a POST request with a JSON body and parse the response as JSON.

const json = await ky.post('https://jsonplaceholder.typicode.com/posts', { json: { title: 'foo', body: 'bar', userId: 1 } }).json();

Error handling

Ky provides simple error handling for failed HTTP requests. The example code demonstrates how to catch errors when a request fails, such as when the URL is invalid.

ky.get('https://jsonplaceholder.typicode.com/invalid-url').then(response => console.log(response)).catch(error => console.error(error));

Timeouts

Ky allows you to specify a timeout for the request. If the request takes longer than the specified time, it will be aborted. The example code sets a timeout of 5000 milliseconds.

ky.get('https://jsonplaceholder.typicode.com/todos', { timeout: 5000 }).then(response => console.log(response));

Hooks

Ky provides hooks that allow you to intercept requests and responses to perform actions or modify them. The example code logs a message before the request is made.

ky.get('https://jsonplaceholder.typicode.com/todos', { hooks: { beforeRequest: [request => { console.log('About to make a request', request); }] } }).then(response => console.log(response));

Other packages similar to ky

axios

Axios is a popular HTTP client for the browser and node.js. It supports promise-based API, interceptors, request cancellation, and more. Compared to ky, axios works in both the browser and Node.js environments, while ky is designed primarily for modern browsers.

got

Got is a powerful HTTP client for Node.js. It provides a lot of features like streams, retries, and advanced error handling. Unlike ky, which is built on the Fetch API, got is more suitable for server-side use and offers a wider range of options for Node.js developers.

node-fetch

node-fetch is a light-weight module that brings the browser's Fetch API to Node.js. It aims to provide a consistent API with the browser's Fetch, making it a closer alternative to ky for server-side development. However, ky offers additional features and a more fluent API on top of the basic Fetch functionality.

superagent

Superagent is a small progressive client-side HTTP request library. It has a flexible and expressive API that allows for chaining methods. Superagent is similar to ky in terms of client-side usage but does not rely on the Fetch API and has a different API design.
