@ethersproject/web
Advanced tools
@ethersproject/web is a part of the ethers.js library, which is a complete and compact library for interacting with the Ethereum blockchain and its ecosystem. This package specifically provides utilities for interacting with web resources, such as fetching data from URLs and handling HTTP requests.
Fetching Data from URLs
This feature allows you to fetch JSON data from a given URL. The `fetchJson` function is used to make an HTTP GET request to the specified URL and parse the response as JSON.
const { fetchJson } = require('@ethersproject/web');
async function fetchData(url) {
try {
const data = await fetchJson(url);
console.log(data);
} catch (error) {
console.error('Error fetching data:', error);
}
}
fetchData('https://api.example.com/data');
Handling HTTP Requests
This feature allows you to handle HTTP requests, including POST requests. The `fetchJson` function can be used to send data to a specified URL by setting the appropriate HTTP method and request body.
const { fetchJson } = require('@ethersproject/web');
async function postData(url, data) {
try {
const response = await fetchJson(url, { method: 'POST', body: JSON.stringify(data) });
console.log(response);
} catch (error) {
console.error('Error posting data:', error);
}
}
postData('https://api.example.com/data', { key: 'value' });
Axios is a popular promise-based HTTP client for the browser and Node.js. It provides a simple and easy-to-use API for making HTTP requests, handling responses, and managing errors. Compared to @ethersproject/web, Axios offers more features and flexibility for handling various types of HTTP requests and responses.
Node-fetch is a lightweight module that brings the `window.fetch` function to Node.js. It allows you to make HTTP requests in a similar way to the browser's fetch API. While @ethersproject/web focuses on Ethereum-related web interactions, node-fetch is a more general-purpose tool for making HTTP requests in Node.js environments.
Got is a human-friendly and powerful HTTP request library for Node.js. It supports promises, streams, retries, and many other features. Got is more feature-rich and flexible compared to @ethersproject/web, making it suitable for more complex HTTP request handling scenarios.
This sub-module is part of the ethers project.
It contains functions to abstract safely and responsibly connecting to the web, including exponential back-off.
