About JavaScript HTTP Requests
The Fetch API provides a modern, promise-based interface for making HTTP requests in JavaScript. It's built into all modern browsers and available in Node.js 18+. The API is designed to be simple yet powerful, supporting all HTTP methods, headers, and body types while providing a clean, chainable promise-based syntax.
Key Features
- Native browser support (no library needed)
- Promise-based for easy async/await usage
- Streaming response bodies
- Request and Response objects for flexibility
- CORS support built-in
- Available in Node.js 18+ natively
- AbortController for request cancellation
Frequently Asked Questions
How do I convert a curl command to JavaScript?
Paste your curl command in the input box and click "Convert". The tool generates JavaScript code using the modern fetch API that works in browsers and Node.js.
Does the JavaScript code work in Node.js?
Yes! The fetch API is natively available in Node.js 18 and later. For older versions, you can use the node-fetch package.
How do I handle the response in JavaScript?
The generated code uses .then() chains to process the response. The response.json() method parses JSON responses. You can also use async/await syntax for cleaner code.
Can I use axios instead of fetch?
Currently, the tool generates fetch API code. Axios is a popular alternative that provides additional features like automatic transforms and interceptors.
How do I handle errors in fetch requests?
The generated code includes a .catch() handler for network errors. Note that fetch only rejects on network failures, not HTTP errors (4xx, 5xx). Check response.ok for HTTP errors.
