Overview

Easily convert your raw cURL commands into clean, production-ready JavaScript code snippets using the Axios HTTP client. This tool parses headers, request methods, query parameters, and request bodies, generating a structured Axios configuration object suitable for Node.js or browser environments.

When to Use

  • When migrating API requests tested in the terminal or Postman into a JavaScript or Node.js application.
  • When you need to quickly generate Axios boilerplate code with complex headers, authentication tokens, and payload structures.
  • When debugging API integrations and verifying how a specific cURL request translates into an Axios configuration object.

How It Works

  • Paste your raw cURL command into the input text area.
  • Toggle options to pretty-print the request body or include explanatory comments in the generated code.
  • Copy the instantly generated JavaScript Axios code snippet containing the URL, method, headers, and data payload.

Use Cases

Converting a cURL command from API documentation into a reusable Axios request function.
Generating Axios code for POST requests containing complex JSON payloads and custom authorization headers.
Translating multi-line cURL commands with cookies and custom user-agents into clean JavaScript.

Examples

1. Converting a POST Request with JSON Payload

Frontend Developer
Background
A developer is integrating a third-party user registration API. The API documentation only provides a cURL example for creating a user.
Problem
Manually translating the cURL headers and JSON body into an Axios POST request is tedious and prone to syntax errors.
How to Use
Paste the cURL command containing the -d JSON payload into the input field, enable 'Pretty-print body', and copy the generated Axios code.
Example Config
curl -X POST https://api.example.com/v1/users -H "Content-Type: application/json" -d '{"username":"dev_user","email":"[email protected]"}'
Outcome
An Axios code snippet is generated with the URL, method set to 'post', headers object, and a formatted data object.

2. Translating an Authenticated GET Request

Backend Engineer
Background
An engineer needs to fetch secure data from an external microservice using a Bearer token tested in the terminal.
Problem
The engineer needs to quickly write a Node.js script using Axios that includes the Authorization header.
How to Use
Paste the cURL command containing the -H "Authorization: Bearer token" flag into the tool.
Example Config
curl https://api.example.com/data -H "Authorization: Bearer secret_token_123"
Outcome
An Axios GET request snippet is produced, containing the Authorization header mapped correctly inside the headers configuration.

FAQ

Does this tool support all cURL flags?

It supports the most common flags for HTTP requests, including method specifications (-X), headers (-H), and data payloads (-d, --data, --data-raw).

Can I use the generated Axios code in both Node.js and the browser?

Yes, Axios is isomorphic, so the generated configuration object and request structure work in both environments.

How does the tool handle JSON payloads?

It parses the JSON string from the cURL data flag and formats it as a native JavaScript object inside the Axios data property.

Is my sensitive API data sent to a server?

No, the conversion is performed entirely in your browser, ensuring your API keys, tokens, and payloads remain secure.

What does the 'Pretty-print body' option do?

It formats nested JSON payloads in the request data with clean indentation and line breaks for better readability.
