Convert curl Commands to JavaScript: fetch vs axios

Converting curl commands to JavaScript is a common task when working with APIs. Whether you prefer fetch or axios, our curl converter makes it easy.

Why Convert curl to JavaScript?

• API documentation often provides curl examples
• Testing API endpoints quickly
• Integrating APIs into web applications
• Understanding request structure

Using Our curl Converter

1. Paste your curl command into the input field
2. Choose your preferred output format (fetch or axios)
3. Copy the generated code
4. Use it directly in your project

fetch vs axios: Which to Choose?

fetch (Native Browser API)

Pros:

• Built into modern browsers - no dependencies
• Promise-based API
• Lightweight

Cons:

• Requires manual JSON parsing
• No automatic request/response interceptors
• Less convenient error handling

axios (Popular Library)

Pros:

• Automatic JSON parsing
• Request/response interceptors
• Better error handling
• Request cancellation support

Cons:

• Requires installation (adds to bundle size)
• Additional dependency to manage

Example Conversion

curl command:

curl -X POST https://api.example.com/users \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer token123" \
  -d '{"name": "John", "email": "john@example.com"}'

fetch equivalent:

fetch('https://api.example.com/users', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer token123'
  },
  body: JSON.stringify({
    name: 'John',
    email: 'john@example.com'
  })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

Best Practices

• Always handle errors properly
• Use async/await for cleaner code
• Validate responses before using data
• Set appropriate timeout values
• Handle different HTTP status codes
