camelCase Converter API: Complete Developer Guide

Need to convert text to camelCase format? This guide covers everything about camelCase conversion via API, including when to use camelCase, naming conventions, and implementation examples in multiple programming languages.

What is camelCase?

camelCase is a naming convention where the first letter of each word is capitalized except for the first word, with no spaces or separators. It's called camelCase because the capital letters resemble the humps of a camel.

Example: hello world example becomes helloWorldExample

When to Use camelCase

camelCase is commonly used in:

JavaScript

Variable names, function names, and object properties typically use camelCase.

Java

Methods and variables follow camelCase convention (classes use PascalCase).

JSON

Many APIs use camelCase for JSON property names.

Using the camelCase Converter API

TinyFn provides a simple endpoint to convert text to camelCase:

POST https://api.tinyfn.io/v1/text/camelcase
Headers: X-API-Key: your-api-key
Content-Type: application/json

{
  "text": "hello world example"
}

{
  "camelCase": "helloWorldExample",
  "original": "hello world example"
}

Parameters

Code Examples

JavaScript / Node.js

const response = await fetch(
  'https://api.tinyfn.io/v1/text/camelcase',
  {
    method: 'POST',
    headers: {
      'X-API-Key': 'your-api-key',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ text: 'user first name' })
  }
);
const { camelCase } = await response.json();
console.log(camelCase); // userFirstName

Python

import requests

response = requests.post(
    'https://api.tinyfn.io/v1/text/camelcase',
    headers={'X-API-Key': 'your-api-key'},
    json={'text': 'user first name'}
)
result = response.json()['camelCase']
print(result)  # userFirstName

cURL

curl -X POST "https://api.tinyfn.io/v1/text/camelcase" \
  -H "X-API-Key: your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"text": "user first name"}'

Common Use Cases

• Code Generation: Generate variable names from human-readable text
• API Responses: Convert database column names to JSON properties
• Data Transformation: Normalize data between different naming conventions
• Form Processing: Convert form field labels to field names
• Documentation: Generate consistent code examples

Best Practices

1. Be consistent: Use camelCase throughout your JavaScript/Java codebase
2. Handle acronyms: Decide how to handle abbreviations (e.g., XMLParser vs xmlParser)
3. Numbers: Be careful with numbers in names (e.g., item1Name)
4. Length: Keep names descriptive but not excessively long
