JavaScript client for the DevKits REST API — JSON formatting, Base64, JWT decoding, UUID generation, hashing, regex testing, Markdown conversion, text diff, and cron parsing.

Installation

npm install devkits-client

Quick Start

const { createClient } = require('devkits-client');

const devkits = createClient(); // free tier: 100 req/day

// Format JSON
const result = await devkits.json.format('{"a":1,"b":2}');
console.log(result.formatted);
// {
//   "a": 1,
//   "b": 2
// }

// Generate UUID
const { uuids } = await devkits.uuid.generate();
console.log(uuids[0]); // e.g. "550e8400-e29b-41d4-a716-446655440000"

// Encode Base64
const { encoded } = await devkits.base64.encode('Hello, World!');
console.log(encoded); // "SGVsbG8sIFdvcmxkIQ=="

// Decode JWT
const jwt = await devkits.jwt.decode('eyJhbGciOiJIUzI1NiJ9...');
console.log(jwt.payload);

// Hash text
const { hash } = await devkits.hash.generate('password', 'sha256');
console.log(hash);

// Test regex
const { matches } = await devkits.regex.test('\\d+', 'foo 123 bar 456');
console.log(matches); // ["123", "456"]

// Parse cron
const { description } = await devkits.cron.parse('0 9 * * 1-5');
console.log(description); // "At 09:00 AM, Monday through Friday"
