2. Getting Started

This guide will help you get started with the Amadeus Protocol SDK in your project. We'll cover installation, basic setup, and your first queries and transactions.

Installation

Package Installation

Install the SDK using your preferred package manager:

# npm
npm install @amadeus-protocol/sdk

# yarn
yarn add @amadeus-protocol/sdk

# pnpm
pnpm add @amadeus-protocol/sdk

# bun
bun add @amadeus-protocol/sdk

Verify Installation

After installation, verify the package is installed correctly:

# Check package version
npm list @amadeus-protocol/sdk

# Or check in your code
import { AmadeusSDK } from '@amadeus-protocol/sdk'
console.log('SDK Version:', AmadeusSDK.getVersion())

Requirements

Node.js

The SDK requires Node.js version 20.0.0 or higher.

Check your Node.js version:

node --version

If you need to update Node.js, visit nodejs.org.

TypeScript (Optional)

TypeScript is optional but highly recommended. The SDK includes complete type definitions.

Install TypeScript:

npm install -D typescript @types/node

Browser Support

The SDK works in modern browsers that support:

• ES2020 features

• fetch API (or polyfill)

• Web Crypto API (for encryption features)

Basic Setup

Import the SDK

import { AmadeusSDK } from '@amadeus-protocol/sdk'

Initialize the SDK

// Using default node URL
const sdk = new AmadeusSDK()

// Or specify a custom node URL
const sdk = new AmadeusSDK({
	baseUrl: 'https://nodes.amadeus.bot/api',
	timeout: 30000 // Optional: request timeout in milliseconds
})

Your First Query

Let's start with a simple chain query:

import { AmadeusSDK } from '@amadeus-protocol/sdk'

const sdk = new AmadeusSDK()

// Get the current chain tip
const tip = await sdk.chain.getTip()
console.log('Current height:', tip.entry.height)
console.log('Chain hash:', tip.entry.hash)

Your First Transaction

Here's how to build and submit a simple token transfer:

import { AmadeusSDK, TransactionBuilder, generateKeypair } from '@amadeus-protocol/sdk'

const sdk = new AmadeusSDK()

// Generate a keypair (or use an existing one)
const keypair = generateKeypair()
console.log('Public Key (Address):', keypair.publicKey)
console.log('Private Key (Seed):', keypair.privateKey) // Keep this secret!

// Create a transaction builder
const builder = new TransactionBuilder(keypair.privateKey)

// Build and sign a transfer transaction
const { txHash, txPacked } = builder.transfer({
	recipient: '5Kd3N...', // Recipient's address
	amount: 10.5, // Amount in AMA
	symbol: 'AMA' // Token symbol
})

console.log('Transaction hash:', txHash)

// Submit the transaction
const result = await sdk.transaction.submit(txPacked)
if (result.error === 'ok') {
	console.log('Transaction submitted successfully!')
} else {
	console.error('Transaction error:', result.error)
}

TypeScript Configuration

If using TypeScript, ensure your tsconfig.json includes:

{
	"compilerOptions": {
		"target": "ES2020",
		"module": "ESNext",
		"lib": ["ES2020"],
		"moduleResolution": "node",
		"esModuleInterop": true,
		"strict": true
	}
}

Common Imports

Here are the most commonly used imports:

// Main SDK class
import { AmadeusSDK } from '@amadeus-protocol/sdk'

// Transaction building
import { TransactionBuilder } from '@amadeus-protocol/sdk'

// Key generation
import { generateKeypair, derivePublicKeyFromSeedBase58 } from '@amadeus-protocol/sdk'

// Encoding utilities
import { toBase58, fromBase58 } from '@amadeus-protocol/sdk'

// Amount conversions
import { toAtomicAma, fromAtomicAma } from '@amadeus-protocol/sdk'

// Encryption
import { encryptWithPassword, decryptWithPassword } from '@amadeus-protocol/sdk'

Troubleshooting Installation

"Module not found" Error

Problem: Cannot find module '@amadeus-protocol/sdk'

Solutions:

1. Ensure the package is installed:

   npm install @amadeus-protocol/sdk

2. Check your package.json:

   {
   	"dependencies": {
   		"@amadeus-protocol/sdk": "^1.0.0"
   	}
   }

3. Clear cache and reinstall:

   npm cache clean --force
   rm -rf node_modules package-lock.json
   npm install

TypeScript Errors

Problem: Type errors when importing

Solutions:

1. Ensure TypeScript is installed:

   npm install -D typescript

2. Check tsconfig.json:

   {
   	"compilerOptions": {
   		"moduleResolution": "node",
   		"esModuleInterop": true
   	}
   }

3. Restart your TypeScript server/IDE

Node.js Version Issues

Problem: Errors related to Node.js version

Solutions:

1. Check Node.js version:

   node --version

2. Update to Node.js 20+ if needed

3. Use a version manager like nvm:

   nvm install 20
   nvm use 20
