Code Snippets

Generate Keypair

import nacl from 'tweetnacl';

const keypair = nacl.sign.keyPair();
const publicKey = Buffer.from(keypair.publicKey).toString('hex');
const secretKey = keypair.secretKey;

Canonical JSON

function canonicalJson(obj) {
  if (obj === null) return 'null';
  if (Array.isArray(obj)) {
    return '[' + obj.map(canonicalJson).join(',') + ']';
  }
  if (typeof obj === 'object') {
    const keys = Object.keys(obj).sort();
    return '{' + keys.map(k => `"${k}":${canonicalJson(obj[k])}`).join(',') + '}';
  }
  return JSON.stringify(obj);
}

Sign Message

function sign(message, secretKey) {
  const messageBytes = Buffer.from(canonicalJson(message));
  const signatureBytes = nacl.sign.detached(messageBytes, secretKey);
  return Buffer.from(signatureBytes).toString('hex');
}

Make Authenticated Request

async function authenticatedFetch(url, options, token) {
  return fetch(url, {
    ...options,
    headers: {
      ...options.headers,
      'Authorization': `Bearer ${token}`,
      'Content-Type': 'application/json'
    }
  });
}
