Add company object, carrier typing, threat intelligence fields (is_icloud_relay, is_datacenter, blocklists), and language code to the TypeScript interface. Add company to valid fields list while keeping organisation for backwards compatibility. Bump to 2.3.0. https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
Add optional baseUrl constructor parameter so users can target the EU endpoint (eu-api.ipdata.co) or any custom URL. Export EU_BASE_URL constant. Update README with EU endpoint docs and response fields reference for company, carrier, and threat objects. https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
Major upgrades: - axios: ^0.21.1 → ^1.13.5 (fixes known CVEs) - lru-cache: ^5.1.1 → ^11.2.6 (maxAge→ttl, LRUCache named export) - typescript: ^4.6.3 → ^5.9.3 (target es5→es2015) - tslib: ^1.10.0 → ^2.8.1 - prettier: ^1.18.2 → ^3.8.1 - @typescript-eslint/*: ^2.6.1 → ^8.56.0 - eslint: ^6.5.1 → ^8.57.0 - jest: ^24.9.0 → ^29.7.0, ts-jest: ^24.1.0 → ^29.4.6 Held back ESM-only packages (is-ip, url-join) and eslint 9+ (flat config migration out of scope). Updated CacheConfig interface (maxAge→ttl), eslint config (removed deprecated prettier/@typescript-eslint), tsconfig (es2015 target, explicit moduleResolution), and README. https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
BREAKING CHANGE: Requires Node.js >= 18 (for native fetch). CacheConfig.maxAge renamed to CacheConfig.ttl (from lru-cache v11). Version bumped to 3.0.0. - Replace axios with native fetch (zero-dep HTTP) - Replace lodash/isString and lodash/isArray with typeof/Array.isArray - Replace is-ip with Node built-in net.isIP() - Replace url-join with URL constructor - Mock all HTTP calls in tests (no API key required for CI) - Remove dotenv-cli (tests no longer need env vars) - Runtime deps reduced from 6 to 2 (lru-cache, tslib) https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
- Fix trailing whitespace in test descriptions - Use toBe() instead of toEqual() for primitive comparisons - Add parentheses to single-param arrow functions - Format long object literals across multiple lines - Use toBeDefined() instead of not.toBeUndefined() https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
- Replace `any` types with proper types in ipdata.ts (unknown, LookupResponse[]) - Fix no-use-before-define by moving keyBy() above its usage in tests - Replace for...of with Array.reduce to satisfy no-restricted-syntax rule - Type mockFetchResponse parameter as unknown instead of any - Update README badge URL to match package.json repository (thomasconner) - Add missing organisation field to README response fields list https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
Tests use mocked fetch and don't make real API calls. https://claude.ai/code/session_01UabaLo3R3sXovyxaZo2yCF
