Installation - Law4Devs

Requirements

Node.js 18+ (uses the native fetch API — no polyfill needed)
npm, yarn, or pnpm

The SDK uses the global fetch available in Node 18 and all modern browsers. No additional HTTP dependencies are required.

Install

npm install law4devs

yarn add law4devs

pnpm add law4devs

First Call

import { Law4DevsClient } from 'law4devs';

const client = new Law4DevsClient({
  apiKey: process.env.LAW4DEVS_API_KEY!,
});

const page = await client.frameworks.list();
console.log(`Found ${page.meta.total} EU regulatory frameworks`);

for (const fw of page.data) {
  console.log(`${fw.shortName}: ${fw.name}`);
}

Constructor Options

const client = new Law4DevsClient({
  apiKey: process.env.LAW4DEVS_API_KEY!,
  baseUrl: 'https://api.law4devs.eu/v1',  // default
  timeout: 30_000,   // ms before request is aborted (default: 30000)
  maxRetries: 3,     // retries on 429/5xx (default: 3)
});

Option	Type	Default	Description
`apiKey`	`string`	—	Required. Your API key
`baseUrl`	`string`	Production URL	Override for dev environment
`timeout`	`number`	`30000`	Request timeout in milliseconds
`maxRetries`	`number`	`3`	Retries on 429/5xx

Never hardcode your API key in source code or commit it to version control. Always use environment variables.

Retries use exponential backoff. Timeouts are enforced via AbortController and work in both Node.js and browsers.
