📦 Installation

npm install @nxtwebmasters/nxt-smart-logger
# or
yarn add @nxtwebmasters/nxt-smart-logger

🚀 Quick Start

import { ConsoleInterceptor } from "@nxtwebmasters/nxt-smart-logger";

const interceptor = new ConsoleInterceptor({
  batchSize: 10,
  flushInterval: 5000,
  contextProvider: () => ({
    userId: "USER123",
    sessionId: "SESSION456",
    appVersion: "1.0.0",
  }),
  serverLogger: async (logs) => {
    await fetch("https://yourserver.com/api/logs", {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify(logs),
    });
  },
});

const logger = interceptor.getLogger();
logger.info("User logged in");
logger.withTags(["auth"]).warn("Login attempt");
logger.withContext({ feature: "search" }).error("Search failed");
logger.withMeta({ region: "us-east-1" }).debug("Region-specific check");
logger.withAll({
  tags: ["api"],
  context: { feature: "checkout" },
  meta: { version: "2.1.0" },
}).error("API timeout");

interceptor.setContext({ userId: "ADMIN" });

🔌 Integration Examples — NXT Smart Logger

Here’s how to plug @nxtwebmasters/nxt-smart-logger into various environments:

⚛️ React Setup

// logger.ts
import { ConsoleInterceptor } from '@nxtwebmasters/nxt-smart-logger';

export const interceptor = new ConsoleInterceptor({
  contextProvider: () => ({
    userId: localStorage.getItem('userId'),
    sessionId: sessionStorage.getItem('sessId')
  }),
  serverLogger: async (logs) => {
    await fetch('/api/logs', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(logs),
    });
  }
});

export const logger = interceptor.getLogger();

// App.tsx
import { logger } from './logger';

function App() {
  useEffect(() => {
    logger.info('App mounted');
  }, []);
  return <h1>Welcome</h1>;
}

🧩 Vue Setup

// logger.ts
import { ConsoleInterceptor } from '@nxtwebmasters/nxt-smart-logger';

const interceptor = new ConsoleInterceptor({
  contextProvider: () => ({ userId: 'vue-user', role: 'admin' })
});

export const logger = interceptor.getLogger();

<script setup>
import { onMounted } from 'vue';
import { logger } from './logger';

onMounted(() => {
  logger.info('Vue component mounted');
});
</script>

🖥️ Node.js Setup (e.g., CLI apps or SSR)

import { ConsoleInterceptor } from '@nxtwebmasters/nxt-smart-logger';

const interceptor = new ConsoleInterceptor({
  enableGTM: false,
  enableServer: true,
  contextProvider: () => ({ env: 'node', pid: process.pid }),
  serverLogger: async (logs) => {
    console.log('Sending logs to API:', logs);
  }
});

const logger = interceptor.getLogger();
logger.info('CLI started');

Use the logger the same way across all frameworks:

logger.error('Something went wrong', { details: '...' })
logger.withTags(['startup']).info('App ready')

🌍 Works Anywhere

• React (hooks, SSR, client)
• Vue 2/3 (setup API or options API)
• Vanilla JS / CDN
• Node.js (CLI, workers, Express)
