Introduction to zt-express-logger

zt-express-logger is a powerful and easy-to-use logging library designed specifically for Express.js applications. It provides extensive logging capabilities and helps developers to maintain cleaner, more efficient code.

Key Features

• Simple and quick setup
• Highly customizable logging levels
• Middleware support for Express.js
• Support for various output formats (JSON, plaintext, etc.)
• Ability to log to different targets (console, files, remote servers)

API Examples

Below are examples of how to use the zt-express-logger APIs in your application.

1. Basic Setup

 // Import the logger const express = require('express'); const ztExpressLogger = require('zt-express-logger');
// Create an Express app const app = express();
// Set up the logger middleware app.use(ztExpressLogger()); 

2. Custom Logging Levels

 // Define custom logging levels const logger = ztExpressLogger({
  levels: {
    error: 0,
    warn: 1,
    info: 2,
    verbose: 3,
    debug: 4,
  }
});
app.use(logger); 

3. Log to File

 const logger = ztExpressLogger({
  transports: [
    new ztExpressLogger.transports.Console(),
    new ztExpressLogger.transports.File({ filename: 'app.log' }),
  ]
});
app.use(logger); 

4. JSON Logging

 const logger = ztExpressLogger({
  format: ztExpressLogger.format.json(),
  transports: [
    new ztExpressLogger.transports.Console(),
  ]
});
app.use(logger); 

5. Log to Remote Server

 const logger = ztExpressLogger({
  transports: [
    new ztExpressLogger.transports.Console(),
    new ztExpressLogger.transports.Http({
      host: 'remote-logging-server.com',
      path: '/log'
    }),
  ]
});
app.use(logger); 

Application Example

Below is a complete example of an Express.js application using zt-express-logger for comprehensive logging.

 const express = require('express'); const ztExpressLogger = require('zt-express-logger');
const app = express();
const logger = ztExpressLogger({
  levels: {
    error: 0,
    warn: 1,
    info: 2,
    verbose: 3,
    debug: 4,
  },
  transports: [
    new ztExpressLogger.transports.Console(),
    new ztExpressLogger.transports.File({ filename: 'app.log' }),
    new ztExpressLogger.transports.Http({
      host: 'remote-logging-server.com',
      path: '/log'
    }),
  ]
});
app.use(logger);
app.get('/', (req, res) => {
  res.send('Hello World');
  logger.info('Handled / request');
});
app.listen(3000, () => {
  console.log('Server is running on port 3000');
}); 

By integrating zt-express-logger, you can enhance the logging mechanism of your Express.js applications significantly and ensure better monitoring and debugging experience.
