Introduction to Firestore Logger

Firestore Logger is a versatile and powerful logging library designed for Google Cloud Firestore. It allows developers to efficiently log and manage data within their Firestore database, offering a seamless integration and numerous APIs to facilitate robust logging practices.

Getting Started

Before you can use Firestore Logger, you need to install it in your project:

npm install firestore-logger

Core APIs

Firestore Logger provides a wealth of APIs to interact with your Firestore database.

1. Initialize Logger

 const FirestoreLogger = require('firestore-logger'); const logger = new FirestoreLogger({
  projectId: 'your-project-id',
  collection: 'logs',
}); 

2. Log Messages

 logger.log('info', 'This is an info message'); logger.log('warn', 'This is a warning message'); logger.log('error', 'This is an error message'); 

3. Log with Metadata

 logger.log('info', 'User signed in', { userId: '12345', region: 'US' }); 

4. Get Logs

 async function getLogs() {
  const logs = await logger.getLogs({ level: 'info', limit: 10 });
  console.log(logs);
} getLogs(); 

5. Delete Logs

 async function deleteLogs() {
  await logger.deleteLogs({ level: 'info', olderThan: '2023-01-01' });
  console.log('Old logs deleted');
} deleteLogs(); 

App Example

Here is an example of a simple app that uses Firestore Logger to log user activities:

 const express = require('express'); const FirestoreLogger = require('firestore-logger'); const logger = new FirestoreLogger({ projectId: 'your-project-id', collection: 'logs' });
const app = express();
app.use(express.json());
app.post('/login', (req, res) => {
  logger.log('info', 'User logged in', { userId: req.body.userId });
  res.send('Login logged');
});
app.get('/logs', async (req, res) => {
  const logs = await logger.getLogs({ limit: 50 });
  res.json(logs);
});
const PORT = process.env.PORT || 3000; app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
}); 

By following these approaches, you can efficiently manage and log activities within your Firestore database, effectively enhancing your application’s performance and debugging capabilities.
