Upgrading Bleu.js

This guide will help you upgrade Bleu.js to the latest version safely and efficiently. Follow these steps to ensure a smooth upgrade process.

Before You Start

Backup your current configuration and data
Review the changelog for breaking changes
Test the upgrade in a development environment first
Ensure you have sufficient disk space and system resources
Schedule downtime if upgrading production systems

Upgrade Process

Step 1: Check Current Version

First, check your current Bleu.js version:

npm list bleujs

Step 2: Update Dependencies

Update Bleu.js to the latest version:

npm install bleujs@latest

Or install a specific version: npm install [email protected]

Step 3: Review Breaking Changes

Check for any breaking changes that might affect your application:

Review API response format changes
Check for deprecated methods or properties
Update configuration files if needed
Test authentication flows

Step 4: Update Your Code

Update your application code to use the new API:

// Old way (deprecated)
const bleu = require('bleujs');
bleu.generate('Hello world');

// New way
const { BleuJS } = require('bleujs');
const bleu = new BleuJS(apiKey);
const response = await bleu.generate('Hello world');

Step 5: Test Thoroughly

Test your application to ensure everything works correctly:

Run your test suite
Test all API integrations
Verify authentication and authorization
Check error handling
Test performance and memory usage

Step 6: Deploy

Deploy your updated application:

Deploy to staging environment first
Monitor for any issues
Deploy to production during low-traffic periods
Have a rollback plan ready
