Comprehensive guide for safely updating Angular projects with official tools and third-party library compatibility checks

Quick Navigation

Prerequisites Official Guide Library Compatibility

Before You Start

Create a backup of your project
Ensure all tests are passing
Update to the latest patch version
Review breaking changes documentation

Environment Setup

Update Node.js to LTS version
Update Angular CLI globally
Clear npm cache if needed

Important Warning

Always test your application thoroughly after each update step. Consider updating in a separate branch to avoid affecting your main development workflow.

Step-by-Step Process

Check Current Version

Verify your current Angular version and identify the target version

ng version

Run Update Command

Use the Angular CLI to update to the next major version

ng update @angular/core @angular/cli

Update Dependencies

Update other Angular packages and dependencies

ng update @angular/material @angular/cdk

Test and Fix

Run tests, fix any issues, and repeat for next version

ng test && ng build --prod

Best Practices

Update incrementally: Go one major version at a time

Read release notes: Always check breaking changes

Use TypeScript strict mode: Helps catch issues early

Update in CI/CD: Automate testing after updates

Pro Tip

Use the --dry-run flag to see what changes would be made without actually applying them.

Using Our Compatibility Matrix

Before updating Angular, check if your third-party libraries are compatible with the target Angular version using our comprehensive compatibility matrix.

Identify Dependencies

List all third-party libraries in your project

npm list --depth=0

Check Compatibility

Use our compatibility matrix to verify support

Open Compatibility Matrix

Plan Updates

Update incompatible libraries or find alternatives

Common Issues & Solutions

Incompatible Libraries

Check for newer versions or alternative libraries that support your target Angular version

Breaking Changes

Review migration guides for libraries that have breaking changes

Peer Dependencies

Ensure all peer dependencies are compatible with your Angular version

Library Update Strategy

Update libraries one at a time and test thoroughly after each update to isolate any issues that may arise.
