SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires jq, and includes scripts (resource) components.

What problem does it solve?

This guide addresses the risk and complexity of upgrading Nx libraries to be dual-compatible with Angular 15 and 16, enabling smoother migrations in monorepos.

Core Features & Use Cases

Incremental upgrade strategy: upgrade libraries one at a time while applications run on Angular 15.
Widened peerDependencies: prepare libs to declare support for both Angular 15 and 16.
Pre-flight audits: verify compatibility and identify blockers before migration, using the included script.
Practical guidance: provide concrete steps, commands, and checks for common blockers in a large codebase.

Quick Start

Start by running the audit script against your library to identify Angular 16 readiness and plan the incremental upgrade process.

FAQPage Schema

How do I upgrade an Nx library to Angular 16 while my monorepo apps stay on version 15?▼

To upgrade an Nx library to Angular 16 while apps stay on 15, widen peerDependencies to support both versions and migrate libraries incrementally one at a time. This dual-compatibility approach enables gradual migration without application downtime.

What is a pre-flight audit script for Angular 16 migration and how does it work?▼

A pre-flight audit script for Angular 16 migration verifies library compatibility and identifies blockers before you start upgrading. Running it against your library checks readiness and helps plan the incremental upgrade process across monorepo versions.

Can I use this incremental Angular upgrade strategy in a large Nx monorepo?▼

Yes, this incremental Angular upgrade strategy is designed for Nx-based libraries in monorepos. It provides concrete steps, commands, and checks to handle common blockers encountered when upgrading large codebases to support dual Angular 15 and 16 compatibility.

Do I need jq to run the Angular 16 dual compatibility audit?▼

Yes, you need jq installed to run the Angular 16 dual compatibility audit script. The dependency is required to parse and verify compatibility data when identifying migration blockers in your Nx library codebase.

What are the limitations of upgrading Angular libraries one at a time in a monorepo?▼

Upgrading Angular libraries one at a time requires widening peerDependencies and careful iterative validation across both versions. Limitations include managing common blockers in large codebases and ensuring applications remain stable on Angular 15 throughout the gradual migration process.
