Node.js Version Upgrade for Angular Project: Compatibility

I'm currently working on an Angular 19 project with the following setup:

• 
  TypeScript 5.7
  
  
• 
  Node.js 20.11.1 (local development)
  
  
• 
  @types/node 20.11.25
  

Our backend team and CI/CD pipeline are planning to upgrade to Node.js 24. I'm trying to understand:

1. 
   Is it necessary to upgrade the frontend Angular project's Node.js version to match?
   
   • Since Angular runs in the browser, does the Node.js version matter beyond build tooling?
2. 
   If we do choose to upgrade, what's the recommended approach?
   
   • Are there specific compatibility concerns with Angular 19 and Node.js 24?
   • Should we update other dependencies like @types/node simultaneously?
3. 
   What are the potential risks of not upgrading while the CI/CD moves to Node.js 24?
   
   • Could this cause build inconsistencies between local and CI environments?
