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?

Make sure you run the Angular version with Node.js and Typescript based on the version compatibility page from Angular:

Angular.dev - Version Compability

Angular Node.js TypeScript RxJS
20.0.x ^20.19.0 || ^22.12.0 || ^24.0.0 >=5.8.0 <5.9.0 ^6.5.3 || ^7.4.0
19.2.x ^18.19.1 || ^20.11.1 || ^22.0.0 >=5.5.0 <5.9.0 ^6.5.3 || ^7.4.0

Node.js and Typescript are used during the build process.

In Node.js, the version compatibility does not mention support for version 24, But Node.js 24 can be used, since there is a chance that there might not be any build issues. It highly depends on If there are breaking changes and if these breaking changes are affecting your build.

The Typescript version must match what is specified (Major versions might contain breaking changes - 6.0.0) So make sure Typescript version matches what is there in the compatibility table.

Thank you for your answer, I understand. I have one more question. Is it okay if the node versions of the frontend and backend are different?
@suli as long as you have the newer version compared to the minimal required version in both scenarios its ok
