I have an Angular application, that is currently running without problems with Angular 13. Local build and deployment during DevOps YAML pipeline work well. We use an Npm@1 task to run "npm run build" (it's simply ng build) for our application here.
Now I've upgraded my application to Angular 17. On my local environment "npm run build" works fine without errors and the application is running. But during deployment with my DevOps pipeline I have problems. The build does either nothing (with Npm@1 task) or it seems to finish (with script task), but does not jump to the next pipeline step.
What did I try until now:
First I've used the same pipeline code like before with the Npm@1 task. Result: I see a black screen inside Devops and no output
- task: Npm@1
displayName: Build Angular Client
inputs:
command: custom
workingDir: 'my directory'
customCommand: 'run build'
At the moment I do my "npm run build" with a script task. I see the output (all generated bundles and so on), I see "Build at " like on my local machine. But the pipeline doesn't finish this script task and does not go to the next one. I also installed Angular CLI, Typescript and NodeJS before my build:
- task: UseNode@1
displayName: Install NodeJS 20.11.1
inputs:
version: '20.11.1'
- script: |
npm install -g @angular/[email protected]
displayName: Install Angular CLI 17.3.5
- script: |
npm install -g [email protected]
displayName: Install Typescript 5.4.5
- script: |
npm ci
displayName: Install Packages for App
workingDirectory: 'my directory'
- script: |
npm run build
env:
NODE_OPTIONS: '--max-old-space-size=4096'
displayName: Build App
workingDirectory: 'my directory'
When I run the generated cmd File on the agent server, the Angular Build runs without problems.
What I recognized: The order of the output from "npm run build" is different on my local machine and on DevOps. It seems to be a little bit mixed up on DevOps: Local machine:

I've also tried different versions of Angular CLI, Typescript, NodeJS with global install and without. And also we tried to set more space with NODE_OPTIONS.

Do you have any ideas what's going wrong here?
I found the problem: we use a custom-builder for our angular app ("builder": "@angular-builders/custom-webpack:browser") which works fine for angular 13. But has problems with angular 17 in our case. When I remove it and use the default builder ("@angular-devkit/build-angular:browser"), my "npm run build" process will not hang anymore. It works now on my local machine and in my Devops pipeline!
The next days there will be an update for this custom-webpack package, I hope, that this will perhaps fix the problem together with Angular 18. But for now I need to adapt my custom-webpack config or remove it and find another way to do some build steps in our project.
