Azure pipeline to build angular JS app Bundle failing - npm ERR! missing script: D:\a\1\s/bundle.js

Question

So I am trying to build and publish an angular.js app up to azure blob storage. I have the project building and I now need to run the bundling task to create an output that I want to publish up to blob storage, but when I run the task I get : npm ERR! missing script: D:\a\1\s/bundle.js

The build step in question is an NPM task and has this YAML :

    - task: Npm@1
  displayName: 'npm bundle'
  inputs:
    command: custom
    workingDir: '$(System.DefaultWorkingDirectory)'
    verbose: false
    customCommand: 'run $(System.DefaultWorkingDirectory)/bundle.js'

Any idea how I do the bundling?

Here is the output from the task :

Answer 1

Ok so I changed the task type to a commandline task and just called node bundle.js :

steps:
- script: 'node bundle.js'
  displayName: 'Bundle JS'

Answer 2

Based on your latest comment, the bundle.js file is valid.

You could try the following steps to run js file with NPM Task.

1. Add the scripts parameters in Package.json file.

Example:

{
  "name": "webpackguide",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server",
    "bundle":"node bundle.js"
  },

....

2. In NPM task, you could directly call the bundle command:

Example:

- task: Npm@1
  displayName: 'npm custom'
  inputs:
    command: custom
    workingDir: '$(System.DefaultWorkingDirectory)'
    verbose: false
    customCommand: 'run bundle'
