Is it possible to implement a Node.js application within an Azure DevOps deployment process?

Recently, I embarked on my journey to learn Node.js and Azure DevOps. To get a better grasp of how things function in Azure DevOps, I attempted to execute a basic Node.js example. Unfortunately, I hit a roadblock when an error surfaced, leaving me unsure about the next steps to take. The source code I have imported from Github (File1.js) looks like this:

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

server.listen(port, hostname, () => {
  console.log('Server running at http://${hostname}:${port}/');
});

In my azure-pipelines.yml file, you will find the following snippet:

# Node.js
# Build a general Node.js project with npm.
# Add steps that analyze code, save build artifacts, deploy, and more:
# https://learn.microsoft.com/azure/devops/pipelines/languages/javascript

pool:
  vmImage: 'Ubuntu 16.04'

steps:
- task: NodeTool@0
  inputs:
    versionSpec: '11.x'
  displayName: 'Install Node.js'

- task: Npm@1
  displayName: 'npm install'
  inputs:
    command: install

- script: npm compile 'File1.js'

Though I understand that the final line in the .yml file is causing an error, I am clueless about how to establish the connection with the .js file for execution. When I remove that problematic line, everything runs smoothly, except... the file remains unexecuted. Any guidance or solutions to resolve this predicament would be immensely valued! Thank you in advance!

While I may not be well-versed in nodes, I'm here to help you with your workflow. Here's a general overview of how things usually go:

  1. Firstly, you commit your code.
  2. Next, the build process initiates and compiles/tests your code, then packages it into an archive or package.
  3. Finally, the release phase kicks in to deploy the build results to the server for execution and client access.

If you need guidance on setting up a pipeline for nodejs, I have a sample one below.

pool:
  vmImage: 'Ubuntu 16.04'

steps:
- task: NodeTool@0
  inputs:
    versionSpec: '8.x'
  displayName: 'Install Node.js'

- script: |
    npm install
    npm run build
  displayName: 'npm install and build'

- script: |
    zip -r result.zip . -x .git/**\* > /dev/null
  displayName: 'package results'

- task: PublishBuildArtifacts@1
  inputs:
    pathtoPublish: '$(Build.SourcesDirectory)/result.zip' 
    artifactName: 'drop' 
  displayName: 'upload artifacts'
