How to consume artifacts published by CI pipeline in CD pipeline - azure-devops

Question

I have CI and CD pipelines using Azure DevOps for a frontend angular project. Both are separate pipelines.
Here goes the YAML file for the CI pipeline which produces published artifact: output_final.zip. The below pipeline leverages Azure Pipelines for generating the published artifact.
# Node.js with Angular
# Build a Node.js project that uses Angular.
# Add steps that analyze code, save build artifacts, deploy, and more:
# https://learn.microsoft.com/azure/devops/pipelines/languages/javascript
trigger:
- integration
pool:
vmImage: ubuntu-latest
steps:
- task: NodeTool#0
inputs:
versionSpec: '14.x'
displayName: 'Install Node.js'
- powershell: |
$buildNumber="$(Build.BuildNumber)"
echo $buildNumber > src/version.txt
- script: |
npm install -g #angular/cli
npm install
ng build --prod
displayName: 'npm install and build'
- task: CopyFiles#2
displayName: 'Copy Files of UI'
inputs:
SourceFolder: 'dist/source'
TargetFolder: '$(Build.ArtifactStagingDirectory)/output'
OverWrite: true
- task: ArchiveFiles#2
displayName: 'Archive'
inputs:
rootFolderOrFile: '$(Build.ArtifactStagingDirectory)/output/'
includeRootFolder: false
archiveFile: '$(Build.ArtifactStagingDirectory)/output/output_final.zip'
- task: PublishBuildArtifacts#1
displayName: 'Publish Artifact'
inputs:
PathtoPublish: '$(Build.ArtifactStagingDirectory)/output/output_final.zip'
ArtifactName: drop
Now I have a separate CD pipeline which leverages self hosted private agent. In this CD pipeline, I want to consume artifacts published by the CI pipeline in the CD pipeline
Can anyone help me to know how to consume artifacts published by the CI pipeline and use it in the CD pipeline with some sample YAML example.

My suggestion would be to use the Publish Pipeline Artifact task to publish the CI artifact. Then, in your CD pipeline, use the Download Pipeline Artifact to consume it.
You can configure the download task to get the artifact from the current run or from a specific run. In your case, it sounds like you want a specific run since the CI pipeline is separate.
Here's an example of what the yaml tasks might look like:
#CI Task
- task: PublishPipelineArtifact#1
displayName: 'Publish pipeline Artifact'
inputs:
targetPath: '$(Pipeline.Workspace)'
artifact: '<Some Artifact Name>'
publishLocation: 'pipeline'
#CD Task example
- task: DownloadPipelineArtifact#2
inputs:
buildType: 'specific'
project: ''
definition: ''
specificBuildWithTriggering: true
buildVersionToDownload: 'latest'
targetPath: '$(Pipeline.Workspace)'
