What are the best strategies for implementing CI/CD pipelines for Node.js applications using Azure DevOps?

To set up CI/CD pipelines for your Node.js application in Azure DevOps, start by defining your build and deployment processes in a YAML file. Use Azure Pipelines to automate your build, test, and deployment phases. For continuous integration (CI), configure your pipeline to trigger a build and run tests on every code commit or pull request. On the other hand, for continuous deployment, create stages in your pipeline to deploy the application to different environments (like test, staging, and production) post-build.

Utilize Azure DevOps environments for managing and monitoring these deployments, and incorporate approval processes for deployments to higher environments. Remember to leverage Azure Repos for source control to integrate seamlessly with your pipelines.
