How to use pnpm on Azure Pipelines?

First, thank you for your question. Utilizing pnpm (a fast and efficient package manager) within the Azure DevOps environment can enhance the speed and efficiency of dependency installation, particularly for large-scale projects. The following steps outline how to configure and use pnpm on Azure Pipelines.

Step 1: Ensure Node.js is installed in the pipeline environment

Verify that Node.js is installed in the pipeline environment. This can be achieved by using the official Node.js tool installation task in the YAML configuration file. For example:

yaml
steps:
- task: NodeTool@0
  inputs:
    versionSpec: '12.x'
  displayName: 'Install Node.js'

Step 2: Install pnpm

After installing Node.js, the next step is to install pnpm within the pipeline. This can be done by running the following command:

yaml
steps:
- script: npm install -g pnpm
  displayName: 'Install pnpm'

Step 3: Use pnpm to install dependencies

Once pnpm is installed, you can proceed to install the project dependencies using pnpm.

yaml
steps:
- script: pnpm install
  displayName: 'Install dependencies with pnpm'

Step 4: Build and test the project

After installing the dependencies, you can continue with building and testing the project. This can be accomplished by executing project-specific build scripts or frameworks. For instance, if using Angular:

yaml
steps:
- script: pnpm run build
  displayName: 'Build the project'

- script: pnpm run test
  displayName: 'Run tests'

Example: Complete YAML Configuration for Integrating pnpm into Azure Pipelines

Combining the above steps, here is a complete example demonstrating how to integrate pnpm into an Azure Pipeline:

yaml
trigger:
- main

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: NodeTool@0
  inputs:
    versionSpec: '12.x'
  displayName: 'Install Node.js'

- script: npm install -g pnpm
  displayName: 'Install pnpm'

- script: pnpm install
  displayName: 'Install dependencies with pnpm'

- script: pnpm run build
  displayName: 'Build the project'

- script: pnpm run test
  displayName: 'Run tests'

Conclusion

By following these steps, you can successfully use pnpm within Azure DevOps pipelines to manage and install dependencies for Node.js projects. This not only speeds up the installation process but also enhances project stability and maintainability through pnpm's strict dependency management.
