YARNRC Authenticate

Minimal custom Azure DevOps task inspired by NpmAuthenticateV0, but targeting .yarnrc.yml.

What it does

• Reads a .yarnrc.yml file from workingFile.
• Reads service connection credentials from customEndpoint (comma-separated IDs).
• Matches service-connection registry URLs to npmScopes.*.npmRegistryServer.
• Writes auth into:
  • npmScopes[scope].npmAuthToken or npmAuthIdent
  • npmRegistries[registry].npmAuthToken or npmAuthIdent
• Sets npmAlwaysAuth: true for matched entries.

Structure

• Tasks/YarnrcAuthenticate/task.json
• Tasks/YarnrcAuthenticate/src/yarnrcauth.ts
• Tasks/YarnrcAuthenticate/dist/yarnrcauth.js (generated)
• package.json
• tsconfig.json

Install deps

yarn install
yarn build

Use in pipeline (after packaging and publishing the custom task)

- task: YarnrcAuthenticate@1
  inputs:
    workingFile: $(Build.SourcesDirectory)/.yarnrc.yml
    customEndpoint: your-service-connection-id

Notes

• workingFile must be .yarnrc.yml or .yarnrc.yaml.
• If no customEndpoint is provided, task exits with warning and no file changes.
