Add registry-url and registry-token for authenticating the action's automatic dependency install against a private registry. Project configuration continues to select the default or scoped registry; these inputs supply authentication only.

- uses: pnpm/setup@v2
  with:
    registry-url: https://npm.pkg.github.com/
    registry-token: ${{ secrets.PACKAGES_TOKEN }}

For GitHub Packages, the project's .npmrc should already route the package scope, for example @myorg:registry=https://npm.pkg.github.com/.

Both inputs are required together. URLs must use HTTPS, with HTTP allowed only for local loopback registries. Credentials, query strings, fragments, and equals signs in registry URLs are rejected.

Authentication is supplied through a registry-scoped environment variable only to the install child process. No pnpm config set, persistent credential file, or token-bearing command argument is used. The raw token input is removed from inherited environments and omitted from post-action state, and the token is registered for log masking. Install subprocesses necessarily have access to the scoped credential.

This feature requires pnpm 11.6.0 or newer, when URL-scoped environment authentication became available. Older versions fail with a clear message. With install: false, authentication is not configured; subsequent install or publish steps need their own credentials.

Validation: 70 unit tests pass, covering input validation, registry key normalization, child environments, install failures/signals, and older pnpm. A real local-registry integration test verifies authenticated metadata and tarball requests and unchanged existing configuration. Added Linux/Windows CI coverage with pnpm 11.6.0 and 12.5.1. TypeScript, YAML validation, and bundle checks pass.

Rebased onto current main, retaining the cache and automatic Node-version-file changes, and regenerated the bundle.

Partially addresses #13. Scoped registry routing, NODE_AUTH_TOKEN fallback, and authentication for later publishing steps remain outside this PR's scope.

📝 Walkthrough

Walkthrough

The action adds private registry inputs, validates registry credentials and URLs, masks tokens, and passes authentication only to the pnpm install subprocess. It adds unit, integration, workflow, and README coverage.

Changes

Private registry authentication

Layer / File(s) Summary
Registry input contract
action.yml, src/inputs/index.ts, src/inputs/index.test.mjs
The action defines registry-url and registry-token. Validation requires both inputs, restricts registry URLs, rejects unsafe token characters, and stores a RegistryConfig.
Secret lifecycle handling
src/index.ts
The action masks the token, removes INPUT_REGISTRY-TOKEN, and excludes registry data from saved post-step state.
pnpm registry installation
src/pnpm-install/registry.ts, src/pnpm-install/index.ts, src/pnpm-install/*test.mjs
The install path requires pnpm 11.6.0 or newer for registry authentication. It creates a URL-scoped pnpm token environment variable and passes it only to the install subprocess without using a shell.
Integration validation and workflow coverage
test/registry-auth.mjs, .github/workflows/test.yaml, package.json
The integration test verifies authenticated package metadata and tarball requests, unchanged npmrc files, and install success across supported platforms and pnpm versions. The test script includes the added suites.
Action input documentation
README.md
The README documents registry input requirements, URL restrictions, token handling, pnpm requirements, and install: false behavior.

Explanation

Issue #13 requests support for registry-url, scope, and NODE_AUTH_TOKEN. The reviewed changes implement registry-url and registry-token authentication before pnpm install, with validation, token masking, isolated environment handling, unit tests, and integration tests. The changes do not implement scope or NODE_AUTH_TOKEN support. The PR summary explicitly limits the implementation to registry authentication through registry-url and registry-token.

Closing in favor of documenting pnpm's built-in pnpm_config__auth environment variable. It already configures registry routes and tokens together, supports multiple registries and scopes, and works with later pnpm commands when provided in their environment, so dedicated action inputs are unnecessary.

The replacement documentation is in #61: readable multiline JSON recipes for a scoped token and a registry-wide default token using "@", with a link to pnpm's _auth documentation: https://pnpm.io/npmrc#_auth.

Thanks for raising the private-registry use case!
