From cdab47dd2f0be07f33315f43022b2693dbccb3ac Mon Sep 17 00:00:00 2001 From: garthdb Date: Fri, 23 Jan 2026 13:32:39 -0700 Subject: [PATCH 1/3] feat: add OIDC trusted publishing support for npm Add support for npm OIDC trusted publishing, eliminating the need for long-lived NPM tokens. This implementation: - Adds 'oidcAuth' input parameter to enable OIDC mode - Validates npm version >= 11.5.1, id-token permission, and no NPM_TOKEN conflict - Skips .npmrc creation when OIDC is enabled to allow npm auto-detection - Maintains full backward compatibility with existing NPM_TOKEN workflows - Provides clear, actionable error messages for validation failures Features: - Strict validation with helpful error messages - Comprehensive test coverage (26 tests passing) - Full documentation with migration guide - Zero .npmrc creation in OIDC mode for seamless npm integration Closes #1 --- README.md | 90 ++++++++++++++++++++++++ action.yml | 4 ++ src/index.test.ts | 172 ++++++++++++++++++++++++++++++++++++++++++++++ src/index.ts | 63 ++++++++++------- src/oidc.test.ts | 147 +++++++++++++++++++++++++++++++++++++++ src/utils.ts | 35 ++++++++++ 6 files changed, 488 insertions(+), 23 deletions(-) create mode 100644 src/index.test.ts create mode 100644 src/oidc.test.ts diff --git a/README.md b/README.md index 5ea2e5e5..0c073133 100644 --- a/README.md +++ b/README.md @@ -12,6 +12,7 @@ This action for [Changesets](https://github.com/changesets/changesets) creates a - title - The pull request title.
