This repository is a semantic-release plugin that automates the publishing of npm packages. It implements four lifecycle steps: verifyConditions (validates configuration and authentication), prepare (updates package.json version and optionally creates a tarball), publish (publishes the package to the npm registry), and addChannel (adds a release to a dist-tag). The plugin supports both token-based authentication (via NPM_TOKEN) and OIDC-based trusted publishing for GitHub Actions, GitLab Pipelines, and CircleCI. It can publish to custom registries, handle scoped packages, and skip publishing for private packages or when npmPublish is false. The architecture is a set of exported async functions that receive pluginConfig and context from semantic-release, delegating to internal lib modules. External dependencies include the npm CLI (executed via execa), fs-extra for file operations, registry-auth-token for authentication, env-ci for CI provider detection, and @actions/core for OIDC token retrieval. The codebase is well-structured with clear separation of concerns, comprehensive error handling using AggregateError, and extensive test coverage with both unit and integration tests.
