Opinionated standard library for Webiny. This is an internal package — we make breaking changes freely and do not follow semver for external consumers.
Services are built on a lightweight dependency injection system. Each feature follows the same three-layer pattern: an abstraction (DI token + interface), an implementation (concrete class), and a feature (registers the implementation in the DI container). This keeps code testable and lets different environments (Node.js, browser) swap implementations behind the same interface.
The package is ESM-only and ships three subpath exports. Because each is a separate entry point, Node.js-specific code is never bundled into a browser build and vice versa — unless you explicitly import the wrong subpath.

Versioning and publishing are managed by Changesets. The version in package.json is the real published version, bumped automatically when a version PR is merged. To record a version bump, run yarn changeset before opening a PR. There are no major version bumps — breaking changes may land on minor releases.
