# Packages (/docs/reference/packages)

> The publishable Better IAM packages with their subpath exports, runtime dependencies, and peer dependencies.



The workspace publishes one package per concern, plus the umbrella `better-iam` package that depends on all of them
and re-exports each as a subpath. Every package is ESM, ships TypeScript declarations, and requires Node.js 22.12 or
newer. Pick individual packages when a service needs only part of the platform; see
[Installation](/docs/installation) for the subpath map.

## How the packages depend on each other [#how-the-packages-depend-on-each-other]

Arrows point from a package to the workspace packages it depends on (generated from the manifests; the umbrella
package, which depends on all of them, is omitted). Browser-side packages (`client`, `react`, `vue`, `svelte`)
never depend on `server` or `auth`, so they never pull server code or native modules into a bundle.

`@better-iam/core` has no dependencies and runs in any JavaScript runtime, which is why the
[policy playground](/playground) can evaluate policies in your browser with the same engine the server uses.
