# Package exports

> Find the import path for a core API or integration package.

Import contract helpers such as `route()` from `@hulla/api`. Import client and server APIs from their separate entrypoints below. Each integration package is listed with its purpose and documentation.

| Entrypoint                                                                    | Primary exports                                                                                          |

Every host integration is a separate package so client bundles do not retain framework or Node dependencies. Packages with distinct runtime surfaces use explicit subpaths: `@hulla/api-next/client` and `/server`, `@hulla/api-nuxt/client` and `/server`, `@hulla/api-sveltekit/server` and `/remote`, `@hulla/api-cloudflare/pages`, and `@hulla/api-node/http`.

Use the relevant integration guide for its mounting function and native context types. Application code should prefer the smallest public entrypoint that owns the capability it needs; consult the package declarations for the complete symbol inventory.

## Result-returning clients

`@hulla/api-control` adapts each typed client call to a resolved `Result`, while preserving the route's success and declared-error response types. See [Result-returning clients](https://hulla.dev/docs/api/integrations/control.md) for the complete setup, failure categories, and query-library tradeoff.
