### Patch Changes

* 47cda20: Add optional `shardSubdomain` shape option to auto-shard the url subdomain in development. This solves the slow shapes in development problem without needing HTTP/2 or system level deps like Caddy or mkcert.

## 0.0.2

### Patch Changes

* 0dd1f0c: feat: add support for parameters in where clauses to clients
* eb8167a: Implement `ELECTRIC_POOLED_DATABASE_URL` optional env var to perform queries with separate, potentially pooled connection string.
* f6a3265: Fix OpenAPI spec 409 response schema
* f1a9247: feat!: change the wire protocol to remove `offset` and add an explicit `lsn` header. Only valid offset now is the one provided in headers
* 4d7b8ba: Add support for shapes on partitioned tables
* dd5aeab: This PR adds support for function-based options in the TypeScript client's params and headers. Functions can be either synchronous or asynchronous and are resolved in parallel when needed.

  ```typescript
  const stream = new ShapeStream({
    url: 'http://localhost:3000/v1/shape',
    params: {
      table: 'items',
      userId: () => getCurrentUserId(),
      filter: async () => await getUserPreferences(),
    },
    headers: {
      Authorization: async () => `Bearer ${await getAccessToken()}`,
    },
  })
  ```

  ## Common Use Cases

  * Authentication tokens that need to be refreshed
  * User-specific parameters that may change
  * Dynamic filtering based on current state
  * Multi-tenant applications where context determines the request
