# Migrate from @neondatabase/api-client to @neon/sdk

:::callout{intent="note" title="@neondatabase/api-client still works"}
The legacy [`@neondatabase/api-client`](https://www.npmjs.com/package/@neondatabase/api-client) package continues to work. [`@neon/sdk`](https://www.npmjs.com/package/@neon/sdk) is the recommended replacement for new projects and for teams that want fetch-based, zero-dependency Platform API access with ergonomic workflows.
:::

This guide maps common `@neondatabase/api-client` patterns to [`@neon/sdk`](/guides/apis-sdks-reference-typescript-sdk). For full method reference, see the [Neon Management SDK](/guides/apis-sdks-reference-typescript-sdk) documentation.

## What changes

|               | `@neondatabase/api-client`                      | `@neon/sdk`                                                              |
| ------------- | ----------------------------------------------- | ------------------------------------------------------------------------ |
| HTTP client   | Axios                                           | `fetch` (zero runtime dependencies)                                      |
| Factory       | `createApiClient({ apiKey })`                   | `createNeonClient({ apiKey })`                                           |
| Method layout | Flat (`listProjects`, `createProjectBranch`, …) | Namespaced (`neon.projects.list()`, `neon.branches.create()`, …)         |
| Success path  | `response.data` on Axios responses              | `{ data, error }` by default, or bare resource with `throwOnError: true` |
| Errors        | `AxiosError` + `error.response`                 | Typed `NeonError` hierarchy (`kind`: `api`, `not_found`, `auth`, …)      |
| Node.js       | Broader support                                 | **≥ 20.19** (or any runtime with global `fetch`)                         |
| Low-level API | Generated methods on the client                 | `raw.*` functions + `neon.client`                                        |

## Install and swap the package

```bash
npm uninstall @neondatabase/api-client
npm install @neon/sdk
```

Update imports:

```typescript
// Before
import { createApiClient } from '@neondatabase/api-client';

// After
import { createNeonClient } from '@neon/sdk';
```

## Client setup

```typescript
// Before
const apiClient = createApiClient({
  apiKey: process.env.NEON_API_KEY!,
});

// After — check { data, error } on each call
const neon = createNeonClient({
  apiKey: process.env.NEON_API_KEY!,
});

// After — throw on error (closer to try/catch style)
const neon = createNeonClient({
  apiKey: process.env.NEON_API_KEY!,
  throwOnError: true,
});
```

`createNeonClient` also supports `orgId`, `waitForReadiness`, `retries`, `baseUrl`, and a custom `fetch` implementation. See [Neon Management SDK](/guides/apis-sdks-reference-typescript-sdk#client-configuration).

## Method mapping

Common Platform API calls and their `@neon/sdk` equivalents:

| `@neondatabase/api-client`             | `@neon/sdk`                                                                     |
| -------------------------------------- | ------------------------------------------------------------------------------- |
| `getCurrentUserOrganizations()`        | `neon.user.organizations()`                                                     |
| `getCurrentUserInfo()`                 | `neon.user.me()`                                                                |
| `listProjects({ org_id })`             | `neon.projects.list({ org_id }).page()` or `.all()`                             |
| `createProject({ project })`           | `neon.projects.create({ name, region_id, … })`                                  |
| `getProject(projectId)`                | `neon.projects.get(projectId)`                                                  |
| `deleteProject(projectId)`             | `neon.projects.delete(projectId)`                                               |
| `listProjectBranches({ projectId })`   | `neon.branches.list(projectId).page()` or `.all()`                              |
| `createProjectBranch(projectId, body)` | `neon.branches.create(projectId, input)` or `neon.branches.createAndConnect(…)` |
| `getConnectionUri(projectId, query)`   | `neon.postgres.connectionString({ projectId, … })`                              |
| `listProjectBranchDatabases(…)`        | `neon.postgres.databases.list(…)`                                               |
| `createProjectBranchDatabase(…)`       | `neon.postgres.databases.create(…)`                                             |
| `listProjectBranchRoles(…)`            | `neon.postgres.roles.list(…)`                                                   |
| `createProjectBranchRole(…)`           | `neon.postgres.roles.create(…)`                                                 |
| `listProjectEndpoints(projectId)`      | `neon.postgres.endpoints.list(projectId)`                                       |
| `listApiKeys()`                        | `neon.apiKeys.list()`                                                           |
| `getActiveRegions()`                   | `neon.regions.list()`                                                           |

Endpoints that are not wrapped in an ergonomic namespace remain available through [`raw`](/guides/apis-sdks-reference-typescript-sdk#raw-layer).

## Error handling

**Before** — Axios throws; inspect `error.response`:

```typescript
try {
  const response = await apiClient.getProject(projectId);
  console.log(response.data.project);
} catch (error) {
  // AxiosError — error.response?.status, error.response?.data
}
```

**After** — default `{ data, error }` envelope:

```typescript
const { data: project, error } = await neon.projects.get(projectId);
if (error) {
  if (error.kind === 'not_found') {
    // handle 404
  }
  throw error;
}
console.log(project);
```

**After** — `throwOnError: true` on the client or per call:

```typescript
const neon = createNeonClient({ apiKey, throwOnError: true });
const project = await neon.projects.get(projectId); // throws NeonError on failure
```

## Side-by-side examples

### List projects

```typescript
// Before
const orgs = await apiClient.getCurrentUserOrganizations();
const orgId = orgs.data.organizations[0].id;
const response = await apiClient.listProjects({ org_id: orgId });
console.log(response.data.projects);

// After
const { data: orgs, error: orgsError } = await neon.user.organizations();
if (orgsError) throw orgsError;

const { data: page, error } = await neon.projects.list({ org_id: orgs[0].id }).page();
if (error) throw error;
console.log(page.items);
```

### Create a project with a connection string

```typescript
// Before
const response = await apiClient.createProject({
  project: { name: 'my-app', region_id: 'aws-us-east-1', pg_version: 17 },
});
const uri = response.data.connection_uris[0].connection_uri;

// After — waits for provisioning; data is { project, connectionString }
const { data, error } = await neon.projects.createAndConnect({
  name: 'my-app',
  region_id: 'aws-us-east-1',
  pg_version: 17,
});
if (error) throw error;
const { project, connectionString } = data;
```

### Create a branch with compute

```typescript
// Before
import { EndpointType } from '@neondatabase/api-client';

await apiClient.createProjectBranch(projectId, {
  branch: { name: 'dev-1', parent_id: parentBranchId },
  endpoints: [{ type: EndpointType.ReadWrite }],
});

// After — read-write compute is attached by default
const { data, error } = await neon.branches.create(projectId, {
  name: 'dev-1',
  parent_id: parentBranchId,
});
if (error) throw error;
const branch = data;
```

### Create a database

```typescript
// Before
await apiClient.createProjectBranchDatabase(projectId, branchId, {
  database: { name: 'mydb', owner_name: 'neondb_owner' },
});

// After
const { error } = await neon.postgres.databases.create(projectId, branchId, {
  name: 'mydb',
  owner_name: 'neondb_owner',
});
if (error) throw error;
```

## Raw layer changes in 1.0

If you adopted `@neon/sdk` **0.x** and used `raw.*` directly, **1.0 changes the raw contract**:

| 0.x                                            | 1.0                                               |
| ---------------------------------------------- | ------------------------------------------------- |
| hey-api `{ data, request, response }` envelope | `{ data, error }` `NeonResult`                    |
| `responseStyle: "data"`                        | **Removed**                                       |
| `throwOnError: true` needed workarounds        | Returns the bare resource; types narrow correctly |

```typescript
// Before (0.x)
const project = await raw.getProject({
  client: neon.client,
  path: { project_id: projectId },
  throwOnError: true,
  responseStyle: 'data',
});

// After (1.0)
const project = await raw.getProject({
  client: neon.client,
  path: { project_id: projectId },
  throwOnError: true,
});
```

Drop any `unwrapRaw` helpers or `responseStyle` usage.

## Types

Import request/response types from `@neon/sdk` instead of `@neondatabase/api-client`:

```typescript
import type { Project, Branch } from '@neon/sdk';
```

Some generated type names changed (for example, `DataAPI*` → `DataApi*`). Endpoint types are string unions (`"read_write"` / `"read_only"`) rather than enums.

## What you gain

- **Workflow helpers** such as `projects.createAndConnect` and `branches.createAndConnect` that poll operations and return `{ project, connectionString }` or `{ branch, endpoint, connectionString }`. `create` returns the resource; `branches.create` attaches a read-write endpoint unless you pass `noCompute: true`.
- **Readiness polling** via `waitForReadiness` and `neon.operations.waitFor`
- **Automatic retries** on safe statuses (`423`, `429`, `503`)
- **Ergonomic beta APIs** for storage, functions, credentials, AI gateway, snapshots, and branch-scoped Managed Better Auth (`neon.auth`, `neon.storage`, …)
- **Tree-shakeable raw imports** from `@neon/sdk/raw`
