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

Summary: Step-by-step migration from @neondatabase/api-client to @neon/sdk: package install, createNeonClient, namespace method mapping, error handling, and raw layer 1.0 breaking changes. Use this page when updating scripts, CI jobs, or apps that call the Neon Platform API with TypeScript.

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

Move Platform API automation from the legacy Axios client to the official fetch-based SDK

Note: @neondatabase/api-client still works

The legacy @neondatabase/api-client package continues to work. @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. For full method reference, see the Neon Management 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.

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.

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
