UCL API Client (TypeScript)

Universal Context Layer API client for browser and Node.js with a modular, extensible design.

Repository: https://github.com/unifiedcontextlayer/ucl-api-node

Install

npm install ucl-api
# or
yarn add ucl-api

Quick Start

import { UclClient } from 'ucl-api';

const ucl = new UclClient({
  workspaceId: 'ws_123',
  authToken: async () => '<your-token>',
  // baseUrl?: 'https://qa.fastn.ai',
  // stage?: 'LIVE',
  // fetch?: customFetch
});

const res = await ucl.connectors.auth({
  connectorId: 'c789',
  // tenantId?: 't123',
  // orgId?: 'o001',
  // workspaceId?: 'override-org', // overrides orgId if provided
  // refresh?: false
});

console.log(res.auth);

Design

Modular: constants, types, fetch resolver, http client, config normalizer, and client surface.
Cross-environment: Uses global fetch when available; falls back to cross-fetch in Node.js.
Token providers: Pass a string token or an async function for on-demand refresh without recreating the client.
Stable HTTP: Centralized header construction and error handling.

API

`class UclClient`

Constructor:

new UclClient({
  workspaceId: string,
  authToken?: string | () => string | Promise<string>,
  baseUrl?: string,      // default: https://live.fastn.ai/api
  stage?: string,        // default: LIVE
  fetch?: typeof fetch   // optional custom fetch
})

Methods:

setAuthToken(tokenOrProvider) — update token or async provider at runtime.
setFetch(fetchLike) — override the fetch implementation.

Namespaces:

`connectors.auth(params)`

Input:

{
  connectorId: string;           // required
  tenantId?: string;              // optional → header x-fastn-space-tenantid
  orgId?: string;                 // optional
  workspaceId?: string;           // optional; if provided, overrides orgId
  refresh?: boolean;              // optional
}

Behavior:

Headers include x-fastn-space-id (from constructor), stage (default LIVE), x-fastn-custom-auth: true, and authorization (your token).
orgId resolution: use workspaceId (param) if provided; else orgId; else 'community'.
Response shape: { auth: { ... } } where auth carries OAuth fields like access_token, expires_in (when applicable) or connector-specific credentials.

Returns:

type AuthResponse = { auth: Record<string, unknown> };

Error Handling

Non-2xx responses throw Error('HTTP <status> <statusText>: <body>').
Missing auth token throws: authToken is required. Provide it in config or via setAuthToken().

Testing

This package ships with Jest tests. Run:

npm test

To run live E2E against your workspace, export envs (or create a local .env):

export UCL_E2E=1
export UCL_BASE_URL=https://live.fastn.ai/api
export UCL_WORKSPACE_ID=<your-workspace-id>
export UCL_AUTH_TOKEN='<your-token>'
export UCL_CONNECTOR_ID=<your-connector-id>
export UCL_ORG_ID=<your-org-id>
export UCL_REFRESH=false
export UCL_TENANT_ID=<your-tenant-id>

npm test
