Node.js SDK

TypeScript SDK for the MeshAPI AI model gateway — an OpenAI-compatible API that proxies to OpenRouter with multi-tenant key management, rate limiting, and prompt templates.

Supports Node.js 18+ with full TypeScript strict-mode types, native fetch, and streaming via AsyncIterable.

Installation

$ npm install meshapi-node-sdk
$ # or
$ pnpm add meshapi-node-sdk
$ # or
$ yarn add meshapi-node-sdk

Quick Start

1 import { MeshAPI } from "meshapi-node-sdk";
2 
3 const client = new MeshAPI({
4   baseUrl: "https://api.yourdomain.com",
5   token: "rsk_01JXXXXXXXXXXXXXXXXXXXXXXXXX", // data-plane API key
6 });

Authentication

All requests require a Mesh API key (prefixed with rsk_).

1 const client = new MeshAPI({
2   baseUrl: "https://api.yourdomain.com",
3   token: "rsk_01JXXXXXXXXXXXXXXXXXXXXXXXXX",
4 });

This key provides access to all endpoints, including completions, models, templates, images, and batch jobs.

Configuration Options

1 const client = new MeshAPI({
2   baseUrl: "https://api.yourdomain.com",  // required
3   token: "rsk_...",                        // required
4   timeoutMs: 30_000,                       // default: 60_000 (60s)
5   signal: myAbortController.signal,        // optional global AbortSignal
6   fetch: customFetch,                      // optional fetch override (for mocking/polyfills)
7 });
