@layers/amba-node

Amba is the agent-native backend-as-a-service for mobile and web apps. This package is the Node.js SDK — the server-side companion to @layers/amba-web, with the full 34-module Amba surface and idiomatic Node ergonomics (Connect-style middleware, per-user asUser(...) scoping for bulk operations).

Install

npm install @layers/amba-node

Configure + first call

import { AmbaClient } from "@layers/amba-node";

const amba = await AmbaClient.configure({
  projectId: process.env.AMBA_PROJECT_ID!,
  clientKey: process.env.AMBA_CLIENT_KEY!,
  // Required for amba.asUser(...), which user-scoped calls go through.
  serverKey: process.env.AMBA_SERVER_KEY,
});

// verifiedUserId comes from your authenticated application context or a
// verified webhook payload.
await amba.asUser(verifiedUserId).events.track("webhook_received", { source: "stripe" });

The shared amba client carries no user, so user-scoped calls such as events.track go through amba.asUser(userId).

Per-user scoped calls

// Attribute the event to a specific user without minting a session.
await amba.asUser(userId).events.track("checkout_completed", { amount: 99 });

Express middleware

import express from "express";
import { AmbaClient } from "@layers/amba-node";

const amba = await AmbaClient.configure({
  projectId: process.env.AMBA_PROJECT_ID!,
  clientKey: process.env.AMBA_CLIENT_KEY!,
  serverKey: process.env.AMBA_SERVER_KEY,
});

const app = express();
app.use(amba.middleware());

app.post("/orders", async (req, res) => {
  // res.locals.userId is set by your own auth middleware from a verified session.
  await req.amba.asUser(res.locals.userId).events.track("order_placed");
  res.sendStatus(204);
});
