@fransiscuss/greenflux

An unofficial TypeScript SDK for Greenflux CPMS APIs. It has four independently configured clients: Charge Assist, Platform/CPO/eMSP, Charge Location Management, and Remote Commands. It uses the native fetch available in Node.js 20+ and does not ship a runtime dependency.

This project is not affiliated with Greenflux.

Install

npm install @fransiscuss/greenflux

Quick start

Keep API credentials in environment variables or a secrets manager, never in source control.

import { ChargeAssistClient, GreenfluxPlatformClient } from "@fransiscuss/greenflux";

const chargeAssist = new ChargeAssistClient({
  baseUrl: process.env.GREENFLUX_CHARGE_ASSIST_BASE_URL!,
  apiKey: process.env.GREENFLUX_CHARGE_ASSIST_KEY!,
});
const platform = new GreenfluxPlatformClient({
  baseUrl: process.env.GREENFLUX_PLATFORM_BASE_URL!,
  token: process.env.GREENFLUX_PLATFORM_TOKEN!,
});

const location = await chargeAssist.getLocationById("your-location-id", {
  "filter.powerType": "DC",
});
const locations = await platform.getCpoLocations("2.0", { limit: 10 });

ChargeAssistClient defaults to the gateway header Ocp-Apim-Subscription-Key. For an endpoint requiring the OpenAPI-style Authorization: ApiKey … header, set chargeAssistAuthentication: "authorization-api-key".

All clients expose get, post, put, patch, and delete for APIs not yet wrapped by a convenience method. Non-2xx responses throw GreenfluxApiError, which contains status, response, and response headers. The raw body can contain customer data, so redact it before forwarding an error to a log aggregator — see SECURITY.md.

Live Charge Assist example

The examples live in the repository rather than in the published package; clone the repo to run them. examples/charge-assist-session.ts demonstrates a real start → status → stop flow. It is safe by default: without --run-live, it performs only a read-only location request. Set the GREENFLUX_CHARGE_ASSIST_*, GREENFLUX_APP_TOKEN, GREENFLUX_LOCATION_ID, GREENFLUX_EVSE_UID, and GREENFLUX_PAYMENT_METHOD_ID environment variables before using it.

npm run example:charge-assist -- --run-live

Use a dedicated test tenant/station. This command can start a physical charging session and incur costs.

Integration checks

The local harness starts a real HTTP server and verifies request paths, repeated query parameters, authentication, JSON payloads, and error handling without Greenflux credentials:

npm run integration

npm run smoke is an opt-in, read-only connectivity check against a real CPMS account. Copy .env.example values into your shell; it requires GREENFLUX_PLATFORM_BASE_URL and GREENFLUX_PLATFORM_TOKEN. It is intentionally never run by GitHub Actions.

Development

npm ci
npm run verify

The CI workflow runs type checking, unit tests, the local HTTP integration harness, and checks the publishable npm tarball. Releases use Conventional Commit PR titles and release-please.

Security

Report vulnerabilities privately through GitHub Security Advisories. See SECURITY.md for how to handle credentials.
