@dianemo/plugin-printnode

PrintNode plugin — remote print job dispatch

A plugin for dianemo, which distributes one API rate limit across every process that draws on it.

npm install @dianemo/core @dianemo/backend-redis @dianemo/plugin-printnode ioredis

Setup

import RequestHandler, { buildClientName } from "@dianemo/core";
import { redisBackend } from "@dianemo/backend-redis";
import printNode from "@dianemo/plugin-printnode";
import { Redis } from "ioredis";

const handler = new RequestHandler({
  key: process.env.DIANEMO_KEY!,
  backend: redisBackend(new Redis(process.env.REDIS_URL!)),
});

export const requests = handler.use(printNode);

// Credentials are encrypted into the backend, so every process pointed at this
// Redis rebuilds the same client and draws on one shared budget.
await handler.addTemplateClient("printNode", {
  instanceId: "main",
  baseUrl: "https://api.printnode.com",
  token: process.env.PRINTNODE_API_KEY!,
});

// "printNode:_:main" — <template>:<organizationId | "_">:<instanceId>
const account = buildClientName("printNode", { instanceId: "main" });

const printers = await requests.printNode.getAllPrinters(account);

Register another account by calling addTemplateClient again with a different instanceId. Pass organizationId alongside it in a multi-tenant deployment: it becomes the second segment of the client name, keeping each tenant's credentials and budget separate.

API notes. The rate-limit evidence behind this package's calibration, the wire quirks it works around, and the questions still open are in docs/printnode-api.md — it ships with the package.
