pve-client

pve-client

TypeScript-first API client for Proxmox VE.

It provides a typed API surface generated from the Proxmox spec, so endpoint paths, query/body fields, and return types are available through autocomplete.

Features

• Typed endpoint methods for Proxmox VE APIs
• Token auth and username/password login flow
• Automatic path/query/body handling
• Proxmox-style response unwrapping ({ data: ... } -> data)
• Works with Node.js fetch and supports custom HTTPS agents

Installation

npm install pve-client

Quick Start

Token Authentication (recommended)

import { Client } from "pve-client";
import { Agent } from "node:https";

const client = new Client({
  baseUrl: "https://pve.example.com:8006",
  apiToken: "PVEAPIToken=root@pam!mytoken=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  // only needed for self-signed certs
  agent: new Agent({ rejectUnauthorized: false }),
});

const nodes = await client.api.nodes.list();
console.log(nodes);

Username/Password Authentication

import { Client } from "pve-client";
import { Agent } from "node:https";

const client = new Client({
  baseUrl: "https://pve.example.com:8006",
  username: "root",
  password: "your-password",
  realm: "pam", // optional, defaults to "pam"
  agent: new Agent({ rejectUnauthorized: false }),
});

await client.login();
const nodes = await client.api.nodes.list();
console.log(nodes);

Using .env

PVE_BASE_URL=https://pve.example.com:8006
PVE_API_TOKEN=PVEAPIToken=root@pam!mytoken=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

import "dotenv/config";
import { Client } from "pve-client";

const client = new Client({
  baseUrl: process.env.PVE_BASE_URL!,
  apiToken: process.env.PVE_API_TOKEN!,
});

const nodes = await client.api.nodes.list();
console.log(nodes);

Common Calls

Get cluster overview and nodes

const cluster = await client.api.cluster.index();
const nodes = await client.api.nodes.list();

Path-based endpoints

const nodeStatus = await client.api.nodes.get("pve").status.get();

Endpoints with optional parameters

// no params required
const version = await client.api.version.version();

// optional query/body can still be passed
const pools = await client.api.pools.index({
  $query: { type: "qemu" },
});

Request Argument Shape

Methods accept an object with optional special fields depending on endpoint:

• $path: path parameters (usually handled by path helper methods like .get("node"))
• $query: query string parameters
• $body: request body (sent as application/x-www-form-urlencoded)
• $headers: additional request headers

Example:

await client.api.access.permissions({
  $query: { path: "/", userid: "root@pam" },
});

Authentication Notes

• apiToken accepts either:
  • full: PVEAPIToken=user@realm!token=secret
  • shorthand: user@realm!token=secret
• For username/password auth, call await client.login() before other API calls.
• For self-signed certificates, pass a custom https.Agent with rejectUnauthorized: false.
• Some Proxmox functionalities are only accessible with username/password ticket auth (session + CSRF) and are not available to API tokens, even if token permissions are broad.

Terminal Example (Local TTY)

There is a runnable example that opens a VM terminal and binds it to your local terminal (stdin/stdout):

npm run example/terminal -- 100

Or set PVE_VMID in .env and run without CLI args:

npm run example/terminal

Example .env (username/password required for terminal helper):

PVE_BASE_URL=https://pve.example.com:8006
PVE_USERNAME=root
PVE_PASSWORD=your-password
PVE_REALM=pam
PVE_VMID=100

Controls:

• Ctrl-] disconnects from the local bridge.
• Terminal resize is forwarded automatically.

Live Tasks Example

There is also a terminal example that continuously displays cluster tasks:

npm run example/tasks

Optional .env values:

# required
PVE_BASE_URL=https://pve.example.com:8006

# auth: use token OR username/password
PVE_API_TOKEN=PVEAPIToken=root@pam!tokenid=secret
# or:
PVE_USERNAME=root
PVE_PASSWORD=your-password
PVE_REALM=pam

# optional polling interval (default 2000)
PVE_TASKS_POLL_INTERVAL_MS=2000

Error Handling

Non-2xx responses throw an Error including status and response text:

try {
  await client.api.nodes.list();
} catch (error) {
  console.error(error);
}

Development

npm run build
npm test
npm run test:coverage
npm run example/auth
npm run example/terminal -- 100
npm run example/tasks

Testing

This project uses Vitest in a Node environment.

• npm test runs all tests
• npm run test:coverage runs tests and generates coverage reports (text, json, html)

Current high-value suites cover:

• Client authentication, request handling, events, and task polling
• native_fetch request construction, header/body behavior, and abort handling
• TimerPulledEventEmitter polling, filtering, dedupe, and error flows
