ERPDesktop plugin SDK — build, package, and publish plugins for the ERPDesktop marketplace

ERPDesktop Plugin SDK

Build, package, and publish plugins for the ERPDesktop marketplace. ERPDesktop plugins run as Python sidecars alongside the desktop app and communicate with ERPNext/Odoo over a secure JSON-RPC channel.

Install

pip install erpdesktop

Requires Python 3.11+.

---

Quick start

# Scaffold a new plugin
erpdesktop init com.yourcompany.myplugin

# Validate plugin.json
erpdesktop validate

# Package into a distributable .zip
erpdesktop package

# Publish to the marketplace
erpdesktop publish --changelog "Initial release"

Plugin lifecycle

from erpdesktop import PluginBase, log, event

class MyPlugin(PluginBase):
    plugin_id = "com.example.myplugin"
    plugin_version = "1.0.0"

    def on_start(self, config: dict) -> None:
        """Called when the plugin is started. Register your commands here."""
        log("info", "Plugin started", branch=config.get("branch"))
        self.register_command("ping", self.handle_ping)

    def on_stop(self) -> None:
        """Called on graceful shutdown."""
        log("info", "Plugin stopping")

    def on_config_change(self, config: dict) -> None:
        """Called when the user updates plugin settings."""
        pass

    def handle_ping(self, params: dict) -> dict:
        return {"pong": True}

if __name__ == "__main__":
    MyPlugin().run()

Modules

log — structured logging

from erpdesktop import log

log("info", "Sync complete", records=47, duration_ms=320)
log("error", "Device unreachable", device_id="K50-001")
# levels: debug | info | warn | error | critical

event — telemetry

Emit custom analytics events visible in the Publisher Dashboard. Do not include personal data or ERP record contents.

from erpdesktop import event

event("sync_completed", records=47, duration_ms=320)
event("device_connected", model="K50", firmware="2.1.3")

erpnext_request / odoo_request — ERP API

Call your connected ERPNext or Odoo site. Requires network.outbound.erpnext permission.

from erpdesktop import erpnext_request, odoo_request

# ERPNext
result = erpnext_request("GET", "/api/resource/Employee", params={"limit": 10})

# Odoo
result = odoo_request("POST", "/web/dataset/call_kw", json={...})

http — external HTTP

Make calls to third-party APIs. Requires network.outbound.internet permission and the endpoint declared in network_endpoints in your plugin.json.

from erpdesktop import http

resp = http.get("https://api.example.com/data", params={"key": "val"})
resp = http.post("https://api.example.com/sync", json={"records": [...]})

storage — persistent key-value store

from erpdesktop import storage

storage.set("last_sync", "2024-01-15T10:30:00")
value = storage.get("last_sync")          # returns str or None
value = storage.get("last_sync", "never") # with fallback

secrets — encrypted credential storage

Store API keys and passwords in the OS keychain — never in config files.

from erpdesktop import secrets

secrets.set("api_key", "sk-abc123")
key = secrets.get("api_key")          # returns str or None
key = secrets.get("api_key", "")      # with fallback

permissions — runtime permission checks

from erpdesktop import permissions

# Check before doing something sensitive
if permissions.require("network.outbound.internet"):
    result = http.get("https://api.example.com/data")

# Raise PermissionDenied automatically if not granted
permissions.enforce("network.outbound.erpnext")

# Check multiple
if permissions.has_all("network.outbound.erpnext", "storage.read"):
    ...

if permissions.has_any("network.outbound.erpnext", "network.outbound.internet"):
    ...

device — biometric/access device leasing

Claim exclusive access to a physical device (e.g. fingerprint reader) so two plugins don't conflict.

from erpdesktop import device

if device.lease("ZK-192.168.1.10", metadata={"model": "K50"}):
    # we have exclusive access
    ...
    device.release("ZK-192.168.1.10")

device.renew("ZK-192.168.1.10")            # extend lease
owner = device.is_leased("ZK-192.168.1.10") # returns plugin_id or None

notify — desktop notifications

from erpdesktop import notify

notify.send("Sync complete", "47 attendance records pushed to ERPNext")
notify.send("Device offline", "ZK-K50 not reachable", urgent=True)

i18n — translations

from erpdesktop import i18n

i18n.set_locale("ne")                              # Nepali
label = i18n.t("sync.button", fallback="Sync")
label = i18n.t("greeting", fallback="Hello {name}", name="Ram")

Place translation files at locales/<lang>.json in your plugin directory:

{ "sync.button": "सिंक गर्नुहोस्", "greeting": "नमस्ते {name}" }

plugin.json reference

{
  "id": "com.yourcompany.myplugin",
  "name": "My Plugin",
  "version": "1.0.0",
  "description": "What your plugin does.",
  "author": "Your Company",
  "plugin_type": "commercial",
  "entry": "main.py",
  "permissions": [
    "network.outbound.erpnext",
    "network.outbound.internet",
    "storage.read",
    "storage.write"
  ],
  "network_endpoints": [
    {
      "url": "https://api.example.com",
      "purpose": "Sync attendance records",
      "data_sent": "Employee IDs, timestamps"
    }
  ],
  "config_schema": {
    "branch": { "type": "string", "label": "Branch", "required": true }
  }
}

plugin_type — open_source (requires source_url), commercial, or private

network_endpoints — required when network.outbound.internet is declared. Shown to the user at install time. The SDK enforces the allowlist at runtime.
