Node-RED Contrib Patterns — v5 OSS

node-red-contrib-modbus v5.x — public Open Source, LTS.

v5 vs v6

	v5 (this)	v6 (closed)
TLS	—	Modbus-Client-TLS
Server	Modbus-Server here	separate package
Log	debug	winston
Package	node-red-contrib-modbus	@plus4nodered/...

Layout

src/modbus-*.js, src/modbus-server.js
src/core/
modbus/          # built — do not hand-edit
test/units/, test/e2e/

Testing

const helper = require('node-red-node-test-helper')
helper.init(require.resolve('node-red'))
// require from ../../src/ — see test/units/modbus-client-test.js

Dynamic ports: getPort / getPorts / withEphemeralPorts in test/helper/ (process-global allocator, mocha-parallel safe). Test metrics: Winston via measure() — enable with MODBUS_TEST_LOG=info (silent by default for CI dot mode). Production logging stays debug (DEBUG=contribModbus*).

Server Node

Modbus-Server uses jsmodbus — stays in v5 package. Spec server changes in Team 1.

Debug

DEBUG=contribModbus* npm run test:units

OSS

• StandardJS, BSD-3-Clause
• Stable public API in v5
• CHANGELOG for user-visible changes

Commands

npm run build && npm run lint && npm test
npm run test:units
npm run mocha:base -- test/units/modbus-server-test.js
