node-red-contrib-simple-gate

library0.5.2jsnpmunverified

A Node-RED gate node that controls message flow by opening or closing a gate. Current stable version is 0.5.2, released with support for asynchronous context stores and improved persistence. Key differentiators: allows user-defined control topic and command strings, supports toggle and status commands, and can restore state from persistent context stores if available. Cannot queue messages; for queuing, use the companion node-red-contrib-queue-gate package. Compatible with Node-RED 0.18+.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

gate

✓ Install via npm: npm install node-red-contrib-simple-gate (then use the 'gate' node in the editor palette)

✗ Attempting to import JS module: const gate = require('node-red-contrib-simple-gate')

This is a Node-RED node, not a JavaScript library. It must be installed in your Node-RED user directory and added via the palette. No code import is required.

Shows that the package is a Node-RED node requiring installation and palette usage, not code imports.

// No code example; this is a Node-RED node. // To use: Install the package, then add a 'gate' node from the palette. // Configure control topic and command strings in the node edit dialog. // Send control messages with payload 'open', 'close', 'toggle', etc. on the control topic to change state.

Debug

Known issues

breakingState persistence: versions prior to 0.5.0 used only the default context store, which might be volatile. After upgrade, if using non-default stores, persistence may fail.

fix

Upgrade to 0.5.0 or later and configure appropriate context store in Node-RED settings.

affects: <0.5.0

breakingSupport for asynchronous context stores was added in 0.5.2; older versions may not work with async stores.

fix

Use version 0.5.2 or later.

affects: <0.5.2

breakingNot compatible with Node-RED version 0.18 and earlier.

fix

Upgrade Node-RED to 0.18+ or use a different gate node.

affects: >=0.0.0 <0.19.0

gotchaMessages that arrive when the gate is closed are discarded without warning; there is no queue or buffer.

fix

Use node-red-contrib-queue-gate if you need queuing.

affects: >=0.0.0

gotchaControl messages with payloads that are numbers or booleans are converted to strings before comparison; this may cause unexpected behavior if command strings are numeric.

fix

Ensure control message payloads are strings, or verify numerical equivalence.

affects: >=0.3.0

Errors

Common errors & fixes

Error: Cannot find module 'node-red-contrib-simple-gate'

Node-RED cannot locate the package because it was not installed correctly or is in the wrong directory.

fix

Navigate to your Node-RED user directory (typically ~/.node-red) and run: npm install node-red-contrib-simple-gate

Gate node not showing in palette

Node-RED needs to be restarted after installation, or the palette may not be updated.

fix

Restart Node-RED and check the palette manager. If still missing, try installing via Manage Palette in the editor.

TypeError: Cannot read property 'on' of undefined

Node-RED version is too old (pre-0.18) and incompatible with this node.

fix

Upgrade Node-RED to version 0.18 or higher.
