{"library":"node-red-contrib-loop-processing","title":"Node-RED Loop Processing Nodes","description":"This package provides three essential Node-RED nodes designed to facilitate flow looping within the Node-RED environment: `counter-loop`, `array-loop`, and `while-loop`. The `counter-loop` node enables `for-loop`-like behavior using a configurable counter, defining initial, terminal, and increment values. The `array-loop` node iterates over elements within a standard JavaScript array, akin to `forEach` or `for-of`, exposing the current key and value. The `while-loop` node executes based on a dynamic conditional expression. Currently at version 0.5.1, the package is actively maintained with a steady cadence of minor updates, frequently addressing bug fixes and introducing new features such as loop time limitations for `while-loop` and explicit variable resetting for iterative nodes. It significantly enhances Node-RED's capabilities by providing structured control flow mechanisms for repetitive tasks, which are not inherently available through basic core nodes.","language":"javascript","status":"active","last_verified":"Wed Apr 22","install":{"commands":["npm install node-red-contrib-loop-processing"],"cli":null},"imports":[],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"{\n  \"id\": \"e9a6e1a4.9c488\",\n  \"type\": \"tab\",\n  \"label\": \"Loop Processing Quickstart\",\n  \"disabled\": false,\n  \"info\": \"Quickstart for node-red-contrib-loop-processing\\n\\n1. **Install:** `npm install node-red-contrib-loop-processing` in your Node-RED user directory (~/.node-red), then restart Node-RED.\\n2. **Drag & Drop:** Place an 'Inject' node, a 'counter-loop' node, and two 'Debug' nodes on the canvas.\\n3. **Configure counter-loop:**\\n   - Property: `msg.payload.counter`\\n   - Initial value: `0`\\n   - Terminal value: `5`\\n   - Operator: `<=`\\n   - Increment value: `1`\\n   - Check 'Reset counter when loop exits'.\\n4. **Connect:**\\n   - Inject node -> counter-loop input\\n   - counter-loop 'true' output -> Debug node (set to display `msg.payload.counter`)\\n   - counter-loop 'false' output -> Debug node (set to display 'Loop Finished')\\n5. **Deploy and Test:** Click the inject button to see the counter increment in the debug sidebar.\"\n}\n","lang":"json","description":"This quickstart JSON demonstrates how to install the package and configure a basic `counter-loop` node in Node-RED, iterating a counter from 0 to 5 and logging each step, while also showing the loop completion.","tag":null,"tag_description":null,"last_tested":null,"results":[]},"compatibility":null}
