Babel transpiler for Node-RED

0.0.5 verified Fri May 01 auth: no javascript abandoned

A Node-RED node that uses Babel to transpile JavaScript code within a Node-RED flow. Version 0.0.5 is the latest release; appears to be experimental with no active maintenance. It allows specifying presets and input encoding but lacks documentation. Caution: unknown security implications as it executes transpiled code in Node-RED context.

Common errors

error Cannot find module 'babel-core' ↓

cause Missing dependency on Babel core packages (babel-core, babel-preset-es2015, etc.)

fix

Install required Babel packages: npm install babel-core babel-preset-es2015

Warnings

gotcha Package has no README, no documentation, and appears unmaintained. ↓

fix Consider using a different transpilation approach or Node-RED function node with Babel directly.

gotcha Version 0.0.5 is very early; likely contains bugs and security issues. ↓

fix Avoid using in production; audit code before use.

Quickstart

Shows how to install and use the babel node in Node-RED, including setting Babel preset and input encoding.

// Install node-red-contrib-babel
// npm install node-red-contrib-babel
// Use in Node-RED flow:
// Add 'babel' node to canvas
// Input: any color (default: #E9967A)
// Output: same color
// Set 'Babel preset' property (e.g., es2015)
// Input encoding: can set to specific encoding
// The node transpiles the incoming message's payload using Babel
