cli-util-proxy v0.1.4

cli-util-proxy

Create proxy for any CLI util, decorate/transform its behavior.

Installation

npm i cli-util-proxy

Example

Add shortcuts to kubectl

NOTE: args - is process.argv parsed by minimist + params property which contains positional params

#!/usr/bin/env node
const { createProxy } = require('cli-util-proxy') 

createProxy('kubectl')
	.proxy('g p', () => 'get pods')
	.proxy('c c', () => 'config current-context')
	.proxy('l <query>', async args => {
		const podName = await findPodNameByQuery(args.params.query)
		return `logs ${podName}`
	})
	.run()

Make executable

chmod +x path/to/kubectl.js

Add alias

alias k="path/to/kubectl.js"

Use it

k g p
# same as
k get pods

k c c
# same as
k config current-context

# fallbacks to kubectl
k config view

Interrupt command and don't proxy forward

This will replace kubectl get pods

createProxy('kubectl')
	.proxy('get pods', (args, done) => {
		console.log('No pods for you!')
		done()
	})
