etcd-flatten

etcd-flatten

Flatten the results of a recursive etcd query into a flat object with keys and values

installation

$ npm install etcd-flatten

usage

Imagine we have some deeply nested keys in etcd:

$ etcdctl ls --recursive

/shapes
/shapes/circle
/shapes/circle/red
/shapes/circle/green
/shapes/square
/shapes/square/red

We can do a recursive query and get a tree like structure

etcd-flatten will take this tree structure and return a flat object with paths mapped to values and no directories included

var etcdjs = require('etcdjs')
var flatten = require('etcd-flatten')

var etcd = etcdjs('127.0.0.1:4001')

etcd.get('/shapes', {
	recursive:true
}, function(err, results){

	if(!err && results.node){
		var leafs = flatten(results.node)
		console.dir(leafs)	
	}
	
})

/*
{
	'/shapes/circle/red':'CIRCLE RED',
	'/shapes/circle/green':'CIRCLE GREEN',
	'/shapes/square/red':'SQUARE RED'
}
	
*/

api

var flatObject = flatten(etcdResults)

Pass the top-level node from an etcd query.

A flat object containing all leafs by their path is returned.
