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.
