Advanced tools
Simple tool for storing/retrieving objects events based hierarchical keypaths.
Simple tool for storing/retrieving objects events based hierarchical keypaths.
It lets you store and retrive objects that are at an equal or deeper key path than what you give it.
npm install key-tree-store
Assume you've got a structure like this:
{
'first': [ {obj: 1}, {obj: 2} ],
'first.stuff': [ {obj: 3} ],
'first.something.other': [ {obj: 4}, {obj: 5} ]
}
Then you can retrive it by key. Where it returns anything at or deeper than level supplied.
var KeyTree = require('key-tree-store');
var tree = new KeyTree();
tree.add('first', {id: 'one'});
tree.add('first.second', {id: 'two'});
tree.add('first.second', {id: 'three'});
tree.add('first.second.third', {id: 'four'});
// now we can retrieve them by key
tree.get('first'); // returns all of them
tree.get('first.second'); // returns array of objects two, three and four
tree.get('first.second.third'); // returns array of object four;
// the `get` method returns them all in an array
// if we still need them grouped by key we can use
// `getGrouped`
tree.getGrouped('first.second'); // returns {'first.second': [...], 'first.second.third': [...]}
// calling `.get()` or `.getGrouped` without arguments
// returns all in appropriate format
// that's all there is to it
removing items:
var KeyTree = require('key-tree-store');
var tree = new KeyTree();
var obj1 = {obj: '1'};
tree.add('key.path', obj1);
// removes it no matter what key
tree.remove(obj1);
running items:
// as a shortcut, there's also the `run` method
// to help you run functions that match they keypath
// this assumes you're storing functions, of course.
var KeyTree = require('key-tree-store');
var tree = new KeyTree();
tree.add('key.path', function () {
console.log('function ran!');
});
tree.run('key'); //=> function ran!
// you can also optionally pass a context or arguments to run them with
tree.run('key', {some: 'object'});
// with arguments
tree.run('key', {some: 'object'}, 'arg1', 'arg2');
