Object index
Tired of looping through your array of objects or object of arrays? End with it, index it by key you want, query it like a database!
Install
$ npm i object-indexed-map
Example of usage
Take a look at the example or at the tests.
Support for immutable.js
Take a look at the tests again and look for immutable-driver
test.
warning in order for this to be working, you have to use immutable.Record
as immutable.Map
, because Record
implements getters!
.
The reason for this is that his library should not care how to get values from an object.
So it just uses native Javascript getters:
let value = object[key]
anything like:
let value = object.get(key)
cannot be used.
So your tree must be defined as a immutable.Record
, which is easy and a good practice:
const Structure = immutable.Record({
'todos': immutable.List(),
'people': immutable.List()
})
const Todo = immutable.Record({
'id': null,
'text': ''
})
const Human = immutable.Record({
'id': null,
'name': ''
})
const testTree = Structure({
'todos': immutable.List([
Todo({
'id': 12,
'text': 'Todo num 12'
}),
Todo({
'id': 32,
'text': 'Todo num 32'
})
]),
'people': immutable.List([
Human({
'id': 1,
'name': 'vojta'
}),
Human({
'id': 2,
'name': 'honza'
})
])
})
