js-path-resolver

1.0.14 • Public • Published

Overview

Resolves paths in Javascript objects, providing tools to get, set, replace, or remove the resolved item.

Install

Web Browser

<script src="https://unpkg.com/js-path-resolver/dist/index.js"></script>
<script>
const resolver = jsPathResolver.default;
</script>

Node

import resolver from  'js-path-resolver';

Usage

import resolver from 'js-path-resolver'
 
const state = {
    lists:{
        todo:[
            {caption:'wake up', completed:true},
            {caption:'eat', completed:false}
        ]
    }
}
 
const info = resolver(state, 'lists.todo.1.completed')
const value = info.get()
info.set(true)
 
// Remove a field from its parent object or array.
resolver(state, 'lists.todo.1').delete()
 

By default, if a path cannot be resolved up to the parent, an exception will be thrown.

resolver(state, 'foo') // will not throw
resolver(state, 'foo.bar') // will throw

To never throw, use the onError option. The property exists will be set to false instead. However, all mutation operations (delete, get, set) will throw.

const info = resolver(state, 'foo.bar', {onError:'continue'}) // will not throw
// info.exists === false
info.get() // will throw
