Usage

import {create, parse} from 'pathington';

const parsedPath = parse('some[0].deeply["nested path"]');

console.log(parsed); // ['some', 0, 'deeply', 'nested path']

const createdPath = create(['some', 0, 'deeply', 'nested path']);

console.log(createdPath); // 'some[0].deeply["nested path"]'

Methods

parse

parse(path: (Array<number|string>|string)): string

Parse a path into an array of path values.

console.log(parse('simple')); // ['simple']
console.log(parse('dot.notation')); // ['dot', 'notation']
console.log(parse('array[0]')); // ['array', 0]
console.log(parse('array[0].with["quoted keys"]')); // ['array', 0, 'with', 'quoted keys']
console.log(parse('special["%characters*"]')); // ['special', '%characters*']

• If a path string is provided, it will be parsed into an array
• If an array is provided, it will be mapped with the keys normalized

create

create(path: Array<number|string>[, quote="]): string

Create a path string based on the path values passed.

console.log(create(['simple'])); // 'simple'
console.log(create(['array', 0])); // 'array[0]'
console.log(create(['array', 0, 'with', 'quoted keys'])); // 'array[0].with["quoted keys"]'
console.log(create(['special', '%characters*'])); // 'special["%charactres*"]'

Optionally, you can pass in the quote string to use instead of ". Valid values are backtick or single-quote.

console.log(create(['quoted keys'], "'")); // ['quoted keys']
