set-value

Create nested values and any intermediaries using dot notation ('a.b.c') paths.

Install

Install with npm:

$ npm install --save set-value

Usage

var set = require('set-value');
set(object, prop, value);

Params

• object {object}: The object to set value on

• prop {string}: The property to set. Dot-notation may be used.

• value {any}: The value to set on object[prop]

Examples

Updates and returns the given object:

var obj = {};
set(obj, 'a.b.c', 'd');
console.log(obj);
//=> { a: { b: { c: 'd' } } }

Escaping

Escaping with backslashes

Prevent set-value from splitting on a dot by prefixing it with backslashes:

console.log(set({}, 'a\\.b.c', 'd'));
//=> { 'a.b': { c: 'd' } }

console.log(set({}, 'a\\.b\\.c', 'd'));
//=> { 'a.b.c': 'd' }

Escaping with double-quotes or single-quotes

Wrap double or single quotes around the string, or part of the string, that should not be split by set-value:

console.log(set({}, '"a.b".c', 'd'));
//=> { 'a.b': { c: 'd' } }

console.log(set({}, "'a.b'.c", "d"));
//=> { 'a.b': { c: 'd' } }

console.log(set({}, '"this/is/a/.file.path"', 'd'));
//=> { 'this/is/a/file.path': 'd' }

Bracket support

set-value does not split inside brackets or braces:

console.log(set({}, '[a.b].c', 'd'));
//=> { '[a.b]': { c: 'd' } }

console.log(set({}, "(a.b).c", "d"));
//=> { '(a.b)': { c: 'd' } }

console.log(set({}, "<a.b>.c", "d"));
//=> { '<a.b>': { c: 'd' } }

console.log(set({}, "{a..b}.c", "d"));
//=> { '{a..b}': { c: 'd' } }
