object-path-plus

object-path-plus is an object-path compatible library that also provides the ability to synthesize values from multiple provided paths. Currently, it only supports the . delimited path format of object-path.

Installation

yarn add object-path-plus

Concatenating values

Concatenation with object-path-plus is very simple, just add a + sign! You can concatenate resolve values from multiple object-paths and you can also concatenate string literals with resolved path values.

const { resolve } = require('object-path-plus');

resolve({ a: { b: 1 }, c: { d: 2 } }, 'a.b + c.d') === 3;

resolve({ a: { b: 'foo' }, c: { d: 'bar' } }, 'a.b + c.d') === 'foobar';

resolve({ a: { b: 1 }, c: { d: 2 } }, 'a.b + " - " + c.d') === '1 - 2';

resolve({ a: { b: 'foo' }, c: { d: 'bar' } }, 'a.b + " " + c.d') === 'foo bar';

resolve({
  a: { b: 'foo' },
  c: { d: 'bar' },
  e: { f: [ 'baz', 'whiz' ] }
}, 'a.b + " " + c.d + " " + e.f.1') === 'foo bar whiz';

resolve({
  a: { b: 'foo' },
  c: { d: 'bar' },
  e: { f: [ 0, 1 ] }
}, 'a.b + " " + c.d + " " + e.f.1') === 'foo bar 1';

Validating object-path-plus paths

You can also test if a path is valid prior to trying to resolve a value with it.

const { validate } = require('object-path-plus');

validate('a.b') === true;

validate('a.b + c.d') === true;

validate('a.b + hello world') === false;
