Uses `Object.defineProperty` when available; falls back to standard assignment in older engines. Existing properties are not overridden. Accepts a map of property names to a predicate that, when true, force-overrides. ## Example ```js var define = require('define-properties'); var assert = require('assert'); var obj = define({ a: 1, b: 2 }, { a: 10, b: 20, c: 30 }); assert(obj.a === 1); assert(obj.b === 2); assert(obj.c === 30); if (define.supportsDescriptors) { assert.deepEqual(Object.keys(obj), ['a', 'b']); assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'c'), { configurable: true, enumerable: false, value: 30, writable: false }); } ``` Then, with predicates: ```js var define = require('define-properties'); var assert = require('assert'); var obj = define({ a: 1, b: 2, c: 3 }, { a: 10, b: 20, c: 30 }, { a: function () { return false; }, b: function () { return true; } }); assert(obj.a === 1); assert(obj.b === 20); assert(obj.c === 3); if (define.supportsDescriptors) { assert.deepEqual(Object.keys(obj), ['a', 'c']); assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'b'), { configurable: true, enumerable: false, value: 20, writable: false }); } ``` ## Tests Simply clone the repo, `npm install`, and run `npm test` [package-url]: https://npmjs.org/package/define-properties [npm-version-svg]: http://versionbadg.es/ljharb/define-properties.svg [travis-svg]: https://travis-ci.org/ljharb/define-properties.svg [travis-url]: https://travis-ci.org/ljharb/define-properties [deps-svg]: https://david-dm.org/ljharb/define-properties.svg [deps-url]: https://david-dm.org/ljharb/define-properties [dev-deps-svg]: https://david-dm.org/ljharb/define-properties/dev-status.svg [dev-deps-url]: https://david-dm.org/ljharb/define-properties#info=devDependencies [testling-svg]: https://ci.testling.com/ljharb/define-properties.png [testling-url]: https://ci.testling.com/ljharb/define-properties [npm-badge-png]: https://nodei.co/npm/define-properties.png?downloads=true&stars=true [license-image]: http://img.shields.io/npm/l/define-properties.svg [license-url]: LICENSE [downloads-image]: http://img.shields.io/npm/dm/define-properties.svg [downloads-url]: http://npm-stat.com/charts.html?package=define-properties package/test/index.js000644 0000005764 3560116604 011720 0ustar00000000 000000 'use strict'; var define = require('../'); var test = require('tape'); var keys = require('object-keys'); var arePropertyDescriptorsSupported = function () { var obj = { a: 1 }; try { Object.defineProperty(obj, 'x', { value: obj }); return obj.x === obj; } catch (e) { /* this is IE 8. */ return false; } }; var descriptorsSupported = !!Object.defineProperty && arePropertyDescriptorsSupported(); var hasSymbols = typeof Symbol === 'function' && typeof Symbol('foo') === 'symbol'; test('defineProperties', function (dt) { dt.test('with descriptor support', { skip: !descriptorsSupported }, function (t) { var getDescriptor = function (value) { return { configurable: true, enumerable: false, value: value, writable: true }; }; var obj = { a: 1, b: 2, c: 3 }; t.deepEqual(keys(obj), ['a', 'b', 'c'], 'all literal-set keys start enumerable'); define(obj, { b: 3, c: 4, d: 5 }); t.deepEqual(obj, { a: 1, b: 2, c: 3 }, 'existing properties were not overridden'); t.deepEqual(Object.getOwnPropertyDescriptor(obj, 'd'), getDescriptor(5), 'new property "d" was added and is not enumerable'); t.deepEqual(['a', 'b', 'c'], keys(obj), 'new keys are not enumerable'); define(obj, { a: 2, b: 3, c: 4 }, { a: function () { return true; }, b: function () { return false; } }); t.deepEqual(obj, { b: 2, c: 3 }, 'properties only overriden when predicate exists and returns true'); t.deepEqual(Object.getOwnPropertyDescriptor(obj, 'd'), getDescriptor(5), 'existing property "d" remained and is not enumerable'); t.deepEqual(Object.getOwnPropertyDescriptor(obj, 'a'), getDescriptor(2), 'existing property "a" was overridden and is not enumerable'); t.deepEqual(['b', 'c'], keys(obj), 'overridden keys are not enumerable'); t.end(); }); dt.test('without descriptor support', { skip: descriptorsSupported }, function (t) { var obj = { a: 1, b: 2, c: 3 }; define(obj, { b: 3, c: 4, d: 5 }); t.deepEqual(obj, { a: 1, b: 2, c: 3, d: 5 }, 'existing properties were not overridden, new properties were added'); define(obj, { a: 2, b: 3, c: 4 }, { a: function () { return true; }, b: function () { return false; } }); t.deepEqual(obj, { a: 2, b: 2, c: 3, d: 5 }, 'properties only overriden when predicate exists and returns true'); t.end(); }); dt.end(); }); test('symbols', { skip: !hasSymbols }, function (t) { var sym = Symbol('foo'); var obj = {}; var aValue = {}; var bValue = {}; var properties = { a: aValue }; properties[sym] = bValue; define(obj, properties); t.deepEqual(Object.keys(obj), [], 'object has no enumerable keys'); t.deepEqual(Object.getOwnPropertyNames(obj), ['a'], 'object has non-enumerable "a" key'); t.deepEqual(Object.getOwnPropertySymbols(obj), [sym], 'object has non-enumerable symbol key'); t.equal(obj.a, aValue, 'string keyed value is defined'); t.equal(obj[sym], bValue, 'symbol keyed value is defined'); t.end(); });
