Object

Overview

The framework re-exports lodash-es via the facade for object manipulation. These methods handle picking, omitting, merging, and deep property access.

Import

import { lodash } from "@/framework/facade.js";

Common Methods

Method	Purpose
lodash.pick(object, paths)	Creates an object with the picked keys
lodash.pickBy(object, predicate)	Picks keys based on predicate
lodash.omit(object, paths)	Creates an object omitting the specified keys
lodash.omitBy(object, predicate)	Omits keys based on predicate
lodash.get(object, path, defaultValue)	Gets nested value by dot/bracket path
lodash.set(object, path, value)	Sets nested value (mutates)
lodash.has(object, path)	Checks if path exists in the object
lodash.merge(object, sources)	Deep merges source objects (mutates)
lodash.mergeWith(object, sources, customizer)	Deep merge with customizer
lodash.assign(object, sources)	Copies own enumerable properties (mutates)
lodash.assignIn(object, sources)	Copies own and inherited properties
lodash.defaults(object, sources)	Assigns values from sources if undefined
lodash.defaultsDeep(object, sources)	Deep version of defaults
lodash.keys(object)	Returns enumerable property names
lodash.values(object)	Returns property values
lodash.entries(object)	Returns [key, value] pairs (alias: toPairs)
lodash.mapKeys(object, iteratee)	Transforms keys
lodash.mapValues(object, iteratee)	Transforms values
lodash.invert(object)	Swaps keys and values
lodash.findKey(object, predicate)	Finds key of first matching value
lodash.forOwn(object, iteratee)	Iterates over own properties
lodash.result(object, path, defaultValue)	Resolves the value at path (calls if function)

Usage

import { lodash } from "@/framework/facade.js";

const user = {
  name: "Alice",
  email: "alice@example.com",
  password: "secret",
  age: 25,
};

// Pick safe fields
lodash.pick(user, ["name", "email"]);
// { name: "Alice", email: "alice@example.com" }

// Omit sensitive fields
lodash.omit(user, ["password"]);
// { name: "Alice", email: "alice@example.com", age: 25 }

// Deep property access
const data = { a: { b: { c: 42 } } };
lodash.get(data, "a.b.c");
// 42

lodash.get(data, "x.y.z", "default");
// "default"

// Deep merge
const defaults = { theme: "light", cache: { ttl: 300 } };
const config = { cache: { ttl: 600 } };
lodash.merge(defaults, config);
// { theme: "light", cache: { ttl: 600 } }
