Replace lodash/lodash-es with native JavaScript and lightweight alternatives

[Copilot]

Removes lodash/lodash-es dependency across all packages, replacing with native JavaScript methods, VueUse composables, and minimal libraries (fast-deep-equal, rfdc).

Replacements by category

Array/Object methods → Native JS

• indexOf, find, filter, map → Array.prototype methods
• keyBy → Object.fromEntries with map
• isEmpty → Object.keys().length
• difference → filter with Set
• compact → filter(Boolean) with type guard
• partition → Custom forEach implementation

Async utilities → VueUse

• throttle → useThrottleFn (components, hub-features)
• debounce → useDebounceFn (components) or custom helper (jsonforms)

Specialized functions → Minimal libraries

• cloneDeep → rfdc package
• isEqual → fast-deep-equal package
• uniqueId → Custom counter implementations
• maxBy → Manual loop
• merge → Spread operator with manual header merging

Example changes

// Before
import { keyBy, partition } from "lodash-es";
const map = computed(() => keyBy(items, "id"));
const [included, excluded] = partition(array, predicate);

// After
const map = computed(() => 
  Object.fromEntries(items.map(item => [item.id, item]))
);
const included = [], excluded = [];
array.forEach(item => {
  (predicate(item) ? included : excluded).push(item);
});

// Before
import { throttle } from "lodash-es";
const handler = throttle(fn, 100);

// After
import { useThrottleFn } from "@vueuse/core";
const handler = useThrottleFn(fn, 100);

Packages removed

• lodash-es from components, hub-features, jsonforms
• @types/lodash-es from root devDependencies

Packages added

• fast-deep-equal@3.1.3 (isEqual replacement, no vulnerabilities)
• rfdc@1.4.1 (cloneDeep replacement, no vulnerabilities)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• vueuse.org
  • Triggering command: curl -s REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Replace all lodash/lodash-es usages with native code following https://raw.githubusercontent.com/you-dont-need/You-Dont-Need-Lodash-Underscore/refs/heads/master/README.md
Use fast-deep-equal/es6 npm package if a deep equal check is required.
Use rfdc npm package for cloneDeep.
Make sure tests still run (pnpm test:unit), linting passes (pnpm lint:js --fix) and type-check passed (pnpm type-check).
