+# CSSStyleDeclaration
+
+A Node.js implementation of the CSS Object Model [`CSSStyleDeclaration` class](https://drafts.csswg.org/cssom/#the-cssstyledeclaration-interface).
+
+## Background
+
+This package is an extension of the `CSSStyleDeclaration` class in Nikita Vasilyev's [CSSOM](https://github.com/NV/CSSOM), with added support for modern specifications. The primary use case is for testing browser code in a Node environment.
+
+It was originally created by Chad Walker, it is now maintained by the jsdom community.
+
+Bug reports and pull requests are welcome.

+# lru-cache
+
+A cache object that deletes the least-recently-used items.
+
+Specify a max number of the most recently used items that you
+want to keep, and this cache will keep that many of the most
+recently accessed items.
+
+This is not primarily a TTL cache, and does not make strong TTL
+guarantees. There is no preemptive pruning of expired items by
+default, but you _may_ set a TTL on the cache or on a single
+`set`. If you do so, it will treat expired items as missing, and
+delete them when fetched. If you are more interested in TTL
+caching than LRU caching, check out
+[@isaacs/ttlcache](http://npm.im/@isaacs/ttlcache).
+
+As of version 7, this is one of the most performant LRU
+implementations available in JavaScript, and supports a wide
+diversity of use cases. However, note that using some of the
+features will necessarily impact performance, by causing the
+cache to have to do more work. See the "Performance" section
+below.
+
+## Installation
+
+```bash
+npm install lru-cache --save
+```
+
+## Usage
+
+```js
+// hybrid module, either works
+import { LRUCache } from 'lru-cache'
+// or:
+const { LRUCache } = require('lru-cache')
+// or in minified form for web browsers:
+import { LRUCache } from 'http://unpkg.com/lru-cache@9/dist/mjs/index.min.mjs'
+
+// At least one of 'max', 'ttl', or 'maxSize' is required, to prevent
+// unsafe unbounded storage.
+//
+// In most cases, it's best to specify a max for performance, so all
+// the required memory allocation is done up-front.
+//
+// All the other options are optional, see the sections below for
+// documentation on what each one does.  Most of them can be
+// overridden for specific items in get()/set()
+const options = {
+  max: 500,
+
+  // for use with tracking overall storage size
+  maxSize: 5000,
+  sizeCalculation: (value, key) => {
+    return 1
+  },
+
+  // for use when you need to clean up something when objects
+  // are evicted from the cache
+  dispose: (value, key, reason) => {
+    freeFromMemoryOrWhatever(value)
+  },
+
+  // for use when you need to know that an item is being inserted
+  // note that this does NOT allow you to prevent the insertion,
+  // it just allows you to know about it.
+  onInsert: (value, key, reason) => {
+    logInsertionOrWhatever(key, value)
+  },
+
+  // how long to live in ms
+  ttl: 1000 * 60 * 5,
+
+  // return stale items before removing from cache?
+  allowStale: false,
+
+  updateAgeOnGet: false,
+  updateAgeOnHas: false,
+
+  // async method to use for cache.fetch(), for
+  // stale-while-revalidate type of behavior
+  fetchMethod: async (key, staleValue, { options, signal, context }) => {},
+}
+
+const cache = new LRUCache(options)
+
+cache.set('key', 'value')
+cache.get('key') // "value"
+
+// non-string keys ARE fully supported
+// but note that it must be THE SAME object, not
+// just a JSON-equivalent object.
+var someObject = { a: 1 }
+cache.set(someObject, 'a value')
+// Object keys are not toString()-ed
+cache.set('[object Object]', 'a different value')
+assert.equal(cache.get(someObject), 'a value')
+// A similar object with same keys/values won't work,
+// because it's a different object identity
+assert.equal(cache.get({ a: 1 }), undefined)
+
+cache.clear() // empty the cache
+```
+
+If you put more stuff in the cache, then less recently used items
+will fall out. That's what an LRU cache is.
+
+For full description of the API and all options, please see [the
+LRUCache typedocs](https://isaacs.github.io/node-lru-cache/)
+
+## Storage Bounds Safety
+
+This implementation aims to be as flexible as possible, within
+the limits of safe memory consumption and optimal performance.
+
+At initial object creation, storage is allocated for `max` items.
+If `max` is set to zero, then some performance is lost, and item
+count is unbounded. Either `maxSize` or `ttl` _must_ be set if
+`max` is not specified.
+
+If `maxSize` is set, then this creates a safe limit on the
+maximum storage consumed, but without the performance benefits of
+pre-allocation. When `maxSize` is set, every item _must_ provide
+a size, either via the `sizeCalculation` method provided to the
+constructor, or via a `size` or `sizeCalculation` option provided
+to `cache.set()`. The size of every item _must_ be a positive
+integer.
+
+If neither `max` nor `maxSize` are set, then `ttl` tracking must
+be enabled. Note that, even when tracking item `ttl`, items are
+_not_ preemptively deleted when they become stale, unless
+`ttlAutopurge` is enabled. Instead, they are only purged the
+next time the key is requested. Thus, if `ttlAutopurge`, `max`,
+and `maxSize` are all not set, then the cache will potentially
+grow unbounded.
+
+In this case, a warning is printed to standard error. Future
+versions may require the use of `ttlAutopurge` if `max` and
+`maxSize` are not specified.
+
+If you truly wish to use a cache that is bound _only_ by TTL
+expiration, consider using a `Map` object, and calling
+`setTimeout` to delete entries when they expire. It will perform
+much better than an LRU cache.
+
+Here is an implementation you may use, under the same
+[license](./LICENSE) as this package:
+
+```js
+// a storage-unbounded ttl cache that is not an lru-cache
+const cache = {
+  data: new Map(),
+  timers: new Map(),
+  set: (k, v, ttl) => {
+    if (cache.timers.has(k)) {
+      clearTimeout(cache.timers.get(k))
+    }
+    cache.timers.set(
+      k,
+      setTimeout(() => cache.delete(k), ttl),
+    )
+    cache.data.set(k, v)
+  },
+  get: k => cache.data.get(k),
+  has: k => cache.data.has(k),
+  delete: k => {
+    if (cache.timers.has(k)) {
+      clearTimeout(cache.timers.get(k))
+    }
+    cache.timers.delete(k)
+    return cache.data.delete(k)
+  },
+  clear: () => {
+    cache.data.clear()
+    for (const v of cache.timers.values()) {
+      clearTimeout(v)
+    }
+    cache.timers.clear()
+  },
+}
+```
+
+If that isn't to your liking, check out
+[@isaacs/ttlcache](http://npm.im/@isaacs/ttlcache).
+
+## Storing Undefined Values
+
+This cache never stores undefined values, as `undefined` is used
+internally in a few places to indicate that a key is not in the
+cache.
+
+You may call `cache.set(key, undefined)`, but this is just
+an alias for `cache.delete(key)`. Note that this has the effect
+that `cache.has(key)` will return _false_ after setting it to
+undefined.
+
+```js
+cache.set(myKey, undefined)
+cache.has(myKey) // false!
+```
+
+If you need to track `undefined` values, and still note that the
+key is in the cache, an easy workaround is to use a sigil object
+of your own.
+
+```js
+import { LRUCache } from 'lru-cache'
+const undefinedValue = Symbol('undefined')
+const cache = new LRUCache(...)
+const mySet = (key, value) =>
+  cache.set(key, value === undefined ? undefinedValue : value)
+const myGet = (key, value) => {
+  const v = cache.get(key)
+  return v === undefinedValue ? undefined : v
+}
+```
+
+## Performance
+
+As of January 2022, version 7 of this library is one of the most
+performant LRU cache implementations in JavaScript.
+
+Benchmarks can be extremely difficult to get right. In
+particular, the performance of set/get/delete operations on
+objects will vary _wildly_ depending on the type of key used. V8
+is highly optimized for objects with keys that are short strings,
+especially integer numeric strings. Thus any benchmark which
+tests _solely_ using numbers as keys will tend to find that an
+object-based approach performs the best.
+
+Note that coercing _anything_ to strings to use as object keys is
+unsafe, unless you can be 100% certain that no other type of
+value will be used. For example:
+
+```js
+const myCache = {}
+const set = (k, v) => (myCache[k] = v)
+const get = k => myCache[k]
+
+set({}, 'please hang onto this for me')
+set('[object Object]', 'oopsie')
+```
+
+Also beware of "Just So" stories regarding performance. Garbage
+collection of large (especially: deep) object graphs can be
+incredibly costly, with several "tipping points" where it
+increases exponentially. As a result, putting that off until
+later can make it much worse, and less predictable. If a library
+performs well, but only in a scenario where the object graph is
+kept shallow, then that won't help you if you are using large
+objects as keys.
+
+In general, when attempting to use a library to improve
+performance (such as a cache like this one), it's best to choose
+an option that will perform well in the sorts of scenarios where
+you'll actually use it.
+
+This library is optimized for repeated gets and minimizing
+eviction time, since that is the expected need of a LRU. Set
+operations are somewhat slower on average than a few other
+options, in part because of that optimization. It is assumed
+that you'll be caching some costly operation, ideally as rarely
+as possible, so optimizing set over get would be unwise.
+
+If performance matters to you:
+
+1. If it's at all possible to use small integer values as keys,
+   and you can guarantee that no other types of values will be
+   used as keys, then do that, and use a cache such as
+   [lru-fast](https://npmjs.com/package/lru-fast), or
+   [mnemonist's
+   LRUCache](https://yomguithereal.github.io/mnemonist/lru-cache)
+   which uses an Object as its data store.
+
+2. Failing that, if at all possible, use short non-numeric
+   strings (ie, less than 256 characters) as your keys, and use
+   [mnemonist's
+   LRUCache](https://yomguithereal.github.io/mnemonist/lru-cache).
+
+3. If the types of your keys will be anything else, especially
+   long strings, strings that look like floats, objects, or some
+   mix of types, or if you aren't sure, then this library will
+   work well for you.
+
+   If you do not need the features that this library provides
+   (like asynchronous fetching, a variety of TTL staleness
+   options, and so on), then [mnemonist's
+   LRUMap](https://yomguithereal.github.io/mnemonist/lru-map) is
+   a very good option, and just slightly faster than this module
+   (since it does considerably less).
+
+4. Do not use a `dispose` function, size tracking, or especially
+   ttl behavior, unless absolutely needed. These features are
+   convenient, and necessary in some use cases, and every attempt
+   has been made to make the performance impact minimal, but it
+   isn't nothing.
+
+## Testing
+
+When writing tests that involve TTL-related functionality, note
+that this module creates an internal reference to the global
+`performance` or `Date` objects at import time. If you import it
+statically at the top level, those references cannot be mocked or
+overridden in your test environment.
+
+To avoid this, dynamically import the package within your tests
+so that the references are captured after your mocks are applied.
+For example:
+
+```ts
+// ❌ Not recommended
+import { LRUCache } from 'lru-cache'
+// mocking timers, e.g. jest.useFakeTimers()
+
+// ✅ Recommended for TTL tests
+// mocking timers, e.g. jest.useFakeTimers()
+const { LRUCache } = await import('lru-cache')
+```
+
+This ensures that your mocked timers or time sources are
+respected when testing TTL behavior.
+
+Additionally, you can pass in a `perf` option when creating your
+LRUCache instance. This option accepts any object with a `now`
+method that returns a number.
+
+For example, this would be a very bare-bones time-mocking system
+you could use in your tests, without any particular test
+framework:
+
+```ts
+import { LRUCache } from 'lru-cache'
+
+let myClockTime = 0
+
+const cache = new LRUCache<string>({
+  max: 10,
+  ttl: 1000,
+  perf: {
+    now: () => myClockTime,
+  },
+})
+
+// run tests, updating myClockTime as needed
+```
+
+## Breaking Changes in Version 7
+
+This library changed to a different algorithm and internal data
+structure in version 7, yielding significantly better
+performance, albeit with some subtle changes as a result.
+
+If you were relying on the internals of LRUCache in version 6 or
+before, it probably will not work in version 7 and above.
+
+## Breaking Changes in Version 8
+
+- The `fetchContext` option was renamed to `context`, and may no
+  longer be set on the cache instance itself.
+- Rewritten in TypeScript, so pretty much all the types moved
+  around a lot.
+- The AbortController/AbortSignal polyfill was removed. For this
+  reason, **Node version 16.14.0 or higher is now required**.
+- Internal properties were moved to actual private class
+  properties.
+- Keys and values must not be `null` or `undefined`.
+- Minified export available at `'lru-cache/min'`, for both CJS
+  and MJS builds.
+
+## Breaking Changes in Version 9
+
+- Named export only, no default export.
+- AbortController polyfill returned, albeit with a warning when
+  used.
+
+## Breaking Changes in Version 10
+
+- `cache.fetch()` return type is now `Promise<V | undefined>`
+  instead of `Promise<V | void>`. This is an irrelevant change
+  practically speaking, but can require changes for TypeScript
+  users.
+
+For more info, see the [change log](CHANGELOG.md).
