+# @parcel/watcher
+
+A native C++ Node module for querying and subscribing to filesystem events. Used by [Parcel 2](https://github.com/parcel-bundler/parcel).
+
+## Features
+
+- **Watch** - subscribe to realtime recursive directory change notifications when files or directories are created, updated, or deleted.
+- **Query** - performantly query for historical change events in a directory, even when your program is not running.
+- **Native** - implemented in C++ for performance and low-level integration with the operating system.
+- **Cross platform** - includes backends for macOS, Linux, Windows, FreeBSD, and Watchman.
+- **Performant** - events are throttled in C++ so the JavaScript thread is not overwhelmed during large filesystem changes (e.g. `git checkout` or `npm install`).
+- **Scalable** - tens of thousands of files can be watched or queried at once with good performance.
+
+## Example
+
+```javascript
+const watcher = require('@parcel/watcher');
+const path = require('path');
+
+// Subscribe to events
+let subscription = await watcher.subscribe(process.cwd(), (err, events) => {
+  console.log(events);
+});
+
+// later on...
+await subscription.unsubscribe();
+
+// Get events since some saved snapshot in the past
+let snapshotPath = path.join(process.cwd(), 'snapshot.txt');
+let events = await watcher.getEventsSince(process.cwd(), snapshotPath);
+
+// Save a snapshot for later
+await watcher.writeSnapshot(process.cwd(), snapshotPath);
+```
+
+## Watching
+
+`@parcel/watcher` supports subscribing to realtime notifications of changes in a directory. It works recursively, so changes in sub-directories will also be emitted.
+
+Events are throttled and coalesced for performance during large changes like `git checkout` or `npm install`, and a single notification will be emitted with all of the events at the end.
+
+Only one notification will be emitted per file. For example, if a file was both created and updated since the last event, you'll get only a `create` event. If a file is both created and deleted, you will not be notifed of that file. Renames cause two events: a `delete` for the old name, and a `create` for the new name.
+
+```javascript
+let subscription = await watcher.subscribe(process.cwd(), (err, events) => {
+  console.log(events);
+});
+```
+
+Events have two properties:
+
+- `type` - the event type: `create`, `update`, or `delete`.
+- `path` - the absolute path to the file or directory.
+
+To unsubscribe from change notifications, call the `unsubscribe` method on the returned subscription object.
+
+```javascript
+await subscription.unsubscribe();
+```
+
+`@parcel/watcher` has the following watcher backends, listed in priority order:
+
+- [FSEvents](https://developer.apple.com/documentation/coreservices/file_system_events) on macOS
+- [Watchman](https://facebook.github.io/watchman/) if installed
+- [inotify](http://man7.org/linux/man-pages/man7/inotify.7.html) on Linux
+- [ReadDirectoryChangesW](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365465%28v%3Dvs.85%29.aspx) on Windows
+- [kqueue](https://man.freebsd.org/cgi/man.cgi?kqueue) on FreeBSD, or as an alternative to FSEvents on macOS
+
+You can specify the exact backend you wish to use by passing the `backend` option. If that backend is not available on the current platform, the default backend will be used instead. See below for the list of backend names that can be passed to the options.
+
+## Querying
+
+`@parcel/watcher` also supports querying for historical changes made in a directory, even when your program is not running. This makes it easy to invalidate a cache and re-build only the files that have changed, for example. It can be **significantly** faster than traversing the entire filesystem to determine what files changed, depending on the platform.
+
+In order to query for historical changes, you first need a previous snapshot to compare to. This can be saved to a file with the `writeSnapshot` function, e.g. just before your program exits.
+
+```javascript
+await watcher.writeSnapshot(dirPath, snapshotPath);
+```
+
+When your program starts up, you can query for changes that have occurred since that snapshot using the `getEventsSince` function.
+
+```javascript
+let events = await watcher.getEventsSince(dirPath, snapshotPath);
+```
+
+The events returned are exactly the same as the events that would be passed to the `subscribe` callback (see above).
+
+`@parcel/watcher` has the following watcher backends, listed in priority order:
+
+- [FSEvents](https://developer.apple.com/documentation/coreservices/file_system_events) on macOS
+- [Watchman](https://facebook.github.io/watchman/) if installed
+- [fts](http://man7.org/linux/man-pages/man3/fts.3.html) (brute force) on Linux and FreeBSD
+- [FindFirstFile](https://docs.microsoft.com/en-us/windows/desktop/api/fileapi/nf-fileapi-findfirstfilea) (brute force) on Windows
+
+The FSEvents (macOS) and Watchman backends are significantly more performant than the brute force backends used by default on Linux and Windows, for example returning results in miliseconds instead of seconds for large directory trees. This is because a background daemon monitoring filesystem changes on those platforms allows us to query cached data rather than traversing the filesystem manually (brute force).
+
+macOS has good performance with FSEvents by default. For the best performance on other platforms, install [Watchman](https://facebook.github.io/watchman/) and it will be used by `@parcel/watcher` automatically.
+
+You can specify the exact backend you wish to use by passing the `backend` option. If that backend is not available on the current platform, the default backend will be used instead. See below for the list of backend names that can be passed to the options.
+
+## Options
+
+All of the APIs in `@parcel/watcher` support the following options, which are passed as an object as the last function argument.
+
+- `ignore` - an array of paths or glob patterns to ignore. uses [`is-glob`](https://github.com/micromatch/is-glob) to distinguish paths from globs. glob patterns are parsed with [`picomatch`](https://github.com/micromatch/picomatch) (see [features](https://github.com/micromatch/picomatch#globbing-features)).
+  - paths can be relative or absolute and can either be files or directories. No events will be emitted about these files or directories or their children.
+  - glob patterns match on relative paths from the root that is watched. No events will be emitted for matching paths.
+- `backend` - the name of an explicitly chosen backend to use. Allowed options are `"fs-events"`, `"watchman"`, `"inotify"`, `"kqueue"`, `"windows"`, or `"brute-force"` (only for querying). If the specified backend is not available on the current platform, the default backend will be used instead.
+
+## WASM
+
+The `@parcel/watcher-wasm` package can be used in place of `@parcel/watcher` on unsupported platforms. It relies on the Node `fs` module, so in non-Node environments such as browsers, an `fs` polyfill will be needed.
+
+**Note**: the WASM implementation is significantly less efficient than the native implementations because it must crawl the file system to watch each directory individually. Use the native `@parcel/watcher` package wherever possible.
+
+```js
+import {subscribe} from '@parcel/watcher-wasm';
+
+// Use the module as documented above.
+subscribe(/* ... */);
+```
+
+## Who is using this?
+
+- [Parcel 2](https://parceljs.org/)
+- [VSCode](https://code.visualstudio.com/updates/v1_62#_file-watching-changes)
+- [Tailwind CSS Intellisense](https://github.com/tailwindlabs/tailwindcss-intellisense)

+
+**Positioning tooltips and popovers is difficult. Popper is here to help!**
+
+Given an element, such as a button, and a tooltip element describing it, Popper
+will automatically put the tooltip in the right place near the button.
+
+It will position _any_ UI element that "pops out" from the flow of your document
+and floats near a target element. The most common example is a tooltip, but it
+also includes popovers, drop-downs, and more. All of these can be generically
+described as a "popper" element.
+
+## Demo
+
+[![Popper visualized](https://i.imgur.com/F7qWsmV.jpg)](https://popper.js.org)
+
+## Docs
+
+- [v2.x (latest)](https://popper.js.org/docs/v2/)
+- [v1.x](https://popper.js.org/docs/v1/)
+
+We've created a
+[Migration Guide](https://popper.js.org/docs/v2/migration-guide/) to help you
+migrate from Popper 1 to Popper 2.
+
+To contribute to the Popper website and documentation, please visit the
+[dedicated repository](https://github.com/popperjs/website).
+
+## Why not use pure CSS?
+
+- **Clipping and overflow issues**: Pure CSS poppers will not be prevented from
+  overflowing clipping boundaries, such as the viewport. It will get partially
+  cut off or overflows if it's near the edge since there is no dynamic
+  positioning logic. When using Popper, your popper will always be positioned in
+  the right place without needing manual adjustments.
+- **No flipping**: CSS poppers will not flip to a different placement to fit
+  better in view if necessary. While you can manually adjust for the main axis
+  overflow, this feature cannot be achieved via CSS alone. Popper automatically
+  flips the tooltip to make it fit in view as best as possible for the user.
+- **No virtual positioning**: CSS poppers cannot follow the mouse cursor or be
+  used as a context menu. Popper allows you to position your tooltip relative to
+  any coordinates you desire.
+- **Slower development cycle**: When pure CSS is used to position popper
+  elements, the lack of dynamic positioning means they must be carefully placed
+  to consider overflow on all screen sizes. In reusable component libraries,
+  this means a developer can't just add the component anywhere on the page,
+  because these issues need to be considered and adjusted for every time. With
+  Popper, you can place your elements anywhere and they will be positioned
+  correctly, without needing to consider different screen sizes, layouts, etc.
+  This massively speeds up development time because this work is automatically
+  offloaded to Popper.
+- **Lack of extensibility**: CSS poppers cannot be easily extended to fit any
+  arbitrary use case you may need to adjust for. Popper is built with
+  extensibility in mind.
+
+## Why Popper?
+
+With the CSS drawbacks out of the way, we now move on to Popper in the
+JavaScript space itself.
+
+Naive JavaScript tooltip implementations usually have the following problems:
+
+- **Scrolling containers**: They don't ensure the tooltip stays with the
+  reference element while scrolling when inside any number of scrolling
+  containers.
+- **DOM context**: They often require the tooltip move outside of its original
+  DOM context because they don't handle `offsetParent` contexts.
+- **Compatibility**: Popper handles an incredible number of edge cases regarding
+  different browsers and environments (mobile viewports, RTL, scrollbars enabled
+  or disabled, etc.). Popper is a popular and well-maintained library, so you
+  can be confident positioning will work for your users on any device.
+- **Configurability**: They often lack advanced configurability to suit any
+  possible use case.
+- **Size**: They are usually relatively large in size, or require an ancient
+  jQuery dependency.
+- **Performance**: They often have runtime performance issues and update the
+  tooltip position too slowly.
+
+**Popper solves all of these key problems in an elegant, performant manner.** It
+is a lightweight ~3 kB library that aims to provide a reliable and extensible
+positioning engine you can use to ensure all your popper elements are positioned
+in the right place.
+
+When you start writing your own popper implementation, you'll quickly run into
+all of the problems mentioned above. These widgets are incredibly common in our
+UIs; we've done the hard work figuring this out so you don't need to spend hours
+fixing and handling numerous edge cases that we already ran into while building
+the library!
+
+Popper is used in popular libraries like Bootstrap, Foundation, Material UI, and
+more. It's likely you've already used popper elements on the web positioned by
+Popper at some point in the past few years.
+
+Since we write UIs using powerful abstraction libraries such as React or Angular
+nowadays, you'll also be glad to know Popper can fully integrate with them and
+be a good citizen together with your other components. Check out `react-popper`
+for the official Popper wrapper for React.
+
+## Installation
+
+### 1. Package Manager
+
+```bash
+# With npm
+npm i @popperjs/core
+
+# With Yarn
+yarn add @popperjs/core
+```
+
+### 2. CDN
+
+```html
+<!-- Development version -->
+<script src="https://unpkg.com/@popperjs/core@2/dist/umd/popper.js"></script>
+
+<!-- Production version -->
+<script src="https://unpkg.com/@popperjs/core@2"></script>
+```
+
+### 3. Direct Download?
+
+Managing dependencies by "directly downloading" them and placing them into your
+source code is not recommended for a variety of reasons, including missing out
+on feat/fix updates easily. Please use a versioning management system like a CDN
+or npm/Yarn.
+
+## Usage
+
+The most straightforward way to get started is to import Popper from the `unpkg`
+CDN, which includes all of its features. You can call the `Popper.createPopper`
+constructor to create new popper instances.
+
+Here is a complete example:

+  const button = document.querySelector('#button');
+  const tooltip = document.querySelector('#tooltip');
+
+  // Pass the button, the tooltip, and some options, and Popper will do the
+  // magic positioning for you:
+  Popper.createPopper(button, tooltip, {
+    placement: 'right',
+  });
+</script>
+```
+
+Visit the [tutorial](https://popper.js.org/docs/v2/tutorial/) for an example of
+how to build your own tooltip from scratch using Popper.
+
+### Module bundlers
+
+You can import the `createPopper` constructor from the fully-featured file:
+
+```js
+import { createPopper } from '@popperjs/core';
+
+const button = document.querySelector('#button');
+const tooltip = document.querySelector('#tooltip');
+
+// Pass the button, the tooltip, and some options, and Popper will do the
+// magic positioning for you:
+createPopper(button, tooltip, {
+  placement: 'right',
+});
+```
+
+All the modifiers listed in the docs menu will be enabled and "just work", so
+you don't need to think about setting Popper up. The size of Popper including
+all of its features is about 5 kB minzipped, but it may grow a bit in the
+future.
+
+#### Popper Lite (tree-shaking)
+
+If bundle size is important, you'll want to take advantage of tree-shaking. The
+library is built in a modular way to allow to import only the parts you really
+need.
+
+```js
+import { createPopperLite as createPopper } from '@popperjs/core';
+```
+
+The Lite version includes the most necessary modifiers that will compute the
+offsets of the popper, compute and add the positioning styles, and add event
+listeners. This is close in bundle size to pure CSS tooltip libraries, and
+behaves somewhat similarly.
+
+However, this does not include the features that makes Popper truly useful.
+
+The two most useful modifiers not included in Lite are `preventOverflow` and
+`flip`:
+
+```js
+import {
+  createPopperLite as createPopper,
+  preventOverflow,
+  flip,
+} from '@popperjs/core';
+
+const button = document.querySelector('#button');
+const tooltip = document.querySelector('#tooltip');
+
+createPopper(button, tooltip, {
+  modifiers: [preventOverflow, flip],
+});
+```
+
+As you make more poppers, you may be finding yourself needing other modifiers
+provided by the library.
+
+See [tree-shaking](https://popper.js.org/docs/v2/performance/#tree-shaking) for more
+information.
+
+## Distribution targets
+
+Popper is distributed in 3 different versions, in 3 different file formats.
+
+The 3 file formats are:
+
+- `esm` (works with `import` syntax — **recommended**)
+- `umd` (works with `<script>` tags or RequireJS)
+- `cjs` (works with `require()` syntax)
+
+There are two different `esm` builds, one for bundler consumers (e.g. webpack,
+Rollup, etc..), which is located under `/lib`, and one for browsers with native
+support for ES Modules, under `/dist/esm`. The only difference within the two,
+is that the browser-compatible version doesn't make use of
+`process.env.NODE_ENV` to run development checks.
+
+The 3 versions are:
+
+- `popper`: includes all the modifiers (features) in one file (**default**);
+- `popper-lite`: includes only the minimum amount of modifiers to provide the
+  basic functionality;
+- `popper-base`: doesn't include any modifier, you must import them separately;
+
+Below you can find the size of each version, minified and compressed with the
+[Brotli compression algorithm](https://medium.com/groww-engineering/enable-brotli-compression-in-webpack-with-fallback-to-gzip-397a57cf9fc6):
+
+<!-- Don't change the labels to use hyphens, it breaks, even when encoded -->
+

+![](https://badge-size.now.sh/https://unpkg.com/@popperjs/core/dist/umd/popper-lite.min.js?compression=brotli&label=popper%20lite)
+![](https://badge-size.now.sh/https://unpkg.com/@popperjs/core/dist/umd/popper-base.min.js?compression=brotli&label=popper%20base)
+
+## Hacking the library
+
+If you want to play with the library, implement new features, fix a bug you
+found, or simply experiment with it, this section is for you!
+
+First of all, make sure to have
+[Yarn installed](https://yarnpkg.com/lang/en/docs/install).
+
+Install the development dependencies:
+
+```bash
+yarn install
+```
+
+And run the development environment:
+
+```bash
+yarn dev
+```
+
+Then, simply open one the development server web page:
+
+```bash
+# macOS and Linux
+open localhost:5000
+
+# Windows
+start localhost:5000
+```
+
+From there, you can open any of the examples (`.html` files) to fiddle with
+them.
+
+Now any change you will made to the source code, will be automatically compiled,
+you just need to refresh the page.
+
+If the page is not working properly, try to go in _"Developer Tools >
+Application > Clear storage"_ and click on "_Clear site data_".  
+To run the examples you need a browser with
+[JavaScript modules via script tag support](https://caniuse.com/#feat=es6-module).
+
+## Test Suite
+
+Popper is currently tested with unit tests, and functional tests. Both of them
+are run by Jest.
+
+### Unit Tests
+
+The unit tests use JSDOM to provide a primitive document object API, they are
+used to ensure the utility functions behave as expected in isolation.
+
+### Functional Tests
+
+The functional tests run with Puppeteer, to take advantage of a complete browser
+environment. They are currently running on Chromium, and Firefox.
+
+You can run them with `yarn test:functional`. Set the `PUPPETEER_BROWSER`
+environment variable to `firefox` to run them on the Mozilla browser.
+
+The assertions are written in form of image snapshots, so that it's easy to
+assert for the correct Popper behavior without having to write a lot of offsets
+comparisons manually.
+
+You can mark a `*.test.js` file to run in the Puppeteer environment by
+prepending a `@jest-environment puppeteer` JSDoc comment to the interested file.
+
+Here's an example of a basic functional test:
+
+```js
+/**
+ * @jest-environment puppeteer
+ * @flow
+ */
+import { screenshot } from '../utils/puppeteer.js';
+
+it('should position the popper on the right', async () => {
+  const page = await browser.newPage();
+  await page.goto(`${TEST_URL}/basic.html`);
+
+  expect(await screenshot(page)).toMatchImageSnapshot();
+});
+```
+
+You can find the complete
+[`jest-puppeteer` documentation here](https://github.com/smooth-code/jest-puppeteer#api),
+and the
+[`jest-image-snapshot` documentation here](https://github.com/americanexpress/jest-image-snapshot#%EF%B8%8F-api).
