+# @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 [`micromatch`](https://github.com/micromatch/micromatch) (see [features](https://github.com/micromatch/micromatch#matching-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(/* ... */);
+```

+# napi-wasm
+
+An implementation of the [napi](https://nodejs.org/api/n-api.html) API for WASM. Enables using some native Node modules in browsers and other environments.
+
+## Setup
+
+To use napi-wasm, there are a few requirements:
+
+1. Configure your linker to export an indirect function table. With ldd, this is the `--export-table` flag. This enables JavaScript to call callback functions registered by WASM. It is exposed in the WebAssembly exports as `__indirect_function_table`.
+2. Export a function from your WASM build named `napi_register_module_v1` (Node's default), or `napi_register_wasm_v1` for WASM-specific builds. This is called during initialization to setup the `exports` object for your module. It receives an environment and an exports object pointer as arguments, which you can add properties to.
+3. Include a function named `napi_wasm_malloc` in your WASM build. This is called from JavaScript by napi-wasm to allocate memory in the WASM heap. It should accept a `uint32` size argument indicating the number of bytes to allocate, and return a `uint8` pointer to allocated memory.
+4. Compile for the `wasm32-unknown-unknown` target.
+
+### In Rust
+
+The above steps should apply for any programming language, but here's an example in Rust. First, define a `napi_wasm_malloc` function so JavaScript can allocate memory in the WASM heap using the default allocator.
+
+```rust
+use std::alloc::{alloc, Layout};
+
+#[no_mangle]
+pub extern "C" fn napi_wasm_malloc(size: usize) -> *mut u8 {
+  let align = std::mem::align_of::<usize>();
+  if let Ok(layout) = Layout::from_size_align(size, align) {
+    unsafe {
+      if layout.size() > 0 {
+        let ptr = alloc(layout);
+        if !ptr.is_null() {
+          return ptr;
+        }
+      } else {
+        return align as *mut u8;
+      }
+    }
+  }
+
+  std::process::abort();
+}
+```
+
+Next, implement `napi_register_wasm_v1` to register your module exports. We'll use the [napi-rs](https://github.com/napi-rs/napi-rs) bindings in this example to make it a bit nicer than calling C APIs directly. Note that the napi-rs `#[module_exports]` macro currently doesn't work in WASM because Rust doesn't support ctor setup functions in WASM targets yet, so we'll need to do this manually.
+
+```rust
+use napi::{Env, JsObject, NapiValue};
+
+#[no_mangle]
+pub unsafe extern "C" fn napi_register_wasm_v1(raw_env: napi::sys::napi_env, raw_exports: napi::sys::napi_value) {
+  let env = Env::from_raw(raw_env);
+  let exports = JsObject::from_raw_unchecked(raw_env, raw_exports);
+
+  exports.create_named_method("transform", transform);
+}
+
+#[js_function(1)]
+fn transform(ctx: CallContext) -> napi::Result<JsUnknown> {
+  // ...
+}
+```
+
+To compile, you need to export a function table and use the correct target.
+
+```shell
+ RUSTFLAGS="-C link-arg=--export-table" cargo build --target wasm32-unknown-unknown
+```
+
+This will output a file in `target/wasm32-unknown-unknown/debug/YOUR_CRATE.wasm` which you can load in a JavaScript environment.
+
+You can also put the rust flags in a `.cargo/config.toml` file so you don't need to provide the environment variable each time you run `cargo build`.
+
+```toml
+[target.wasm32-unknown-unknown]
+rustflags = ["-C", "link-arg=--export-table"]
+```
+
+### Loading
+
+To load a WASM file and initialize a napi environment, you'll need to import the `napi-wasm` package. You instantiate a WASM module as usual, providing `napi` as the `env` import key. This provides the napi functions for your WASM module to use.
+
+Then, pass the WASM instance to the `Environment` constructor to setup a napi environment. This will call `napi_register_wasm_v1` or `napi_register_module_v1` to setup the exports object. Then you can call functions on the exports object as you would in Node.
+
+```js
+import { Environment, napi } from 'napi-wasm';
+
+// Construct a URL and instantiate a WebAssembly module as usual.
+const url = new URL('path/to/lib.wasm', import.meta.url);
+const { instance } = await WebAssembly.instantiateStreaming(fetch(url), {
+  env: napi
+});
+
+// Create an environment.
+let env = new Environment(instance);
+let exports = env.exports;
+
+// Use exports as usual!
+exports.transform({
+  // ...
+});
+```
+
+When you are done with an `Environment`, call the `destroy()` function to clean up memory.
