It is a very fast and lightweight alternative +to kqueue. + +This is a low-level library. For a cross-platform file watching module that +uses fsevents, check out [Chokidar](https://github.com/paulmillr/chokidar). + +## Usage + +```sh +npm install fsevents +``` + +Supports only **Node.js v8.16 and higher**. + +```js +const fsevents = require('fsevents'); + +// To start observation +const stop = fsevents.watch(__dirname, (path, flags, id) => { + const info = fsevents.getInfo(path, flags); +}); + +// To end observation +stop(); +``` + +> **Important note:** The API behaviour is slightly different from typical JS APIs. The `stop` function **must** be +> retrieved and stored somewhere, even if you don't plan to stop the watcher. If you forget it, the garbage collector +> will eventually kick in, the watcher will be unregistered, and your callbacks won't be called anymore. + +The callback passed as the second parameter to `.watch` get's called whenever the operating system detects a +a change in the file system. It takes three arguments: + +###### `fsevents.watch(dirname: string, (path: string, flags: number, id: string) => void): () => Promise` + + * `path: string` - the item in the filesystem that have been changed + * `flags: number` - a numeric value describing what the change was + * `id: string` - an unique-id identifying this specific event + + Returns closer callback which when called returns a Promise resolving when the watcher process has been shut down. + +###### `fsevents.getInfo(path: string, flags: number, id: string): FsEventInfo` + +The `getInfo` function takes the `path`, `flags` and `id` arguments and converts those parameters into a structure +that is easier to digest to determine what the change was. + +The `FsEventsInfo` has the following shape: + +```js +/** + * @typedef {'created'|'modified'|'deleted'|'moved'|'root-changed'|'cloned'|'unknown'} FsEventsEvent + * @typedef {'file'|'directory'|'symlink'} FsEventsType + */ +{ + "event": "created", // {FsEventsEvent} + "path": "file.txt", + "type": "file", // {FsEventsType} + "changes": { + "inode": true, // Had iNode Meta-Information changed + "finder": false, // Had Finder Meta-Data changed + "access": false, // Had access permissions changed + "xattrs": false // Had xAttributes changed + }, + "flags": 0x100000000 +} +``` + +## Changelog + +- v2.3 supports Apple Silicon ARM CPUs +- v2 supports node 8.16+ and reduces package size massively +- v1.2.8 supports node 6+ +- v1.2.7 supports node 4+ + +## Troubleshooting + +- I'm getting `EBADPLATFORM` `Unsupported platform for fsevents` error. +- It's fine, nothing is broken. fsevents is macos-only.
