+[](https://nodei.co/npm/chokidar/) +[](https://nodei.co/npm/chokidar/) + +## Why? +Node.js `fs.watch`: + +* Doesn't report filenames on OS X. +* Doesn't report events at all when using editors like Sublime on OS X. +* Often reports events twice. +* Emits most changes as `rename`. +* Has [a lot of other issues](https://github.com/nodejs/node/search?q=fs.watch&type=Issues) +* Does not provide an easy way to recursively watch file trees. + +Node.js `fs.watchFile`: + +* Almost as bad at event handling. +* Also does not provide any recursive watching. +* Results in high CPU utilization. + +Chokidar resolves these problems. + +Initially made for [brunch](http://brunch.io) (an ultra-swift web app build tool), it is now used in +[gulp](https://github.com/gulpjs/gulp/), +[karma](http://karma-runner.github.io), +[PM2](https://github.com/Unitech/PM2), +[browserify](http://browserify.org/), +[webpack](http://webpack.github.io/), +[BrowserSync](http://www.browsersync.io/), +[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode), +and [many others](https://www.npmjs.org/browse/depended/chokidar/). +It has proven itself in production environments. + +## How? +Chokidar does still rely on the Node.js core `fs` module, but when using +`fs.watch` and `fs.watchFile` for watching, it normalizes the events it +receives, often checking for truth by getting file stats and/or dir contents. + +On Mac OS X, chokidar by default uses a native extension exposing the Darwin +`FSEvents` API. This provides very efficient recursive watching compared with +implementations like `kqueue` available on most \*nix platforms. Chokidar still +does have to do some work to normalize the events received that way as well. + +On other platforms, the `fs.watch`-based implementation is the default, which +avoids polling and keeps CPU usage down. Be advised that chokidar will initiate +watchers recursively for everything within scope of the paths that have been +specified, so be judicious about not wasting system resources by watching much +more than needed. + +## Getting started +Install with npm: + + npm install chokidar --save + +Then `require` and use it in your code: + +```javascript +var chokidar = require('chokidar'); + +// One-liner for current directory, ignores .dotfiles +chokidar.watch('.', {ignored: /(^|[\/\\])\../}).on('all', (event, path) => { + console.log(event, path); +}); +``` + +```javascript +// Example of a more typical implementation structure: + +// Initialize watcher. +var watcher = chokidar.watch('file, dir, glob, or array', { + ignored: /(^|[\/\\])\../, + persistent: true +}); + +// Something to use when events are received. +var log = console.log.bind(console); +// Add event listeners. +watcher + .on('add', path => log(`File ${path} has been added`)) + .on('change', path => log(`File ${path} has been changed`)) + .on('unlink', path => log(`File ${path} has been removed`)); + +// More possible events. +watcher + .on('addDir', path => log(`Directory ${path} has been added`)) + .on('unlinkDir', path => log(`Directory ${path} has been removed`)) + .on('error', error => log(`Watcher error: ${error}`)) + .on('ready', () => log('Initial scan complete. Ready for changes')) + .on('raw', (event, path, details) => { + log('Raw event info:', event, path, details); + }); + +// 'add', 'addDir' and 'change' events also receive stat() results as second +// argument when available: http://nodejs.org/api/fs.html#fs_class_fs_stats +watcher.on('change', (path, stats) => { + if (stats) console.log(`File ${path} changed size to ${stats.size}`); +}); + +// Watch new files. +watcher.add('new-file'); +watcher.add(['new-file-2', 'new-file-3', '**/other-file*']); + +// Get list of actual paths being watched on the filesystem +var watchedPaths = watcher.getWatched(); + +// Un-watch some files. +watcher.unwatch('new-file*'); + +// Stop watching. +watcher.close(); + +// Full list of options. See below for descriptions. (do not use this example) +chokidar.watch('file', { + persistent: true, + + ignored: '*.txt', + ignoreInitial: false, + followSymlinks: true, + cwd: '.', + disableGlobbing: false, + + usePolling: true, + interval: 100, + binaryInterval: 300, + alwaysStat: false, + depth: 99, + awaitWriteFinish: { + stabilityThreshold: 2000, + pollInterval: 100 + }, + + ignorePermissionErrors: false, + atomic: true // or a custom 'atomicity delay', in milliseconds (default 100) +}); + +``` + +## API + +`chokidar.watch(paths, [options])` + +* `paths` (string or array of strings). Paths to files, dirs to be watched +recursively, or glob patterns. +* `options` (object) Options object as defined below: + +#### Persistence + +* `persistent` (default: `true`). Indicates whether the process +should continue to run as long as files are being watched. If set to +`false` when using `fsevents` to watch, no more events will be emitted +after `ready`, even if the process continues to run. + +#### Path filtering + +* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition) +Defines files/paths to be ignored. The whole relative or absolute path is +tested, not just filename. If a function with two arguments is provided, it +gets called twice per path - once with a single argument (the path), second +time with two arguments (the path and the +[`fs.Stats`](http://nodejs.org/api/fs.html#fs_class_fs_stats) +object of that path). +* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while +instantiating the watching as chokidar discovers these file paths (before the `ready` event). +* `followSymlinks` (default: `true`). When `false`, only the +symlinks themselves will be watched for changes instead of following +the link references and bubbling events through the link's path. +* `cwd` (no default). The base directory from which watch `paths` are to be +derived. Paths emitted with events will be relative to this. +* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as +literal path names, even if they look like globs. + +#### Performance + +* `usePolling` (default: `false`). +Whether to use fs.watchFile (backed by polling), or fs.watch. If polling +leads to high CPU utilization, consider setting this to `false`. It is +typically necessary to **set this to `true` to successfully watch files over +a network**, and it may be necessary to successfully watch files in other +non-standard situations. Setting to `true` explicitly on OS X overrides the +`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable +to true (1) or false (0) in order to override this option. +* _Polling-specific settings_ (effective when `usePolling: true`) + * `interval` (default: `100`). Interval of file system polling. You may also + set the CHOKIDAR_INTERVAL env variable to override this option. + * `binaryInterval` (default: `300`). Interval of file system + polling for binary files. + ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json)) +* `useFsEvents` (default: `true` on OS X). Whether to use the +`fsevents` watching interface if available. When set to `true` explicitly +and `fsevents` is available this supercedes the `usePolling` setting. When +set to `false` on OS X, `usePolling: true` becomes the default. +* `alwaysStat` (default: `false`). If relying upon the +[`fs.Stats`](http://nodejs.org/api/fs.html#fs_class_fs_stats) +object that may get passed with `add`, `addDir`, and `change` events, set +this to `true` to ensure it is provided even in cases where it wasn't +already available from the underlying watch events. +* `depth` (default: `undefined`). If set, limits how many levels of +subdirectories will be traversed. +* `awaitWriteFinish` (default: `false`). +By default, the `add` event will fire when a file first appears on disk, before +the entire file has been written. Furthermore, in some cases some `change` +events will be emitted while the file is being written. In some cases, +especially when watching for large files there will be a need to wait for the +write operation to finish before responding to a file creation or modification. +Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size, +holding its `add` and `change` events until the size does not change for a +configurable amount of time. The appropriate duration setting is heavily +dependent on the OS and hardware. For accurate detection this parameter should +be relatively high, making file watching much less responsive. +Use with caution. + * *`options.awaitWriteFinish` can be set to an object in order to adjust + timing params:* + * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in + milliseconds for a file size to remain constant before emitting its event. + * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval. + +#### Errors +* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files +that don't have read permissions if possible. If watching fails due to `EPERM` +or `EACCES` with this set to `true`, the errors will be suppressed silently. +* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`). +Automatically filters out artifacts that occur when using editors that use +"atomic writes" instead of writing directly to the source file. If a file is +re-added within 100 ms of being deleted, Chokidar emits a `change` event +rather than `unlink` then `add`. If the default of 100 ms does not work well +for you, you can override it by setting `atomic` to a custom value, in +milliseconds. + +### Methods & Events + +`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`: + +* `.add(path / paths)`: Add files, directories, or glob patterns for tracking. +Takes an array of strings or just one string. +* `.on(event, callback)`: Listen for an FS event. +Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`, +`raw`, `error`. +Additionally `all` is available which gets emitted with the underlying event +name and path for every event other than `ready`, `raw`, and `error`. +* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns. +Takes an array of strings or just one string. +* `.close()`: Removes all listeners from watched files. +* `.getWatched()`: Returns an object representing all the paths on the file +system being watched by this `FSWatcher` instance. The object's keys are all the +directories (using absolute paths unless the `cwd` option was used), and the +values are arrays of the names of the items contained in each directory. + +## CLI + +If you need a CLI interface for your file watching, check out +[chokidar-cli](https://github.com/kimmobrunfeldt/chokidar-cli), allowing you to +execute a command on each change, or get a stdio stream of change events. + +## Install Troubleshooting + +* `npm WARN optional dep failed, continuing fsevents@n.n.n` + * This message is normal part of how `npm` handles optional dependencies and is + not indicative of a problem.
