watch-rx

| Linux/OSX | Windows | | --- | --- | | | |

File watcher using RxJS. Wraps the chokidar.watch function.

Usage

Install from NPM

npm install --save watch-rx

Use it as an observable.

var watchRx = require('watch-rx');

var subscription = watchRx(pattern, options)
    .subscribe(
        function(file) {
            // .. do something with file
            console.log(file.fullname);
        },
        function(err) {
            // ... error handling
        },
        function() {
            // ... end of files
        });

// Some time later ...
subscription.unsubscribe();

This module wraps the chokidar.watch function in an observable, so the pattern and options parameters are the same.

Output

The observable returns an object with three properties:

• event - the event that occurred, add, addDir, change, unlink, unlinkDir.

• basedir - the base directory the pattern is relative to (corresponds to the cwd property in the options passed to the watch function).

• name - the file name relative to the basedir property.

The object also supports a number of calculated properties to get additional information about the file.

• fullname - returns the full name of the file (the basedir plus the name).

• basename - returns the base filename without any path.

• dirname - return the full path, without the file name.

• extname - returns the file extension.
