File watcher using RxJS. Wraps the chokidar.watch function.
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.
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 thecwd
property in the options passed to the watch function). -
name
- the file name relative to thebasedir
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 (thebasedir
plus thename
). -
basename
- returns the base filename without any path. -
dirname
- return the full path, without the file name. -
extname
- returns the file extension.
