wtchr

Simple file/directory watcher. (Node.js)

API

It's quite simple to create a wtchr for a directory.

wtchr object

wtchr(path, [options]);

path

• an absolute dircetory path

options:

• persistent (boolean) default: true
• interval (integer) default: 500
• ignore (regexp) default: /(\/\.DS_Store$)/

Example:

var watch = wtchr('/my/watch/base/directory');

wtchr events

Wtchr provides simple event bindings. The event API is quite similar to jQuery events, so most of JS developers are familiar with it.

bind an event

.on(type, [selector], handler(path, curr lstat, prev lstat))

unbind an event

.off(type, [selector], [handler(path, curr lstat, prev lstat)])

type:

• one of the 3 supported types create / change / delete

selector

• a minimatch path selector (simply a filter)

handle:

• a event handler

Example:

var watch = wtchr('/my/watch/base/directory')

watch.on("create", "*.js", function (path, curr, prev) {
  console.log("New file: " + path);
});

watch.off("create");

Chaining:

wtchr('/my/watch/base/directory')
  .on("create", "*.js", function (path, curr, prev) {
    console.log("New file: " + path);
  })
  .on("change", "*.js", function (path, curr, prev) {
    console.log("File changed: " + path);
  })
  .on("delete", "*.js", function (path, curr, prev) {
    console.log("File deleted: " + path);
  })
  .off("create")
  .off("delete");

stop wtchr

Simply destroy the wtchr object with the destroy method.

.destroy()

Example:

var watch = wtchr('/my/watch/base/directory')

watch.destroy();
